WASHING PROCEDURES
WARNING: Some detergents may
be harmful if inhaled or ingested,
causing severe nausea, fainting
or poisoning. The harmful ele-
ments may cause property dam-
age or severe injury.
DANGER: Do not place hands or
fingers in front of high pressure
spray. Bodily injury may result.
1. Test pressure and spray pattern on hard surface (i.e.
cement) to gauge distance and impact of water spray.
2. If detergents are to be used, only use detergents
intended for pressure washers. Follow instructions
on the detergent container.
3. 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.
4. 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.
5. 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.
6. The nozzle should be 12" to 24" from the work, closer
for tough areas. Be careful on painted or delicate
surfaces, the pressure may damage surface if nozzle
is too close.
7. Small parts should be washed in a basket so the
pressure does not push them away. Larger, light-
weight parts should be clamped down so the pres-
sure does not push them away.
NOTE: If pressure washer is running and not being
used for more than 2 minutes, turn off engine.
SHUTDOWN PROCEDURES
1. Move throttle lever to idle position.
2. Turn engine ON/OFF switch to the OFF position.
3. Turn fuel shut-off valve to OFF position (if so
equipped).
4. Turn water supply off.
CAUTION: Do not allow pump to run without water.
5. Squeeze trigger of trigger gun to relieve system
pressure.
STORAGE
DANGER: Do not store flammable
liquids (gasoline, diesel fuel, sol-
vents, etc.) near pressure washer,
or in non-ventilated areas.
Protect from freezing by storing in
a heated area, or by flushing the
system with antifreeze (use an
automotive engine antifreeze or
windshield washer solvent to anti-
freeze). To flush the system with an-
tifreeze, the following steps are to be followed:
1. Attach a short length of hose to the garden hose
connector located on the pump.
2. Place the other end of the hose into a container of
antifreeze.
3. Start engine and allow to run until antifreeze flows
from the end of the wand.
4. Squeeze and release the trigger of the trigger gun
several times to antifreeze the unloader system.
5. Release the trigger of the trigger gun. Stop engine.
6. Squeeze the trigger of the trigger gun to relieve sys-
tem pressure.
If the pressure washer is not to be used for an extended
length of time, it is recommended that the system be
flushed with antifreeze for rust protection. Refer to the
Gasoline Engine Manual for engine storage information.
