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. Follow the requirements in the Maintenance
Schedule chart above.
NOTICE Once a year you should clean or replace the spark
plug and replace the air filter. A new spark plug and clean air
filter assure proper fuel-air mixture and help your engine run
better and last longer.
Pump Oil
DO NOT attempt any oil maintenance on this pump. The
pump is pre-lubricated and sealed from the factory, requiring
no additional maintenance for the life of the pump.

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.
