►The operator or user is responsible for accidents or hazards occurring to other people or their property.

►Do not operate the machine when barefoot or wearing open sandals, always wear substantial footwear and long trousers.

►Thoroughly inspect the area where the machine is to be used and remove all stones, sticks, wires, bones and other foreign objects.

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

►Mow only in daylight or in good artificial light.

►Avoid mowing in bad weather conditions especially when there is a risk of lightning.

Do not mow on excessively steep slopes.

Always be sure of your footing on slopes or wet grass.

Mow across the face of slopes – never up and down.

Exercise extreme caution when changing direction on slopes.

►Use extreme caution when stepping back or pulling the machine towards you.

►Never mow by pulling the mower towards you.

►Stop the blades if the machine has to be tilted for transportation when crossing surfaces other than grass and when transporting the machine to and from the area to be mowed.

►Do not tilt the machine when starting or switching on the motor, except if the machine has to be tilted for starting in long grass. In this case, do not tilt it more than absolutely necessary and tilt only the part which is away from the operator. Always ensure that both hands are in the operating position before returning the machine to the ground.

►Do not put hands or feet near or under rotating parts.

►Always stand clear of the discharge zone when operating the machine.

►Keep supply cables and extension cables away from the blade. The blade can cause damage to the cables and lead to contact with live parts. Beware electric shock hazard.

► Do not modify this product. Unauthorized modifications may impair the safety of your product and may result in increased noise and vibration.

►Regularly inspect the supply cable and any extension cables. Do not connect damaged cables to the supply or touch a damaged cable before it is disconnected from the supply. A damaged cable can lead to contact with live parts. Beware electric shock hazard.
