Safety
Safe Operation Practices for
Ride-on (riding) Rotary
Lawnmower Machines
Training
1. Read the instructions carefully. Be familiar with
the controls and the proper use of the equipment.
2. Never allow children or people unfamiliar with
these instructions to use the lawnmower. Local
regulations may restrict the age of the operator.
3. Never mow while people, especially children, or
pets are nearby.
4. Keep in mind that the operator or user is
responsible for accidents or hazards occurring to
other people or their property.
5. Do not carry passengers.
6. All drivers should seek and obtain professional
and practical instruction. Such instruction should
emphasize:
• the need for care and concentration when
working with ride-on machines;
• control of a ride-on machine sliding on a
slope will not be regained by the application
of the brake. The main reasons for loss of
control are:
insufficient wheel grip;
being driven too fast;
inadequate braking;
the type of machine is unsuitable for its
task;
lack of awareness of the effects of
ground conditions, especially slopes;
incorrect hitching and load distribution.
Preparation
1. While mowing, always wear substantial
footwear and long trousers. Do not operate the
equipment when barefoot or wearing open
sandals.
2. Thoroughly inspect the area where the
equipment is to be used and remove all objects
which may be thrown by the machine.
3. WARNING – Petrol is highly flammable.
• Store fuel in containers specifically
designed for this purpose.
• Refuel outdoors only and do not smoke
while refuelling.
• Add fuel before starting the engine. Never
remove the cap of the fuel tank or add
petrol while the engine is running or when
the engine is hot.
• If petrol is spilled, do not attempt to start
the engine but move the machine away
from the are of spillage and avoid creating
any source of ignition until petrol vapors
have dissipated.
• Replace all fuel tanks and container caps
securely.
4. Replace faulty silencers.
5. 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.
6. On multi–bladed machines, take care as rotating
one blade can cause other blades to rotate.
Safety
3
Operation
1. Do not operate the engine in a confined space
where dangerous carbon monoxide fumes can
collect.
2. Mow only in daylight or in good artificial light.
3. Before attempting to start the engine, disengage
all blade attachment clutches and shift into
neutral.
4. Do not use on slopes of more than:
• Never mow side hills over 5
• Never mow uphill over 10
• Never mow downhill over 15
Note: Slope angle is calculated as in
5.4.2.3.2.
5. Remember there is no such thing as a “safe”
slope. Travel on grass slopes requires particular
care. To guard against overturning:
• do not stop or start suddenly when going up
or downhill;
• engage clutch slowly, always keep machine
in gear, especially when travelling
downhill;
• machine speeds should be kept low on
slopes and during tight turns;
• stay alert for bumps and hollows and other
hidden hazards;
• never mow across the face of the slope,
unless the lawnmower is designed for this
purpose.
6. Use care when pulling loads or using heavy
equipment.
• Use only approved drawbar hitch points.
• Limit loads to those you can safely control.
• Do not turn sharply. Use care when
reversing.
• Use counterweight(s) or wheel weights
when suggested in the instruction
handbook.
7. Watch out for traffic when crossing or near
roadways.
8. Stop the blades rotating before crossing surfaces
other than grass.
9. When using any attachments, never direct
discharge of material toward bystanders nor
allow anyone near the machine while in
operation.
10. Never operate the lawnmower with defective
guards, shields or without safety protective
devices in place.
11. Do not change the engine governor settings or
overspeed the engine. Operating the engine at
excessive speeds may increase the hazard of
personal injury.
12. 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.
13. Disengage drive to attachments, stop the engine,
and disconnect the spark plug wire(s) or remove
the ignition key
• before cleaning blockages or unclogging
chute;
• before checking, cleaning or working on the
lawnmower;
• after striking a foreign object. Inspect the
lawnmower for damage and make repairs
before restarting and operating the
equipment;
• if the machine starts to vibrate abnormally
(check immediately).
14. Disengage drive to attachments when
transporting or not in use.
Safety
4
15. Stop the engine and disengage drive to
attachment
• before refuelling;
• before removing the grass catcher;
• before making height adjustment unless
adjustment can be made from the operator’s
position.
16. Reduce the throttle setting during engine run-out
and, if the engine is provided with a shut-off
valve, turn the fuel off at the conclusion of
mowing.
Maintenance and storage
1. Keep all nuts, bolts and screws tight to be sure
the equipment is in safe working condition.
2. Never store the equipment with petrol in the tank
inside a building where fumes may reach an
open flame or spark.
3. Allow the engine to cool before storing in any
enclosure.
4. To reduce the fire hazard, keep the engine,
silencer, battery compartment and petrol storage
area free of grass, leaves, or excessive grease.
5. Check the grass catcher frequently for wear or
deterioration.
6. Replace worn or damaged parts for safety.
7. If the fuel tank has to be drained, this should be
done outdoors.
8. On multi-bladed machines, take care as rotating
one blade can cause other blades to rotate.
9. When machine is to be parked, stored or left
unattended, lower the cutting means unless a
positive mechanical lock is used.

Check Engine Oil
The engine is shipped with 4 pints of oil in the
crankcase; however, oil level must be checked before
and after the engine is first started. Check oil level;
refer to Checking Oil Level, page 23.
Check Hydraulic System Fluid
The hydraulic system is shipped with approximately
5 quarts of 10W–30 engine oil; however, oil level
must be checked before the engine is first started.
Check oil level; refer to Check Hydraulic System
Fluid, page 33.
14
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.
POTENTIAL HAZARD
• In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
• A fire or explosion from gasoline can burn
you, others, and cause property damage.
HOW TO AVOID THE HAZARD
• Use a funnel and 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.
Stabilizer/Conditioner
Add the correct amount of gas stabilizer/conditioner
to the gas.
• Keeps gasoline fresh during storage
• Cleans the engine while it runs
• Eliminates gum-like buildup in the fuel system,
which causes hard starting
IMPORTANT: Never use fuel additives
containing methanol or ethanol.
Filling the Fuel Tank
1. Shut the engine off.
2. Clean around the fuel tank cap and remove the
cap. Use a funnel and add unleaded regular
gasoline to the 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 the 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 23.
