READ ALL INSTRUCTIONS

BEFORE USING THIS APPLIANCE

INSTRUCTIONS PERTAINING TO A RISK OF INJURY

GENERAL

A. GROUNDING INSTRUCTIONS

1. All grounded, cord-connected tools:

In the event of a malfunction or breakdown,

grounding provides a path of least resistance for

electric current to reduce the risk of electric shock.

This tool is equipped with an electric cord having an

equipment-grounding conductor and a grounding

plug. The plug must be plugged into a matching outlet

that is properly installed and grounded in accordance

with all local codes and ordinances.

Do not modify the plug provided – if it will not ﬁt the

outlet, have the proper outlet installed by a qualiﬁed

electrician.

Improper connection of the equipment-grounding

conductor can result in a risk of electric shock.

The conductor with insulation having an outer

surface that is green with or without yellow stripes

is the equipment-grounding conductor. If repair or

replacement of the electric cord or plug is necessary,

do not connect the equipment-grounding conductor to

a live terminal.

Check with a qualiﬁed electrician or service personnel

if the grounding instructions are not completely

understood, or if in doubt as to whether the tool is

properly grounded.

Use only 3-wire extension cords that have 3-prong

grounding plugs and 3-pole receptacles that accept

the tool’s plug.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on a

supply circuit having a nominal rating less than 150V:

This tool is intended for use on a circuit that has an

outlet that looks like the one illustrated in Sketch

A in Figure 1. The tool has a grounding plug that

6

BENCH GRINDER ENG

looks like the plug illustrated in Sketch A in Figure

1. A temporary adapter, which looks like the adapter

illustrated in Sketches B and C, may be used to

connect this plug to a 2-pole receptacle as shown

in Sketch B if a properly grounded outlet is not

available. The temporary adapter should be used only

until a properly grounded outlet can be installed by

a qualiﬁed electrician. The green-colored rigid ear,

lug and the like, extending from the adapter must be

connected to a permanent ground such as a properly

grounded outlet box.

3. Grounded, cord-connected tools intended for use on

a supply circuit having a nominal rating between 150-

250V, inclusive:

This tool is intended for use on a circuit that has an

outlet that looks like the one illustrated in Sketch D in

Figure 1. The tool has a grounding plug that looks like

the plug illustrated in Sketch D in Figure 1. Make sure

the tool is connected to an outlet having the same

conﬁguration as the plug. No adapter is available

or should be used with this tool. If the tool must be

reconnected for use on a different type of electric

circuit, the reconnection should be made by qualiﬁed

service personnel; and after reconnection, the tool

should comply with all local codes and ordinances.

4. Permanently connected tools:

This tool should be connected to a grounded metal

permanent wiring system; or to a system having an

equipment-grounding conductor.

B. FOR ALL DOUBLE-INSULATED TOOLS

1. Replacement parts

When servicing use only identical replacement parts.

2. Polarized Plugs

To reduce the risk of electric shock, this equipment

has a polarized plug (one blade is wider than the

other). This plug will ﬁt in a polarized outlet only one

way. If the plug does not ﬁt fully in the outlet, reverse

the plug. If it still does not ﬁt, contact a qualiﬁed

electrician to install the proper outlet. Do not change

the plug in any way.

C. FOR ALL TOOLS AS APPLICABLE

1. KEEP GUARDS IN PLACE and in working order.

2. REMOVE ADJUSTING KEYS AND WRENCHES. Form

habit of checking to see that keys and adjusting

wrenches are removed from tool before turning it on.

3. KEEP WORK AREA CLEAN. Cluttered areas and

benches invite accidents.

4. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t

use power tools in damp or wet locations, or expose

them to rain. Keep work area well lighted.

5. KEEP CHILDREN AWAY. All visitors should be kept

safe distance from work area.

6. MAKE WORKSHOP KID PROOF with padlocks, master

switches, or by removing starter keys.

7. DON’T FORCE TOOL. It will do the job better and safer

at the rate for which it was designed.

8. USE RIGHT TOOL. Don’t force tool or attachment to

do a job for which it was not designed.

9. USE PROPER EXTENSION CORD. Make sure your

extension cord is in good condition. When using an

extension cord, be sure to use one heavy enough

to carry the current your product will draw. An

undersized cord will cause a drop in line voltage

resulting in loss of power and overheating. Table 1

shows the correct size to use depending on cord

length and nameplate ampere rating. If in doubt, use

the next heavier gage. The smaller the gage number,

the heavier the cord.

10. WEAR PROPER APPAREL. Do not wear loose clothing,

gloves, neckties, rings, bracelets, or other jewelry

which may get caught in moving parts. Nonslip

footwear is recommended. Wear protective hair

covering to contain long hair.

11. ALWAYS USE SAFETY GLASSES. Also use face or

dust mask if cutting operation is dusty. Everyday

eyeglasses only have impact resistant lenses, they

are NOT safety glasses.

12. SECURE WORK. Use clamps or a vise to hold work

when practical. It’s safer than using your hand and it

frees both hands to operate tool.

