Safe Handling Of Gasoline
1. To avoid personal injury or property damage use extreme
care in handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Serious
personal injury can occur when gasoline is spilled on
yourself or your clothes which can ignite.
2. Wash your skin and change clothes immediately.
3. Use only an approved gasoline container.
4. Never fill containers inside a vehicle or on a truck or
trailer bed with a plastic liner. Always place containers on
the ground away from your vehicle before filling.
5. If possible, remove gas-powered equipment from the
truck or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dispenser
nozzle.
6. Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.
7. Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
Slope Operation
Slopes are a major factor related to slip and fall accidents
which can result in severe injury. Operation on slopes
requires extra caution. If you feel uneasy on a slope, do not
mow it. Before operating this unit on a slope or hilly area, use
the slope gauge on page 6 to measure slopes. If the slope is
greater than 15 degrees, do not mow it.
Do:
1. Mow across the face of slopes; never up and down.
Exercise extreme caution when changing direction on
slopes.
2. Watch for holes, ruts, rocks, hidden objects, or bumps
which can cause you to slip or trip. Tall grass can hide
obstacles.
3. Always be sure of your footing. A slip and fall can cause
serious personal injury. If you feel you are losing your
balance, release the blade control handle immediately,
and the blade will stop rotating within 3 seconds.
8. Never fuel machine indoors because flammable vapors
will accumulate in the area.
9. Never remove gas cap or add fuel while the engine is hot
or running. Allow engine to cool at least two minutes
before refueling.
10. Never over fill fuel tank. Fill tank to no more than ½ inch
below bottom of filler neck to provide space for fuel
expansion.
11. Replace gasoline cap and tighten securely.
12. If gasoline is spilled, wipe it off the engine and
equipment. Move unit to another area. Wait 5 minutes
before starting the engine.
Do Not:
1. Do not mow near drop-offs, ditches or embankments,
you could lose your footing or balance.
2. Do not mow slopes greater than 15 degrees as shown on
the slope gauge.
3. Do not mow on wet grass. Unstable footing could cause
slipping.
13. Never store the machine or fuel container inside where
there is an open flame, spark or pilot light as on a water
heater, space heater, furnace, clothes dryer or other gas
appliances.
14. To reduce fire hazard, keep mower free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
Children
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the
mower and the mowing activity. They do not understand the
dangers. Never assume that children will remain where you
last saw them.
15. Allow a mower to cool at least 5 minutes before storing.
General Service
1. Keep children out of the mowing area and under the
watchful care of a responsible adult other than the
operator.
2. Be alert and turn mower off if a child enters the area.
3. Before and while moving backwards, look behind and
down for small children.
4. Use extreme care when approaching blind corners,
doorways, shrubs, trees, or other objects that may
obscure your vision of a child who may run into the
mower.
5. Keep children away from hot or running engines. They
can suffer burns from a hot muffler.
1. Never run an engine indoors or in a poorly ventilated
area. Engine exhaust contains carbon monoxide, an
odorless and deadly gas.
2. Before cleaning, repairing, or inspecting, make certain
the blade and all moving parts have stopped. Disconnect
the spark plug wire and ground against the engine to
prevent unintended starting.
3. Check the blade and engine mounting bolts at frequent
intervals for proper tightness. Also, visually inspect blade
for damage (e.g., bent, cracked, worn) Replace blade
with the original equipment manufacture’s (O.E.M.) blade

6. Never tamper with safety devices. Check their proper
operation regularly.
10. Do not change the engine governor setting or overspeed
the engine. The governor controls the maximum safe
operating speed of the engine.
11. Maintain or replace safety and instruction labels, as
necessary.
12. Observe proper disposal laws and regulations. Improper
disposal of fluids and materials can harm the
environment.
7. After striking a foreign object, stop the engine, disconnect
the spark plug wire and ground against the engine.
Thoroughly inspect the mower for any damage. Repair
the damage before starting and operating the mower.
8. Never attempt to make a wheel or cutting height
adjustment while the engine is running.
9. Grass catcher components, discharge cover, and trail
shield are subject to wear and damage which could

Using Your Rotary Mower
•
Be sure that lawn is clear of stones, sticks, wire, or
other objects which could damage lawn mower or
engine. Such objects could be accidently thrown by
the mower in any direction and cause serious
personal injury to the operator and others.
For best results, do not cut wet grass because it
tends to stick to the underside of the mower,
preventing proper discharge of grass clippings, and
could cause you to slip and fall. New grass, thick
grass or wet grass may require a narrower cut.
Speed of the mower should be adjusted to the
condition of the lawn.
Adjusting Cutting Height
•
Your mower was shipped at the highest cutting
height. For best results in mowing, keep the cutting
height position high until it is determined which
height is best for your lawn.
•
•
Refer to height adjustments section of this manual
on page 10 for instruction on how to adjust the
cutting height and the handle height.
Before Starting
•
For a healthier lawn, always cut off one-third or less
of the total length of grass. Lawn should be mowed
in the fall season as long as there is growth.
•
Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug wire
(inside the rubber boot) is fastened securely over
the metal tip on the spark plug.
WARNING: If your mower strikes a foreign
object, stop the engine. Remove wire from
spark plug, thoroughly inspect the mower for
any damage, and repair the damage before
restarting and operating the mower.

washers or garden hose to clean your unit. It may
cause damage to electric components, spindles,
pulleys, bearings or the engine. The use of water will
shorten life and reduce serviceability of the equipment.
•
•
When sharpening the 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, may damage the
mower and/or cause personal injury.
The blade can be tested by balancing it on a round
shaft screwdriver. Remove metal from the heavy
side until it balances evenly. It is recommended that
the blade always be removed from the adapter for
the best test of balance
