For Safe Operation
1. Keep work area clean
Cluttered areas and benches invite injuries.
2. Consider work area environment
Do not expose power tools to rain. Do not use power tools in damp or wet locations
without GFCI protection. Keep work areas well lit. Do not use the tool in presence of
flammable liquids or gases.
3. Guard against electric shock
Prevent body contact with grounded surfaces. For example: pipes, radiators, ranges,
and refrigerator enclosures; use grounded outlets.
4. Keep children and visitors away
Do not let visitors contact tool or extension cord. All visitors should be kept away from
work area. Keep out of reach of children.
5. Tool Storage
When not in use, tools should be stored in a secure dry location. A locked storage area
or high shelf out of children’s reach is ideal.
6. Do not force the tool
It will do the job better and be safer at the rate for which it was intended.
7. Use the right tool
Do not force a small tool or attachment to do the job of a heavy-duty tool. Do not use
the tool for purposes it is not designed for – (for example – do not use stone cutter for
cutting tree limbs or logs.)
8. Dress properly
Do not wear loose clothing or jewelry. Items such as these can be caught in moving
parts. Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protective hair covering to contain long hair.
9. Use safety equipment

13. Maintain tools with care
Keep tools sharp and clean for better and safer performance. Follow instructions for
lubricating and changing accessories. Inspect the electrical cord periodically and
if damaged, have it repaired by authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean and free from oil and
grease.
14. Disconnect tools
Disconnect the tool from the power supply when not in use, before servicing, and when
changing accessories, such as blades, bits, cutters.
15. Remove adjusting keys and wrenches

GROUND FAULT CIRCUIT INTERRUPTER:
DANGER!
Do not bypass the GFCI if this condition occurs, a real shock hazard may exist.
WARNING!
If the GFCI fails to trip when the test button is pressed, or fails to reset, the device is
defective and should be replaced.
If the GFCI tests properly without a load applied, but trips each time a load is connected,
then the load (tool) has a ground fault condition and needs to be repaired or replaced.
Do not bypass the GFCI if this condition occurs, a real shock hazard may exist.
CAUTION!
The GFCI is a safety device, do not use as an off/on switch.
The GFCI on the tool will not protect you if you cut into another current carrying
conductor.
Do not use where water may enter GFCI case.
Do not modify or allow GFCI to be immersed in water.
AGround Fault Circuit Interrupter (GFCI) is mounted at the end of power supply cord.
The GFCI goes OFF when water enters inside the tool’s housing preventing the operator
from receiving electric shocks.
When the GFCI goes OFF, the Reset button pops up.
This is the result of water entering the stone cutter
housing.
Turn OFF the power switch and blow dry air inside the
motor cover through the air vents.
Press the GFCI Reset button. The stone cutter is
ready to start working after the reset button is pressed
down.
1. Do not remove the GFCI.
