SERVICING

Servicing refers to general maintenance procedures to
be performed by qualified service personnel.

MODEL IDENTIFICATION

Engine Serial Number

The engine number is stamped on the rear left hand
side of the cylinder body.

AIR CLEANER

Oil Wetted (Viscous) Type Paper Element.

The air cleaner has an oil wetted paper element. No
servicing is required until the replacement interval is
reached.
Never attempt to clean the element, no matter how dirty
it may appear. The element is designed to provide
normal filtering efficiency until it becomes due for
replacement.
Refer to the Item “Service and Maintenance” in the
Owner’s and Driver’s Manual for general service
information.

LUBRICATING SYSTEM

Main Oil Filter (Cartridge Type Paper Element)

Replacement Procedure

1. Loosen the drain plug to drain the engine oil.
2. Wait a few minutes and then retighten the drain

plug.

3. Loosen the used oil filter by turning it counter-

clockwise with the filter wrench.

4. Clean the oil cooler fitting face.

This will allow the new oil filter to seat properly.

5. Apply a light coat of engine oil to the O-ring.
6. Turn the new oil filter until the filter O-ring is fitted

against the sealing face.

7. Use the filter wrench to turn the filter additional one

and 1/4 turns.
