2.3 GUIDELINES FOR THE DISPOSAL OF SCRAP PRODUCTS _________________

2.3.1 DURING SERVICE LIFE _______________________________________________

All the used fluids and parts must be controlled as hazardous materials material. Recommended procedures must be

followed for their safe removal.

If a fluid leak occurs, contain the spill to make sure that the leak does not flow into the ground or drainage system.

Follow the regulations in force to make sure that leaks are controlled.

The maintenance procedures in this manual make sure that the damage that the machine can cause in the local

environment is controlled.

When the machine completes its full service life, the following actions must be taken.

• 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

SAFETY 3

3.1 HOW TO OPERATE SAFELY _____________________________________________

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.

WARNING

EQUIPMENT THAT IS NOT OPERATED CORRECTLY OR BY PERSONNEL WITHOUT TRAINING CAN

BE DANGEROUS.

Know the location and correct use of all controls. Before any use of the machine, personnel without training

must receive instruction from personnel with experience in the machines operation.

en-8

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 make height

adjustment, unless the adjustment 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.
