MAINTENANCE
CUTTING BLADE
The blade may easily be removed for grinding or
replacement as follows:
1. Remove bolt and lock washer holding blade
and blade adapter to blade spindle.
2. Remove blade and blade adapter from blade
spindle.
3. Remove two bolts, lock washers and nuts
holding blade to blade adapter (if necessary).
When sharpening blade, follow the original angle
of grind as a guide. It is extremely important that
each cutting edge receives an equal amount of
grinding to prevent an unbalanced blade. An un­
balanced blade will cause excessive vibration
when rotating at high speeds and may cause
damage to the mower.
To insure safe operation of your unit, ALL nuts
and bolts must be checked periodically for correct
tightness.
DECK
The underside of mower deck should be cleaned
after each period of use as grass clippings, leaves,
dirt and other matter will accumulate. This ac­
cumulation of grass clippings, etc., is undesirable
as it will invite rust and corrosion and may cause
an uneven discharge of grass clippings at the next
cutting.
The deck may be cleaned by tilting the mower for­
ward or on its side and scraping clean with a
suitable tool or by washing with a stream of water
from a garden hose.
A
CAUTION
Do not direct the stream of water at
a hot engine as damage to the
engine may result.
ENGINE OIL
Check Oil Level before starting engine and
after every 5 hours of operation or each period of
use.
ADD oil as necessary to keep level FULL TO
POINT OF OVERFLOWING.
Before removing oil fill plug, clean area around
plug to prevent dirt from entering oil fill hole.
Engine should be in a level position when check­
ing oil.
Change Oil after first 5 hours of operation.
Thereafter change every 25 hours. Change oil
while engine is warm. Oil may be drained from oil
fill hole by tipping unit on its side. Oil capacity
pints. See figure 5.
AIR CLEANER
Clean Air Cleaner and re-oil element every 25
hours under normal conditions. Clean every few
hours
under extremely dusty conditions. Poor
engine performance and flooding usually in­
dicates that the air cleaner should be serviced.
See figure 6.
1. Remove screw.
2. Remove air cleaner carefully to prevent dirt
from entering carburetor.
3. Take air cleaner apart and clean.
a. WASH foam element in kerosene or a liq­
uid detergent and water to remove dirt.
b. DRY foam completely by wrapping and
squeezing in a cloth.
c. SOAK foam with engine oil. Squeeze to
distribute and remove excess oil.
4. Reassemble parts and fasten to carburetor.
