SAFETY PRECAUTIONS  
1.6  
READ THIS MANUAL BEFORE USING THE TRACTOR, IT IS ESSENTIAL THAT OPER-  
ATORS 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.  
TRAINING  
Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn  
how to stop the tractor quickly in an emergency.  
Never allow children or people unfamiliar with these instructions to use the garden tractor and powered  
sweeper collector. 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 garden tractor and powered sweeper collector.  
-
-
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 tractor.  
-
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  
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.

SAFETY PRECAUTIONS  
1.7  
PREPARATION  
Continued.  
Warning - petrol is highly flammable:  
- Store fuel in containers specially designed for this purpose.  
- Refuel outdoors only and do not smoke while refuelling.  
- Add fuel before starting the engine. Never remove the cap from the tank or add petrol while the  
engine is running or when the engine is hot. Allow the engine to cool for at least two minutes  
before refuelling.  
- Do not attempt to start the engine if petrol is spilled or a smell of petrol is present. Move the  
machine away from the area of the spillage and avoid creating any source of ignition until the  
petrol vapours have dissipated.  
- Always use fresh fuel. Stale fuel can block the carburettor and cause leakage.  
- Replace fuel tank and oil tank caps securely.  
Ensure that the cutterdeck is fully raised before transporting the tractor.  
Replace faulty silencers.  
Check the condition of the tyres and ensure that they are inflated to the correct pressures.  
Check that the garden tractor and powered sweeper collector are in good working order, paying particular  
attention to the brakes and steering. Also ensure that the forward/reverse travel control pedal moves freely  
to neutral when released.  
Before use, always visually inspect to see that the blades, blade bolts and cutterdeck assembly are not worn  
or damaged. Replace worn or damaged components.  
Check that all linkages, connections and pivot nuts are secure and that wheel nuts are torqued correctly.  
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, switch off the cutterblade and powered sweep-  
er collector drives and ensure that the forward/reverse travel control pedal is in the neutral position.  
Watch out for traffic when crossing or near roadways.  
Use extreme caution when reversing.  
Switch off the cutterblade and powered sweeper collector brush drives before crossing surfaces other than grass.  
When using the garden tractor, never direct the discharge of material toward bystanders or allow anyone near the  
machine while in operation.

SAFETY PRECAUTIONS  
1.8  
OPERATION  
Continued.  
Never operate the garden tractor or powered sweeper collector with defective guards or shields or without  
safety protective devices in place and in good working order.  
Do not change governor settings to increase the speed of the engine. Operating an engine at excessive speed  
increases the hazard of injury.  
Before leaving the operator’s position:  
- Switch off the drive to the cutterblades and powered sweeper collector and lower the powered  
sweeper collector to the ground.  
- Engage the parking brake.  
- Stop the engine and remove the ignition key.  
Switch off the drive to the cutterblades and powered sweeper collector, stop the engine and disconnect the  
spark plug lead or remove the ignition key before:  
- Clearing blockages.  
- Checking, cleaning or working on the mower or powered sweeper collector.  
- Refuelling.  
- Removing the powered sweeper collector.  
- After striking a foreign object (inspect the mower for damage and make repairs before restart-  
ing the tractor).  
- If the machine starts to vibrate abnormally check immediately and call dealer if necessary.  
Reduce the throttle setting during engine run out.  
Do not use on a slope of more than 10 degrees.  
Ground conditions affect traction. Particular conditions may not permit safe operation on the slope  
limits stated.  
Remember there is no such thing as a" safe" slope. Travel on a grass slope requires particular care.  
To guard against overturning:  
- Exercise extreme care when changing direction on a slope.  
- Do not stop or start suddenly when going up or downhill.  
- Engage drive slowly, especially when travelling downhill.  
- Tractor speed should be kept low on slopes and during tight turns.  
- Stay alert for humps and hollows and other hidden hazards.  
- Keep away from sharp inclines and steep drops.  
- Never mow across the face of a slope.  
Never park on a slope.

SAFETY PRECAUTIONS  
1.9  
MAINTENANCE AND STORAGE  
Never store the tractor with petrol in the tank inside a building where fumes may reach an open flame or spark.  
When the tractor is to be parked, stored or left unattended turn the in-line fuel tap to the closed position,  
apply the parking brake and remove the ignition key.  
When the tractor is to be parked, stored or left unattended, raise the cutterdeck to the highest cut height and  
lower the powered sweeper collector to the ground.  
Check that all nuts, bolts and screws are tight to be sure the equipment is in safe working condition.  
Allow the engine to cool before storing in any enclosure.  
To reduce the risk of fire, keep the engine, silencer, fuel tank and battery compartment free of grass, leaves  
or excessive grease.  
Frequently check fuel lines and fittings for cracks or leaks and replace if necessary.  
Replace worn or damaged parts for safety.  
Ensure that all safety decals are properly secured and in good condition.  
If the fuel tank has to be drained, this should be done outdoors.  
Be careful during adjustment of the machine to prevent entrapment of the fingers between moving blades  
and fixed parts of the tractor.  
Never work on the tractor or sweeper collector while the engine is running.  
Health and Safety at Work Act:  
In accordance with section 6 of the Health and Safety at Work Act 1974, the garden tractor and powered  
sweeper collector have been designed and constructed so that, in so far as is reasonably practical, they will  
not endanger the safety and health of those working with them. This is, however, subject to the equipment  
being properly used and maintained according to the conditions stated in this manual and elsewhere, which  
have been found necessary as a result of the research and testing of Hayter Limited.

OPERATING THE TRACTOR  
1.19  
BEFORE STARTING THE ENGINE  
Check Oil Level: Note: The engine was filled with oil at the factory.  
Oil Type: SAE30 Engine oil, classified for service - SFminimum.  
Fuel Type: Always use clean, fresh unleaded petrol. Purchase fuel in quantities that can be used within 30  
days. Never mix oil with petrol. For added engine protection, Briggs and Stratton recommend the use of  
their fuel additive which is available from authorised Briggs and Stratton Service dealers.  
Check Fuel Level: Clean around the fuel filler cap before removing it. Do not overfill the tank. Allow  
6mm minimum of tank space for expansion.  
IMPORTANT: The fuel filler cap must be secured to prevent fuel leakage during operation.  
Check Tyres: Check the air pressure in the tyres. Incorrect pressure can cause the unit to ride badly and
