To Start
DANGER: Do not point wand or trigger gun at your-
self or at any person. Bodily injury may result from
water under high pressure.
WARNING: Wear eye, ear, hand, foot and skin protec-
tion at all times while operating pressure washer.
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage
and void warranty.
IMPORTANT: Do not allow the machine to run with
trigger of the trigger gun released for more than
10 minutes at any one time or damage to pump may
occur.
1. Turn ON water supply.
2. Hold wand firmly, release trigger of trigger gun.
3. Turn engine ON/OFF switch to ON position.
4. Turn fuel shut-off valve to ON position (if so equipped).
Move choke lever to FULL CHOKE position, (choke
may not be needed on warm engine). Move throttle
lever to HALF THROTTLE position.
5. Pull the rope starter slowly until resistance is felt, then
pull briskly. Do not allow the rope starter to snap back
against the engine. Return it gently to prevent dam-
age to the starter.
6. When the engine starts, move choke lever until
engine runs smoothly. Move throttle lever to FULL
THROTTLE position. When engine warms, move
choke lever to NO CHOKE position.
IMPORTANT: To allow for proper battery charging the
throttle control must be kept in the full throttle posi-
tion during operation.
NOTE: If engine fails to start, refer to Troubleshoot-
ing Guide in this manual.
7. Squeeze trigger of trigger gun and allow air to purge
from system.
8. If HOT water is desired, adjust the thermostat to the
proper temperature and turn burner switch ON. The
burner will light immediately with a small puff of smoke.
You may need to initially adjust your burner for peak
performance. See Oil Burner section under Installa-
tion. If smoke continues, contact Customer Service
at 1-800-771-1881. When the trigger of the trigger
gun is released or when the thermostat temperature
setting is reached, the burner will automatically turn
off.
To Clean
DANGER: Do not place hands or fingers in front of
high pressure spray. Bodily injury may result.
1. Insert detergent inlet line into container of mixed
detergent. Squeeze the trigger of the trigger gun.
Open detergent control handle on the dual lance wand,
2. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows the
detergent to soak as you work toward the top.
3. Do not wash at a 90
o
angle to work (straight at it).
This will allow water to splash back at you and
reduces your cleaning power. Wash at a 30
o
to 60
o
angle to the work. This will allow the water to splash
away from you and the water will wash the dirt away
faster and easier.
4. Use the full width of the spray pattern to wash in
a wide path. Overlap spray paths for complete
coverage. Wash from side to side, using slow, steady
motions.
5. The nozzle should be 12" to 24" from work, closer for
tough areas. Be careful on painted or delicate sur-
faces, the pressure may damage surface if nozzle is
too close.
6. Small parts should be washed in a basket so the pres-
sure does not push them away. Larger, lightweight
parts should be clamped down so the pressure does
not push them away.
7. Close the detergent control handle on the dual lance
wand to permit high pressure rinse, refer to Figure 8.
Rinse from top to bottom to prevent detergent from
dripping onto rinsed area.
To Stop
1. If detergents were used, draw clear water through the
detergent inlet line to purge detergent. Failure to do
so may clog detergent injector valve.
2. If burner was used, turn OFF burner switch and
allow pump to run cold water through coil for several
minutes.
3. Move throttle lever to idle position.
4
Turn engine ON/OFF switch to the OFF position.
5. Close fuel shut-off valve.
6. Turn water supply OFF.
7. Squeeze trigger of trigger gun to relieve system
pressure.
Figure 8 - Dual Lance Wand Operation
refer to Figure 8. The output pressure is auto-
matically reduced for detergent application. Allow
detergent to reach end of wand before proceeding to
step 2.
