SAFETY

- Always use fresh fuel. Stale fuel can block the carburettor and cause
leakage.

- Replace fuel tank and oil tank caps securely.

A damaged cutter device or impeller or both must be replaced. Before
use, always visually inspect the cutting mechanism to ensure that it is
in good condition. Do not operate the machine with an out of balance
cutting device or impeller.

- Check all nuts and bolts and tighten when necessary.

Do not operate the engine in a confined space where exhaust fumes
(carbon monoxide) can collect. Refuel outdoors only and do not smoke
while refuelling.

Always pull the starter cord slowly until resistance is felt. Then pull
the cord rapidly to avoid kickback and prevent hand or arm injury.

Operate only in daylight or good artificial light.

Avoid using the machine on wet grass, where feasible.

Always be sure of your footing on slopes.

Walk, never run.

Operate across the face of slopes, never up and down.

Exercise extreme caution when changing direction on slopes.

Do not use on excessively steep slopes.

Use extreme caution when pulling the machine towards you.

Stop the engine before moving the machine across areas other than
grass.

Do not change the engine governor settings or overspeed the engine.

Start the engine carefully, with feet well away from the cutting device.
