MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the pumps water inlet. Clean it if
the screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before using
it. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
Check Gun and Nozzle Extension
Examine the hose connection to the spray gun and make
sure it is secure.Test the trigger by pressing it and making
sure it “springs back” into place when you release it. Put
the safety latch in the ON position and test the trigger.You
should not be able to press the trigger.
Check In-Line Filter
Refer to Figure 21 and service the in-line filter if it
becomes clogged, as follows:
1. Detach spray gun and nozzle extension from high
pressure hose. Detach nozzle extension from spray
gun and remove o-ring and screen from nozzle
extension. Flush screen, spray gun, and nozzle
extension with clean water to clear debris.

• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.

2. If screen is damaged, o-ring kit contains a replacement
in-line filter screen and o-ring. If undamaged, reuse
screen.
3. Place in-line filter screen into threaded end of nozzle
extension. Direction does not matter. Push screen in
with eraser end of pencil until screen rests flat at
bottom of opening.Take care to not bend screen.
4. Place o-ring into recess. Push o-ring snugly against
in-line filter screen.
5. Assemble nozzle extension to spray gun.
Nozzle Maintenance
A pulsing sensation felt while squeezing the spray gun
trigger may be caused by excessive pump pressure.The
principal cause of excessive pump pressure is a nozzle
clogged or restricted with foreign materials, such as dirt,
etc.To correct the problem, immediately clean the nozzle
using the tools included with your pressure washer and
follow these instructions:
1. Shut off engine and turn off water supply.
2. Remove nozzle from end of nozzle extension.
3. Remove in-line filter from other end of nozzle
extension.
4. Use wire included in kit (or a small paper clip) to free
any foreign material clogging or restricting nozzle
(Figure 22).
5. Using a garden hose, remove additional debris by back
flushing water through nozzle extension (Figure 23).
Back flush between 30 to 60 seconds.
6. Reinstall nozzle and in-line filter into nozzle extension.
7. Reconnect nozzle extension to spray gun.
8. Reconnect water supply, turn on water, and start
engine.
9. Test pressure washer by operating with each quick
connect nozzle.
O–Ring Maintenance
Through the normal operation of your pressure washer,
o–rings, which keep the connections of the hoses and spray
gun tight and leak–free, may become worn or damaged.
Provided with your pressure washer is an O–Ring
Maintenance Kit which includes replacement o-rings, rubber
washer and water inlet filter. Refer to the instruction sheet
provided in the kit to service your unit’s o-rings. Note that
not all of the parts in the kit will be used on your unit.
To remove a worn or damaged o–ring; use a small flathead
screwdriver to get underneath the o-ring and pry it off.
Pump Maintenance
This model does not require any pump maintenance.The
pump is pre-lubricated and sealed, requiring no additional
lubrication for the life of the pump.
ENGINE MAINTENANCE
See the engine operator’s manual for instructions on how
to properly maintain the engine.
KEEP OUT OF REACH OF CHILDREN. DON'T
POLLUTE. CONSERVE RESOURCES. RETURN

Section
PREPARING UNIT FOR
STORAGE
Water should not remain in the unit for long periods of
time. Sediments or minerals can deposit on pump parts and
“freeze” pump action. If you do not plan to use the pressure
washer for more than 30 days, follow this procedure:
1. Empty all chemical reservoirs as follows:
a. Disconnect hose connected to chemical inject fitting
on pump. Place end of hose into suitable container.
b. Rotate one of the chemical shut-off valves to “On”
position and open that tanks cover. Gravity will
empty tank contents into container.
c. When first tank is empty, repeat step (b) for other
tank, using a different container.
d. Reconnect hose to chemical inject fitting on pump.
Add 0.5 liter of clean fresh water to each tank and
close tanks covers.
2. Flush chemical system by selecting one tank, turning its
chemical shut-off valve to “On” position and run
pressure washer with black nozzle. Flush until first tank
is empty.Turn its chemical shut-off valve to “Off”
position. Flush other tank the same way.
3. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
4. Empty pump of liquids by pulling engine recoil handle
about 6 times.This should remove most liquid from
pump.
5. Use pump saver to prevent corrosion build up and
freezing of pump.
6. Store unit in a clean, dry area.
Protecting the Pump
To protect the pump from damage caused by mineral
deposits or freezing, use PumpSaver to treat pump.This
prevents freeze damage and lubricates pistons and seals.
NOTE: PumpSaver is available as an optional accessory. It is
not included with the pressure washer. Contact the nearest
authorized service center to purchase PumpSaver.
To use PumpSaver, make sure the pressure washer is
turned off and disconnected from supply water. Read and
follow all instructions and warnings given on the PumpSaver
container.
NOTE: If PumpSaver is not available, draw RV antifreeze
(non-alcohol) into the pump by pouring the solution into a
3-foot section of garden hose connected to inlet adapter
and pulling recoil handle twice.
STORING THE ENGINE
See the engine operator’s manual for instructions on how
to properly prepare the engine for storage.
