OPERATION
1. Before starting engine, check LUBRICATION
INSTRUCTIONS.
2. Check lockout control handles for proper
operation. If too great a pressure is needed to
operate these controls, damage can be done
to both the mechanism and the rods.
Readjust so only slight pressure is needed to
operate both the blade engaging control and
the self-propelled lockout control. See
ASSEMBLY INSTRUCTIONS Step 9.
3. Service engine with gasoline and oil. See
engine instructions for complete care and
maintenance of engine. READ DIRECTIONS
CAREFULLY.
4. Be sure engine crankcase is filled to capacity
with proper grade of oil.
5. Move both control handles to “OFF” position.
6. Move throttle control lever to “CHOKE”
position.
7. Crank engine. Move throttle control to
“FAST” position as soon as engine fires. Usé
choke as needed to keep engine running
during warm up period.

control handle to “ON” position.
To engage the blade with the engine
running...
a. Move the throttle control lever to “FAST”
position.
b. Engage the blade engagement handle
SLOWLY.
c. Adjust engine speed.
9. A brief break-in period is essential to insure
maximum engine and mower life. This
consists of running the engine at half speed
for a period of time required to use one tank of
gasoline. It is also recommended to change
crankcase oil after the first five hours of
operation or as operating conditions dictate.
Always check oil before operating the mower.
BE SURE CRANKCASE IS FULL.
10. Proper lubrication must be maintained at all
times.
11. Appropriate clothing should be worn when
cutting brush or heavy weeds. Safety shoes
and safety glasses are highly recommended.
12. The engine is stopped by moving the throttle
control lever to “STOP” position.
ADJUSTMENT
1. Handles may be adjusted by changing the
position of the lower support mounting holes.
When this change is made, it may also be
necessary to check the adjustment of control
rod. See Step 9 in ASSEMBLY INSTRUC
TIONS.
2. Control rod adjustments are made as shown
in ASSEMBLY INSTRUCTIONS Steps 9 and
12.
3. Cutting height adjustment is made by
removing and moving axie bolts to the desired
positions. All axle bolts must be mounted in
the same relative position to the deck. When
wheels are mounted to the deck, thé crown
shape washers must be assembled with the
crown away from the deck. This is necessary
to prevent the axle bolts from loosening.

LUBRICATION
IMPORTANT
Always stop engine and disconnect
spark plug wire before cleaning, lu
bricating or doing any kind of work
on lawn mower.
6.
Protective Shield—The pivot points on the
protective shield should be lubricated period
ically with oil to prevent any rust or binding
up.
7.
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.
1. Wheels—Front wheel bearings are of selflubricating 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.
Be sure spark plug wire is discon
A
nected and grounded.
CAUTION
MAINTENANCE
IMPORTANT
Always stop engine and disconnect
spark plug wire before cieaning, lu
bricating or doing any kind of work
on lawn mower.
1.
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.
2.
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.
_ 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.
^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.
