IMPORTANT: The trigger gun provided with this pres-
sure washer is equipped with a manual trigger lock
to prevent accidental operation of the trigger gun.
(Refer to Figure 7.) The manual trigger lock should be
used whenever the trigger gun is not in use.
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 start-
ing. 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. Place engine ON/OFF switch in the ON position.
4. Open fuel shutoff valve (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. When engine warms, move
choke lever to NO CHOKE position. Move throttle
lever to FULL THROTTLE 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 Troubleshooting
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 1-303-792-5200. 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.
The detergent injector valve operates by reducing the
volume of water, thus a vacuum is achieved and detergent
is drawn into the system. DO NOT reduce the water inlet
flow so the pump cavitates due to water starvation.
Operating a pump with insufficient water will damage
the pump seals.
1. Insert detergent inlet line into container of mixed
detergent.
2. Completely open detergent control knob located on
the side of the detergent injector valve. Refer to
Figure 8.
3. Start the detergent suction by rotating the water
adjustment knob of the detergent injector valve.
Refer to Figure 8. Turning the knob counterclockwise
will pull detergent into the system. The flow may be
observed through the clear detergent line. Secure the
knob position with the knurled nut.
4. The side detergent control knob can now be adjusted
to meter the desired amount of detergent.
5. 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.
6. Do not wash at a 90
o
angle to the 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.
7. Use the width of the spray pattern to wash in a wide
path. Overlap spray paths for complete coverage
washing from side to side, using slow, steady
motions.
