9. USE PROTECTIVE EQUIPMENT. Use

safety glasses. Use face or dust mask if

cutting operations create dust.

10. CONNECT DUST EXTRACTION

EQUIPMENT. If devices are provided

for the connection of dust extraction

and collecting equipment, ensure these

are connected and properly used.

11. DO NOT ABUSE THE CABLE. Never

pull the cable to disconnect it from the

socket. Keep the cord away from heat,

oil and sharp edge.

12. SECURE WORK. Where possible use

clamps or a vice to hold the work. It’s

safer than using your hand.

13. DON’T OVERREACH. Keep proper

footing and balance at all time.

14. MAINTAIN TOOLS WITH CARE.

Keep cutting tools sharp and clean

for better and safer performance.

Follow instructions for lubricating and

changing accessories. Inspect tool

cords periodically and if damaged

have them repaired by an authorized

service facility. Inspect extension cords

periodically and replace if damaged,

keep handles dry, clean and free from

oil and grease.

15. DISCONNECT TOOLS. When not

in use, before servicing and when

changing accessories such as blades,

bits, cutters, disconnect tools from the

power supply.

16. REMOVE ADJUSTING KEYS AND

WRENCHES. Form the habit of

checking to see that keys and adjusting

wrenches are removed from the tool

before turning it on.

17. AVOID UNINTENTIONAL STARTING.

Ensure switch is in “off” position when

plugging in.

18. USE OUTDOOR EXTENSION LEADS.

When the tool is used outdoors, use

only extension leads intended for

outdoor use and so marked.

General Safety Rules

Read all these instructions before

attempting to operate your product.

Save these instructions for future

reference.

1. KEEP WORK AREA CLEAR. Cluttered

areas and benches invite injuries.

2. CONSIDER WORK AREA

ENVIRONMENT. Do not expose tools

to rain. Do not use tools in damp or

wet locations. Keep work area well lit.

Do not use tools in the presence of

ammable liquids or gases.

3. GUARD AGAINST ELECTRIC SHOCK.

Avoid body contact with earthed or

grounded surfaces.

4. KEEP OTHER PEOPLE AWAY. Do

not let others, especially children, not

involved in the work touch the tool or

the extension lead and keep them away

from the work area.

5. STORE IDLE TOOLS. When not in use,

tools should be stored in a dry locked-up

place, out of reach of children.

6. DO NOT FORCE THE TOOL. It will do

the job better and safer at the rate for

which it was intended.

7. USE THE RIGHT TOOL. Do not force

small tools to do the job of a heavy

duty tool. Do not use tools for purposes

not intended; for example do not use

circular saws to cut tree limbs or logs.

8. DRESS PROPERLY. Do not wear loose

clothing or jewellery, they can be caught

in moving parts. Nonskid footwear is

recommended when working outdoors.

Wear protective hair covering to contain

long hair.

WARNING! When using electric tools

basic safety precautions should always

be followed to reduce the risk of re,

electric shock and personal injury.

26. USE CORRECTLY SHARPENED

SAW BLADES. Observe the maximum

speed marked on the saw blade.

Ensure that the machine is always xed

to a bench, whenever possible.

Additional Safety Rules

for Marble Cutter

1. Do not use grinding wheel.

Use only diamond blades recommended

by the manufacturer.

Do not use damaged or deformed blades.

4. Never operate the product without the

blade cover.

5. Never turn on the product when the

blade touches the workpiece.

6. Never put down the marble cutter until

the blade stops completely.

7. Do not force the blade to stop.

8. To prevent injury, be sure to unplug

from the power source outlet before

assembling, adjusting, or maintaining

the marble cutter.

9. Residual Current Device (RCD) is

recommended to be used. If in any

doubt consult a qualied electrician.

10. Do not operate the product in line with

the blade.

11.

Avoid kickback when operating the product

on the wall or doing a blind cutting.

12.

Hold the marble cutter rmly during oper-

ating.

Do not reach to the section below the

blade where there is no cover to

protect you.

13. Do be sure that the diamond blade is

mounted on a correct diameter blade

shaft between proper blades collars

and is securely hand-tightened with

wrenches. If not in proper size, serious

injury might happen.

WARNING! For your own safety, read all

these instructions before attempting to

operate your product.

19. STAY ALERT. Watch what you are

doing, use common sense and do not

operate the tool when you are tired.

20. CHECK DAMAGED PARTS. Before

further use of the tool, it should be

carefully checked to determine that it

will operate properly and perform its

intended function. Check the 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 by an authorized service

centre unless otherwise indicated in

this instruction manual. Do not use the

tool if the switch does not turn it on and

THE ELECTRICAL MAINS, shortly

voltage drops can appear when

starting the EQUIPMENT. This can

inuence other equipment (e.g. blinking

of a lamp). If the MAINS-IMPEDANCE

Zmax < 0.34 OHM, such disturbances

are not expected.

24. DO NOT USE SAW BLADES

MANUFACTURED FROM HIGH

SPEED STEEL.

25. KEEP THE FLOOR AREA AROUND

THE MACHIN LEVEL, well maintained

and free of loose material e.g. chips

and cutoffs.

14. To avoid injury, if the power cable is

damaged, do not change by yourself.

Please contact a qualied engineering

or local manufacturer to deal with.

ENVIRONMENTAL PROTECTION

Recycle unwanted materials instead

of disposing of them as waste.

All tools, hoses and packaging

should be sorted, taken to the local

recycling center and disposed of in an

environmentally safe way. Do not dispose of

electrical appliances as unsorted municipal

waste, use separate collection facilities.

Contact your local government for

information regarding the collection systems

available. If electrical appliances are

disposed of in landlls or dumps, hazardous

substances can leak into the groundwater

and get into the food chain, damaging your

health and well-being. When replacing

old appliances with new once, the retailer

is legally obligated to take back your old

appliance for disposal at least for free of

charge. Disposal of discarded material shall

be in accordance with local environmental

regulations.

Keep hands away from blade:

away from the blade will result in

serious personal injury.

WARNING! To reduce the risk of

injury, user must read instruction

manual.

Wear safety goggles.

Wear ear protection.

Wear a breathing mask.

Setting the Tool

WARNING! To avoid injury from an

accidental start, ALWAYS make sure

the switch is in the “OFF” position,

and the plug is not connected to the

power source outlet before making any

adjustments.

Connecting to the Power Supply

Check that the power supply and outlet

used is in accordance with your marble

cutter. Have a look at the rating plate of the

motor, if any changes should always be

carried out by a qualied electrician.

USING AN EXTENSION LEAD

The use of any extension lead will cause

some loss of power. To keep this to a

minimum and to prevent overheating and

motor burn-out, ask advice from a qualied

electrician to determine the minimum wire

size of the extension lead. If the power

cable is broken, repair service is available

at your nearest service center.

WARNING! Avoid contact with the

terminals on the plug when installing

(removing) the plug to (from) the power

supply outlet. Contact will cause a

severe electrical shock.

Operating the Tool

WARNING!

●

Never connect the plug to the power

source outlet until all installations and

adjustments are completed and you

have read and understood the safety

and operation instructions.

●

Be sure to move the marble cutter

forward in a straight line.

full speed.

4. Hold the machine rmly and move

forward in alignment with the cutting line.

WARNING! Forcing and applying

excessive pressure might allow the

blade to bend. Pinch or twist in the cut

can cause overheating of the motor and

dangerous kickback of the tool.

WET CUT
