Proper clothing and safety gear must be worn when operating the unit.

Eye Protection:

Eye protection that meets ANSI Z87.1 or CE requirements must be worn whenever you operate the unit.

For additional safety, a full-face shield may be worn over safety glasses or goggles to provide protection from sharp branches or flying debris.

Hand Protection:

Wear sturdy, no-slip, rubber work gloves to improve your grip on the handles. Gloves also provide protection against cuts and scratches, cold environments, and reduce the transmission of machine vibration to your hands.

Hearing/Ear Protection:

It is recommended to wear personal protection whenever the unit is used.

Breathing Protection:

Operators who are sensitive to dust or other common airborne allergens may need to wear a dust mask to prevent inhaling these materials while operating the unit.

Proper Clothing:

Wear snug-fitting, durable clothing:

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

DO NOT WEAR SHORTS.

DO NOT WEAR TIES, SCARVES, JEWELRY, or clothing with loose or hanging items that could become entangled in moving parts or surrounding growth.

Keep clothing buttoned or zipped, and keep shirt tails tucked in.

Wear sturdy work shoes with nonskid rubber soles:

DO NOT WEAR OPEN TOED SHOES.

DO NOT OPERATE UNIT BAREFOOTED.

Keep long hair away from engine and air intake. Retain hair with a cap or net.

Prolonged exposure to cold and/or vibration may result in injury. 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. The following precautions are strongly recommended:

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 unit 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.

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.

Take periodic breaks to minimize repetition and rest your hands.

Reduce the speed and force with which you do the repetitive movement.

Do exercises 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 fingers, hands, wrists, or arms.

Before using the SHINDAIWA M262, perform the following checks:

Check the unit for loose/missing nuts, bolts, and screws. Tighten and/or replace as needed.

Inspect guards and shields for damage and to ensure that they are securely in place. Replace if damaged or missing.

Check that the attachment is firmly attached and in safe operating condition.

Check that the handle and harness (if included) are adjusted for safe, comfortable operation. See the Assembly Section for proper adjustment.

Periodically check the fuel system (fuel lines, vent, grommet, fuel tank, and fuel cap) for leaks, especially if the unit is dropped. If damage or leaks are found, do not use the unit. Have it repaired by an authorized servicing dealer before using.
