General Recommendations
Regular maintenance will improve the performance and
extend the life of the pressure washer. See any Sears
or other qualified service dealer for service.
The pressure washer warranty does not cover items that
have been subjected to operator abuse or negligence.
To receive full value from the warranty, the operator must
maintain pressure washer as instructed in this manual
including proper storage as detailed in Storage.
Some adjustments will need to be made periodically to
properly maintain your pressure washer.
All service and adjustments should be made at least
once each season. A new spark plug and clean air filter
assure proper fuel-air mixture and help your engine run
better and last longer. Follow the requirements in the
Maintenance Schedule chart above.

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 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 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 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.
Replace the filter 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
