MAINTENANCE
 Tighten brush cap securely. Do not overtighten.
CLEANING THE RAILS
During use, the rails will become dirty preventing the table
rollers from sliding smoothly. It is important to clean the rails
often. Lubricate with light oil (e.g., WD40).
CLEANING THE SAW
See Figure 47.
 Unplug the saw and water pump.
 Empty the dirty water from the water tank and replace
with clean water.
 Store the water tank on the center brace and place the
submersible pump in the tank.
 Place the pump switch in the B position (see figure 26).
 With the diverter valve turned to the left, run the clean
water through the saw flushing debris through the tubes
and over the cutting wheel.
 Turn the diverter valve to the right. Using the cleaning
nozzle, rinse off the sliding table.
 Unlock table stop (turning until the slot is vertical).
 Grasp the table firmly before pulling the table to the front
and off the tool.
 Once the table has been removed, rinse the rails and
water tray, water tray frame, and bevel feature. Lubricate
with light oil (e.g., WD40).
 Replace the drain plug. Tighten securely.
 Empty dirty water from the water tank and dry off the
tool.
CLEANING THE SUBMERSIBLE PUMP
 Unplug pump before handling or cleaning the pump.
 Remove the front cover.
 Using a small brush and/or water, clean any debris or
trash that is trapped on the inside of the pump.
NOTE: To maintain efficiency and extend the life of the
pump, check intake screen before use to make sure it is
clean.
 Rinse filter with clean water
If the pump will not run, try the following solutions:
 Ensure that the intake screen is free of obstructions.
 Make sure that the water hose isn't clogged or knotted.
 Be sure the unit is plugged into a functioning power outlet
and the pump is plugged into the electrical plug.
 Be sure there is adequate water in the water tank and that
the pump switch and variable flow valve are both turned
on.
NOTE: Do not handle the pump while it is connected to a
power source.
