The
engine is not under warranty by the mower manufacturer.
If repairs or service is needed on the engine, please contact your nearest authorized
engine service outlet. Check the "Yellow Pages" of your telephone book under
"Engines - Gasoline."
This mower should be broken in following the procedure
described in the break-in instructions. The added effort here
will double the service life of the unit. Particular attention
should be paid to the notes on alignment.
When operating this mower, unnecessary or excessive en¬
gaging of the drive pinions with the wheels should be avoided.
This is achieved by minimizing the raising and lowering of
the handle during the mowing operation. Failure to observe
is in the forward position, the drive pinions engage with
the gear tread tires and forward drive results.
6. Temporary free wheeling is achieved by depressing the
handle and raising front wheels slightly off the ground.
Self-propelled drive is resumed when handle is released...
Engine is stopped by placing control lever on handle into
"Stop" position.
this operating rule can reduce the service life of the front
tires and drive pinions substantially. When engaging the self-
propelled mechanism, a slight forward push on the mower
as the drive pinions and the gear tread tires mesh will add to
smoother and quieter operation. In addition to a smoother
operation, it will add substantially to the service life of both
the tires and the drive pinions.
HANDLE ASSEMBLY PRECAUTIONS
Although the handle is of a simple design, difficulty has
been encountered in its assembly. Certain precautions con¬
cerning its assembly must be heeded. The handle must be
assembled as shown in the diagram. Trouble arises when
certain parts are put together improperly.
A. Lockout control lever must be mounted as shown in
the illustration.
LUBRICATION
IMPORTANT:
Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind of
work on lawn mower.
WHEELS — The bearing on the rear wheels of your lawn
mower are made of Lifetime Fortiflex. No lubrication is re¬
quired. Lubricate front wheel bearing as needed.
THROTTLE — Periodically lubricate throttle control lever
and throttle wire assembly with a few drops of light oil
(S.A.E. No. 10 or 20) for ease of operations.
BRONZE BEARINGS — Periodically lubricate all bronze
bearings with a few drops of light oil (S.A.E. No. 10 or 20)
to minimize friction.
ENGINE —

BREAK-IN INSTRUCTIONS
PROTECTIVE SHIELD -
The pivot points on the pr0_
tective shield should be lubricated periodically with oil to
prevent any rust or binding up.
1. Before starting the engine, lubricate all the bronze bear¬
ings on the drive shaft. The same oil which is used for
the engine may be used for this.
Check the lockout control for proper operation. See
HANDLE ASSEMBLY PRECAUTIONS.
Check drive assembly alignment. When the lockout con¬
trol lever is moved to the Self-Propelled position (as
shown in diagram), the black nylon drive pinions should
mesh simultaneously with the gear tread tires. The lock¬
out control lever should move from Self-Propelled posi¬
tion easily.
ADJUSTMENTS
CAUTION:
Do not at any time make any adjustment to
lawn mower without first stopping engine and disconnecting
spark plug wire.
CHAIN ADJUSTMENT
1. Loosen (do not remove) two hex head cap screws. (See
illustration below.)
2. Pull pivot plate forward.
3. Tighten cap screws and check chain tension. Repeat
adjustment if necessary.
OPERATION
1. Service engine with gas and oil. See Engine Manual packed
with lawn mower for complete instructions for care and
maintenance of engine. READ DIRECTIONS CARE¬
FULLY.
2. Lubricate bronze bearings on drive shaft.
3. Check drive assembly for correct alignment (see break-in
instructions.)
4. When ready to start engine, place lockout control lever
into free wheeling position. This is done by snapping the

with instructions in Engine Manual. After engine starts,
move throttle control lever on handle to the desired
engine speed.
5. Lockout control lever may now be moved forward for
self-propelled operation. When the lockout control lever
