ASSEMBLY INSTRUCTIONS
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
maintenance of engine. READ DIRECTIONS CARE­
FULLY.
2. When ready to start engine, place throttle control lever in
“START” position and start engine in accordance with
instructions in Engine Manual. After engine starts, move
throttle control lever to desired engine speed. The engine
is stopped by placing control lever in the “STOP” po­
sition.
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.
4. Check blade bolts for proper tightness.
ADJUSTMENTS
CAUTION: Do not at any time make any adjustment to
lawn mower without first stopping engine and disconnecting
spark plug wire.
CUTTING HEIGHT — An adjusting plate and thumb lever
at each 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. All wheels must be
positioned in relative height of cut positions.
THROTTLE — If adjustment becomes necessary, the throt­
tle control wire assembly can be reset as follows:
1. Loosen, but do not remove, screw securing throttle con­
trol wire assembly at engine.
2. Move throttle control lever on handle to “FAST” pos­
tion.
3. Move lever, to which control wire is fastened at engine,
to full open position and 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 lawn mower.
WHEELS: Wheel bearings are of lifetime Fortiflex. They
require no lubrication.
THROTTLE: Periodically lubricate throttle control lever
and Sirottle 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.
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 as­
sembly 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
a guide. It is extremely important that each cutting edge
receives an equal amount of grinding to prevent an un­
balanced 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 undersirable 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 en­
gine 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 in­
structions.
3. Coat mower’s 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.
USING YOUR MOWER
For best results, do not cut wet grass because it tends to
stick to underside of the mower thus preventing proper dis­
charge 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 nor­
mal 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 por­
tion, then recut at right angles to first direction.
Lawn should be cut in the fall as long as there is growth.
