RULES FOR SAFE OPERATION

1. Fatigue causes carelessness. Be more cautious before rest periods and before the end of your shift.

2. Personal protective clothing required by your safety organizations, government regulations, or your employer should be used; otherwise, sung fitting clothing, protective eyewear, safety footwear and hand, leg and hearing protection should be worn.

Note: Personal protective clothing

should meet the requirements of applicable Standards.

3. Before fueling, servicing or transporting your chain saw switch off the engine. To help prevent fire, restart your chain saw at least 3 m from the fueling area.

4. When using a chain saw a fire extinguisher should be available.

5. When felling, keep at least 2 tree lengths between yourself and your fellow workers.

6. Plan your work; assure yourself of an obstacle-free work area and, in the case of felling, of an escape path from the falling tree.

7. Follow instructions in your operator’s manual for starting the chain saw and control the chain saw with a firm grip on both handles when it is in operation. Keep handles dry, clean and free of oil. A chain saw should never be carried with the engine running.

8. When transporting your chain saw, use the appropriate transportation covers that should be available for the guide bar and saw chain.

9. Never operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. Never adjust the guide bar or saw chain when the engine operating.

10. Beware of carbon monoxide poisoning. Operate the chain saw in well-ventilated areas only.

11. Do not attempt a pruning or liming operation in a standing tree unless specifically trained to do so.

12. Guard against kickback. Kickback is the upward motion of the guide bar, which occurs when the saw chain, at the nose of the guide bar, contact an object. Kickback can lead to dangerous loss of the chain saw.

TO AVOID KICKBACK:

(a) Contact of the guide bar tip with any

object should be avoided.

(b) Tip contact may cause the guide bar

to move suddenly upward and backward which may cause serious injury.

operating the chain saw.

(d) Use a firm grip, thumbs and fingers

encircling the handles. (e) Don’t overreach. (f) Avoid cutting above shoulder height. (g) Follow the manufacture’s instructions

for sharpening and maintenance of

the saw chain.

13. When boring with the chain saw, the initial cut should be introduced with the lower part of the nose (tip) until the hole is sufficiently large so as to introduce the entire nose (tip) of the guide bar. This technique should reduce the danger of kickback.

14. A chain saw is intended for two-handed use. Serious injury to the operator, helpers and/or bystanders may result from one-handed operation.

CAUTION

A. Allow your chain saw to cool before

refueling, and do not smoke while refueling.

B. Do not allow other persons or animals

close to running chain saw or close to where a tree is being felled.

C. Use extreme caution when cutting small

size brush and saplings because slender material may catch the saw chain and be whipped toward you.

D. When cutting a limb that is under

tension is alert for spring-back.

OPERATOR SAFETY

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 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 and neck, feet and ankles and hands and wrists.

• Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks and also by not smoking.

• Limit the number of hours of operation. Try to fill each day with jobs where operating the chain saw, 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.

REPETITIVE STRESS INJURY

• It is believed that over-using the muscles and tendons of the finger, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain to the areas just mentioned. 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.

• Take periodic breaks to minimize repetition and rest your hands.

• Reduce the speed and force in which you do the repetitive movement.

• Do exercises to strengthen hand and arm muscles.

• See a doctor if you feel tingling, numbness or pain in your fingers, hands, wrists or arms. The sooner RSI/CTS is diagnosed, the more likely permanent nerve and muscle damage can be prevented.

EYE AND HEARING PROTECTION

• Wear eye protection goggles that meet ANSI Z 87.1 requirements. Goggles meeting the requirements have the mark “Z 87” stamped on them.

• Wear hearing protection. If this guideline is not followed, hearing loss can occur. ECHO recommends wearing hearing protection at all times.

WEAR PROPER CLOTHING

• Snug fitting durable clothing should be worn. Pants should have long legs, DO NOT WEAR SHORTS. Do not wear loose fitting clothing, scarves, neckties, jewelry or any item that may become tangled in surrounding growth or the chain saw itself.

• Wear shoes with non-skid soles. DO NOT wear open toed shoes or operate unit barefooted.

• Wear no-slip, heavy duty work gloves to improve your grip on the chain saw handles. The gloves also help reduce the transmission of machine vibration to your hands.

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.

AVOID HOT SURFACES

• During operation, the muffler or catalytic muffler and surrounding cover become hot.

• Never suspend the saw on a lanyard with the engine running.

• Always use the saw from the right-hand side of your body - NEVER from the left side.

• Always wear proper safety clothing to protect your lower body from sharp saw chain and hot muffler.

• Always keep exhaust area clear of flammable debris during transportation or when storing, otherwise serious property damage or personal injury may result.

CS-450P

SPARK ARRESTOR MUFFLER

• The spark arrestor muffler controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the muffler. Make sure the spark arrestor screen is in good repair and properly seated in the muffler.

• Certain internal combustion engines operated on forest, brush, and/or grass-covered areas in the states of Washington, Oregon, Idaho, California, Minnesota, New Jersey and Maine, are required to be equipped with a spark arrestor.

CORRECT USE OF CHAIN BRAKE

This requirement also applies to all U.S. Forest Service lands. In some of these areas, the spark arrestor system must be certified per USDA Forest Service Regulation SAE J335. Check with your local or state authorities for specific regulations in your area. Failure to follow these requirements is a violation of the law.

DANGER

Kickback safety precaution for chain saw users: Kickback may occur when the nose or tip of the guide bar touches an object or when the wood closes in and pinches the saw chain in the cut.

The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of operation. You should inquire through local government offices, your employer or your local dealer to ensure that your chain saw conforms to the required safety standard. ECHO chain brakes have been designed and tested to comply with international safety standards as follows.

Canada : CSA Standard Z 62.1,

Standard Z 62.3 CHAIN SAWS

USA : ANSI Standard B175.1 - 2000

Safety Requirement for chain saws

WARNING

CSA Z 62.1 stipulates that the brake shall stop the chain 0.12 seconds at an engine speed of 13500 r/min. It is the responsibility of the owner/operator to ensure that the brake is serviced, adjusted and tested strictly in accordance with the instructions as detailed herein in order to ensure that the brake performance is maintaind in compliance with the Standard CSA Z 62.1.
