8Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.
8Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up
any spilled fuel immediately.
8Do not refuel right after the engine has
been running and is still very hot.
8Be sure the fuel tank cap is closed secure-
ly.
EBU01117
Engine and transmission oil
Make sure the engine and transmission oil is at
the specified level. Add oil as necessary. (See
page 8-13–8-25.)

cC
Be sure to use motor oils that do not contain
anti-friction modifiers. Passenger car motor oils
(often labeled “ENERGY CONSERVING
II”)
contain anti-friction additives which will cause
clutch and/or starter clutch slippage, resulting
in reduced component life and poor engine per-
formance.

Engine oil
Engine oil level measurement
1. Place the machine on a level surface.
2. Warm up the engine for several minutes and
stop it.
3. Remove the dipstick and wipe it off with a
clean rag. Insert the dipstick in the filler hole
without screwing it in.
NOTE:
Wait a few minutes until the oil level settles
before checking.
4. Remove the dipstick and inspect the oil level.
5. The oil level should be between the maximum
and minimum marks. If the level is low, add oil
to raise it to the proper level.
