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.
