SAFETY

Rules For Safe Operation

Kickback Safety Precautions 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 a nd pinches t he saw chain in the cut.

Tip contact in some cases may cause a lightning fast reverse REACTION, Kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards th e op e rator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury.

The tip guard device is not installed on the guide bar when you purchase your chain saw. The tip guard can be used in a majority of cutting operations, and is especially recommended for beginners, homeowners, or chain saw novices. Most cutting operations can be accomplished with the tip guard in place.

Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, y ou should take several steps to keep your cutting jobs free from accident or injury.

SAFETY CS-310

Kickback Danger Zone

Linear kickback

Kickback

Pinch

Locked

1. With a basic understanding of

kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

2. Keep a good firm grip on the saw

with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. A firm grip will help you reduce kickback and maintain control of the saw. Don’t let go.

3. Make sure that the area in which

you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, or any other obstruction which could be hit while you are operating the saw.

4. Cut at high engine speeds.

5. Do not overreach or cut above

shoulder height.

6. Follow manufacturer’s sharpening and maintenance instructions for the

saw chain.

7. Only use replacement bars and chains specified by the manufacturer or

the equivalent.

Correct Use Of Chain Brake

Chain Brake Operation

• Set the lever in the unlocked

position before starting to cut.

• If the brake is tripped by kickback

reaction, the chain will stop immediately. Release the throttle to avoid possible damage to the engine or clutch.

• Do not attempt to operate the engine with the brake locked.

6 X7503275300

CS-310 SAFETY

Unlocked

Testing The Brake

• Start the engine on a solid level surface and run at a fast idle until warm.

• Hold the saw firmly by the handles and accelerate the engine to a fast idle.

• Slowly operate the chain brake lever while holding the saw firmly on the ground. When the brake lever trips, the chain should stop. Immediately release the throttle trigger.

Do not allow the saw to tip forward in order to avoid damage to the chain.

If the chain does not stop immediately, return the saw to your authorized dealer for repair.

Note:

• For practice, while cutting a small tree, push the lever f orward to lock the brake.

• Confirm that the brake works properly before each use.

• If the chain brake is clogged with wood chips, function of the brake may deteriorate. Always keep the de vice clean.

• Do not increase engine RPM's while the chain brake is locked.

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.

Chain brakes have been designed and tested to comply with international safety standards as follows.

USA: ANSI Standard B175.1 Safety Requirement for chain saws

X7503275300 7

SAFETY CS-310

35 cm

(14 in.)

ANSI Standard B175.1 stipulates that the brake shall stop the chain 0.12 seconds at an engine speed of 13,500 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 here in order to ensure that the brake performance is maintained in compliance with the Standard B175.1.

Automatic Chain Brake

Kickback produced from the tip of the guide bar will trip the automatic chain brake. To make sure that the automatic chain brake operates properly, follow these steps:

1. Stop the engine.

2. Hold the saw with the guide bar approximately 35 cm (14 in.) above a wooden surface. Right hand should hold the rear handle, and left hand should hold the front handle.

3. Release the front handle and drop the end of the guide bar against the wooden surface.

4. The impact should lock the chain brake.

When checking the operation of the automatic chain brake, use a sof t surface substance like wood to absorb the imp act so the chain is not damaged.

Other Safety Precautions

1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for twohanded use.

2. Do not operate a chain saw when you are fatigued.

8 X7503275300

CS-310 SAFETY

3. Use safety footwear, snug-fitting clothing and protective gloves. Wear eye, hearing, and head protection devices.

4. Use caution when handling fuel. Move the chain saw at least 3 m (10 feet) from the fueling point before starting the engine.

5. Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.

6. Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.

7. Keep all parts of your body away from the saw chain when the engine is running.

8. Before you start the engine, make sure that the saw chain is not contacting anything.

9. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the muffler away from your body.

10. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

11. Shut off the engine before setting the chain saw down.

12. Use extreme caution when cutting small size bru s h and saplings because slender material may catch the saw chain and be whipped toward you or pu l l you off balance.

13. When cutting a limb that is under tension, be alert for spring-back so that you will not be struck when the tension in the wood fibers is released.

14. Keep the handles dry, clean, and free of oil or fuel mixture.

15. Operate the chain saw only in well ventilated areas.

16. Do not operate a chain saw in a tree unless you have been specifically trained to do so.

17. All chain saw service, other than items listed in the Instruction manual maintenance instructions, should be performed by competent service personnel. (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and could subsequently cause the flywheel to burst.)

18. When transporting your chain saw, use the appropriate guide bar scabbard.

19. A spark arrestor muffler approv ed to SAE Standard J335 is standard on this chain saw to reduce the possibility of forest fires. Do not operate the chain saw with a loose or defective muffler. Do not remove the spark arrestor screen.

Extended Operation / Extreme Conditions

Prolonged exposure to cold and/or vibration may result in injury. Read and follow all safety and operation instructions to minimize risk of injury. Failure to follow instructions may result in painful wrist/hand/arm injuries.

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 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.

X7503275300 13

SAFETY CS-310

Repetitive Stress Injuries (RSI)

It is believed that overusin g 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). 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 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. The sooner RSI/CTS is diagnosed, the more likely permanent nerve and muscle damage can be prevented.

All over head electrical conductors and communications wires can have electricity flow with high voltages. This unit is not insulated against electrical current. Never touch wires directly or indirectly, otherwise serious injury or death may result.

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