LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark plug wire before cleaning,
lubricating or doing any kind of work
on lawn mower.
Wheels—Wheel bearings are of self-lubricating
Fortiflex. They require no lubrication. If your unit
is provided with optional ball bearing wheels,
lubricate at least once a season with light oil.
Protective Shield—The pivot points on the protec­
tive shield should be lubricated periodically with
light oil to prevent any rust or binding.
Chute Deflector—The torsion spring and pivot
point should be lubricated periodically with light
oil to prevent any rust or binding. Deflector must
work freely.
Engine—Follow engine manual for lubrication in­
structions.
Throttle—Periodically lubricate throttle control
lever and throttle wire assembly with a few drops
of light oil (SAE No. 10 or 20) for ease of operation.
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 engine crankshaft.
2. Remove blade and blade adapter from engine
crankshaft.
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.
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 thru
drain on bottom of engine. To drain completely,
always place engine level when draining thru the
bottom. Oil capacity 1-1/4 pints. See figure 10.
