General safety rules

WARNING. Read all safety warnings and all instructions.

Failure to follow the warnings and instructions may result in

electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-

operated (corded) power tool or battery-operated (cordless)

power tool.

1) Work area safety

a) Keep work area clean and well lit.

Cluttered or dark

areas invite accidents.

b) Do not operate power tools in explosive

atmospheres,

such as in the presence of flammable

liquids, gases or dust. Power tools create sparks which

may ignite the dust or fumes.

c) Keep children and bystanders away while operating a

power tool.

Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify

the plug in any way.

Do not use any adapter plugs with

earthed (grounded) power tools. Unmodified plugs and

matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded

surfaces, such as pipes, radiators, ranges and

refrigerators.

There is an increased risk of electric

shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of

electric shock.

d) Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.

Keep cord away from heat, oil, sharp edges or

moving parts.

Damaged or entangled cords increase

the risk of electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use.

Use of a cord

suitable for outdoor use reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating a power tool. Do not

use a power tool while you are tired or under the

influence of drugs, alcohol or medication.

A moment

of inattention while operating power tools may result in

serious personal injury.

b) Use personal protective equipment. Always wear eye

protection.

Protective equipment such as dust mask,

non-skid safety shoes, hard hat, or hearing protection used

for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch

is in the off-position before connecting to power

source and/or battery pack, picking up or carrying

the tool. Carrying power tools with your finger on the

switch or energising power tools that have the switch

on invites accidents.

d) Remove any adjusting key or wrench before

turning the power tool on.

A wrench or a key left

attached to a rotating part of the power tool may result

in personal injury.

e) Do not overreach. Keep proper footing and balance

at all times.

This enables better control of the power tool

in unexpected situations.

f ) Dress properly. Do not wear loose clothing or

jewellery. Keep your hair, clothing and gloves away

from moving parts.

Loose clothes, jewellery or long hair

can be caught in moving parts.

g) If devices are provided for the connection of dust

extraction and collection facilities, ensure these are

connected and properly used.

Use of dust collection

can reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power

tool for your application.

The correct power tool will

do the job better and safer at the rate for which it was

designed.

b) Do not use the power tool if the switch does not turn

it on and off.

Any power tool that cannot be controlled

with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or

the battery pack from the power tool before making

any adjustments, changing accessories, or storing

power tools. Such preventive safety measures reduce

the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children

and do not allow persons unfamiliar with the power

tool or these instructions to operate the power tool.

Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or

binding of moving parts, breakage of parts and any

other condition that may affect the power tool’s

operation. If damaged, have the power tool repaired

before use.

Many accidents are caused by poorly

maintained power tools.

f ) Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are

less likely to bind and are easier to control.

g) Use the power tool, accessories and tool bits etc.

in accordance with these instructions, taking into

account the working conditions and the work to be

performed. Use of the power tool for operations different

from those intended could result in a hazardous situation.

h) This appliance is not intended for use by persons

(including children) with reduced physical, sensory

or mental capabilities, or lack of experience and

knowledge, unless they have been given supervision or

instruction concerning use of the appliance by a person

responsible for their safety.

i) Children should be supervised to ensure that they do

not play with the appliance.

5) Service

a) Have your power tool serviced by a qualified repair

person using only identical replacement parts.

This

will ensure that the safety of the power tool is maintained.

b) If the supply cord is damaged, it must be replaced by

the manufacturer,

its service agent or similarly qualified

persons in order to avoid a hazard.

The wetstone sharpener is shipped partly assembled,

leaving the sharpening wheel, the tool support bar, tool

holder and water reservoir to be installed prior to use.

CAUTION. Always ensure that the wetstone sharpener is

switched off and the plug is removed from the power point

before making any adjustments.

Fitting of the sharpening wheel

1. Remove the sharpening wheel

nut

(13), along with one of the

large flange washers from the

spindle of the sharpener. The

wheel nut (13) can be removed

by rotating in an anti-clockwise

direction. If necessary, hold the

outer rim of the honing wheel

(2) to prevent the spindle from

rotating.

2. Remove and discard the

cardboard spacer on the spindle.

Check the spindle is fully to

the left of the sharpener

housing and the small spindle

spacer is fully located on the

spindle and sitting against the

housing bearing.

3. While holding the honing wheel

(13) to prevent the spindle

sliding through the housing,

locate the sharpening wheel (1)

onto the spindle so the wheel

sits against the inner large

washer and spacer.

Note, the spindle must be clean.

4. Still holding the honing wheel, fit

the outer large washer, followed

by the spindle nut, rotating the

nut in a clockwise direction.

