Safe Operating Practices
Training
Read this manual and other training material
carefully.
Be familiar with the controls, safety signs,
and the proper use of the equipment.
If the operator or mechanic can not read the
language used in this manual, it is the
owner's responsibility to explain this material
to them.
All operators and mechanics should seek
and obtain professional and practical
instruction.
The owner is responsible for training the
users.
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 effect of
ground conditions, especially slopes
Incorrect hitching and load distribution

Page 1-2 Safe Operating Practices

Add fuel before starting the engine.
Never remove the cap of the fuel tank or
add fuel while the engine is running or
when the engine is hot.
Refuel outdoors only and do not smoke
while refueling.
If fuel is spilled, do not attempt to start the
engine but move the machine away from
the area of spillage and avoid creating any
source of ignition until petrol vapours have
dissipated;
Replace all fuel tanks and container caps
securely.
Check that operator's presence controls,
safety switches and shields are attached and
functioning properly.
Do not operate unless they are functioning
properly.
If the brake operation is faulty, be sure to
adjust or repair them before operating the
machine.
Replace faulty mufflers.
On multi-cylinder/multi-reel machines, take
care as rotating one cylinder/reel can cause
other cylinders/reels to rotate.
Operation
Do not operate the machine under the
influence of alcohol or drugs.
Do not operate the engine in a confined
space where dangerous carbon monoxide
fumes can collect.
Be sure all drives and shift are in neutral and
parking brake is engaged before starting
engine.
Only start engine from the operator's
position.
Use seat belts if provided.
Do not change the engine governor settings
or overspeed the engine.
Operating the engine at excessive speed
may increase the hazard of personal injury.
Never operate the machine with damaged
guards, shields, or without safety protective
devices in place.
Be sure all interlocks are attached, adjusted
properly, and functioning properly.
Keep hands and feet away from the rotating
parts.

turns and crossing roads and sidewalks.
Use care when approaching blind corners,
shrubs, trees, or other objects that may
obscure vision.
Do not take your eyes off the road ahead.
Do not operate the machine with no hands.
Keep a folding ROPS in the raised and
locked position and use the seat belt when
operating the machine.
Lower a folding ROPS temporarily only when
absolutely necessary.
Do not wear the seat belt when folded down.
There is no rollover protection when a folding
ROPS is in the down position.
Remember there is no such thing as a safe
slope.
Travel on grass slopes requires particular
care.
To guard against overturning, follow these
instructions.
Do not stop or start suddenly when going
up or downhill.
Engage clutch slowly, always keep
machine in gear, especially when traveling
downhill.
Machine speeds should be kept low on
slopes and during turns.
Stay alert for humps and hollows and
other hidden hazards.
Never use the machine on a slope with an
angle of gradient that is greater than that
specified or in a place where there is a
danger of the machine slipping.

Safety
Page 1-4 Safe Operating Practices

When checking the hydraulic circuit for
pinhole leaks or oil leakage from nozzles, do
not use your hands.
Use items such as paper or corrugated
cardboard to find leakage points.
Be extremely careful with high-pressure oil
as it may pierce your skin, resulting in an
injury.
If fluid is injected into the skin it must be
surgically removed within a few hours by a
doctor familiar with this form of injury or
gangrene may result.
Use care when checking the cylinders/reels
and bed knives.
Wear gloves and use caution when servicing
them.
Be careful during adjustment of the machine
to prevent entrapment of the fingers between
moving blades and fixed parts of the
machine.
On multi-cylinder/multi-reel machines, take
care as rotating one cylinder/reel can cause
other cylinders/reels to rotate.
Check the grass catcher frequently for wear
or deterioration.
Charge batteries in an open well ventilated
area, away from spark and flames.
Unplug charger before connecting or
disconnecting from battery.
Wear protective clothing and use insulated
tools.
If the fuel tank has to be drained, do this
outdoors.
Storage
When machine is to be parked, stored, or left
unattended, lower the cutting unit(s) and/or
attachment(s) unless a positive mechanical
lock is provided.
Allow the engine to cool before storing in any
enclosure.
Only cover the machine with a sheet after
hot parts have sufficiently cooled down.
Never store the equipment with fuel in the
tank inside a building where fumes may
reach an open flame or spark.
If the engine is provided with a shut-off
valve, shut off valve while storing or
transporting.
Do not store fuel near flames.
