Engine Description

The engine is an air cooled, 4-stroke, OHV, single cylin-

der gasoline engine. It incorporates a pressure fed lubri-

cation positive displacement oil pump with a cartridge

type full flow oil filter and a counter rotating balance

shaft.

CHECKING THE OIL LEVEL

Do not overfill engine. Too much oil may cause engine to

smoke or spark plug fouling.

Too much oil may cause smoking or allow oil to enter the

air filter enclosure.

The oil should be checked with the engine warm. The

vehicle should be on a level surface with the parking

(PARK) brake engaged. Allow adequate time for oil to

drain into the crankcase before checking.

Remove the dipstick and wipe off the entire area with a

lint free cloth (Ref. Fig. 33 on page 23).

Fig. 33 Clean Entire Dipstick

Insert the dipstick fully into the dipstick hole and

remove. Examine the level of the oil on the dipstick.

Fig. 34 Check Oil Level on Dipstick

The engine can be operated safely as long as oil is

within the safe operating range as indicated on the dip

stick. Do not operate vehicle if oil level is below the

safe area indicated on the dipstick.

Oil should be added to bring the level into the safe oper-

ating range. Remember that oil expands as it gets hot,

Do not overfill (Ref. Fig. 34 on page 23). Check that the

oil cap is firmly in place.

When adding oil between oil changes, do not mix brands and

viscosity grades of oil.

The oil dipstick/fill cap must be in place before operating the

engine. Failure to install the dipstick/fill cap will result in oil

becoming contaminated and/or oil being discharged into the

engine compartment.

Changing the Oil

Tool List Qty. Required

Socket, 3/8" drive.........................................................1

Ratchet, 3/8" drive .......................................................1

Extension, 3/8" drive, 8"...............................................1

Oil drain pan ................................................................1

Wrench 3/4" .................................................................1

For maximum performance and longevity, the engine oil

should be replaced after the first 8 hours of operation.

After the initial oil change, it should be changed every

125 hours of operation or semi-annually, whichever

comes first.

The selection of oil is dependent upon the service that

the vehicle will perform. Most vehicles require 10W-30

oil, whereas vehicles used at capacity or near capacity

load applications will utilize 10W-40 oil after a break-in

period of 100 hours (Ref. Fig. 35 on page 24).
