& 112-902-033
TRAINING
1. Read the Operating and Service Instruction Manual
carefully. Be thoroughly familiar with the controls and
proper use of the equipment.
2. Never allow children to operate a power mower.
3. Keep the area of operation clear of all persons,
particularly small children, and pets.
PREPARATION
1. Thoroughly inspect the area where the equipment is to
be used and remove all stones, sticks, wire, bones and
other foreign objects.
2. Do not operate equipment when barefoot or wearing
open sandals. Always wear substantial footwear.
3. Check fuel before starting engine. Do not fill gasoline
tank indoors, when engine is running, or while engine
is still hot. Wipe off any spilled gasoline before starting
engine.
4. Disengage self-propelled mechanism or drive clutch on
units so equipped before starting engine (motor).
5. Never attempt to make a wheel height adjustment while
engine (motor) is running.
6. Mow only in daylight or in good artificial light.
7. Never operate equipment in wet grass. Always be sure
of your footing; keep a firm hold on the handle and
walk; never run.
OPERATION
1. Do not change engine governor settings or overspeed
engine.
2. Do not put hands or feet near or under rotating parts.
Keep clear of discharge opening at all times.
3. Stop blade(s) when crossing gravel drive, walks or roads.
4. After striking a foreign object, stop the engine (motor),
remove wire from spark plug, thoroughly inspect the
mower for any damage, and repair the damage before
restarting and operating the mower.
5. If the equipment should start to vibrate abnormally,
stop the engine (motor) and check immediately for the
cause. Vibration is generally a warning of trouble.
6. Stop engine (motor) whenever you leave the equipment,
before cleaning mower housing, and when making any
repairs or inspections.
7. When cleaning, repairing or inspecting, make certain
blade and ail moving parts have stopped. Disconnect
spark plug wire and keep wire away from plug to prevent
accidental starting.
8. Do not run engine (motor) indoors.
9. Shut engine (motor) off and wait until blade comes to a
complete stop before removing grass catcher and/or
unclogging chute.
10. Mow across the face of slopes, never up-and-down.
Exercise extreme caution when changing direction on
slopes. Do not mow excessively steep slopes.
11. Always disconnect electric mowers (line operated)
before cleaning, repairing, or adjusting.
12. Never operate mower without proper guards, plates or
other safety protective devices in place.
13. Keep washout ports and other mower housing service
openings closed when mowing.
MAINTENANCE AND STORAGE
1. Check blade and engine mounting bolts at frequent
intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be sure equip
ment is in safe working condition.
3. Never store equipment with gasoline in the tank inside
of a building where fumes may reach an open flame or
spark. Allow engine to cool before storing in any
enclosure.
4. To reduce fire hazard keep engine free of grass, leaves or
excessive grease.
5. Check grass catcher bags frequently for wear or deterio
ration. Replace with new bags for safety protection.

OPERATION
1. Service engine with gas and oil. See engine manual packed with
lawn mower for complete instructions for the cate and mainte
nance of engine. READ DIRECTIONS CAREFULLY.
2. When ready to start engine, place throttle control lever, on han
dle, in “START” 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 “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.
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 levfer at
each wheel position provides cutting height adjustment. Each adjust
ing 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 to
ward 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 throttle con
trol 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. Moveriever, 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 fortiflex. They require no lubrication.
THROTTLE — Periodically lubricate throttle control lever and
throttle wire assembly with a few drops of l^ht oil (S.A.E. No. 10
or 20) for ease of operation.
ENGINE - Follow Engine Manual for lubrication instructions.
PROTECTIVE SHIELD - The pivot points on the protective shield
should be lubricated periodically with light oil to prevent any rust or
binding.
CHUTE DEFLECTOR - The torsion spring and pivot point should
be lubricated periodically with light oil to prevent any rust or binding.
Deflector must work freely.
MAINTENANCE
CUTTING BLADE - The blade may easily be removed for grind
ing or replacement as follows:
1. Remove bolt and lockwasher holding blade and blade adapter to
engine crankshaft.
2. Remove blade and blade adapter from engine crankshaft.
3. Remove two bolts, lockwashers and nuts holding blade to blade
adapter. (If necessary.)
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 cleaned after
each period of use as grass clippings, leaves, dirt and other matter
will accumulate. This accumulation of grass clippings, etc., is un
desirable as it will invite rust and corrosion and may cause an un
even 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 pro
ceeding instructions.
2. Refer to Engine Manual for correct engine storage instructions.
3. Coat mower’s cutting blade with chassis grease to prevent rust
ing.
4. Place blocks under deck to raise tires clear of floor.
5. 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
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 walk
ing speed is about the right pace for efficient mowing.
The best mowing pattern is one that allows the clippings to dis
charge 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 di
rection.
5 Lawn should be cut in the fall as long as there is growth.
Page 6
GRASS CATCHER Model No. 192-003 is available as optional
equipment for the mowers shown in this manual.
WARNING:
1. The mower should not be operated without the entire grass
catcher or chute deflector in place.
2. The mower should not be operated without the protective
shield on the rear of the deck in place.
NOTE:
Under normal usage the bag material is subject to deterioration and
wear and should be checked for replacement. Be sure that any re
placement bag complies with the original manufacturer's specifica
tion.
For replacement bags, use only factory authorized replacement bag
No. 764-119.
♦ IMPORTANT
After striking a foreign object, stop the engine (motor), remove wire
from spark plug. Throughly inspect the mower for any damage, and
repair the damage before restarting and operating the mower.
