MAINTENANCE
LUBRICATION
All of the bearings in this tool are lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. After extended use, clean the
rails so the table will slide smoothly.
BRUSH REPLACEMENT
See Figure 35.
The saw has externally accessible brush assemblies that
should be periodically checked for wear.
Proceed as follows when replacement is required:

Unplug the saw.

Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush
cap.

Remove brush assembly.

Check for wear. Replace both brushes when either has
less than 1/4 in. length of carbon remaining. Do not
replace one side without replacing the other.

Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.

Make sure brush cap is oriented correctly (straight) and
replace.
 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.
CLEANING THE SAW

Unplug the saw and plug in 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).

Run the clean water through the saw flushing debris
through the tubes and over the cutting wheel.

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, and water tray frame.

Replace the drain plug. Tighten securely.

Empty dirty water from the water tank and dry off the tool.


Using a small brush and/or water, clean any debris or
trash that is trapped on the inside of the pump.

pump, check intake screen before use to make sure it is
clean.


If the pump will not run, try the following solutions:

Ensure that the intake screen is free of obstructions.

Make sure that the water line 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.
