Bolens 120-270A - Manual (Page 11)

Wheels—Front and rear wheel bearings are of
self-lubricating Fortiflex. They require no lubrica­
tion.
Chute Deflector—The torsion spring and pivot
point should be lubricated periodically with light
oil (SAE No. 10 or 20) to prevent any rust or bind­
ing. Deflector must work freely.
Protective Shield—The pivot points on the protec­
tive shield should be lubricated periodically with
light oil to prevent any rust or binding.
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 for ease of operation.
Bronze Bearings—Periodically lubricate all
bronze bearings with a few drops of engine oil to
minimize friction.
Chain—The chain should be lubricated periodical­
ly with a few drops of light oil to prevent any rust
or binding. See figure 18. Use very little or no oil if
unit is being used in a dry or dusty area.
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
accumulation 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.

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).
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 to FULL mark
on dipstick.
Before removing dipstick, clean area around
dipstick to prevent dirt from entering oil fill tube.
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 19.