Tighten the nut firmly with a spanner, but the

honing

wheel MUST be held

to prevent the main spindle rotating.

Fitting the tool support

and tool holder

1. Loosen the front tool support

clamps (8) and locate the

tool support bar (7) into the

mounting holes on top of the

machine. The tool support

should be orientated with

the rod extending over the

sharpening stone (1).

Note. The top mounting holes of the sharpener should only

be used when utilising the sharpening wheel.

Note. When using the leather honing wheel (2), relocate

the tool support into the mounting holes at the rear of the

machine. The tool support bar must be orientated with the

bar extending over the face of the honing wheel.

2. Slide the adjustable tool holder

(9) onto the rod of the tool

support, as shown. Take care

to orientate the tool holder

as shown opposite; with the

clamping area of the tool

holder (9) towards the centre

Honing

Water reservoir

To install and remove the water

reservoir tray (6) to the side of

the sharpener follow these steps:

1. Hold the tray below the

sharpening stone, and against

the side of the sharpener.

Lift the tray until the locating

hooks of the tray drop into the

corresponding holes in

the housing.

Note. Always check to ensure

the tray is correctly located on the

tabs, and the tray is horizontal.

2. Fill the water reservoir (6)

with water up to the V-shaped

water level indicator.

3. To remove the tray, lift the tray and move the tray away

from the side of the sharpener. When disengaged, lower

the tray from behind the sharpening wheel.

WARNING! Do not sharpen if the sharpening stone is not

resting in water. The sharpening wheel absorbs a lot of

water. You will need to refill the tray as the water is absorbed.

Note. On completion of work empty the water reservoir to

prevent the sharpening stone from being in the water for an

extended period of time.

Note: Clean the tray of dust each

time the tray is emptied.

Using the wetstone sharpener

Note. It is recommended to use in conjunction with this

button (5). Wait for the sharpener to reach full speed

before commencing the job.

2. To turn the sharpener off, press the red “stop” button.

Note. For your safety this tool is fitted with an electro-

magnetic switch. In the event the power supply is

interrupted, the sharpener will turn off, and will not restart

until power is restored and the green “ON” button has been

pressed in again.

Note. This product is designed to operate from a standard

household supply of 230 – 240V AC. Prior to plugging in

the tool, check the rating label tool and ensure that it states

that the operating voltage is 230 – 240V. The machine is

Class 1 Category (earthed) and is fitted with a 3-core cable

and plug. Should the cable or plug be damaged, the product

should be serviced by an authourised Service Centre to

avoid a hazard.

Preparing for sharpening

Setting up for sharpening takes a little practice and

familiarisation with the controls and functions of each

component.

Be patient and practice the set up with various types and

sizes of blades to be sharpened. When setting up the blade

to be sharpened you need to

consider, and set the correct

sharpening angle, and also

ensure the blade to be sharpened

is square across the surface of

the sharpening wheel.

In general, the tool support bar is

positioned on the TOP mounting

points and the sharpening is

performed

against the direction

of rotation.

The following is a guide to assist

with the setting up of the PS120

sharpener.

With the adjustable tool holder

(9) fitted to the tool support bar

as described in the

“Assembly”

section, loosen the tool support

clamps (8) and lower the tool

support until there is approx.

3mm clearance between the

sharpening wheel (1) surface

and the lower guides of the

adjustable tool holder (9).

Note. After setting the height of

the tool support bar (7), tighten

the tool support clamps (8) firmly.

Slide the adjustable tool holder (9) across the surface of the

sharpening wheel (1), ensuring the sharpening wheel (1)

does not touch any part of the adjustable tool holder (9). It is

always advisable to place the adjustable tool holder (9) with

one of the bearing supports directly over the sharpening

wheel (1). Rotate the sharpening wheel (1) by hand one full

revolution to ensure any run out of the wheel does not touch

the tool holder bearing support.

Loosen the two clamps on the adjustable tool holder (9) to

the point where the tool to be sharpened can slide between

the adjustable tool holder (9) and the top clamp.

Slide the blade to be sharpened through the holder until

the blade touches the sharpening wheel (1). Remove any

excess slack in the tool holder

clamp by finger tightening the two

tool holder clamps, BUT ensure

the blade can still slide.

Continue to move the blade through

clamp until the angle between

the wheel and the blade match.

When the angle is correct,

tighten by hand the two clamp

knobs on the tool holder (9)

sufficiently to prevent the blade

moving up or down in the clamp

and thus altering the angle.

Check to ensure the blade is flat

across the sharpening wheel by

touching the wheel across the full

width of the blade. This can be altered by pivoting the blade

on the top side of the clamp assembly from side to side.

