CARE AND MAINTENANCE:
Transmission:
The transmission is pre-lubricated and sealed at
the factory. It requires no additional lubrication
unless the transmission is disassembled. To fill
with grease, lay the left half of the chain case on
its side, add 14 ounces of Plastilube #1 grease and
assemble the right half to it. This grease can be
from your nearest Sears Service Center. (Order
Part No. 737-0133.)
Engine:
1. You MUST CHANGE THE OIL in the crankcase
after the first two hours of operation of your
new engine and after each 25 hours of use
thereafter to ensure proper lubrication of
internal parts for trouble free operation and to
prevent costly repair due to excessive wear.
(Take care to remove dirt around dip stick.) Be
sure oil level is maintained full to mark. See
figure 19.
To change oil remove drain plug (figure 34) and tip
the tiller forward while engine is warm. Replace
drain plug. Remove oil dip stick and refill with
new oil of proper grade. Replace dip stick.

Use only a good grade of fresh, clean, regular
gasoline. Do not use gasoline that has been
sitting for a long period of time. Stale
gasoline may cause engine to run poorly or
not at all.
3. Keep your engine CLEAN. Wipe off all spilled
fuel and oil. Keep the engine clean of foreign
matter and be sure the cooling fins on the
cylinder are kept clean to permit proper air
circulation. You must REMEMBER that this is
an air cooled engine and free flow of air is
essential to proper engine performance and
life.
4. Your must SERVICE YOUR AIR CLEANER.
Clean every 10 operating hours, or more often
if used in extremely dusty or dirty areas.
Proceed as follows:
A. Remove wing nut, cover and filter.
B. Tap top or bottom of filter lightly on a flat
