OPERATION

Fig.13
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 surface, 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 thick, cut at about 250 mm/min. When cutting tile
10 mm thick, cut at about 300 mm/min.) Also slow down
as you complete 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.

MAINTENANCE

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