SPECIFIC MAINTENANCE:

EVAPORATIVE EMISSION COMPONENTS:

The unit you have purchased includes the following components that are in compliance with 2006 California
Air Resources Board Evaporative Emission Standards;
1. Fuel Hose
2. Fuel Hose Fittings
These components should be inspected on a daily basis for cracks, leaks, and abnormal wear. If cracking,
leaks or abnormal wear has occurred, the components should be replaced immediately.

ENGINE:

The engine instructions that accompany your unit detail specific procedures for maintenance of the engine.
Following the engine manufacturer's recommendations will extend engine work life.

PUMP:

Change the pump oil after the first 50 hours of operation. After initial change, every 3 months or 250 hour
intervals are recommended. If oil appears dirty or milky, changes may be required in greater frequency. Use
SAE20 or 30 Non-Detergent pump oil and fill only to the center of the oil sight glass or the "Full" mark on the
dipstick. DO NOT OVERFILL.

QUICK COUPLERS:

There is an o-ring seal inside the female quick-coupler. This o-ring will deteriorate or, if the unit is allowed to
pump without the high pressure hose attached, it may be blown out occasionally. Simply insert a replace-
ment o-ring to correct the leak. (Additional o-rings can be purchased from your dealer.)

NOZZLES:

Water flow through the quick-connect spray nozzle will erode the orifice, making it larger, resulting in a pres-
sure loss. Nozzles should be replaced whenever pressure is less than 85% of the maximum. The frequency
of replacement will depend upon such variables as mineral content in the water and number of hours the
nozzle is used.

BELT TENSION ADJUSTMENT:

To maintain peak performance of your pressure washer, it may be
necessary to adjust the belt tension on occasion. Follow the proce-
dure outlined below.
1. Remove the belt guard and loosen the two nuts on each side of
the pump (Reference A). There are a total of 4 nuts.
2. Turn the cap screw (Reference B) clockwise until a 1/4 inch belt
deflection is noticed between the pulleys.
3. Tighten the side nuts (Reference A).
4. Put a straight edge across both pulleys. Pulley alignment is critical for proper performance and service
life. If necessary, loosen one set of pulley screws and adjust in or out to properly align. Tighten the
pulley screws and check the tension again.
5. Replace the beltguard and tighten the fasteners securely.

WINTERIZING:

For storage and transportation purposes in subfreezing ambient temperatures, it will be necessary to winter-
ize this unit. This unit must be protected to the lowest incurred temperature for the following reasons:
1. If any part of the pumping system becomes frozen, excessive pressure may build up in the unit which
could cause the unit to burst resulting in possible serious injury to the operator or bystanders.
2. The pumping system in this unit may be permanently damaged if frozen. FREEZE DAMAGE IS NOT
COVERED BY WARRANTY.
If you must store your unit in an area where the temperature may fall below 32°F, you can protect your unit by
following the procedure outlined below.
1. Gather the following items:
