circulating water in the pump can reach temperatures
above 125°F.The system engages to cool the pump by
discharging the warm water onto the ground.
CAUTION
• Starting the engine without all the hoses connected and
without the water turned ON will damage the pump.
• Damage to equipment resulting from failure to follow this
instruction will void warranty.
You must attach all hoses before you start the engine.
CAUTION
• When inserting the filter into a detergent solution bottle,
route the tube so as to keep it from inadvertently contacting
the hot muffler.
Keep the detergent siphoning tube from coming in
contact with the hot muffler.
• Keep spray nozzle between 8 to 24 inches away from cleaning
surface.
• Operate this unit on a stable surface.
• Be extremely careful if you must use the pressure washer from
a ladder, scaffolding or any other relatively unstable location.
• Firmly grasp spray gun with both hands when using high
pressure spray to avoid injury when gun kicks back.
High pressure spray could cause you to fall if
you are too close to the cleaning surface.

MAINTENANCE
Check and Clean Inlet Screen
Examine the screen on the 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 Detergent SiphoningTube
Examine the filter on the detergent tube and clean if
clogged.The tube should fit tightly on the barbed fitting.
Examine the tube for leaks or tears. Replace the filter or
tube if either is damaged.
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 trigger lock in the ON position and test the trigger.
You should not be able to press the trigger.
Check In-Line Filter
Refer to Figure 18 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 19).
5. Using a garden hose, remove additional debris by back
flushing water through nozzle extension (Figure 20).
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
ProjectPro™ 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.

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. Flush detergent siphoninhg hose by placing filter into a
pail of clean water while running pressure washer in
low pressure mode. Flush for one to two minutes.
2. Shut off engine and let it cool, then remove high
pressure and garden hoses. Disconnect spark plug wire
from spark plug.
3. Empty pump of all pumped liquids by pulling recoil
handle about 6 times.This should remove most liquid
in pump.
4. Use PumpSaver to prevent corrosion build up and
freezing of pump.
5. 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.
