MAINTENANCE
ENGINE AIR CLEANER
1. Remove the air cleaner cover and foam filter element
as shown in Figure 32.
2. Tap the paper filter element (Figure 32) several times
on a hard surface to remove dirt, or blow compressed
air [not exceeding 30 psi (207 kPa, 2.1 kgf/cm2)]
through the filter element from the air cleaner case
side.
NEVER
brush off dirt. Brushing will force dirt
into the fibers. Replace the paper filter element if it is
excessively dirty.
3. Clean foam element in warm, soapy water or
nonflammable solvent. Rinse and dry thoroughly. Dip
the element in clean engine oil and completely squeeze
out the excess oil from the element before installing.

STORAGE
For storage of the unit for over 30 days, the following is
required:
Drain the fuel tank completely.
Run the engine until the fuel in the carburetor is
completely consumed.
Completely drain used oil from the engine crankcase
and fill with fresh clean oil, then follow the procedure
described in the engine manual for engine storage.
Remove the drain plug from the pump and drain out any
water from left in the housing.
Remove the pump cover and clean inside of pump
housing. Coat inside of pump housing with a light film
of oil to reduce corrosion. A spray can of oil works well
for this application.
Cover pump and engine with plastic covering or
equivalent and store in a clean, dry place.
To protect the water-cooled seals, place one-half pint
of lubricating oil (new or used) through the discharge
opening on the pump and crank the engine several times.
This will prevent excessive corrosion and also keep the
mechanical seal lubricated.
Drain water tank completely.
