Maintenance
(see figs. ¥¦§¨
Also, see Maintenance Schedule, next page. Follow
the hourly or calendar intervals, whichever occur first.
More frequent service is required when operating in
adverse conditions.
To prevent acci-
dental starting, re-
move spark plug
wire ➊ and ground
it before servicing.
CAUTION:If engine must be tipped to transport equip-
ment or to inspect or remove grass, keep spark plug
➋
side of engine up.
Transporting or tipping engine spark plug down may cause:
1. Smoking,
2. Hard starting,
3. Spark plug fouling,
4. Oil saturation of air filter.
Oil service (see fig. ¥ )
Check oil level regularly.
Be sure correct oil level is maintained. Check every 5
hours or daily, before starting engine. See oil filling
procedure, Oil Recommendations.
Change oil.
Change oil after first 5 hours of operation. Change oil while
engine is warm. Refill with new oil of recommended SAE
viscosity grade. (see fig. © )
Before tipping engine or equipment to
drain oil, drain fuel from tank by
running engine until fuel tank is empty.
If draining oil from top of engine, keep spark plug
side up.
➌
By removing drain plug with a ratchet and square
➍
extension , oil can be drained from engine bottom.
Air cleaner service (see fig. ¦ )
Replace Oil-Foam element if very dirty or damaged.
• Remove screw.
• Carefully remove air cleaner to prevent debris from falling
into carburetor.
• Take air cleaner apart and clean all parts. Wash
➊
Oil-Foam element in liquid detergent and water.
Squeeze dry in a clean cloth. Saturate Oil-Foam
element in engine oil and squeeze in a clean cloth to
remove excess oil.
• Install Oil-Foam element and cup, if equipped, in body.

Maintenance Cont'd
)
Spark plug service (see fig. § )
DO NOT check for spark with
spark plug removed. Use
only Briggs & Stratton Spark
➊
Tester , to check for spark.
DO NOT crank engine with spark plug removed. If
engine is flooded, place throttle in FAST and crank until
engine starts.
➋
Spark plug gap should be .76 mm or 0.030 in.
Replace spark plug every 100 hours or every season,
whichever occurs first. Spark plug wrench is available
from any Authorized Briggs & Stratton Service Dealer.
Note: In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this engine
was originally equipped with resistor spark plug, use
same type of spark plug for replacement.
Keep engine clean (see fig. ¨ )
Periodically remove grass and chaff build-up from
➊
engine. Clean finger guard . Do not spray engine with
water to clean because water could contaminate fuel.
Clean with a brush or compressed air.
Accumulation of debris around muf-
fler ➎ could cause a fire. Inspect and
clean before every use.
If muffler is equipped with spark arrester screen
remove spark arrester screen for cleaning and inspec-
tion. Replace if damaged.
Clean cooling system. Grass or chaff may clog engine's
air cooling system, especially after prolonged service
➋
cutting tall, dry grass. Internal cooling fins and surfaces
may require cleaning to prevent overheating and
engine damage.
➌
Remove 3 screws and lift blower housing to clean
➍
areas within heavy line .
Do not loosen 2 band brake bracket screws
Do not bend or remove flywheel guard
