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 Siphoning Tube
Examine detergent tube and clean if clogged. The tube
should fit tightly on the barbed fitting. Examine the tube for
leaks or tears. Replace tube if damaged.
Detergent Siphoning Check Ball
Occasionally check ball in detergent siphoning system may
become stuck from storage, dried soap, or minerals in water.
The check ball can be freed by performing the following:
NOTICE
Before performing this procedure, be sure you are
wearing safety goggles as described below.
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and squeeze spray gun trigger to release
retained high water pressure.
3. Remove detergent siphoning hose from barbed fitting
on pump.
4. Using a firm, blunt object 2 mm (7/64 in) in diameter or
smaller, by at least 2.5 cm (1 in) long, such as an Allen
wrench, slowly insert the object into the barbed fitting until
you meet resistance. This resistance is the check ball.
5. Slowly push down until you feel the ball move slightly,
push no more than 3 cm (1/8 in). Slight pressure may
be required to free the ball.
6. Repeat steps 4 and 5 if necessary.
7. Reinstall detergent siphoning hose onto barb fitting.
8. Treat with PumpSaver as described in
Protecting the
Pump
during storage to prevent reoccurrence.
Check Spray Gun
Examine the hose connection to the spray gun and make
sure it is secure. Test the trigger by pressing the red button
and making sure the trigger “springs back” into place when
you release it. You should not be able to press the trigger
without pressing the red button. Replace spray gun
immediately if it fails any of these tests.
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 spray tip
clogged or restricted with foreign materials, such as dirt, etc.
To correct the problem, immediately clean the spray tip
following these instructions:
1. Shut off engine and turn off water supply.
2. ALWAYS point spray gun in a safe direction, press red
button and squeeze spray gun trigger to release
retained high water pressure.
3. Remove spray tip from end of nozzle extension.
4. Use a small paper clip to free any foreign material
clogging or restricting spray tip (

).
5. Remove nozzle extension from spray gun.
6. Using a garden hose, remove additional debris by back
flushing water through nozzle extension. Back flush
between 30 to 60 seconds.

WARNING
The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which could result in
serious injury.
• Keep high pressure hose connected to pump and spray gun
while system is pressurized.
• ALWAYS point spray gun in safe direction, press red button
and squeeze spray gun trigger to release high pressure, every
time you stop engine.
WARNING
The high pressure stream of water that
this equipment produces could cut through skin
and its underlying tissues, resulting in serious
injury and possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST equal or exceed maximum
pressure rating of unit.
WARNING
Risk of eye injury.
Spray could splash back or propel objects
resulting in serious injury.
• Always wear indirect vented (chemical splash) safety goggles
marked to comply with AS/NZS 1337 (ANSI Z87.1 equivalent)
when using or in vicinity of this equipment.
• NEVER substitute safety glasses or dry-condition goggles for
indirect vented safety goggles.
