6. When finished cutting, shut off water supply
to the blade guard, shut off water supply at
source and remove source hose from the
saw.
7. Drain water from upper gearbox heat sink.
(
ref. maintenance instructions: upper
gearbox).
Water Pump (Optional)
The optional water pump directs water from the
water metering control valve to the saw blade.
1. Ensure all water supply lines are
connected.
2. Ensure that the water valves on the right
and left side of the saw are shut.
3. Turn on the water pump switch to start the
pump.
NOTE: DO NOT start the water pump until just
before cutting. DO NOT leave the water pump on
when the cutting task is complete to avoid draining
the battery.
4. Move the water valve lever on the right side
of the saw to the fully open position.
5. Increase or decrease water flow by
adjusting the left side water valve lever.
6. When cutting is complete, shut both water
valves.
7. Turn the water pump switch to OFF to stop
the pump.
Automatic Water System (AWS)
The automatic water system provides a
solenoid in the water supply system that works
in conjunction with the “Zero Blade” option on
the control panel. When the saw blade is
“zeroed” at the pavement surface, the solenoid
valve will allow water to flow when the blade is
lowered into a cut. When the blade is raised
out of the cut and the blade passes the “zero”
point, the water flow will automatically shut off.
NOTE: When using AWS, adjust the water
valve lever to meter the water flow. AWS will
automatically turn the water on/off when the
blade enters or exits the cut.
Cutting Guides
Use the cutting guides as needed to help
follow the cutting line. Always check the cutting
guides for proper alignment with the blade prior
to cutting.
