OPERATION

► Fig.9
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 com-
pleted. 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.

• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
