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 either side on the rear of the deck.
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

LUBRICATION
IMPORTANT: Always stop engine and disconnect spark plug
wire before cleaning, lubricating or doing any kind of work
on lawn mower.
WHEELS - Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
THROTTLE - Periodically lubricate throttle control lever
and throttle wire assembly with a few drops of li^t oil
(S.A.E. No. 10 or 20) for ease of operation.
ENGINE - Follow engine manual for lubrication instructions.
MAINTENANCE
CUTTING BLADE: The blade may easily be removed for
grinding or replacement as follows:
1. Remove bolt and lock washer holding blade and hub
assembly to engine crankshaft.
2. Remove blade and hub assembly from engine crankshaft.
3. Remove two bolts, lock washers and nuts holding blade
to blade hub.
When sharpening blade, follow the original angle of grind as
OPERATION
NOTE: For shipping purposes your mower is set with the
wheels 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 packed
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 “START” position and start engine in accord
ance 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.
a guide. It is extremely important that each cutting edge
receives an equal amount ofgrindingto preventan 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 cleaned
after 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 rust and
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
washingwith a stream of water froma gardenhose. CAUTION:
Do not direct the stream of water at a hot engine as damage
to the engine may result.
ADJUSTMENTS
CAUTION: Do not at any time make any adjustment to lawn
mower without first stopping engine and disconnecting spark
plug wire.
EASY CUTTING HEIGHT - An adjusting plate and thumb
lever at each wheel position provides cutting height adjust
ment. 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. All wheels must be positioned in
relative height of cut positions.
STANDARD CUTTING HEIGHT-Adjustment maybe made by
removing and movingwheel studs to desired position. Cutting
heists 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 wheel studs must be mounted in a relative
position to the deck.
THROTTLE - If adjustment becomes necessary, the throttle
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 “FAST” position.
3. Move lever, to which control wire is fastened at engine,
to full open position and retighten screw to secure
throttle control wire assembly.
FORM NO. 770-23820 PRINTED IN U.S.A.
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 bladewith chassis grease to prevent
rusting.
4. Place blocks under deck to raise tires clear of floor.
5. Store mower in a dry , clean area.
USING YOUR ROTARY MOWER
For the 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 and walking speed to help distribute the clip
pings 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 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.
