INPORTANT SAFETY INSTRUCTIONS

USA013-1

WARNING:

WHEN USING A CORDLESS CHAIN SAW, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND INJURY TO PERSONS, INCLUDING THE FOLLOWING:

READ ALL INSTRUCTIONS

1. Keep Work Area Clean

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

2. Consider Work Area Environment

Use extreme caution when cutting small size brush and saplings because the slender material may catch the saw chain and be whipped toward you or pull you off balance. Do not operate a chain saw in a tree unless specifically trained to do so. 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. Do not expose chain saw to rain. Do not use chain saw in damp or wet locations. Do not use chain saw in presence of flammable liquids or gases.

3. Guard Against Electric Shock Prevent body contact with grounded surfaces. For example: metal pipes, wire fences.

4. Keep Children Away Do not let visitors contact chain saw. All visitors should be kept away from work area.

5. Store Idle Chain Saw When not in use, chain saws should be stored in a dry, and high or locked-up place - out of the reach of children. When storing saw, use a scabbard or carrying case.

6. Do not Force Chain Saw It will do the job better and safer at the rate for which it was intended.

7. Use Right Tool Cut wood only. Do not use chain saw for purpose not intended - for example - Do not use chain saw for cutting plastic, masonry non-wood building materials.

8. Dress properly Do not wear loose clothing or jewelry. They can get caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair.

9. Use Safety Glasses Also use safety footwear; snug fitting clothing; protective gloves; and head protection.

10. Carrying Saw Carry the chain saw with the saw stopped, finger off the switch, the guide bar and saw chain to the rear.

11. Maintain Chain Saw With Care Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Keep handles dry, clean, and free from oil and grease.

12. Disconnect Chain Saw Disconnect battery cartridge from chain saw when not in use, before servicing, and when changing accessories and attachments, such as saw chain and guard.

13. Stay Alert Watch what you are doing. Use common sense. Do not operate chain saw when you are tired. Keep all parts of the body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.

14. Check Damaged Parts Before further use of the chain saw, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this instruction manual. Have defective switches replaced by authorized service center. Do not use chain saw if switch does not turn it on and off. Do not 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 trigger is released.

15. Guard Against Kickback WARNING: 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. 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 the operator. Either of these reactions may cause you to lose control of the saw which could result in serious injury to user. The following precautions should be followed to minimize kickback.

(1) Grip Saw Firmly. Hold the chain saw firmly

with both hands when the motor is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.

(2) Do not over reach. (3) Keep proper footing and balance at all times. (4) Do not let the nose of the guide bar contact

a log, branch, ground, or other obstruction.

(5) Do not cut above shoulder height. (6) Use devices such as special guide bars that

reduce the risks associated with kickback.

(7) Only use replacement bars and chains spec-

ified by the manufacturer.

16. Replacement Parts when servicing use only identical replacement parts.

17. Before marking a felling cut, remove dirt, stones, loose bark, nails, staples and wire from the tree.

18. Secure the log so that it will not roll or move suddenly during operation.

19. AVOID UNINTENTIONAL STARTING. Do not carry the tool with finger on switch. Be sure switch is in OFF position before inserting battery cartridge.

20. Attention! Do not expose this tool to rain.

21. The chain saw must not be left outdoors during rain and it must not be used when wet.

22. Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
