PRESSURE WASHER MAINTENANCE
Clean Debris
Daily or before use, clean accumulated debris from
pressure washer. Keep linkage, spring and controls
clean. Keep area around and behind muffler free from
any combustible debris. Inspect coo_ing air slots and
openings on the pressure washer. These openings
must be kept clean and unobstructed.
Pressure washer parts should be kept clean to reduce
the nsk of overheating and ignition of accumulated
debns.
• Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of pressure washer
could damage it and shorten its life.
o DO NOT insert any objects through cooling slots.
Use a soft bnstle brush to loosen caked on dirt, oil, etc.
Use a vacuum cleaner to pick up loose dirt and debris.
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it ls
clogged or replace if it is torn.
Check High Pressure Hose
High pressure hoses can develop leaks from wear,
kinking, or abuse. Inspect hose before each use.
Check for cuts, leaks, abrasions, bulging of cover, or
damage or movement of couplings. If any of these
conditions exist, replace hose immediately.
WARNmNG 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.
o NEVER repair high pressure hose. Replace it.
, Replacement hose rating MUST equaJor exceed
maximum pressure rating of unit.
Check Detergent Siphoning Tube
Examine the filter on detergent tube (if equipped) and
clean if dogged. The tube should fit tightly on the
pumps barbed fitting. Examine the tube for leaks or
tears. Replace the filter or tube if either is damaged.
Detergent Siphoning Check Ball
Occasionally the check bah in detergent siphoning
system may become stuck from storage, dried soap,
or mineraJs 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.
WARNING Risk of eye injury.
Spray could splash back or propel objects
resulting in serious injury.
Always wear indirect vented (chemical splash) safety
goggtes marked to comply with ANSI Z87.1 when using
or in vicinity of this equipment.
NEVER substitute safety gtasses or dry-condition
goggtes for indirect vented safety goggtes.
.
2.
Shut off engine and turn off water supply.
ALWAYS point spray gun in a safe direction,
press red button and squeeze spray gun trigger to
release retained high water pressure.
WARNmNG 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.
.
4o
Remove detergent siphoning hose from barbed
fitting on pump.
Using a firm, Munt object 7/64" in diameter or
smaller, by at least 1" 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 bah 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
fitting.
8. Treat with PumpSaver as described in Protect
Pump during storage to prevent reoccurrence.
Check Spray Gun
Examine hose connection to spray gun and make sure
it is secure. Test trigger by pressing it and making sure
it springs back into place when you re_ease it. Do not
depress red button and test trigger. You should not be
aMe to press trigger. Replace spray gun immediately if it
fails any of these tests.
