MAINTENANCE SCHEDULE
Perform these required maintenance procedures at the
frequency stated in the table. These procedures should also be
a part of any seasonal tune-up.
NOTE: Some maintenance procedures may require special
tools or skills. If you are unsure about these procedures
take your unit to any non-road engine repair
establishment, individual or authorized service dealer.
NOTE: Maintenance, replacement, or repair of the emission control
devices and system may be performed by any non-road engine
repair establishment, individual or authorized service dealer.
WARNING: To prevent serious injury, never
perform maintenance or repairs with unit running.
Always service and repair a cool unit. Disconnect the
spark plug wire to ensure that the unit cannot start.
CHANGING THE OIL
For a new engine, change the oil after the first 10 hours of
operation. Change the oil while the engine is still warm. The oil will
flow freely and carry away more impurities.
1. Unplug spark plug boot to prevent accidental starting.
2. Remove the oil fill plug/dipstick.
3. Pour the oil out of the
oil fill hole and into a
container by tipping the
unit to a vertical
position (Fig. 25). Allow
ample time for
complete drainage.
4. Wipe up any oil residue
on the unit and clean
up any oil that may
have spilled. Dispose of
the oil according to
Federal, State and local
regulations.
5. Refill the crankcase
with 3.04 fluid ounce
(90 ml) of SAE 30 SF, SG, SH oil.
NOTE: Use the bottle and spout saved from initial use to
measure the correct amount of oil. The top of the label on
the bottle measures approximately 3.04 ounces (90 ml) (Fig.
26). Check the level with the dipstick. If the level is low, add
a small amount of oil and recheck. Do not overfill (Fig. 26).
6. Replace the oil fill plug/dipstick.
7. Reconnect the spark plug boot.
AIR FILTER MAINTENANCE
Cleaning the Air Filter
Clean and re-oil the air filter every 10 hours of operation. It is
an important item to maintain. Failure to maintain your air filter
properly can result in poor performance or can cause
permanent damage to your engine.
1. Open the air filter cover. Push the tab on the right side of
the cover inward. Then pull the air filter cover out and to
the left (Fig. 27).
WARNING: Wear gloves to prevent injury when
handling unit.

WARNING: To avoid serious personal injury,
always turn the unit off and allow it to cool before
you clean or service it.
CHECKING THE OIL LEVEL
The importance of checking
and maintaining the proper
oil level in the crankcase
cannot be overemphasized.
Check oil before each use:
1. Stop the engine and allow
oil to drain into the
crankcase.
2. Place the unit on a flat,
level surface to get a
proper oil level reading
(Fig. 5).
3. Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the dipstick before
removing it.
4. Remove the oil fill
plug/dipstick and wipe
off oil. Reinsert it all the
way back in.
5. Remove the oil fill plug/
dipstick and check the oil
level. Oil should be up to the top of the dipstick (Fig. 23).
6. If the level is low, add a small amount of oil to the oil fill
hole and recheck (Fig. 24). Repeat this procedure until the
oil level reaches the top of the dipstick.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring is in place on the oil fill
plug/dipstick when checking and changing the oil (Fig. 24).
