Service Air Cleaner
Your engine will not run properly and may be damaged if
you run it with a dirty air cleaner.
Clean or replace the foam pre-filter every 25 hours of
operation or sooner under dusty or dirty conditions. Clean or
replace the paper air filter every 100 hours of operation or
yearly, whichever comes first. Clean or replace more often if
operating under dusty or dirty conditions.
To service the air cleaner, follow these steps:
1. Loosen screws (A) and remove air cleaner cover (B).
2. Carefully remove foam pre-filter (C) and paper filter (D).
3. Wipe clean inside of base (E) and cover thoroughly.
4. To clean or replace the foam pre-filter, wash pre-filter
in a solution of household detergent and warm water,
then rinse thoroughly. Squeeze dry in a clean cloth.
5. DO NOT oil foam pre-cleaner.
6. Clean paper filter by tapping it gently on a solid surface.
If the paper filter is too dirty, replace it with a new one.
Dispose of the old filter properly.

the paper filter.

screws.
Service Spark Plug
Change the spark plug every 100 hours of operation or once
each year, whichever comes first. This will help your engine
to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and reset
spark plug gap to recommended gap if necessary (see
Specifications).

Clean Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a Briggs & Stratton
authorized dealer clean the cooling system (F) per
recommended intervals (see Maintenance Schedule in the
Maintenance section). Equally important is to keep top of
engine free from debris. Also see Cleaning.
