SAFE OPERATION PRACTICES FOR WALK-BEHINO MOWERS
TRAINING
1. Read this owner’s manual carefully in its en
tirety before attempting to assemble or
operate this machine. Be completely familiar
with the controls and the proper use of this
machine before operating it. Keep this manual
in a safe place for future and regular reference
and for ordering replacement parts.
2. Your rotary mower is a precision piece of
power equipment, not a plaything. Therefore,
exercise extreme caution at all times.
3. Never allow children to operate a power
mower. Only persons well acquainted with
these rules of safe operation should be al
lowed to use your mower.
4. Keep the area of operation clear of all per
sons, particularly small children and pets.
Stop engine when they are in the vicinity of
your mower. Although the area of operation
should be completely cleared of foreign ob
jects, an object may have been overlooked
and could be accidently thrown by the mower
in any direction and cause serious personal
injury to the operator or any others allowed In
the area.
PREPARATION
1. Thoroughly inspect the area where the equip
ment is to be used. Remove all stones, sticks,
wire, bones and other foreign objects which
could be picked up and thrown by the mower
in any direction and cause serious personal
injury to the operator or any others allowed in
the area.
2. Do not operate equipment when barefoot or
wearing open sandals. Always wear substan
tial footwear.
3. Do not wear loose fitting clothing that could
get caught on the mower.
4. Check the fuel before starting the engine.
Gasoline is an extremely flammable fuel. Do
not fill the gasoline tank indoors, while the
engine is running, or while the engine is still
hot. Wipe off any spilled gasoline before start
ing the engine as it may cause a fire or explo
sion.
5. Disengage the self-propelled mechanism or
drive clutch on units so equipped before start
ing the engine.
6. The blade control handle is a safety device.
Never attempt to bypass its operation. Doing
so makes the safety device inoperative and
may result in personal injury through contact
with the rotating blade. The blade control han
dle must operate easily in both directions.
7. Never attempt to make a wheel or cutting
height adjustment while the engine is run
ning.
8. Mow only in daylight or in good artificial light.
9. Never operate the equipment in wet grass.
Always be sure of your footing. A slip and fall
can cause serious personal injury. Keep a firm
hold on the handle and walk, never run. 3
OPERATION
1. Do not change the engine governor settings
or overspeed the engine. Excessive engine
speeds are dangerous.
2. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at
all times as the rotating blade can cause in
jury.
3. Stop the blade when crossing gravel drives,
walks or roads.
4. After striking a foreign object, stop the
engine, remove the wire from the spark plug,
and thoroughly inspect the mower for any
damage. Repair the damage before restarting
and operating the mower.
5. If the equipment should start to vibrate abnor
mally, stop the engine and check immediately
for the cause. Vibration is generally a warning
of trouble.
6. Shut the engine off and wait until the blade
comes to a complete stop before removing
the grass catcher or unclogging the chute.
The cutting blade continues to rotate for a few
seconds after the engine is shut off. Never
place any part of the body In the blade area un
til you are sure the blade has stopped rotating.
7. Before cleaning, repairing or inspecting, make
certain the blade and all moving parts have
stopped. Disconnect the spark plug wire, and
keep the wire away from the spark plug to pre
vent accidental starting.
8. Do not run the engine indoors.
9. Mow across the face of slopes, never up-anddown. Exercise extreme caution when chang
ing direction on slopes. Do not mow ex
cessively steep slopes. Always be sure of
your footing. A slip and fall can cause serious
personal Injury.
10. Always disconnect electric mowers (line
operated) before cleaning, repairing or ad
justing.
11. Never operate mower without proper guards,
plates or other safety protective devices in
place.
MAINTENANCE AND STORAGE
1. Check the blade and engine mounting bolts at
frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be
sure the equipment is in safe working condi
tion.
3. Never store the equipment with gasoline in
the tank inside of a building where fumes may
reach an open flame or spark. Allow the
engine to cool before storing in any en
closure.
4. To reduce fire hazard, keep the engine free of
grass, leaves, or excessive grease.
5. Check the grass catcher bag frequently for
wear or deterioration. For safety protection,
replace only with new bag meeting original
equipment specifications.
SAFE OPERATION PR/lCTICES (Continued)
BLADE BRAKE/CLUTCH MAINTENANCE
NOTE: Any required repair work on the blade
brake/clutch should be performed by an author
ized service dealer. If you cannot locate an author
ized service dealer, contact the manufac urer as
set forth on your copy of the Owner’s Regi îtration
Card.
1. The blade brake/clutch hand control is a safe
ty device. Never attempt to bypass it:; opera
tion. Doing so makes the safety de/ice in
operative and may result in personal injury
through contact with the rotating blade. This
hand control must operate freely in both direc
tions.
2. Striking a solid object can cause damage to
the blade brake/clutch or to the engine
crankshaft. Extensive vibration of the mower
during operation is an indication of damage
and the unit should be promptly inspected
and repaired.
3. A leak in the lower engine crankshaft oil seal
could expose the blade brake/clutch friction
pads to excess oil resulting in blade or brake
slippage, which could increase the stopping
time of the blade. Oil collection on the floor
beneath the mower during storage may be an
indication of an oil seal leak. The unit should
be checked by an authorized service dealer.
4. Periodically inspect the inner control cable in
the area where it attaches to the hand control.
If the cable becomes frayed, it could cause
the blade brake/clutch to operate improperly.
Also, be careful to avoid pinching the blade
brake/clutch control cable when using the
folding handle feature (on units so equipped).
This unit is'shipped WITHOUT GAS
OLINE or OIL. After assembly, see
separate engine manual for propor
fuel and engine oil recommenda
tions.
