IMPORTANT
SAFE OPERATION PRACTICES FOR WALK-BEHIND MOWERS
TRAININO
1. Read the Operating and Service Instruction Man
ual carefully. Be thoroughly familiar with the con
trols and the 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 the fuel before starting the engine. Do not
fill the gasoline tank indoors, when the engine is
running, or while the engine is still hot. Wipe off
any spilled gasoline before starting the engine.
4. Disengage the self-propelled mechanism or drive
clutch on units so equipped before starting the en
gine.
5. Never attempt to make a wheel adjustment while
the engine is running.
6. Mow only in daylight or in good artificial light.
7. Never operate the equipment in wet grass. Al
ways be sure of your footing; keep a firm hold on
the handle and walk, never run.
5. If the equipment should start to vibrate abnormal
ly, stop the engine and check immediately
for the cause. Vibration is generally a warning of
trouble.
6. Stop the engine whenever you leave the equip
ment, before cleaning the mower housing, and
when making any repairs or inspections.
7. When cleaning, repairing or inspecting, make cer
tain the blade and all moving parts have stopped.
Disconnect the spark plug wire, and keep the wire
away from the plug to prevent accidental starting.
8. Do not run the engine indoors.
9. Shut the engine off and wait until the blade comes
to a complete stop before removing the grass
catcher or unclogging chute.
10. Mow across the face of slopes, never up-anddown. 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
OPERATION
1. Do not change the engine governor settings or
overspeed the engine.
2. Do not put hands or feet near or under rotating
parts. Keep clear of the discharge opening at all
times.
3. Stop the blade(s) when crossing gravel drive,
walks or roads.
4. After striking a foreign object, stop the engine,
remove the wire from the spark plug, thor
oughly inspect the mower for any damage, and
repair the damage before restarting and operat
ing the mower.
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 condition.
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 enclosure.
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. Replace with new bag for safety
protection.
CAUTION
OPERATION
Please note that the chute deflector on
your mower is in an upright position. It
is held in that position by a shipping
block. This block is used for shipping
purposes only. It must be removed and
discarded before your mower is put
into operation.

ASSEMBLY
For shipping purposes, the wheels on your mower are
generally set in the upper mounting holes. Relocating
the wheels to the second holes from the bottom will
give better mowing results in most cases. When chang
ing wheel positions, be sure Belleville washers are
assembled properly. (See cutting height instructions.)
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 Di
rections carefully.
2. When ready to start engine, place throttle control
lever on handle in "START" position and start en
gine in accordance with instructions in engine man
ual. 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.
Two cycle engines are constant speed engines. No
throttle control is required. The
engine is stopped by moving
the spark plug shorting lever
against the tip of the spark
plug. Be sure this is moved

away before starting the
engine.
Your new mower is shipped preassembled with the
exception of the handle.
1. Remove lawn mower and all parts from the carton.
Make certain that all loose parts and literature have
been removed before the carton is discarded.
2. If mower is equipped with throttle control extend
throttle control assembly which is attached to en
gine at the rear of the mower and place on the floor.
CAUTION: Do not bend or kink control wires.
NOTE
Two cycle engine are constant speed
engines—some engines have manual
friction control on the engine. These en
gines require no remote throttle con
trol.
3. Assemble the upper and lower handle parts with
cap screws and locknuts provided in parts bag. On
mower with throttle control, use the longer (yellow)
screw to attach throttle control.
4. Floles at the bottom of the lower handle are to be
fitted over studs located in front of each rear wheel
mounting 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 ex
cessively wet.
ADJUSTMENTS
CAUTION
Do not at any time make any adjust
ment to lawn mower without first stop
ping engine and disconnecting spark
plug wire.
CUTTING HEIGHT
Adjustment may be made by removing and moving
wheel studs to desired position. Cutting heights 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 (OPTIONAL)
5. Secure throttle control wire to lower right handle
with cable clips.
6. Check ALL nuts and bolts for correct tightness.
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.
