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) or 3/8 cup (Fig. 22). Check the level, See Checking
the Oil Level. If the level is low, add a small amount of
oil and recheck. Do not overfill (Fig. 22).
6. Replace the oil fill plug.
7. Reconnect the spark plug boot.
AIR FILTER MAINTENANCE
WARNING:
To avoid serious personal injury,
always turn the unit off and allow it to cool before
you clean or service it.

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 under side of
the cover inward. Then pull the air filter cover out and up.

remove excess oil (Fig. 26).
6. Replace the filter (Fig. 23).

CARBURETOR ADJUSTMENT
The idle speed of the
engine is adjustable. An
idle adjustment screw is
between the air filter cover
and the engine starter
housing (Fig. 29).
NOTE: Careless
adjustments can
seriously damage
your unit. A Sears
or other qualified
service dealer
should make
carburetor
adjustments.
Check Fuel
Old fuel is usually the reason for improper unit performance.
Drain and refill the tank with fresh fuel prior to making any
adjustments. Refer to Oil and Fuel Information.
Clean Air Filter
The condition of the air filter is important to the operation of
the unit. A dirty air filter will restrict air flow. This is often
mistaken for an out of adjustment carburetor. Check the
condition of the air filter before adjusting the idle speed screw.
Refer to Air Filter Maintenance.
