at all times.
1. Remove all sticks, stones, wire and other hazardous items
from lawn before mowing. Such items are dangerous to
both the mower and individuals in the vicinity of the
mower.
2. Always disconnect spark plug cable during repairs or re
fueling operations.
3. Always start engine from side opposite discharge chute.
4. NEVER place hands or feet under mower or near dis
charge chute while engine is running.
5. Do not tilt mower at extreme angle while engine is run
ning. Cut grass on hills and banks sideways, not up and
down.
6. Always stop engine when not cutting grass.
7. Do not fill gas tank while engine is running. Do not spill
gasoline on hot engine.
8. Keep children and pets away from area at all times during
mowing operation. Never allow mower to discharge grass
toward any person.
9. Do not attempt to start engine while mower is resting in
high grass.
10. Check all nuts and bolts, particularly the blade bolts, for
tightness. This is especially important during the initial
operation period. Make this same check periodically
thereafter.
NOTE: Should excessive vibration develop, check your blade
and crankshaft immediately. Do not operate mower with an
unbalanced blade, a damaged blade or a damaged crankshaft.

FORM N0.770 1847D

OPERATION
1. Before starting engine, check LUBRICATION
INSTRUCTIONS.
2. Check lockout control handle 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 the blade engaging 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 control handle to “OFF” position.
6. Move throttle control lever to “Choke” position.
7. Crank engine. Move throttle control lever to “Fast”
position as soon as engine fires. Use choke as
needed to keep engine running during warm up period.
8. Put blade into motion by moving blade control handle
to “On” position.
3. Cutting height adjustment is made by removing and
moving axle bolts to the desired positions. Cutting
height will be raised as axle bolts are moved to
lower mounting holes and lowered as axle bolts are
moved to higher mounting holes. All axle bolts must
be mounted in the same relative position to the deck.
When wheels are mounted to the deck, the crown
shape washers must be assembled with the crown
away from the deck. This is necessary to prevent
the axle bolts from loosening.
4. If throttle adjustment becomes necessary, the throttle
control wire may be rèset as follows:
a. Loosen, but do not remove, screw securing throttle
control wire assembly at engine.
b. Move throttle control lever on handle to “Choke”
position.
c. Move lever to which control wire is fastened to
engine to full choke position. Retighten screw to
secure throttle control wire assembly.
LUBRICATION
Important: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind
of work on the lawn mower.
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 maxi
mum engine and mower life. This consists of running
the engine a 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. Wheel bearings are ball bearings. Use SAE 30
engine oil.
2. Throttle — Periodically lubricate throttle control
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 lubrication
instructions. Check oil level before each mowing.
4. Friction point between idler bracket assembly (Ref.
No.94) 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. CAUTION: Be sure spark plug wire is
disconnected and grounded.
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 the control rod. See Step 9 in
ASSEMBLY INSTRUCTIONS.
2. Control rod adjustment is made as shown in ASSEM
BLY INSTRUCTIONS Step 9.
MAINTENANCE
Important: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind
of work on the lawn mower.
1. Cutting Blade — Remove all nuts and bolts holding
the blade to the blade hub.
FORM N0.770-1847E
Page 6
When sharpening blade, follow the original angle of
of grind as a guide. It is extremely important that
each cutting edge receives an equal amount of grind
ing 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 back
ward or on its right side and scraping clean 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
engine 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 brake lever assembly.
f. Remove damaged or worn belt.
g. Place new belt on engine pulley. Do not bend
belt guard pins. Belt should be inside of pins.
h. Work belt to front and mount on blade spindle
pulley. Replace front belt guard.
i. Replace brake lever assembly.
j. Slip belt on idler pulley between pulley and belt
bracket.
k. Replace blade tension spring.
l. Move blade lockout handle to “ON” position.
m. Position belt bracket on idler pulley to clear the
tightened belt. Secure belt bracket in position.
See Drawing page “C”.
n. Replace blade spindle cover.
4. Storage — The following steps should be taken to
prepare lawn mower for storage:
a. Clean and lubricate mower thoroughly as describ
ed in the preceding instructions.
b. Refer to engine manual for correct engine storage
instructions.
c. Coat mower's cutting blade with multi-purpose
grease to prevent rusting.
d. Place blocks under deck to raise tires clear of
floor.
e. Store mower in a dry, clean area.
USING YOUR ROTARY MOWER
For best results do not cut wet grass because it tends
to stick to the underside of the mower, thus preventing
proper discharge of grass clippings. If wet grass must
be cut, reduce engine speed to help distribute the
clippings more effectively.
New grass should be treated as wet grass, otherwise a
normal walking speed is about the right pace for
efficient mowing.
The best mowing pattern is one that allows the clippings
to discharge towards the uncut part of thé lawn. This
permits recutting of the clippings to further pulverize
them. When cutting high weeds, discharge towards cut
portion then recut at right angle to first direction.
Lawns should be cut in fall as long as there is growth.
BLADE IDLER BRACKET ASSEMBLY DETAIL
BRAKE SHOE 754-647 (118)
BELT WEAR
Belt clips improperly positioned
will cause premature belt wear.
The belt clip must completely
clear the belt when the belt is
tightened. It should also assist in freeing the
belt from the blade spindle pulley when the belt
is loose. This may be checked by removing the
blade spindle cover.
