Adjust the amount of water flow. Hold the tool firmly. Set
the base plate on the workpiece to be cut without the
wheel making any contact. Then turn the tool on and
wait until the wheel attains full speed. Now simply move
the tool forward over the workpiece surface, keeping it
flat and advancing smoothly until the cutting is
completed. Keep your cutting line straight and your
speed of advance uniform.
CAUTION:
THIS TOOL SHOULD ONLY BE USED ON
•
HORIZONTAL SURFACES.
Be sure to move the tool forward in a straight line
•
and gently. Forcing and exerting excessive
pressure or allowing the wheel to bend, pinch or
twist in the cut can cause overheating of the motor
and dangerous kickback of the tool.
Since excessive cutting may cause overload of the
•
motor, the depth of cut should not be more than 20
mm at a pass. When you wish to cut more than 20
mm deep, make a couple of passes with
progressively deeper settings.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
•
unplugged before attempting to perform inspection
or maintenance.
