2. Turn on water at faucet. Check for water leaks; tighten
as needed.
3. Pull wand coupler collar back and insert desired pres-
sure nozzle into wand coupler then secure by push-
ing coupler collar forward.
NOTE: Variable pressure control wand handle must
be turned clockwise to enable water to flow out of
the high pressure nozzle.
4. Pull spray gun trigger to relieve pressure. Read en-
gine manual provided and pull choke. Turn engine
switch to the START position and hold it there until
the engine starts. NOTE: Do not engage electric
starter for more than five (5) seconds at a time. If
engine fails to start, release the switch, pull spray
gun trigger to relieve pressure and wait ten seconds
before operating the start again. When the engine

GENERAL WASHING
TECHNIQUES
1. Hold spray nozzle approximately one foot from the
surface being cleaned. Spray at an angle to get un-
der the material and lift it off.
2. When detergent is required for cleaning, start wash-
ing from the bottom and work up. Better detergent
economy and faster results will be obtained by al-
lowing the chemical to set 5-10 minutes. After wash-
ing, rinse from the top down.
3. Cleaning heavy dirt or material away with a hard
stream of clear water is recommended before using
a cleaning agent.

SHUT DOWN PROCEDURES

any soap residue.
2. Turn burner switch off and continue spraying, allow-
ing the water to cool to below 100°F.
3. Turn engine key switch off.
4. Turn off water supply.
5. Squeeze trigger on spray gun to relieve remaining
pressure.
6. Remove water supply hose.
7. In freezing conditions, disconnect water, drain float
tank and add a 50/50 mixture of anti-freeze. Start
the machine and squeeze trigger on spray gun to
allow the mixture to flow out of the wand. Now turn
off the engine. See Winterizing Procedures under
Maintenance and Service.
CAUTION: Do not allow pump to run longer than 5
minutes without water. Disconnect all hoses to al-
low water to drain.
With machine off, open spray gun to release pres-
sure before removing discharge hose.
