CYLINDER FILTER
Fig. 7
This filter
Ê
is made of cotton, which is different from a
standard paper filter, it MUST be oiled.
1. Spray the filter with air filter cleaning solution. Allow filter
to soak in solution for 15 minutes.
CAUTION:
Never use detergents, high pres-
sure water, or gasoline to clean this filter.
2. Rinse the filter with warm water. Let the water run from
clean side to the dirty side.
3. Allow filter to dry completely. It is best to allow the filter to
dry naturally. Do not use heat, this may shrink the cotton.
4. 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.
5. Pour or spray a small amount on each pleat. Allow the oil
to soak into the filter for 20 minutes. The filter is correctly
oiled when the cotton changes 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.

STORAGE
Engines stored over 30 days need to be protected or drained of
fuel to prevent gum from forming in fuel system or on essential
carburetor parts.
For engine protection, we recommend use of Briggs & Stratton
Fuel Stabilizer available from an Authorized Briggs & Stratton
Service Dealer. Mix stabilizer with fuel in fuel tank or storage
container. Run engine for a short time to circulate stabilizer
through carburetor. Engine and fuel can be stored up to 24
months.
Note: If stabilizer is not used or if engine is operating on
gasoline containing alcohol, e.g. gasohol, remove all fuel from
tank and run engine until it stops from lack of fuel.
1. Change oil.
2. Remove spark plug and pour about 30 ml (1 oz) of
engine oil into cylinder. Replace spark plug and crank
slowly to distribute oil.
3. Clean grass and chaff from cylinder and cylinder head
fins, under finger guard and behind muffler.
4. Store in a clean and dry area, but NOT near a stove,
furnace or water heater which uses a pilot light or any
device that can create a spark.
