Maintenance

MAINTENANCE RECOMMENDATIONS

Regular maintenance will improve the performance and extend the life
of the power washer. See any qualified dealer for service.
The power washer's 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 the power washer
as instructed in this manual, including proper storage as detailed in
Winter Storage and Long Term Storage.
Should you have questions about replacing components on your
power washer, please call 1-888-436-3722 for assistance.
Some adjustments will need to be made periodically to properly
maintain your power washer.
All service and adjustments should be made at least once each
season. Follow the requirements in the Maintenance Schedule chart.
Once a year you should clean or replace the spark plug, clean
or replace the air filter, and check the spray gun and nozzle
extension assembly for wear. A new spark plug and clean air filter
assure proper fuel-air mixture and help your engine run better
and last longer.

EMISSIONS CONTROL

Maintenance, replacement, or repair of the emissions control
devices and systems may be performed by any non-road engine
repair establishment or individual. However, to obtain "no
charge" emissions control service, the work must be performed
by a factory authorized dealer. See the Emissions Warranty.

POWER WASHER MAINTENANCE

Clean Debris
Daily or before use, clean accumulated debris from the cleaning
system. Keep the linkage, spring and controls clean. Keep the area
around and behind the muffler free from any combustible debris.
Inspect the cooling air slots and openings on the power washer.
These openings must be kept clean and unobstructed.
Power 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.
Improper treatment of the power washer can damage it and
shorten its life.
• DO NOT insert any objects through the 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 the screen if
it is clogged, or replace the screen if damaged.

CHECK HIGH PRESSURE HOSES

The high pressure hoses can develop leaks from wear, kinking, or
abuse. Inspect the hoses 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.
The high pressure stream of water that this equipment
produces can cut through skin and its underlying
tissues, leading to serious injury, possible amputation
or death. Spray gun traps high water pressure, even
when engine is stopped and water is disconnected,
which can cause injury.
• NEVER repair high pressure hose. Replace it.
• Replacement hose rating MUST meet or exceed maximum
pressure rating of unit.

CHECK DETERGENT SIPHONING TUBE

Examine the filter on the detergent tube and clean it 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.
