LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark plug wire before cleaning, lu­
bricating or doing any kind of work
on lawn mower.
1. Wheels—Front wheel bearings are of self-
lubricating Fortiflex. They require no lubrica­
tion. Rear wheels of Lifetime graphoil
bearings require little lubrication. A light film
of oil applied to these bearings will reduce
normal friction.
2. Throttle—Periodically lubricate throttle con­
trol lever and entire length of throttle wire
assembly with a few drops of SAE 30 engine
oil for ease of operation.
3. Engine—Follow engine manual for lubrica­
tion instructions. Check oil level before each
mowing.
4. Friction point between idler bracket assembly
(Ref. No. 18 on page 10) and deck should be
greased once each season with a multi­
purpose grease.
5. Blade Spindle Assembly—The Blade Spindle
Assembly is equipped with a grease fitting.
Use grass discharge chute for access to the
fitting located under the deck. Use multi­
purpose grease. Lubricate PRIOR to initial
use and every 25 hours thereafter.
A
CAUTION
Be sure spark plug wire is discon­
nected and grounded.
_ Filler
Plug^
^NOTE
FILL AND DRAIN OIL FROM OIL
FILL PLUG.
Always disconnect spark plug cable during
repairs, refueling or changing oil. Engine oil may
be drained through oil filler opening by tilting the
mower on its side. Change oil after first 5 hours of
operation while engine is warm. Thereafter,
change oil every 25 hours of operation while
engine is warm.

Protective Shield—The pivot points on the
protective shield should be lubricated period­
ically with oil to prevent any rust or binding
up.
Chute Deflector—The torsion spring and pivot
point shouid be iubricated periodically with
oil to prevent any rust or binding up. Deflector
must work freely.

IMPORTANT
Always stop engine and disconnect
spark plug wire before cieaning, lu­
bricating or doing any kind of work
on lawn mower.
Cutting Blade—Remove all nuts and bolts
holding the blade to the blade hub.
When sharpening the 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 unbalanced
blade will cause excessive vibration when
rotating at high speeds and may cause
damage to the mower. Upon reassembling,
make certain all parts are assembled properly
and tightened securely.
Deck—The underside of mower deck should
be cleaned after each period of use as grass
clippings, leaves, dirt and other matter
accumulates. 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 next cutting.
The deck may be cleaned by tilting the mower
backward or on its side and scraping ciean
with a suitable tool or by washing with a
stream of water from a garden hose.
^CAUTION
Do not direct the stream of water at
a hot engine as damage to the en­
gine may result.
3. Belt replacement may be made as follows:
a. Remove blade spindle cover.
b. Remove front belt guard.
c. Remove blade tension spring.
d. Loosen belt on bracket of idler bearing
assembly.
e. Remove bracket lever assembly.
f. Remove damaged or worn belt.
