PROTECTIVE EQUIPMENT

WARNING PRECAUTION AGAINST VIBRATION AND COLD

• Always wear protection goggles that meet the national standards.

• Wear hearing protection. If you use the unit for less than two hours per day, we recommend that hearing protection be worn at all times.

IT IS BELIEVED THAT A CONDITION CALLED RAYNAUD’S PHENOMENON WHICH AFFECTS THE FINGERS OF CERTAIN INDIVIDUALS IS BROUGHT ABOUT BY EXPOSURE TO COLD AND VIBRATION. ACCORDINGLY, YOUR ECHO TRIMMER HAS SHOCK MOUNT AND RUBBERED GRIP. DESIGNED TO REDUCE THE INTENSITY OF VIBRATION TRANSMITTED THROUGH THE HANDLES. EXPOSURE TO COLD AND VIBRATION MAY CAUSE TINGLING AND BURNING, FOLLOWED

BY LOSS OF COLOUR AND NUMBNESS IN A PERSON’S FINGERS. WE STRONGLY RECOMMEND YOU TAKE THE FOLLOWING PRECAUTIONS BECAUSE THE MINIMUM EXPOSURE WHICH MIGHT TRIGGER THE AILMENT IS UNKNOWN.

• Dress properly! Do not wear loose clothing or jewellery, they can be caught in moving parts. Use of sturdy gloves, non-skid footwear, and safety glasses is recommended.

• KEEP YOUR BODY WARM - ESPECIALLY HEAD, NECK, FEET AND ANKLES, AND HANDS AND WRISTS.

• While operating the machine be always sure of a secure position.

• MAINTAIN GOOD BLOOD CIRCULATION BY PERFORMING VIGOROUS ARM EXERCISES DURING FREQUENT WORK BREAKS, AND ALSO BY NOT SMOKING.

• Wear non-slip, heavy-duty work gloves to improve your grip on the trimmer handles. The gloves also help reduce the transmission of machine vibrations to your hands.

• LIMIT THE NUMBER OF HOURS OF OPERATION. TRY TO FILL A PART OF EACH WORK DAY WITH JOBS WHERE OPERATING THE TRIMMER OR OTHER HAND-HELD POWER TOOLS IS NOT REQUIRED.

PROTECTING OTHERS Spectators, children, fellow workers and animals must be warned to come no nearer than 10 m while the trimmer is in use.

People working in the area near you should wear the same protective equipment as the operator.

• IF YOU EXPERIENCE DISCOMFORT, REDNESS AND SWELLING OF THE FINGERS, FOLLOWED WHITENING AND LOSS OF FEELING, CONSULT YOUR PHYSICIAN BEFORE EXPOSING YOURSELF FURTHER TO COLD AND VIBRATION.

Always be aware of your surroundings and stay alert for possible hazards that you may not hear due to the noise of the machine.

PHYSICAL CONDITION Your judgement and dexterity may be impaired if you are ill or have taken alcohol or other substances known to affect the way you would normally function.

Painful or numb fingers?

See your doctor

OPERATING TECHNIQUES • Before trimming, check the area and remove all obstacles and objects that could be thrown.

• Do not force the blades and only move as quickly as the blades will allow.

• Stop the engine and disconnect from ignition cable before: - cleaning or when clearing a blockage; checking, maintenance or working on the machine.

• Handle fuel with care; it is highly flammable. Never add fuel to a machine with a running or hot engine.

• Do not attempt to repair the machine unless you are qualified to do so.

• Do not operate the machine with a damaged or excessively worn cutting device.

• Always ensure all handles and guards are fitted when using the machine. Never attempt to use an incomplete machine or one fitted with an unauthorized modification.

• Plan to trim regularly to make it easier to keep neat edges and to avoid having to make more than one pass.

• When transporting or storing the machine always fit the blade cover.

• When starting to trim, run the engine at full throttle.

• To reduce fire hazard keep engine and silencer free of debris, leaves or excessive grease.