13. DON’T OVERREACH. Keep proper footing and balance

at all times.

14. MAINTAIN TOOLS WITH CARE. Keep tools sharp

and clean for best and safest performance. Follow

instructions for lubricating and changing accessories.

15. DISCONNECT TOOLS before servicing; when

changing accessories, such as blades, bits, cutters,

and the like.

16. REDUCE THE RISK OF UNINTENTIONAL STARTING.

Make sure switch is in off position before plugging in.

17. USE RECOMMENDED ACCESSORIES. Consult the

owner’s manual for recommended accessories. The

use of improper accessories may cause risk of injury

to persons.

18. NEVER STAND ON TOOL. Serious injury could occur if

the tool is tipped or if the cutting tool is unintentionally

contacted.

19. CHECK DAMAGED PARTS. Before further use of the

7

BENCH GRINDER ENG

tool, a guard or other part that is damaged should

be carefully checked to determine that it will operate

properly and perform its intended function – check

for alignment of moving parts, binding of moving

parts, breakage of parts, mounting, and any other

conditions that may affect its operation. A guard

or other part that is damaged should be properly

repaired or replaced.

20. DIRECTION OF FEED. Feed work into a blade or cutter

against the direction of rotation of the blade or cutter

only.

21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN

POWER OFF. Don’t leave tool until it comes to a

complete stop.

ASSEMBLY

NOTE:

Before using the tool, read the instruction

book carefully.

CAUTION! During use, it is important not to

overload the grinder. The grinder should run

at close to full speed. If you are applying too much

pressure, the grinder will start to slow down. Under these

conditions, remove the part being ground and allow the

grinder to return to full speed. Re-apply the part to the

grinder, but with a little less force.

All of the grinders are supplied with grinding discs

designed for metal use only. The grinding of Copper,

Brass, Aluminum, Wood or other similar materials will

“clog” the grinding disc.

IMPORTANT: Remove the power plug from

the electrical socket before carrying out any

adjustment, servicing or maintenance.

1. FITTING AND ADJUSTING THE SPARK ARRESTERS

(SEE FIG.A)

Insert a screw (a) through the spark arrester slot and ﬁx

onto the wheel guard with a screwdriver (not supplied).

To adjust the spark arrester, loosen the screw and slide

the deﬂector up or down. Make sure that the bottom edge

is less than 5/64”(2mm) from the surface of the disc, but

not touching the disc.

Rotate the disc by hand one full rotation to ensure the

disc can rotate without contacting the spark arrester.

Firmly tighten the screw retaining the spark arrester.

2. FITTING AND ADJUSTING THE EYE SHIELDS

(SEE FIG.B, C, D)

NOTE: Always ensure the eye shields are correctly ﬁtted

before the grinder is used. Eye shields must be ﬁtted over

each grinding disc on all bench grinders.

Install the eye shield as shown in Fig.B & C.

Remove both eye shields from packaging, attach the

shields onto the two mounting brackets. Fix and tighten

the mounting brackets ﬁrmly to the screw holes on the

inner guard. Make sure the eye shields are securely

mounted, and positioned to deﬂect debris coming from

the wheel.

NOTE: The Magniﬁer eye shield features a magnifying

glass incorporated into the design to provide greater

visibility and improved accuracy.(SEE FIG.D)

3. FITTING THE WORK RESTS (SEE FIG.E, F)

The work rests are required for each high speed grinding

disc to assist in grinding operation.

CAUTION: Never use a bench grinder on which

the work rest has not been ﬁtted or where the

work rest has not been correctly adjusted.

NOTE: The work rests are right and left-handed. Follow

the diagrams to ensure the work rest is ﬁtted to the

correct side.

1) Hold the work rest in the correct position against the

inner surface of the wheel guard. Fit the securing screws

(b) through the work rest and the guard.

2) Tighten the securing knob (5) sufﬁciently to support

the work rest but still allowing the work rest to slide

inwards and outwards.

3) Slide the work rest with a maximum distance of 5/64”

(2mm) from the disc. Rotate the disc one full revolution by

hand to ensure the disc does not contact the work rest.

4) Tighten the securing knob (5) ﬁrmly to retain the

assembly. Repeat the assembly operation for the other

work rest.

4. MOUNTING THE GRINDER

The base of the grinder has two holes on both sides.

These holes accept bolts (not supplied) less than 3/8”

(10mm) in diameter. Mounting the grinder to a solid level

surface is recommended.

Where the grinder is to be mounted to a steel work bench

(not supplied), it is advisable to place a piece of wood

between the bench and grinder then bolt through the

grinder and timber into the bench. This further assists to

reduce vibration.

IMPORTANT:

When directly mounting the grinder ensure the surface

under the grinder is ﬂat and clean.

OPERATING INSTRUCTIONS

IMPORTANT:

Ensure that the eye shields, spark arresters, and the work

rests are ﬁtted and correctly adjusted and that you are

wearing safety gear including eye, hearing and breathing

protection before using the tool.

