Pressure Washers
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
Before tipping the engine or equipment to
drain oil, drain fuel from the fuel tank.
NOTE
: Change oil while the engine is cool.
1. Disconnect the spark plug wire from the spark plug.
2. Locate, and if accessible, remove the engine oil drain
plug (if the engine is equipped with an oil drain plug,
the drain plug is located in at least one of the locations
shown in Figure 19). If the engine oil drain plug is not
accessible or if the engine is not equipped with an oil
drain plug, tip the unit on its side to drain the oil out of
the oil fill tube (See Figure 19).
NOTE
: If draining oil from the oil fill tube, keep the air cleaner
side up.
3. Drain old oil.
4. Replace the drain plug and set the unit upright.
5. Refill the unit with new oil of a recommended type and
quantity. Fill the unit to the proper level shown on the dipstick
(if provided). Otherwise, fill the unit to the top of the oil filler
neck.

CAUTION
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.
