manuals applicable to the machine.
• Remove and store correctly
1. Batteries
2. Fuel
3. Engine coolant
4. Oils
• Read the Technical Manual before you begin to disassemble the machine. Plan the disassembly, give
attention to parts that are in a state of mechanical pressure or contain stored energy e.g springs.
• Items that continue to have a service life must be separated and returned to the local dealer.
• Items that are worn must be separated into the material groups and removed according to the agencies
for the recycled materials that are available. Common examples.
• Steel
• Non ferrous metals
• Aluminium
• Brass
• Copper
• Plastic materials
• Identified
• Can be recycled
• Can not be recycled
• Not identified
• Rubber
• Electrical and Electronic Comp onents
• Some parts are not easily separated e.g Hydraulic hose. These materials must be added to the
“General discarded materials” area.
• Do not burn discarded materials.

3.1 HOW TO OPERATE SAFELY _____________________________________________
WARNING
EQUIPMENT THAT IS NOT OPERA TED CORRECTL Y OR BY PERSONNEL WITHOUT TRAINING CAN
BE DANGEROUS.
Know the location and c orrect use of all controls. Befor e any use of the machi ne, personnel w ithout training
must receive instruction from personnel with experience in the machines operation.
3.1.1 Safe operation
a) Read the instructions carefully. Know the
controls and the correct use of the
equipment;
b) Children or persons who do not understand
these instructions must not use the
machine. The Local regulations will set the
age of the operator;
c) Never use a machine near persons,
including children or animals;
d) Remember that the operator or user is
responsible for accidents or hazards that
occur to other persons or their property.
e) Do not carry passengers;
f) All drivers must get instruction. That
instruction must include:
- A need for careful attention when you use a
“ride-on” class machine.
- The loss of traction on slopes or in a
condition of decreased traction, is not
always corrected by an application of the
brakes.
Reasons for the loss of control.
i) Not enough wheel grip;
ii) Driving at more than the safe speed for the
conditions
iii) You over brake or brake suddenly.
iv) The type of machine is wrong for the job;
v) No attention given to the ground conditions
or operating slopes;
vi) Incorrect hitch and load distribution.
3.1.2 Preparation
a) When you operate the machine, always
wear strong footwear and long trousers. Do
not operate the equipment without the
correct footwear.
b) Inspect the area you are to cut. Objects or
any particles in the area are a safety risk.
Remove these objects. These objects can
damage the blades or cause injury to any
person near.
c) WARNING - Diesel and Petrol are
flammable.
- Store in clean applicable metal containers.
- Refuel outdoors only and do not smoke
when you add fuel;
- Refuel the machine before you start the
engine. When the engine is hot, do not
remove the fuel tank cap or add fuel to the
tank.
- If any fuel spills, do not try to start the
engine, but move the machine away from
the area. Until the fuel vapors have gone
keep any supply of ignition at a distance.
- Replace all fuel tank and container caps
correctly;
d) Replace any damaged or broken silencers.
e) Visually inspect the machine use. Check
the blades, blade bolts and the deck
assembly for wear or damage. Replace all
the blades in a group to keep the balance;
f) On those machines with many blades, be
careful when you rotate one blade, it can
cause other blades to rotate.
3.1.3 Operation
a) Do not operate the engine in a closed
space. The gas Carbon Monoxide is part of
the exhaust gas mix. In a closed space this
gas can reach dangerous levels
b) Use a mower only in daylight or in good
artificial light;
c) Before you start the engine, disengage all
blade attachment clutches and shift into
neutral;
d) Do not use on slopes of more than the
recommended angle;
NOTE The recommended angle is calculated as
shown in BS EN ISO 5395-3:2013 clause
4.6.1, 4.6.2, 4.6.3.
en-7
3 SAFETY
e) Remember there is no safe slope. Operate
with caution on grass slopes.
To guard against a turn over
- Do not stop or start suddenly when you
operate on a slope.
- To operate on a down slope, prevent sharp
movements on the controls and always
keep the machine in gear.
- Go slowly when you operate on slopes and
when you make tight turns;
- Look for any changes in the cutting surface
that can change the mowers balance.
- Never use the mower to move across a
slope on a diagonal line. Unless the
machine is for this purpose;
f) When you pull a load or use accessories,
be careful.
- Use only approved drawbars;
- Any load must not change your full control
of the machine.
- Do not turn suddenly. Be careful when you
move in a reverse direction;
- Use the counterweight or wheel weights
recommended in the instruction handbook;
g) Be careful of those around you and the
users of the road when you move across or
near roadways;
h) Stop the blades before you move across
any surface different from grass;
i) Do not allow the deck outlets to point at
other persons. Do not allow persons near a
machine that you operate.
j) Do not operate the machine with damaged
guards or without safety devices in
position;
k) Do not change the engine governor
settings or operate at more than the
specified engine turns. If you operate the
engine at more than the suppliers set
speed, you increase the hazard of personal
injury;
l) When you leave the position for operation,
disengage the drive and lower the
attachments to the ground.
- Engage neutral and set the parking brake;
- Stop the engine and remove the key;
m) Before you check, clean or work on the
machine.
Disengage the drive to the attachments,
stop the engine and remove the ignition
key:
- When you hit an object, inspect the
machine for damage and make the repairs
before you restart and operate the
equipment;
- If the machine starts to make a sound that
is not normal or begins to cause vibration,
check immediately;
n) When the machine is not in operation or
during transport. Disengage the drive to the
attachments.
Before you refuel or you mak e height
adjustment , un l es s t he adj ustment is made
with the operator in the seat. Stop the
engine and disengage drive to
attachments.
Decrease the throttle setting during the
engine “run-out”. If the engine has a fuel
valve, turn the fuel valve to the OFF
position at the end of operation.
3.1.4 Maintenance and storage
a) Keep all nuts, bolts and screws tight to
make sure the equipment is in safe work
condition;
b) Do not store the equipment with fuel in the
tank. The Fuel vapour can become a
danger in closed spaces.
c) When you store in a closed space, allow
the engine to become cool first;
d) Replace worn or damaged parts for safety;
e) If the fuel tank is drained, drain in an area
with good ventilation.
and:
a) On those machines with many blades, be
careful when you rotate one blade, it can
cause other blades to rotate.;
b) When the machine is parked for an
extended period or put into storage, lower
the cutting device unless a positive
mechanical lock is used.
