Your rotary mower is a precision piece of power equip
ment, not a plaything. Therefore exercise extreme caution
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 f>fits 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.
11. While operating the mower, if any foreign object is struck,
stop the mower and inspect for damage. Do not restart
or operate the mower until all damage has been repaired.
WARNING: Should excessive vibration develop, check your blade and blade shaft immediately.
Do not operate mower with an unbalanced blade, a damaged blade or a damaged blade shaft.

ASSEMBLY
Your new mower is shipped completely assembled with the
exception of the handle.
1. Remove lawn mower and all parts from carton. Make
certain that all loose parts and literature are removed
from carton before carton is discarded.
2. Extend throttle control assembly, which is attached to
rear of mower and place on floor. CAUTION: Do not bend
or kink control wire.
3. (a) Snap lower handle into position on two lugs which
extend from the handle brackets mounted on the rear
of the frame assembly.
(b) Assemble the two upper handle parts with cap screws
and locknuts provided in parts bag. The yellow cap
screw should be used to attach throttle control assem
bly to upper handle as shown in diagram. Do not
tighten nuts.
(c) Attach upper handle assembly to lower handle with
cap screws and locknuts. Tighten all nuts.
(d) Secure control wire to lower handle with cable clips.
4. Check blade bolts for proper tightness.
5. See initial belt adjustment under Adjustment Section on
page “D”.
OPERATION
NOTE: For shipping purposes your mower is set with the
v/heels in a low cutting height position. For best results
raise the cutting position until it is determined which
height is best for your lawn. See adjustments.
1. Service engine with gas and oil. See Engine Manual pack
ed with lawn mower for complete instructions for the care
and maintenance of engine. Read Directions Carefully.
2. When ready to start engine, place throttle control lever,
on handle, in “Choke” position and start engine in
accordance with instructions in Engine Manual. After
engine starts, move throttle control lever, on handle, to
desired engine speed. The engine is stopped by placing
control lever on handle in the “Stop” position.
3. Be sure that lawn is clear of stones, sticks, wire or other
objects which could damage lawn mower or engine. For
best results and to insure more even grass distribution,
do not mow when lawn is excessively wet.
FORM NO. 770-2874C
ADJUSTMENTS
CAUTION: Do not at any time make any adjustment to
lawn mower without first stopping engine and discon
necting spark plug wire.
CUTTING HEIGHT - An adjusting plate and thumb
lever at each front wheel position provides cutting
height adjustment. Each adjusting plate has five holes.
Height of cut will be changed when the thumb lever is
moved from one hole to another. Simply depress thumb
lever towards wheel and move wheel and lever assembly
to desired position. Cutting height will be raised as
lever is moved toward front and lowered as lever is
moved toward rear.
Adjustment maybe made to the rear wheels by removing
and moving wheel studs to desired position. Cutting
heights will be raised as wheel studs are moved to a
lower hole and lowered as wheel studs are moved to a
higher hole in the deck. All wheels must be positioned
in relative height of cut positions.
THROTTLE — If adjustment becomes necessary, the
control wire assembly can be reset as follows:
1. Loosen, but do not remove, screw securing throttle
control wire assembly at engine.
2. Move throttle control lever on handle to “CHOKE”
position.
3. Move lever, to which control wire is fastened at
engine, to full choke position and retighten screw to
secure throttle control wire assembly.
BELT ADJUSTMENT - After the first one-half hour of
operation the slack in the belt must be taken up. After
this initial adjustment the belt will require only check
ing after every 25 hours of operation. To tighten the
belt, remove the three truss head machine screws (46)
and lockwashers (47) and remove the blade spindle
cover (52). Loosen the three hex nuts (60) holding the
engine to the frame assembly (29) and pull the engine
back until the belt (51) has a 1/4” deflection when
depressed by hand. Tighten the hex nuts (60) and
reassemble shroud.
MAINTENANCE
CUTTING BLADE - The blade may easily be removed
grinding or replacement as follows;
1. Remove bolt and lock washer holding blade and hub
assembly to blade spindle.
2. Remove blade and hub assembly from blade spindle.
3. Remove two bolts, lock washers and nuts holding
blade to blade hub.
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 unbalanced blade will
cause excessive vibration when rotating at high speeds
and may cause damage to the mower.
Upon reassembly, make certain all parts are assembled
properly and tightened securely.
DECK — The underside of mower deck should be cleanafter 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
corrosion and may cause an uneven discharge of grass
clippings at the next cutting.
The deck may be cleaned by tilting the mower forward
or on its left 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.
STORAGE — The following steps should be taken to
prepare lawn mower for storage.
1. Clean and lubricate mower thoroughly as described
in the preceding instructions.
2. Refer to Engine Manual for correct engine storage
instructions.
3. Coat mower’s cutting blade with chassis grease to
prevent rusting.
4. Place blocks under deck to raise tires clear of floor.
5. Store mower in a dry clean area.
LUBRICATION
IMPORTANT: Always stop engine and disconnect spark
plug wire before cleaning, lubricating or doing any kind
of work on lawn mower.
WHEELS — Front wheel bearings of Fortiflex require
no lubrication. Rear wheels of Lifetime graphoil bear
ings require little lubrication. A light film of oil
applied to these bearings will reduce normal friction.
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 operation.
ENGINE — Follow Engine Manual for lubrication
instructions.
USING YOUR ROTARY MOWER
For best results do not cut wet grass because it tends
to stick to underside of the mower thus preventing
proper discharge of grass clippings. If wet grass must
be cut reduce engine speed and walking 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 clip
pings to discharge towards the uncut part of the lawn.
This permits recutting of the clippings to further
pulverize them. When cutting high weeds, discharge
towards cut portion then recut at right angles to first
direction.
Lawn should be cut in the fall as long as there is growth.