WARNING: Never attempt to grind Magnesium.

Only use the front face of the grinding disc but

not the sides. Please note that the work piece can get

very warm. It may be necessary to cool a work piece by

dipping it in a coolant or in water. Do not apply coolant or

water to the grinding disc.

- Turn the disc by hand to make sure it does not touch

the guard, eye shields, spark arresters or work rests and

runs freely.

- Stand to one side, turn the switch on and allow the

motor to reach full speed.

- Support the work piece on the work rest and gradually

feed the work piece onto the disc.

NOTE: Traverse the work piece across the full width of

the disc to prolong its ﬂat surface.

- If the grinding operation causes the motor speed to

noticeably decrease, pull back the work piece, allow

the motor to regain full speed and restart the grinding

operation, but apply less force.

1. ON/OFF SWITCH (SEE FIG.G)

To turn the grinder on, press the On/Off switch to the

position marked “ON”.

To turn the grinder off, press the On/Off switch to the

position marked “Off”.

2. CHANGING A GRINDING DISC (SEE FIG.H, I)

IMPORTANT:

Remove the power plug from the electrical socket

before changing a disc.

1) Remove the retaining screw and take off the tool rest.

2) Remove the retaining screw and take off the spark

deﬂector.

3) Take off the three retaining screws and remove the

outer guard.

4) Use the wrench to ﬁx one side nut, rotate the wrench

to release the other side nut at the same time. Then

remove the retaining nut, outer ﬂange and the wheel.

NOTE: The wheel on the left-hand side of the grinder

has a left-hand thread and is unscrewed in a clockwise

direction. The wheel on the right-hand side of the grinder

has a right-hand thread and is unscrewed in an anti-

clockwise direction.

5) Fit the replacement wheel on the shaft ensuring that

there is a blotter between the wheel and clamp washers

on each side of the wheel, and ensure the wheel is a slide

ﬁt (not loose) on the spindle.

6) Replace the outer ﬂange and retaining nut (see the

Note above regarding the direction of rotation of the nut).

10

BENCH GRINDER ENG

7) Tighten the nut. Do not over tighten.

8) Replace the outer guard.

9) Replace the retaining screw, spark deﬂector and tool

rest.

10) Re-adjust the tool rest and spark deﬂector.

11) Rotate the wheel by hand to check for free movement

and proper adjustments.

12) Plug in the grinder, put on eye protection, stand to one

side and run the grinder at full speed for several minutes.

MAINTENANCE

Remove the power plug from the electrical socket

before carrying out any adjustment, servicing or

maintenance.

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.

GRINDER ADJUSTMENTS

During the life of the grinder, some adjustments are

required to maintain a safe working environment. Please

ensure the following:

•Alwaysadjusttheeyeshieldstothemostcomfortable

and most effective angle to suit the task being performed.

•Asthewheelswear,thesparkarrestersmustbe

adjusted to ensure that the distance from its bottom edge

to the wheel surface is not more than 5/64” (2mm).

•Asthewheelswear,theworkrestsmustalsobe

adjusted to make sure that the distance is not more that

5/64”(2mm) from its edge to the wheel surface.

LUBRICATION

1. All models use pre-lubricated sealed ball bearings for

the motor and do not require lubrication.

2. If the discs do not rotate freely, the bearings should be

replaced by an authorized service center.

CLEANING

1. Keep the outside of the grinder clean by brushing

grinding dust and dirt away from all areas where the dust

tends to build up. Wear eye protection when brushing.

2. Wipe the guards and grinder with a soft damp cloth. A

mild detergent can also be used.

3. Wipe the eye shields with a soft damp cloth, making

sure not to scratch the surface. A mild detergent can also

be used.

CAUTION: Never use caustic agents, petrol based

cleaners, alcohol or any other cleaning agents. Do

not wet down the grinder.

GENERAL INSPECTION

Regularly check that all the ﬁxing screws are tight. They

may vibrate loose over time.

TROUBLESHOOTING

Although your new bench grinder is really very simple

to operate, if you do experience problems, check the

following:

1. GRINDER WILL NOT START

Check that there is electrical power at the socket; test

with an electrical screwdriver or another electrical

appliance; check the connections in the plug; correct

and tighten poor connections; check the fuse; if suspect

replace with correct rating.

2. WHEEL WOBBLES OR VIBRATES

Check that the lock-nut is tight. Check that the wheel

is correctly located on the shaft and locating washer.

If excessive pressure has been used or the wheel has

“caught”, it may be damaged enough to vibrate. DO NOT

USE if there is any evidence that the wheel is damaged.

Remove it and replace with a new wheel. Dispose of old

wheels sensibly.

3. WHEEL LEAVES ROUGH FINISH.

Too much pressure on the wheel can cause a poor

surface ﬁnish. If working with aluminum or similar soft

alloy, the wheel will soon become clogged and will not

grind effectively.

There are no other user serviceable parts in your

bench grinder.
