Pressure Washer Maintenance - Husqvarna MAX 3100 PSI Manual Del Operario

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 could
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 the screen on the pump's water inlet. Clean it if the
screen is clogged or replace it if screen is damaged.
Check High Pressure Hose
The high pressure hose can develop leaks from wear,
kinking, or abuse. Inspect the hose each time before using
them. Check for cuts, leaks, abrasions or bulging of cover,
damage or movement of couplings. If any of these
conditions exist, replace the hose immediately.
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.
Check Detergent Siphoning Tube
Examine the detergent tank and detergent siphoning tube
and clean if clogged. The tube should fit tightly on the
barbed fitting of the pump and detergent shut-off 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.
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.
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.
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.
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 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 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 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.
