MAINTENANCE
HIGH FLOW AIR CLEANER MAINTENANCE
Perform this maintenance every 25 hours or every season,
clean more often under dusty conditions or when airborne
debris is present. This filter is made of cotton, which is
different from a standard paper filter, therefore it MUST be
oiled.
[1] Remove clamp and pull air cleaner from intake
manifold.
[2] Remove as much dirt from the filter as possible.
[3] Using the High Flow Air Filter Cleaner Kit, Briggs &
Stratton part no. 5089D, spray the filter with cleaner.
Allow the solution to soak in to the filter for about 15
minutes.
CAUTION: Never use strong detergents, high
pressure water, or gasoline to clean this filter.
[4] Rinse the filter with warm water, inside first and then
outside. (Let the water run from the clean side to the
dirty side.)
[5] Allow the filter to dry completely. It is best to allow the
filter to dry naturally. Don’t use heat, this might shrink
the cotton.
[6] Use only air filter oil, such as the oil included in the
cleaning kit (P/N 5089D), to re-oil the filter.
WARNING
Never use motor oil, transmission fluid, WD40, or other
oils. Failure to follow instructions can cause fires
resulting in death or serious injury. Use only air filter oil
designed specifically for air filters.
[7] Spray the filter with oil, or pour small amount onto
each pleat and allow filter to stand for 20 minutes. The
filter is correctly oiled when the cotton changes from
white to the color of the oil.
CAUTION: DO NOT over-oil air filter, it will interfere
with engine performance and may cause engine
damage. If the filter is placed on cardboard for 10
minutes and leaves a stain, it is over oiled. Wash/clean
and re-oil per above instructions.
[8] Re-install air filter.

OIL FILTER (IF EQUIPPED)
Replace oil filter after every 100 hours of operation.
[1] Drain engine oil and remove oil filter.
[2] Before installing new filter, lightly oil filter gasket with
fresh, clean engine oil.

adapter. Tighten 1/2 to 3/4 turn more.
[4] Add fresh oil. Fill to FULL line on dipstick.
[5] Start and run engine at idle to check for oil leaks.
[6] Stop engine. Recheck oil level and add oil if required.
OIL PRESSURE
If oil pressure drops too low, an oil pressure switch (if
engine is equipped) will either activate a warning light or
stop the engine. Check oil level with dipstick. If oil level is
between ADD and FULL mark on dipstick, Do not try to
restart engine. Contact an Authorized Briggs & Stratton
Service Dealer. Do not operate engine until oil pressure is
corrected.
If oil level is below ADD mark on dipstick, add oil to bring
level to FULL mark. Restart engine and check oil pressure.
If pressure is normal, continue to operate engine.
Note: Oil pressure gauge, if engine is equipped, is supplied
by manufacturer of equipment.
