Extreme Temperature; Water Pump Maintenance - Sawmaster T7 Owner's Manual

T7 • Owner's Manual

EXTREME TEMPERATURE

Ambient temperature below 32° F (Winter):
• To prevent the water in the pump and cooling system
from freezing, remove the water after using the machine
or when there will be a long break. Make sure that the
cooling system is entirely drained so that there is no wa-
ter left inside the pump and water hose!

WATER PUMP MAINTENANCE

When the machine has not been used for a long period
of time, hard packed dirt may begin to build up inside the
pump and block the pump wheel. If the machine is acti-
vated with the immersion pump blocked, the electric motor
of the pump will be damaged within a few minutes! Please
follow the steps listed below to clean the pump before op-
erating the saw:
1. Remove the immersion pump from the water container.
2. Clean the immersion pump.
3. Loosen the fixing screws of the pump lid.
4. Take the lid off the pump. Be careful not to damage or
lose the gasket underneath.
5. Clean the pump lid.
6. Remove all dirt and incrustations from the pump wheel.
7. Check whether the pump wheel can be easily turned.
8. Then reassemble the immersion pump correctly and
check whether it works properly.
CARBON BRUSH REPLACEMENT
1. Unplug the saw before proceeding any further.
2. Locate the carbon brush caps found on the left and right
side of the motor housing. Remove the caps (turn coun-
ter-clockwise to unscrew) to allow the carbon brushes
to spring out. (see figure 8) If they do not come out af-
ter the caps are removed, use a flat screw driver to g-
ently nudge them out.

3. When installing the new brushes, make sure they fit
snugly into the slots. Do not modify the replacement
brushes (i.e. file them down) or use non OEM brushes,
as it may damage the armature and in doing so voids
the manufacturer warranty.
4. Perform steps 1 through 3 in reverse to reinstall the fan
cover.
