SAFE OPERATION PRACTICES - WALK BEHIND MOWERS
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 all 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.

ADJUSTMENTS
CAUTION: Do not at any time make any adjustment to lawn
mower without first stopping engine and disconnecting spark
plug wire.
1. CUTTING HEIGHT - This mower can be adjusted for
seven cutting heights from l”to 3”. To change the height,
move the height adjustment lever away from the engine
and forward to lower the cutting height and move to rear
to raise the cutting height. The one lever adjusts all four
wheels at the same time.
ASSEMBLY INSTRUCTIONS
NOTE: This instruction manual covers various models, and
all accessories shown do not necessarily apply to
your model mower.
OPERATION
1. Service engine with gas and oil. See engine manual packed
with lawn mower for complete instructions for care and
maintenance of engine. READ DIRECTIONS CAREFULLY.
2. To disconnect the power to the rear drive wheels so the
mower can be pushed by hand, depress the handle. To
engage the drive wheels, lift the handle.
3. When turning the mower depress the handle and raise the
front wheels, and pivot on the tear wheels. The differen
tial action of the rear axle allows the wheels to turn in
dependently on turns and allows both wheels to drive
when the handle is in the UP position.
START ENGINE
With the throttle control lever conveniently mounted on the
handle, start, fast, slow and stopping of the engine is
conveniently controlled with one lever.
After the engine has been properly fueled and oiled (Refer
to engine operating and maintenance instructions), start
engine in the following manner;
RECOIL STARTER
1. Move throttle control lever to START position.
2. Crank engine. Pull recoil until starter drive engages and
then with a quick firm pull. Do not pull out so far that
rope stops with a jerk as this will cause rope failure. Do
not allow rope and handle to snap back into place.
3. After two or three full firm pulls on recoil, move speed
control to run position or as soon as engine fires.
4. Operate a new engine at intermediate speeds and light
load for the first few hours as you would a new automotive
engine.
5. To stop engine, move speed control lever to stop position.
6. If carburetor needs adjustment to start or for operation,
see “Carburetor Readjustment” section.
NOTE; A brief break-in period is essential to insure
maximum engine life. This consists of running the en
gine at half speed for a period of time required to use
one tank of gasoline. This is necessary on the initial
run only. It is also recommended that the oil be changed
after five (5) hours of operation. This allows for the
removal of impurities which may have accumulated dur
ing the break-in period. Subsequent oil changes should
be made as stated in the engine manual. Always check
oil before using your mower. Be sure crankcase is full.

CUTTING HEIGHTS
2. The position of the upper handle can be changed so the
end of the handle turns down instead of up to place it in
the most comfortable position for the operator.
3. THROTTLE - If adjustment becomes necessary, the
throttle control wire assembly can be reset as follows:
a) Loosen, but do not remove, screw securing throttle
control wire assembly at engine.
b) Move throttle control lever on handle to “FAST”
position.
c) Move lever, to which controLwire 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.
1. ENGINE-Follow engine manual for lubrication instructions.
2. CONTROLS-Lubricate periodically the control assem
blies and conduit and wire with light engine oil for ease
of operation.
3. WHEELS-The front and rear wheels of your unit are ball
bearings and require periodic lubrication with a light
engine oil.
4. PROTECTIVE SHIELD-The pivotpoints on the protective
shield should be lubricated periodically with light oil to
prevent any rust or binding.
5. 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.
CUTTING BLADE
The blade may easily be removed for grinding 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
guide. It is extremely important that each cutting edge re
ceives 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 as
sembled properly and tightened securely.
GRASS CATCHER Model No. 192-003 is available as optional equip
ment for the mower 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 bag material is subject to wear, and should be
checked periodically. Be sure any replacement bag complies with the
mower manufacturer's recommendations.
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.
