SAFETY PRECAUTIONS

1.6 1.6

TRAINING

Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn

how to stop the mower quickly in an emergency.

Never allow children or people unfamiliar with these instructions to use the mower. Local regulations

may restrict the age of the operator.

Never mow while people, especially children, or pets are nearby.

Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or

their property.

Do not carry passengers.

All drivers should seek and obtain professional and practical instruction. Such instruction should emphasise:

The need for care and concentration when working with this machine.

The need to slow down when making tight turning manoeuvres. Failure to take adequate care can affect

stability leading to loss of control of the machine particularly when operating in transport mode.

Control of a ride-on-machine sliding on a slope will not be regained by 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 the task.

- Lack of awareness of the effect of ground conditions, especially slopes.

- Incorrect load distribution.

PREPARATION

Check that the machine complies with all applicable regulations, including those in force when used on

the public highway.

While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when

barefoot or wearing open sandals. Eye protection should be worn.

Thoroughly inspect the area where the equipment is to be used and remove all objects which can be

thrown by the machine.

Never operate the machine without first checking that the operator platform latching mechanism is fully

engaged and in good working order, refer - ‘OPERATOR PLATFORM LATCHING MECHANISM’.

READ THIS MANUAL BEFORE USING THE T424 MOWER, IT IS ESSENTIAL THAT

OPERATORS STUDY IT FOR THEIR OWN SAFETY.

THE FOLLOWING PRECAUTIONS MUST BE TAKEN TO HELP PREVENT ACCIDENTS.

A CAREFUL OPERATOR WHO USES COMMON SENSE IS THE SAFEST OPERATOR.

SAFETY PRECAUTIONS

PREPARATION Continued.

Ensure that the cutterheads are fully raised with the latches and safety locks engaged in position before

transporting the mower.

Replace faulty silencers.

Check the condition of the tyres and ensure that they are inflated to the correct pressures, refer -

SPECIFICATIONS.

This is particularly important if the machine is to be taken on the public highway.

Check that the mower is in good working order, paying particular attention to the brakes and steering.

Also ensure that the forward/reverse speed control pedals move freely to neutral when released.

Before use, always visually inspect to see that the blades, blade bolts and cutting cylinders are not worn

or damaged. Replace worn or damaged components.

Check the mower hydraulic system, particularly the hydraulic hoses, fittings and hose supports. Worn,

crushed or damaged hoses can burst, with risks to health and damage to the machine and surrounding

turf areas.

After refuelling and adding oil to the hydraulic oil tank ensure that the caps are replaced securely.

Check that all linkages, connections and pivot nuts are secure and that wheel nuts are torqued correctly,

refer - SPECIFICATIONS.

Before operating the machine, ensure that there are no foreign objects or liquids on the platform or ped-

als - ALWAYS KEEP THE OPERATOR PLATFORM CLEAR/CLEAN.

OPERATION

Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect.

Mow only in daylight or in good artificial light.

Before attempting to start the engine, engage the parking brake, disengage the cutterhead drive system

and ensure that the forward/reverse speed controls are in the neutral position.

Never operate the machine without first checking that the operator platform latching mechanism is fully

engaged and in good working order, refer - OPERATOR PLATFORM LATCHING MECHANISM.

Stored energy devices are charged when the outer wing units are in the transport position. Always oper-

ate the relevant lift controls to provide hydraulic support for the wing units suspensions before attempt-

ing to release the transport latches.

SAFETY PRECAUTIONS

OPERATION Continued.

Do not use on a slope of more than 19 degrees. Care should be taken when using the mower on any slope

where ground conditions are such that there may be a risk of the mower rolling over. The requirements

of SI 1998 No. 2306 “Provision and Use of Work Equipment Regulations” should be considered.

R.O.P.S (Roll Over Protective Structures) are available, refer to INTRODUCTION - Optional Extras.

Stability angles given are maximum figures and are for guidance only. Particular conditions such as wet

grass or uneven ground may not permit safe operation on the slope limits stated.

Remember there is no such thing as a "safe" slope. Travel on grass slopes requires particular care. To

guard against overturning or loss of traction when travelling or mowing on a slope:

- Exercise extreme care when changing direction on a slope.

- Do not stop or start suddenly.

- Engage drive slowly.

- Keep machine speed low.

- Avoid tight turns.

- Stay alert for humps, hollows and other hidden hazards.

- Keep away from sharp inclines and steep drops.

- A thorough risk assessment should be carried out by a competent

person before travelling or mowing on a slope.

Never park on a slope.

SAFETY PRECAUTIONS

1.9 1.9

OPERATION Continued.

Watch out for traffic when crossing or near roadways.

Use extreme caution when reversing.

Disengage the cutterhead drive system before crossing surfaces other than grass.

When using the machine, never direct the discharge of material towards bystanders or allow anyone

near the machine while in operation.

Never operate the mower with defective guards, shields or without safety protective devices in place

and in good working order.

Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive

speed may increase the risk of personal injury.

Before leaving the operator's position:

- Disengage the drive to the cutterheads.

- Lift cutterheads to the transport position and securely lock the safety latches

or alternatively lower cutterheads to the ground.

- Change into neutral and set the parking brake.

- Stop the engine and remove the ignition key.

Engage the parking brake, disengage the drive to the cutterheads, stop the engine and remove ignition

key :

- Before releasing blockages.

- Before checking, cleaning or working on the mower.

- After striking a foreign object. Inspect the mower for damage and make

repairs before restarting and operating the equipment.

- If the machine starts to vibrate abnormally ( check immediately ).

- Before refuelling.

- Before making cutterhead adjustments.

Disengage the drive to the cutterheads when transporting or not in use.

Reduce the throttle setting during engine run - out.

Never work on the mower when the engine is running.

Always keep feet and hands well away from the cutting cylinders when making adjustments.

Never operate the mower without first checking that the operator platform is securely latched.
