Lubrication and Maintenance (Continued)
Changing Oil
IMPORTANT: Change oil after first 2 hours of
operation. Thereafter change oil every 25 hours of
operation (more often in dusty, dirty conditions). See
chart for proper type and viscosity.
NOTE: Run engine just prior to changing oil. Oil will
flow more freely and carry away more contamination
when warm.
Drain engine crankcase by removing oil drain cap.
After oil has drained, replace cap and lift hood.
Remove oil fill cap and dipstick. Pouring slowly, fill
crankcase with oil. (See specifications section for
amount of oil). Check oil level with dipstick, making
sure you replace dipstick and tighten cap firmly.
Air Cleaner
IMPORTANT: Never run engine without complete air
cleaner installed on engine.
Foam Filter
Clean and reoil every three (3) months or every 25
operating hours. Clean and reoil daily if used in
extremely dusty conditions.
Wash in water and detergent solution and squeeze
(don't twist) until all dirt is removed. Rinse thoroughly
in clear water. Wrap in a clean cloth and squeeze
(don't twist) until completely dry. Saturate with engine
oil and squeeze (don't twist) to distribute oil and
remove excess oil.
Paper Filter
Do not attempt to clean or oil filter. Replace once a
year or every 100 operating hours, more often if used
in extremely dusty conditions.
Replacement filters are available at any Authorized
Tecumseh Service Outlet.
Remove and Install Filter
Remove wing nuts and cover. Slide Filter A off Filter
B.
Inspect filter(s) for discoloration or dirt accumulation.
If either is present, service per preceding "Service
Filter" instructions. Remove nuts and Filter B.
Discard Filter B and nuts (if service is necessary).
Clean inside of cover and body thoroughly. Install
new Filter B and new nuts. Tighten nuts finger tight
and then turn one (1) more complete turn. Slide foam
filter over paper filter. Install cover and wing nuts.
Tighten wing nuts.

Oil Filter
Oil filter should be changed at every other oil change.
To change oil filter, drain engine crankcase and then
remove old filter.
Before installing replacement filter, apply a thin
coating of oil on surface of rubber seal. Also, clean
filter adapter gasket surface.
Turn filter clockwise until rubber seal contacts filter
adapter, then tighten filter an additional 2/3 to 3/4
turn.
Fill engine crankcase with new oil of the proper type
to "F" mark on dipstick.
NOTE: Oil filter requires an additional 1/2 pint of oil.
Start engine and check for oil leakage around filter
and at drain plug.
