OPERATION
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. Feed water
to the wheel by adjusting the water cock to obtain a gentle
flow of water. Move the tool forward over the workpiece sur-
face, keeping it flat and advancing smoothly until the cutting
is completed. Keep your cutting line straight and your speed
of advance uniform.
For fine, clean cuts, cut slowly. (When cutting glass plate
5 mm (3/16) thick, cut at about 250 mm/min (9-7/8/min).
When cutting tile 10 mm (3/8) thick, cut at about
300 mm/min (11-13/16/min).) Also slow down as you com-
plete a cut to avoid breaking or cracking the workpiece being
cut.
CAUTION:
Be sure to hold the workpiece firmly down on a stable
bench or table during operation.
Do not twist or force the tool in the cut, or the motor may
be overloaded or the workpiece may break.
Do not use the tool with the wheel in an upward or
sideways position.
When cutting glass plate, it is recommended to attach a
rubber plate (optional accessory) on the base of the tool
to prevent the workpiece surface from being scratched.
The wheel for this tool is a wet-type wheel for glass and
tile applications. Be sure to feed water to the wheel
during operation.
If the cutting action of the wheel begins to diminish,
dress the cutting edge of the wheel using an old
discarded coarse grit bench grinder wheel or concrete
block. Dress by pressing lightly on the outer edge of the
wheel.
NOTE:
If the tool is operated continuously until the battery
cartridge has discharged, allow the tool to rest for 15
minutes before proceeding with a fresh battery.
