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.
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.
