Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking,
or abuse. Inspect hose before each use. Checkfor cuts,
leaks, abrasions, bulging of cover, or damageor movement
of couplings. If any of these conditions exist, replace hose
immediately.
A 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 repairhigh pressure hose.Replace it.
= Replacement hoseratingMUSTequalor exceed maximum
pressure ratingof unit.
Check DetergentSiphoning Tube
Examine the filter on detergent tube (if equipped) and clean if
clogged. The tube should fit tightly on the barbed fitting.
Examine the tube for leaks or tears. Replacethe filter or tube
if either is damaged.
DetergentSiphoning Check Bail
Occasionally check ball in detergent siphoning system may
become stuck from storage, dried soap, or minerals in water.
The check bail can be freed by performing the following:
NOTICE Before performing this procedure, be sure you are
wearing safety goggles as described below.
,A 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.
= NEVERsubstitute safety glasses or dry-condition goggles for
indirect vented safety goggles.
.
Shut off engine and turn off water supply.
ALWAYS point spray gun in a safe direction, press red
button and squeezespray gun trigger to releaseretained
high water pressure.
,_. 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.
• Keephigh pressure hoseconnected to pumpand spraygun
whilesystemis pressurized.
• ALWAYSpointspraygun in safedirection,pressred button
andsqueeze sprayguntriggerto release highpressure, e very
time you stop engine.
3.
Remove detergent siphoning hose from barbed fitting on
pump.
4.
Using a firm, blunt object 7/64" in diameter or smaller,
by at least 1" long, such as an Alien wrench, slowly
insert the object into the barbed fitting until you meet
resistance. This resistance is the check bali.
.
Slowly push down until you feel the ball move slightly,
push no more than 1/8". Slight pressure may be required
to free the bail.
6.
Repeatsteps 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.
CheckSpray Gun
Examinehose connection to spray gun and make sure it is
secure.Test trigger by pressing it and making sure it springs
back into placewhen you releaseit. Do not depress red button
and test trigger. You should not be able to press trigger.
Replacespray gun immediately if it fails any of these tests.
SprayTip Maintenance
A pulsing sensation felt while squeezing the spray gun trigger
may be caused by excessive pump pressure. The principal
cause of excessivepump 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 squeezespray gun trigger to releaseretained
high water pressure.

Use a small paper clip to free any foreign material
clogging or restricting spray tip (A).
5.
Remove nozzle extension from spray gun.
6.
Using a garden hose, remove additional debris by back
flushing water through nozzleextension. Back flush
between 30 to 60 seconds.
