Safety Precautions
Training
READ THIS MANUAL BEFORE USING THE C34 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.
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 operating instructions to use the mower or its
attachments. Local regulations may restrict the age of the operator.
Be alert while people, especially children, or animals are nearby.
Bear in mind that the operator is responsible for accidents or hazards occurring to other people or
their property.
Do not attempt to ride on the mower or carry passengers.
All operators should seek and obtain professional and practical instruction. Such instruction should
emphasise:
-The need for care and concentration while working with the C34 mower.
-The need to slow down when making tight turning manoeuvres, particularly on slopes. Failure
to take adequate care can affect stability leading to loss of control of the mower.
-Control of a machine sliding on a slope will not be regained by the application of the brake. The
main reasons for loss of control on a slope are:
-Insufficient grip between roller and ground.
-Being driven too fast.
-Lack of awareness of ground conditions.

10
Preparation
While operating the equipment always wear substantial footwear and long trousers. Do not operate
the equipment when barefoot or wearing open sandals.
Ear protection should be worn when the engine is running.
Eye protection should be worn whilst mowing.
Thoroughly inspect the area that is to be cut and remove all objects which are likely to cause
damage to the machine.
Never operate the mower unless all belt and chain guards are correctly in place and securely
fastened.
Before use check the bottom blade and cylinder. Replace or sharpen if necessary
Petrol is highly flammable, therefore:
-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 fuel tank or add petrol while
the engine is running or while the engine is hot. Allow the engine to cool for at least two
minutes before refuelling. Be aware that the engine exhaust silencer will remain hot for some
time after the engine is switched off.
-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 spillage and avoid creating any source of ignition until the petrol
vapours have dissipated.
-Always use fresh fuel.
-Replace the fuel tank cap securely.

11
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 starting the engine, disengage drive to the cutting cylinder and the rear drive roller and
engage the parking brake.
Watch out for traffic when crossing or near roadways.
Always disengage drive to the cylinder before travelling over any surface other than grass.
When using the mower, never direct the discharged material towards bystanders or allow anyone
near the machine whilst it is in operation.
Never operate a mower with defective guards.
Do not attempt to increase the factory set maximum speed of the engine. Operating an engine at
excessive speed will lead to increased wear and tear and increases the risk of injury.
Before leaving the operator position:
-Disengage drive to the rollers.
-Disengage drive to the cylinder.
-Engage the parking brake.
-Switch the on/off switch on the handlebars to the OFF position.
Engage the parking brake, disengage drive to the cutting cylinder, switch off the engine and ensure
the cylinder is completely stationary:
-Before releasing blockages.
-Before checking, cleaning or working on the machine.
-After striking a foreign object inspect the mower for damage and rectify any problems before
continuing.
-Before refuelling.
-Before making cutter head adjustments.
If the machine starts to vibrate abnormally STOP immediately and check the machine over.
Never park the machine on a slope.
Reduce the throttle setting during run out
ALWAYS KEEP HANDS AND FEET WELL AWAY FROM A ROTATING CUTTING
CYLINDER.

12
Maintenance and storage
Always wear thick gloves when manually rotating a cutting cylinder.
Check that all nuts, bolts and screws are sufficiently tight so as to ensure that the equipment is in
safe working condition.
To reduce the risk of fire, keep the engine and exhaust area free of grass, leaves and other debris.
Wipe off excess grease.
Frequently check fuel lines and fittings for cracks or leaks and replace if necessary.
Replace worn or damaged parts.
Ensure that all safety decals are properly secured and in good condition.
Never work on the equipment while the engine is running.
Take care to prevent entrapment of the fingers between moving blades and fixed parts during
maintenance activities.
Allow the engine and exhaust to cool before storing in any enclosure.
If the fuel tank has to be drained this should be done outdoors.
Always chock the roller when the mower is being left in storage
Health and Safety at Work Act
In accordance with section 6 of the Health and Safety at Work Act 1974 the C34 has been designed and
constructed so that, in so far as is reasonably practical, it will not endanger the safety and health of those
working with it. 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 Turfmech Machinery Limited and Allett.
