the adapter on the vinyl tube to a faucet of water mains
pressure. Adjust the amount of water flow by simply
adjusting the water cock.
CAUTION:
• When adjusting depth of cut, also adjust the
position of water pipe. Otherwise, the diamond
wheel may damage the water pipe or the dia-
mond when it does not receive proper water
flow.
OPERATION
► Fig.7
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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspec-
tion or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
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.
Replacing carbon brushes
