7. Do not allow the machine to operate in the bypass mode (with the trigger
gun closed) for more than three minutes without triggering the gun. Failure
to follow this simple rule can cause premature failure of the pump packings.
HOT WATER OPERATION:
1. Follow preceding steps 1-7 for "Start-up / Cold water operation".
2. Move the Burner switch to the ON position.
3. Recheck the system for fuel leaks. If a fuel leak is found, TURN MACHINE
OFF IMMEDIATELY! See "Risk of Explosion or Fire" warnings. Be sure
that all damaged parts are replaced and that all mechanical problems have
been corrected prior to operation of the unit. Contact Customer Service
if necessary.
WARNING RISK OF BURN! THE WATER TEMPERATURE COULD
BECOME VERY HOT DURING HOT WATER OPERATION.
CAUTIOUS WHEN ADJUSTING PRESSURE OR CONTROLLING
THE TRIGGER GUN/LANCE ASSEMBLY.
Note: Upon initial start-up, water will begin turning hot in approximately
20 seconds and will reach maximum temperature within 2-1/2 min-
utes providing that the trigger gun remains open. The burner will not
fire when the trigger is released.
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.

This nozzle is sized for operation with the unloader and steam valve (where
applicable) to provide high pressure wet steam. Replacement of this nozzle
with an improperly sized nozzle may cause operational problems with the
machine.
