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/Tank
Examine the detergent tank and detergent siphoning
tube and clean if clogged. The tube should t tightly on
the barbed tting of the pump and detergent shut-o
valve. Examine the tube for leaks or tears. Replace the
tank or tube if either is 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 o engine and turn o 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
tting on pump.
4. Using a rm, blunt object 7/64” in diameter or
smaller, by at least 1” long, such as an Allen
wrench, slowly insert the object into the barbed
tting 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 1/8”. Slight pressure
may be required to free the ball.
6. Repeat steps 4 and 5 if necessary.
7. Reinstall detergent siphoning hose onto barb
tting.
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 nozzle clogged or restricted with foreign materials,
such as dirt, etc. To correct the problem, immediately
clean the nozzle following these instructions:
1. Shut o engine and turn o 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 nozzle selector from end of nozzle
extension.
4. Use a small paper clip to free any foreign material
clogging or restricting any of the nozzles (A).
5. Remove nozzle extension from spray gun.

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 ANSI Z87.1 when using
or in vicinity of this equipment.
• NEVER substitute safety glasses or dry-condition
goggles for indirect vented safety goggles.
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.