When the blade is in the correct position, tighten both of the

clamps knobs on the adjustable tool holder.

Setting up and using the angle gauge

The PS120 has been supplied

with an angle gauge. The angle

gauge is a tool provided to assist

in setting up the correct angle

for the tool to be sharpened

and is an alternative method to

the basic description above for

setting the correct angle.

Set the support bar and

adjustable tool holder as

described above.

Using the angle gauge, insert

the blade edge into the correct

corresponding notch on the side

of the gauge. Either test and

select the angle notch which

corresponds with the blade to

be sharpened or use the guide

label on the face of the gauge to

select the desired angle.

After selecting the required

angle notch, fit the blade to the

tool holder as described above

(to the point where the blade

touched the wheel). Rotate the

clamp knobs on the adjustable

tool holder until the blade is

retained BUT can still slide.

Place the gauge on the wheel

as shown, with the selected

notch directly above the wheel

and closest to the blade to be

sharpened.

Selected notch

3mm

Move the wheel around so the gauge touches the back of

the blade to be sharpened. The angled face of the gauge

should match the back face of the blade. Slide the blade

in or out of the tool holder to obtain a perfect alignment to

the gauge.

When the back of the blade aligns with the gauge, tighten

the adjustable clamp knobs sufficiently to prevent the

blade sliding.

Remove the gauge and check as above the blade is

evenly touching the sharpening wheel across the full

width of the blade.

Tighten the two adjustable clamp knobs.

Sharpening

Using the knife/blade sharpening holder

Your 909 PS120 sharpener

is supplied with a small knife

sharpener holder. This is suitable

for assisting in the sharpening of

small knives and blades.

It takes some time and practice

to master this operation, as it

is partly supported but also has

some free hand components,

where the blade may be curved.

Fitting the knife

to the knife holder

Loosen the two knurled screws

of the knife holder clamp

sufficiently, to slide the knife

between the holder and the top

clamp. The rear screw should

NOT be touching the lower

section of the knife holder

Fit the blade or knife into the holder and tighten the front

knurled screw while holding the top clamp late down flat on

the blade.

Note. Do NOT use any tools to tighten these knurled screws.

The front clamp screw should now be holding the knife

or blade.

Tighten the second (rear knurled screw) to ensure the blade

is firmly clamped for sharpening.

Fit the tool support bar into the sharpening position as

previously described, but the tool support will also need to be

adjusted height wise to obtain the correct sharpening angle.

The knife holder also has an adjustable resting heel which

can also be adjusted up and down to obtain the correct

angle. Set the correct angle for the blade to be sharpened.

Using the adjustable tool holder

Tool sharpening is performed

by working against the direction

of rotation, with the tool support

located on top of the machine.

Note. Ensure safety glasses are

worn during the sharpening and

honing process.

Note. Ensure the water tray is filled with water, and the tray

is correctly fitted prior to starting the sharpening process.

Note. During the sharpening process, frequently check the

water level in the reservoir and constantly top it up.

CAUTION. Do not run the water reservoir dry or attempt to

sharpen dry, it may be dangerous to do so.

Note. Before each operation check whether the surface of

the sharpening stone is even. If required, dress the stone as

described in the maintenance section of this manual.

1. Mount the tool into the tool

holder (9) and fit it to the tool

support bar (7) (refer to the

“Preparing for sharpening

section”

of this manual).

2. Select and set the sharpening

angle (refer to the

“Using the

angle gauge”

section is this

manual).

3. Switch the sharpener on and

press the tool evenly onto

the sharpening stone. Move

the tool sideways across the

stone. Always try and use the

full width of the stone so the

wheel wears evenly.

Note. DO NOT push hard. This

is a sharpening process, not a

grinding process. Light pressure is all that is required.

4. On the completion of the sharpening process, turn off the

sharpener at the on/off switch (5) and remove the plug

from the power point. Proceed to remove, empty and

clean the water tray then remount it as detailed in the

“Assembly” section.

Note. It is not advisable to leave the sharpening wheel

sitting in water when the sharpener is not in use.

Note. New sharpening wheels can show traces of the

production process. You can substantially increase the life

and performance of the wheel by dressing the front face

before use. See the “Maintenance” section.

Honing

Honing is the practice of polishing a cutting edge using a

very fine abrasive such as a lapping paste. It is used after a

sharpening stone to smooth out any irregularities and create

a razor-like finish to the cutting edge.

CAUTION. Never hone against the direction of rotation.

Note. Ensure safety glasses are worn during the sharpening

and honing process.

