ENGINE OIL CHANGING INSTRUCTIONS
Drain the engine oil when th 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 envirionment. 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 postion, fill to the upper limit
mark on the dipstick with the recommended oil.
Running the engine with a low oil level
can cause engine damage.
5. Reinstall the oil filler cap/dipstick securely.

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 Campbell Hausfeld service center for
repair.
