CAUTION
FLYING OBJECT HAZARD!
ALWAYS wear eye protection when servicing the
engine and when using compressed air or high-
pressure water. Dust, flying debris, compressed
air, pressurized water or steam may injure your
eyes.
Failure to comply may result in minor or
moderate injury.
CAUTION
If any oil pump component clearance exceeds its
limit, the oil pump must be replaced as an
assembly.
CAUTION
Only use the engine oil specified. Other engine
oils may affect warranty coverage, cause
internal engine components to seize and / or
shorten engine life.
Prevent dirt and debris from contaminating the
engine oil. Carefully clean the oil cap/dipstick
and the surrounding area before you remove the
cap.
NEVER mix different types of engine oil. This
may adversely affect the lubricating properties
of the engine oil.
NEVER overfill. Overfilling may result in white
exhaust smoke, engine overspeed or internal
damage.
CAUTION
If the oil pump must be replaced, replace it as an
assembly only. Do not replace individual
components.
