Adjust the amount of water flow. Hold the tool firmly. Set the base plate on the
003545
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 for-
ward 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.
CAUTION:
• Always be sure that the tool is switched off and unplugged before
attempting to perform inspection or maintenance.
Dressing diamond wheel
If the cutting action of the diamond wheel begins to diminish, use an old dis-
carded coarse grit bench grinder wheel or concrete block to dress the diamond
wheel. To do this, tightly secure the bench grinder wheel or concrete block and
cut in it.
After use
Blow away dust from the inside of the tool by running the tool at an idle for a
while. Brush off accumulation of dust on the base. Accumulation of dust in the
motor or on the base may cause a malfunction of the tool.
Cleaning covers
003543
When accumulation of dust on the cover (A) looks excessive, loosen the
clamp and remove the cover (A). Wash off accumulation of dust inside the
cover (A) and wipe it. Then install the cover (A) on the tool so that its side with
"Upside " mark faces upward. Push the cover (A) toward the motor as far as
it will go and secure it by tightening the clamp.
