SAFETY INSTRUCTIONS
•
•
If the equipment should start to vibrate abnormally, stop the engine and
check immediately for the cause. Vibration is generally a warning of trouble.
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.
Shut the engine off and wait until the blade comes to a complete stop before
removing the grass Bagger or unclogging the chute. The cutting blade
continues to rotate for a few seconds after the blade control is released.
Never place any part of the body in the blade area until you are sure the
blade has stopped rotating.
•
Keep children out of the mowing area and under watchful care of a
responsible adult other than the operator.
•
Never operate mower without proper trail shield, discharge cover, grass
Bagger, blade control handle or other safety protective devices in place and
working. Never operate mower with damaged safety devices. Failure to do so
can result in personal injury.
•
•
Be alert and turn mower off if a child enters the area.
Before and while moving backwards, look behind and down for small
children.
•
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.
•
•
Muffler and engine become hot and can cause a burn. Do not touch.
Never attempt to make a wheel or cutting height adjustment while the
engine is running.
•
•
Keep children away from hot or running engines. They can suffer burns from
a hot muffler.
•
•
Only use parts and accessories made for this machine by the manufacturer as
listed in the Parts pages of this Operator’s Manual. Failure to do so can result
in personal injury.
Never allow children under 14 years of age to operate this machine. Children
14 and over should read and understand the instructions and safe operation
practices in this manual and on the machine and be trained and supervised
by an adult.
When starting engine, pull cord slowly until resistance is felt, then pull
rapidly. Rapid retraction of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go. Broken bones, fractures, bruises or
sprains could result.
SERVICE
Safe Handling of Gasoline:
•
If situations occur which are not covered in this manual, use care and good
judgement.
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. Wash your skin and change clothes immediately.
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. The machine is heavy and can
speed up when going downhill. Be prepared to maintain control of the machine.
If you feel uneasy on a slope, do not mow it. For your safety, use the slope gauge
included as part of this manual to measure slopes before operating this machine on
a sloped or hilly area. If the slope is greater than 15 degrees, do not mow it.
•
•
Use only an approved gasoline container.
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.
•
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.
Do:
•
Mow across the face of slopes; never up and down to avoid loss of control.
•
Exercise extreme caution when changing direction on slopes; turn uphill not
down.
•
•
•
•
•
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.
•
•
Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you
to slip or trip. Tall grass can hide obstacles.
Extinguish all cigarettes, cigars, pipes and other sources
of ignition.
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 three (3)
seconds.
Never fuel machine indoors because flammable vapors will accumulate in
the area.
Never remove gas cap or add fuel while engine is hot or running. Allow
engine to cool at least two minutes before refueling.
Do Not:
•
Never over-fill fuel tank. To allow for expansion of the fuel, do not fill above
the bottom of the fuel tank neck.
Do not mow near drop-offs, ditches or embankments, because you could
lose your footing or balance.
•
•
Replace gasoline cap and tighten securely.
•
•
Do not mow slopes greater than 15 degrees as shown on the slope guide.
Do not mow on wet grass. Unstable footing could cause slipping.
If gasoline is spilled, wipe it off the engine and equipment. Move machine to
another area. Wait 5 minutes before starting engine.

OFF-SEASON STORAGE
WARNING
Never store lawn mower with fuel in tank indoors or in poorly ventilated
areas where fuel fumes may reach an open flame, spark, or pilot light as on
a furnace, water heater, clothes dryer, or gas appliance.
Preparing The Engine
Preparing The Lawn Mower
For engines stored over 30 days:
•
Clean and lubricate mower thoroughly as described in the lubrication
instructions.
•
To prevent gum from forming in fuel system or on carburetor parts, run
engine until it stops from lack of fuel or add a gasoline additive to the gas
in the tank. If you use a gas additive, run the engine for several minutes to
circulate the additive through the carburetor.
•
•
Do not use a pressure washer or garden hose to clean your unit.
Coat mower’s cutting blade with chassis grease to prevent rusting.
•
•
An oil change is not required but if you desire to change the oil then change
while the engine is warm.
WARNING
When handling the cutting blade, protect your hands with a pair of heavy
gloves or use a heavy rag to hold the blade.
Clean engine of surface debris.
•
•
Refer to Preparing the Engine for correct engine storage instructions.
Store mower in a dry, clean area. Do not store next to corrosive materials,
such as fertilizer.
When storing any type of power equipment in a poorly ventilated or metal storage
shed, care should be taken to rust-proof the equipment. Using a light oil or silicone,
coat the equipment, especially cables and all moving parts of your lawn mower
before storage.
Battery
•
The battery must be stored with a full charge. Extended storage of a
discharged battery will reduce life and capacity of the battery. For optimal
battery life, charge the battery once per month while in storage.
•
Remove electric start push key and keep in a safe place out of the reach of
children.
