Maintenance
Observe regular maintenance intervals to ensure maximum
performance and life from the pressure washer. Refer to the
schedule for recommended maintenance. If you operate the
pressure washer in dusty conditions, perform maintenance
checks more often.
ENGINE OIL CHANGING INSTRUCTIONS
Drain the engine oil when the engine is warm. Warm oil drains
quickly and completely.
1. Turn the fuel valve to the OFF position to reduce the
possibility of fuel leakage.
2. Place a suitable container next to the engine to catch the
used oil.
3. Remove the oil filler cap/dipstick and drain the oil into the
container by tipping the engine toward the oil filler neck.
Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take used oil in a sealed
container to your local recycling center or service station for
reclamation. Do not throw into the trash, oust it on the ground,
or pour it down a drain.
4. With the engine in a level position, fill to the upper limit
mark on the dipstick with the recommended oil.

PUMP OIL CHANGING INSTRUCTIONS
Changing or refilling the oil in the pump requires removal of the
pump from the engine and should not be required unless oil
has leaked out due to worn or damaged oil seals in the pump. If
oil has leaked out of the pump, bring the pressure washer to a
certified Maxus service center for repair.
