Under no circumstances may the machine be started without observing the safety instruc- tions. Should the user fail to comply with these, Husqvarna Construction Products Sweden AB or its representatives are free from all liability both directly and indirectly. Read through these operating instructions and make sure that you understand the contents before starting to use the machine. Should you, after reading these safety in- structions, still feel uncertain about the safety risks involved you must not use the machine, please contact your dealer for more informa- tion.

Please read the operator’s manual carefully.

Only qualified staff should be allowed to operate machinery.

Never use a machine that is faulty. Carry out the checks, maintenance and service instructions de- scribed in this manual. All repairs not covered in this manual must be performed by a repairer nominated by either the manufacturer or distributor.

Always wear personal safety equipment such as sturdy non-slip boots, ear protection, dust mask and approved eye protection.

The machine should not be used in areas where potential for fire or explosions exist.

Machinery should only be started when grinding heads are resting on the ground unless carrying out a testing procedure as outlined in this manual.

The machine should not be started without the rubber dust skirt attached. It is essential a good seal between machine and floor be established for safety, especially when operating in dry grinding applications.

When changing the grinding discs ensure power supply to the unit is OFF by engaging the Emergen- cy Stop button and the power-plug disconnected.

The machine should not be lifted by handles, mo- tor, chassis or other parts. Transportation of the machine is best done on a pallet / skid to which the machine must be firmly secured.

Extreme caution must be used when moving machinery by hand on an inclined plane. Even the slightest slope can cause forces/momentum making the machinery impossible to brake manually.

Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co- ordination.

Never use a machine that has been modified in any way from its original specification.

Be on your guard for electrical shocks. Avoid having body contact with lightning-conductors/metal in the ground.

Never drag the machine by means of the cord and never pull out the plug by pulling the cord. Keep all cords and extension cords away from water, oil and sharp edges.

Make sure the cord is not pinched in doors, fences or the like.

Check that the cord and extension cord are intact and in good condition. Never use the machine if the cord is damaged, hand it in to an authorized service workshop for repair.

Do not use a rolled up extension cord

The machine should be connected to an earthed outlet socket.

Check that the mains voltage corresponds with that stated on the rating plate on the machine.

Ensure the cord is behind you when you start to use the machine so that the cord will not be damaged.

At no time should lifting of machinery be attempted without mechanical means such as a hoist or fork lift.

WARNING!

Overexposure to vibration can lead to circula- tory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overex- posure to vibration. These symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally ap- pear in the fingers, hands or wrists.
