Water supply (Fig. 15)
Remove the cap on the tank and fill through the hole. Recap the tank. Be sure that the water cock is turned off when filling the tank with water.
CAUTION:
When filling the tank with water, be careful not to let the machine get wet.
Operation (Fig. 16)
Hold the machine firmly. Set the base plate on the workpiece to be cut without the wheel making any contact. Then turn the machine 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 machine 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 machine in the cut, or the motor may be overloaded or the workpiece may break.
·Do not use the machine 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 machine to prevent the workpiece surface from being scratched.
·The wheel for Model 4190D/DB is a
·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 con- crete block. Dress by pressing lightly on the outer edge of the wheel.

CAUTION:
If the machine is operated continuously until the battery cartridge has discharged, allow the machine to rest for 15 minutes before proceeding with a fresh battery.
MAINTENANCE
CAUTION:
Always be sure that the machine is switched off and the battery cartridge is removed before carrying out any work on the machine.
