OPERATING INSTRUCTIONS
SHUTDOWN:
1. Move the Burner switch to the OFF position.
2. Squeeze the trigger and discharge the water for a period of three minutes
to cool the heat exchanger and high pressure hose. Insufficient cool-down
periods for the high pressure hose will cause excessive wear and eventual
rupture of the hose.
3. Do not close the choke to stop the engine. Backfire or engine damage
may occur.
4. Move the engine key switch to the OFF position.
5. Turn off the water supply and trigger the gun momentarily to relieve trapped
pressure.
Disconnect and drain the high pressure hose, gun, and lance. Wipe the unit
clean. Store in a non-freezing environment.
OPTIONS:
ADJUSTABLE THERMOSTAT:
Regulates the maximum discharge temperature. Turn the dial to the desired
maximum discharge temperature. This may cause the burner to fire intermit-
tently.
BALL VALVE: (AUXILIARY TANK)
1. Connect hose from auxiliary tank to open port on the 3-way ball valve.
2. Use the selector lever on the ball valve to allow water to flow from the
auxiliary tank to the pump.
3. The water level in the auxiliary tank must always be higher than the pump
inlet. This will ensure gravity feed of water to the pump. Failure to keep the
water level above the pump inlet will result in the pump running dry and
damage to the wet end of the pump.
