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 cooling 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
risk of overheating and ignition of accumulated debris.
•
Use a damp cloth to wipe exterior surfaces clean.
NOTICE Improper treatment of pressure washer can
damage it and shorten its life.
• DO NOT insert any objects through cooling slots.
•
Use a soft bristle 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 is 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.
WARNING The high pressure stream of water that
this equipment produces can cut through skin
and its underlying tissues, leading to serious
injury and possible amputation.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST exceed maximum pressure
rating of unit.
Check Gun and Spray Tip Extension
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 release it. Do not depress red button
and test trigger. You should not be able to press trigger. Replace
spray gun immediately if it fails any of these tests.
Spray Tip 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 and squeeze spray gun trigger to release
retained high water pressure.
WARNING The high pressure stream of water that
this equipment produces can cut through skin
and its underlying tissues, leading to serious
injury and possible amputation.
Spray gun traps high water pressure, even when engine is
stopped and water is disconnected, which can cause
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.
