• Wear proper clothing to protect legs and other exposed parts of your body.
• Wear non-skid sole shoes. Do not wear open-toed shoes or operate unit while bare footed.
• Wear eye and hearing protection devices (?).
• Use caution when handling fuel. Put the caps back tightly on both the fuel can and the engine drill fuel tank. Move at least 3 meters (m) from the re-fuelling point and be sure there is no leakage of fuel from the fuel tank cap or the fuel system before starting the engine.
• Operate this petrol-powered engine equipment in a well-ventilated area only.
• Start the unit on the ground with the throttle set at idle. Do not start if the drills are obstructed by the ground or any other object.
• Never allow children to use the machine.
• Do not allow anyone to hold the material you are drilling.
• Keep a firm grip on the engine drill with both hands, one hand on the front handle, the other hand on the rear handle.

❗ WARNING

ALWAYS STOP THE ENGINE WHEN A DRILL JAM OCCURS. DO NOT ATTEMPT TO REMOVE AN OBJECT CAUSING A DRILL JAM IF THE ENGINE IS RUNNING. PHYSICAL INJURY CAN OCCUR IF A DRILL JAM IS REMOVED AND THE DRILLS START MOVING.

• Do all drilling at full throttle speed. Drilling at less than full speed can damage the clutch by allowing it to slip.

❗ WARNING

USE A FIRM GRIP WITH THUMBS AND FINGERS ENCIRCLING THE HANDLES. A FIRM GRIP WILL HELP YOU KEEP CONTROL OF THE ENGINE DRILL. NEVER OPERATE THE ENGINE DRILL WITH ONLY ONE HAND OR BODILY INJURY CAN OCCUR.

• Always carry the engine drill with the engine stopped and the HOT muffler away from your body.

Protective Equipment

• Always wear eye protection goggles that meet the national standards.
• Wear hearing protection (?). ECHO recommends that hearing protection be worn at all times.
• 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.
• While operating the machine, always be sure of a secure position.
• Wear non-slip, heavy-duty work gloves (?) to improve your grip on the engine drill handles. The gloves also help reduce the transmission of machine vibrations to your hands.

Protecting Others

Spectators, children, fellow workers, and animals must be warned to come no nearer than 5 meters (m) while the engine drill is in use. People working in the area near you should wear the same protective equipment as the operator.

Physical Condition and Repetitive Stress Injuries

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. ? (Illustration of a bottle and crossed-out glass)

Repetitive Stress Injuries (RSI)

It is believed that over-using the muscles and tendons of the fingers, hands, arms, and shoulders may cause soreness, swelling, numbness, weakness, and extreme pain in those areas. Certain repetitive hand activities may put you at a high risk for developing a Repetitive Stress Injury (RSI).

To reduce the risk of RSI/CTS, do the following:

• Avoid using your wrist in a bent, extended, or twisted position. Instead, try to maintain a straight wrist position. Also, when grasping, use your whole hand, not just the thumb and index finger. Diagram showing correct and incorrect wrist/hand posture.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive movement.
• Do exercise to strengthen the hand and arm muscles.
• See a doctor if you feel tingling, numbness, or pain in the fingers, hands, wrists, or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve and muscle damage can be prevented.

❗ WARNING

IF INTENDED USE INVOLVES PROLONGED PERIODS OF OPERATION, THIS MAY CAUSE CIRCULATORY PROBLEMS IN THE USER'S HANDS DUE TO VIBRATION.

Precaution Against Vibration and Cold:

It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of certain individuals, may be brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sensations followed by loss of color and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.

• KEEP YOUR BODY WARM, ESPECIALLY THE HEAD, NECK, FEET, ANKLES, HANDS, AND WRISTS.
• MAINTAIN GOOD BLOOD CIRCULATION BY PERFORMING VIGOROUS ARM EXERCISES DURING FREQUENT WORK BREAKS AND ALSO BY NOT SMOKING.
• LIMIT THE HOURS OF OPERATION. TRY TO FILL EACH DAY WITH JOBS WHERE OPERATING THE ENGINE DRILL OR OTHER HAND-HELD POWER EQUIPMENT IS NOT REQUIRED.
• IF YOU EXPERIENCE DISCOMFORT, REDNESS, AND SWELLING OF THE FINGERS FOLLOWED BY WHITENING AND LOSS OF FEELING, CONSULT YOUR PHYSICIAN BEFORE FURTHER EXPOSING YOURSELF TO COLD AND VIBRATION. Diagrams showing protective gear, thermometer, and a person consulting a doctor about numb fingers.
