personal condItIon and safety equIpment

WARNING

Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions are not followed. Proper clothing and safety gear must be worn when operating unit.

ENGLISH

Physical Condition

Your judgment and physical dexterity may not be good:

• if you are tired or sick,

• if you are taking medication,

• if you have taken alcohol or drugs. Operate unit only if you are physically and mentally well.

Eye Protection

Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.

Hand Protection

Wear no-slip, heavy-duty work gloves to improve your grip on the handle. Gloves also reduce the transmission of machine vibration to your hands.

Hearing Protection

Shindaiwa recommends wearing hearing protection whenever unit is used.

Proper Clothing

Wear snug tting, durable clothing;

• Pants should have long legs, shirts with long sleeves.

• DO NOT WEAR SHORTS,

• DO NOT WEAR TIES, SCARFS, JEWELRY. Wear protective hair covering to contain long hair.

Wear sturdy work shoes with nonskid soles;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

Hot Humid Weather

Heavy protective clothing can increase operator fatigue which may lead to heat stroke. Schedule heavy work for early morning or late afternoon hours when temperatures are cooler.

Extended Operation/Extreme Conditions

It is believed that a condition called Raynaud’s Phenomenon, which affects the ngers of certain individuals, may be

brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sensa-

tions, followed by loss of color and numbness in the ngers. 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 ll each day with jobs where operating the unit or other hand-held power equipment is not required.

• If you experience discomfort, redness, and swelling of the ngers followed by whitening and loss of feeling, consult your physician before further exposing yourself to cold and vibration.

Repetitive Stress Injuries

It is believed that overusing the muscles and tendons of the ngers, 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). An extreme RSI condition is Carpal Tunnel Syndrome (CTS), which could occur when your wrist swells and squeezes a vital nerve that runs through the area. Some believe that prolonged exposure to vibration may contribute to CTS. CTS can cause severe pain for months or even years. 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 nger.

• 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.

• Immediately stop using all power equipment and consult a doctor if

you feel tingling, numbness, or pain in the ngers, hands, wrists, or

arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve and muscle damage can be prevented.

DANGER

Do not operate this product indoors or in inadequately ventilated areas. Engine exhaust contains poisonous emissions and can cause serious injury or death.

ENGLISH

Level 2.

Tools required: 3 mm Hex wrench, 25 or 50 mm (1 or 2 in.) clean-

ing brush

Parts required: None if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder n area. This ow of air carries combustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes in the crankcase are blocked, preventing cooling air from

reaching the cylinder.

• Dust and grass build up on the outside of the cylinder. This build up

insulates the engine and prevents the heat from leaving.

Removal of crankcase cooling passage blockages or cleaning of cooling

ns is considered “Normal Maintenance.” Any failure attributed to lack

of maintenance is not warranted.

Remove spark plug lead and spark plug.

Remove (4) starter cover hex socket bolts and starter.
