formation of acids during storage.Acidic gascan damagethe
fuel system of an enginewhile in storage.
Toavoid engine problems, the fuel system should be treated
with afuel preserver or emptied before storage of 30 days or
longer. If adding a fuel preserver,fill the fuel tank with fresh
fuel. if only partially filled, air in the tank will promote fuel
deterioration during storage. If fuel preserver is not used,
drain the fuel tank, start the engine and let it run until the fuel
lines and carburetor are empty. Usefresh fuel next season.
SeeStoragefor additional information.

General Recommendations
Regularmaintenancewill improve the performanceand
extendthe life of the pressure washer. Seeany Searsor
other qualified service dealerfor service.
Thepressure washer warranty doesnot cover items that
havebeen subjectedto operator abuseor negligence.To
receivefull valuefrom the warranty, the operator must
maintain pressure washer as instructed in this manual
including proper storage as detailedin Storage.
Someadjustments will needto be madeperiodically to
properly maintain your pressure washer.
All serviceand adjustments should be madeat least once
eachseason.Follow the requirementsin the Maintenance
Schedulechart.
NOTE:Oncea year you should clean or replacethe spark
plug andreplacethe air filter. A new spark plug and clean air
filter assureproper fuel-air mixture and help your engine run
better and last longer.
Emissions Control
Maintenance, replacement,or repair of the emissions
controldevicesand systemsmay be performedby any non-
roadengine repair establishmentor individual.However,
to obtain "no charge" emissions control service,the work
must be performed by a factory authorized dealer.Seethe
Emissions Warranty.
Before Each Use
1. Checkengine oil level.
2. Cleandebris.
3. Checkwater inlet screen for damage.
4. Checkhigh pressure hosefor leaks.
5. Checkgun and nozzleextension assemblyfor leaks.
6. Purge pump of air andcontaminants.
PRESSUREWASHERMAINTENANCE
Clean Debris
Dailyor before use, cleanaccumulated debris from pressure
washer. Keeplinkage, spring and controls clean. Keeparea
around and behind muffler free from any combustible debris.
Inspectcooling air slots and openings on the pressure
washer.These openings must be keptcleanand
unobstructed.
Pressurewasher partsshould be kept cleanto reducethe
risk of overheatingand ignition of accumulated debris.
• Usea damp cloth to wipe exterior surfaces clean.

• Usea soft bristle brush to loosen cakedon dirt, oil, etc.
• Usea vacuum cleanerto pick up loose dirt and debris.
Check and Clean Inlet Screen
Examinegarden hoseinlet screen. Cleanif it is clogged or
replaceif it is torn.
Check High Pressure Hose
High pressure hoses can developleaksfrom wear,kinking,

of couplings. If any of these conditions exist, replacehose
immediately.

Nozzle Maintenance
A pulsing sensation felt while squeezingthe spray gun trigger
may be caused by excessivepump pressure.The principal
cause of excessivepump pressure is a spray tip clogged or
restricted with foreign materials,such as dirt, etc. To correct
the problem, immediately cleanthe spray tip following these
instructions:
1. Shut off engineandturn off water supply.
2. ALWAYSpoint spray gun ina safe direction, press red
