grass catchers, are in place and working correctly.
General Lawn Mower Safety
The following instructions have been adapted from
the ISO standard 5395.
This cutting machine is capable of amputating hands
and feet and throwing objects. Failure to observe the
following safety instructions could result in serious
injury or death.
Training
• Read the instructions carefully. Be familiar with the
controls and the proper use of the equipment.
• Never allow children or people unfamiliar with these
instructions to use the mower. Local regulations can
restrict the age of the operator.
• Keep in mind that the operator or user is responsible
for accidents or hazards occurring to other people or
their property.
• Understand explanations for all pictograms used on the
lawn mower or in the instructions.
• Before using, always visually inspect to see that the
blades, blade bolts and cutter assembly are not worn or
damaged. Replace worn or damaged blades and bolts
in sets to preserve balance.
Starting
• Disengage all blade and drive clutches and shift into
neutral before starting the engine.
• Do not tilt mower when starting the engine or
switching on the motor, unless the mower has to be
tilted for starting. In this case, do not tilt it more than
absolutely necessary and lift only the part, which is
away from the operator.
• Start the engine or switch on the motor carefully
according to instructions and with feet well away from
the blade(s) and not in front of the discharge chute.
Operation
• Never mow while people, especially children, or pets
are nearby.
• Mow only in daylight or in good artificial light.
3
• Stay alert for holes in the terrain and other hidden
hazards.
– if lawn mower starts to vibrate abnormally (check
immediately).
• Never direct discharge of material towards bystanders.
• Avoid operating the equipment in wet grass, where
feasible.
• Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
• Never pick up or carry a lawn mower while the engine
is running.
• Use extreme caution when reversing or pulling a
pedestrian controlled lawn mower towards you.
• Do not carry passengers.
• Walk, never run.
Slopes:
– Do not mow excessively steep slopes.
– Exercise extreme caution when on slopes.
– Mow across the face of slopes, never up and down
and exercise extreme caution when changing
direction on slopes.
– Always be sure of your footing on slopes.
Use low throttle settings when engaging the
traction–clutch, especially in high gears. Reduce speed on
slopes and in sharp turns to prevent overturning or loss of
control.
Stop the blades if the lawn mower has to be tilted for
transportation when crossing surfaces other than grass and
when transporting the lawn mower to and from the area to
be mowed.
Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
Stop the engine
– whenever you leave the lawn mower.
– before refueling.
– before removing the grass catcher.
– before making height adjustment unless adjustment
can be made from the operator’s position.
Stop the engine and disconnect the spark–plug lead or turn
off and remove key
– before clearing blockages or unclogging chute.
– before checking, cleaning or working on the lawn
mower.
– after striking a foreign object, inspect the lawn
mower for damage and make repairs before
restarting and operating the lawn mower.
Use care when using sulkies, and
– use only approved drawbar hitch points.
– limit loads to those you can safely control.
– do not turn sharply; use care when reversing.
Watch out for traffic when crossing or near roadways.
Before leaving the operator’s position
• disengage the power take–off and lower the
attachments.
• change into neutral and set the parking brake.
• stop the engine and remove the key.
Maintenance and storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Do not use pressure clean equipment on machine.
• Never store the equipment with gasoline in the tank
and inside a building where fumes can reach an open
flame or spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and gasoline storage are free of
grass, leaves, or excessive grease.
• Check the grass catcher frequently and replace if worn
or deteriorated.
• Replace worn or damaged parts for safety.
• Replace faulty silencers.
• If the fuel tank has to be drained, do this out–doors.
• Do not change the engine governor settings or
overspeed the engine. Operating an engine at
excessive speed can increase the hazard of personal
injury.
• On multibladed or multicylinder lawn mowers, take
care as rotating one blade or cylinder may cause others
to rotate.
• When lawn mower is to be parked, stored or left
unattended lower the cutting means unless a positive
mechanical lock is provided.
• Be careful during adjustment of the lawn mower to
prevent entrapment of the fingers between moving
blades and fixed parts of the lawn mower.

Gasoline and Oil
Recommended Gasoline
Use UNLEADED Regular Gasoline suitable for
automotive use (85 pump octane minimum). Leaded
regular gasoline may be used if unleaded regular is not
available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 (6 mm to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle
or on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas–powered
equipment from the truck or trailer and refuel
the equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline
dispenser nozzle.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
Warning
Gasoline is harmful or fatal if swallowed.
Long–term exposure to vapors can cause serious
injury and illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at
all times.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around fuel tank cap and remove the cap. Add
unleaded regular gasoline to fuel tank, until the level is
1/4 to 1/2 inch (6 mm to 13 mm) below the bottom of
the filler neck. This space in the tank allows gasoline
to expand. Do not fill the fuel tank completely full.
3. Install fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Check Engine Oil Level
Before you start the engine and use the machine, check
the oil level in the engine crankcase; refer to Checking Oil
Level, page 22.
