GROUND FAULT CIRCUIT INTERRUPTER
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 defec-
tive 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!
1. The GFCI is a safety device, do not use as an off/on switch.
2. The GFCI on the tool will not protect you if you cut into another current carrying
conductor.
3. Do not use where water may enter GFCI case.
4. Do not modify or allow GFCI to be immersed in water.
A Ground Fault Circuit Interrupter (GFCI) is mounted at the end of a power supply cord.
The GFCI goes OFF when water enters inside the tool’s housing to prevent 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.

motor will burnout. Any attempts to do so may damage the tool and/or cause an
accident.
2. Make sure the ON/OFF switch is off.
– If you plug in the power supply cord without realizing that the switch is ON, the
machine will start and may cause an accident.
– Make sure the switch is in the OFF position before plugging the cord in the power
outlet.
3. Inspect the protective cover.
– Do not remove the cover. It will protect you if the saw blade breaks.
– Be sure to rmly attach the saw blade or any optional accessory.
4. Inspect the saw blade.
– Check if you have a specied blade.
– Never use cracked, chipped, or any damaged blades.
– Follow the procedures specied in the instruction manual to properly attach
applicable accessories.

5. Check the power outlet.
– When the plug of the power supply cord is easily pulled out of the power outlet,
the outlet should be replaced. For such tasks, consult an electrician. If the power
outlet is used on a continuous basis, it may overheat and cause accidents.
6. Perform test runs.
WARNING!
1. Before turning the switch ON, make sure the rotating parts are not touching
anything. If the switch is turned ON while they are in contact with anything
else, the blade may get damaged and it may cause injuries.
2. When a new blade is attached and the switch is turned ON, keep your body
well away from the exposed sides of the tool for a moment until the machine
reaches its full speed.
3. It is very dangerous to perform cutting operations using cracked, chipped or damaged
blades. Before starting cutting operations, keep the tool away from anyone nearby. Be
sure to perform a few test runs to check whether there are any abnormalities.
ABOUT DOUBLE INSULATION
This machine is designed with double insulation. Two insulations are used between the
conductor and the outer body of the machine. An Electric Machine with the double insulation
highly improves safety from electric shocks. Do not attach or replace unspecied parts and
do not assemble incorrectly. This may cause the insulation to malfunction.

CAUTION!
Allow the saw blade to do the work, applying excessive forward pressure to the tool will
slow down the RPM’s and burn up the motor, which voids the limited warranty of the tool.
This tool should only be used for cutting on a horizontal surface. Be sure to follow daily
maintenance before and after each use.
OPTION 1: FREE-HAND CUTTING
If you are cutting stone or tile less than 20mm (3/4”) thick, the cut can be done in one
pass (allow saw blade to do the work).
1. If you are cutting stone or tile more than 20mm (3/4”) thick you will need to make the
cut in two passes. Adjust the height to 15-20mm for the rst pass, then adjust the
saw blade below the stone for the second pass (allow the saw blade to do the work).
2. Adjust the amount of water ow to cool the blade and remove the waste, (excessive
water ow will get inside the tool and trip the GFCI).
3. Set the base plate on the workpiece and align to the cutting mark on the base plate
to cut line on the stone.
4. Press the on/off switch to start the motor and allow the tool to attain full speed before
starting to cut.
5. Advance the tool slowly allowing the blade to do the work, keeping the base plate at
on the stone and the cut mark in line with your cut line.
6. Slow the cutting speed for the last 1/2” to prevent the tile or stone from chipping.
OPTION 2: USING THE TT RULER GUIDE
Install the ruler on the ESC-125 by inserting the arms into the appropriate
slots on the base plate and tightening the screws to secure the ruler in place.
1. When using the edge of the stone as your guide,
install the ruler so that it is below the base plate
(Figure-21). Measure the distance from the
edge to the intended cut and use this measure-
ment to set the ruler at the proper distance.
2. When using a straight edge as a guide, install the
ruler so that it is above the base plate (Figure-22).
Measure the distance from the straight edge to the
intended cut and use it to set the ruler at the proper
distance. When cutting, simply keep the ruler in
contact with the straight edge while maintaining
even cutting pressure and the cuts will be straight.

OPTION 3: USING THE CARRIAGE ASSEMBLY AND GUIDE
RAIL (WET OR DRY)
Note: Refer to OSHA Standard 1926.1153 - Respirable Crystalline Silica for Specied
Exposure Control Methods.
CURVE CUTTING APPLICATION
When cutting the curved line, remove the TT ruler guide and cut free-hand.
Step 1. Score along the cutting line (1/3 width of stone).
Step 2. Step-cut along scored line (2/3 width of stone).
Step 3. Plunge cut all the way to make full contact between bottom plate and stone, then
maintain even cutting pressure to follow curved cut line.