Honing must only be performed

working with the direction of the

leather wheel. For this reason

the tool support bar needs to be

mounted in the rear mounting

holes prior to honing.

Setting up the honing tool support bar

1. To set up the tool support and the adjustable tool holder

for honing, follow the instructions as per the

“Preparing

for

sharpening” section of this manual except that the

tool support bar (7) must be fitted into the rear mounting

holes instead of the top mounting holes. The bar should

extend out over the honing wheel, and it should be fully

inserted. The bar can be withdrawn later if the angle

requires an outward position, but in most conditions the

bar will need to be fully inserted.

2. Impregnate the leather honing wheel (2) first with a light

machine oil (not supplied) then apply the lapping paste (11).

3. Switch on the machine and use a flat device (ruler, knife

or paint mixing paddle) to distribute the lapping paste

evenly into the leather using circular motion. Repeat this

practice after every 5 to 10 tool sharpenings.

Note. This will increase the life of the leather and the quality

of results.

4. Set the adjustable tool holder as described in

“Preparing

for

sharpening” section. Using the tool holder will

ensure a constant and more even honing process.

Note. To achieve the best result keep the tool mounted in

the tool holder, located in the required angle/position at all

times. DO NOT apply the tool being honed to the honing

wheel without the tool being inserted into the tool holder.

Now that you have correctly set up to hone you can begin

the honing process.

Honing process and technique

When honing NEVER hone against the direction of

the wheel. Press the blade to be honed evenly on to the

honing wheel near the cutting edge and move the blade

across the face of the honing wheel; ensuring that at least

half of the width of the honing wheel is always in contact

with the blade to be honed.

Allow the honing wheel to do the honing for you.

Do not

apply excessive force to the wheel.

Note.

Always keep the honing wheel saturated with

machine oil and abrasion paste.

At the end of the honing process, ensure the sharpener is

switched off at the on/off switch (5) and the plug removed

from the socket.

Maintenance

WARNING. Always ensure that the tool is switched off and

the plug is removed from the power point before making any

adjustments or maintenance procedures.

Dressing the stone

Dressing a stone cleans and levels the front surface to

increase efficiency of operation and prevent vibration.

1. Lower the tool support just above the sharpening stone

and tighten into position. It requires the use of a stone

leveller (not supplied).

2. Start the motor and rest the Stone Leveller onto the tool

support and across the front of the stone, as shown.

Note. Stone levelers have a smooth and a coarse face. For

rapid removal - ie. if the sharpening stone is gouged or quite

uneven, use the coarse face of the leveller. Use the smooth

face for light removal and finishing off the levelling process.

3. Hold the leveller evenly in position until you are satisfied

that the stone is level. It is not necessary to apply

excessive force.

Replacing the sharpening stone

Prior to changing a stone, ensure the tool is switched off

and the power plug is removed from the socket.

1. Unclip the water reservoir (6) from the side of the

sharpener and empty the water from it.

2. Use a spanner to remove the wheel retaining nut by

turning the nut anti-clockwise.

3. Remove the washer and the

old sharpening stone.

4. Ensure the new wheel

conforms to the replacement

wheel specifications.

5. Ensure the clamping surfaces

are clean and fitted with blotters.

6. Fit the wheel on to the spindle and directly against the

inner flange washer.

7. Fit the flange washer against the outer blotter of the

wheel and screw the retaining nut onto the shaft.

8. Tighten the retaining nut

firmly by rotating the spanner

clockwise.

Note. The wheel must be firmly

fixed and to achieve this you

must hold the honing wheel,

NOT the sharpening wheel when

tightening the nut.

CAUTION. Do not over tighten

as this can damage the stone.

9. Clip the water reservoir onto the side of the sharpener.

Lubrication

1. This tool uses pre-lubricated sealed ball bearings for the

motor and does not require lubrication.

2. Lubrication of the drive shaft should be checked after each

50 hours of operation by an authorised service centre.

Power cord maintenance

If the supply cord needs replacing, the task must be carried

out by the manufacturer, the manufacturer’s agent, or an

authorised service centre in order to avoid a safety hazard.

Cleaning

1. Keep the outside of the sharpener clean by brushing

sharpening dust and dirt away from all areas where the

dust tends to build up.

2. Regularly wipe down the sharpener with a soft damp

cloth. A mild detergent can also be used.

Never use caustic agents, petrol based cleaners,

alcohol or any other cleaning agents. Do not wet down

the sharpener.

CAUTION. Do not use cleaning agents to clean the

plastic parts of the tool. A mild detergent on a damp

cloth is recommended.

General inspection

Regularly check that all the fixing screws are tight.

They may vibrate loose over time.
