SAFETY INSTRUCTIONS

Never mow while barefoot or wearing open sandals or thongs. Wear long trousers and heavy shoes.

Know your controls. Read the owner’s manual carefully. Learn how to stop the engine quickly in any emergency.

Make sure the lawn is clear of sticks, stones, bones, wire and debris. They could be thrown by the blades.

Stop the engine and disconnect the spark plug wire before clearing blockages, checking or working on the mower.

Before using, always inspect to see that blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

DAMAGED BLADES AND WORN BOLTS ARE MAJOR HAZARDS.

Check all nuts, bolts and screws often; always be sure the mower is in a safe operating condition. Use only replacement parts made and guaranteed by the original manufacturer of your mower.

Refuel outdoors only. Do not smoke while fuelling engine. Add fuel before starting the engine. Never remove the cap of the fuel tank or add petrol while the engine is running or the engine is hot. If petrol is spilled, do not attempt to start the engine but move machine away from the area of the spill and avoid creating any source of igniton until petrol vapours have dissipated.

Do not mow whilst people, especially children or pets are in the mowing area.

Replace worn or faulty silencers.

Mow only in good daylight.

Never use the mower unless the grass catcher or guards (rear flap) provided by the manufacturer are in position.

Start the engine carefully with feet well away from the blades.

Do not operate engine in a confined space where exhaust fumes (carbon monoxide) can collect.

Stop the engine whenever you leave the mower, even for a moment.

Do not allow children or people unfamiliar with these instructions to use the mower.

Store the mower in a well-ventilatedroom away from naked flames such as may be found in hot water heaters.

Do not over-speedthe engine or alter governor settings. Excessive speed is dangerous and shortens mower life.

It is advisable to wear suitable eye protection when operating a mower.

Turn the fuel off at the conclusion of mowing and reduce the throttle setting during engine run-out.

Store fuel in a cool place in a container specifically designed for the purpose. In general, plastic containers are unsuitable.

Stop the engine, disconnect the spark plug wire and inspect the mower if :

a)the mower begins to vibrate abnormally; or

b)after striking a foreign object.

Never cut grass while walking backwards.

Stop the engine before pushing mower across gravel drives, walks or roads.

Walk, never run.

Mow across the face of slopes, never up and down. Exercise extreme caution when changing direction on slopes. Do not mow excessively steep slopes.

Never pick up or carry a mower when it is operating.
