empty.

Clean area around oil fill, remove oil fill cap/dipstick.

Wipe dipstick clean.

Tip your pressure washer to drain oil completely from the oil fill tube into a suitable container. When

crankcase is empty, return the pressure washer to upright position.

Fill engine crankcase with recommended oil until oil level is at FULL point on dipstick. Do not overfill above that mark. POUR SLOWLY.

When engine crankcase is filled to proper level, install and tighten oil cap/dipstick.
