KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS

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 toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively on the safety devices built into your saw. As a chain saw user you should take several steps to keep cutting jobs free from accident or injury

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 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 chainsaw handles. A firm grip will help you reduce kickback and maintain control of the saw.
3. Make certain 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 speed.
5. Do not overreach or cut above shoulder height.
6. Follow manufactures sharpening and maintenance instructions for saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.

MAINTENANCE

• In order to maintain your product in proper working order, perform the maintenance and checking operations described in the manual at regular intervals.

This product has accordingly been designed with a ventilation hatch the back of the air cleaner cover to allow warm air to be supplied to the engine and to thereby prevent icing from occurring. Under normal oircumstances the product should be used in normal operating mode, i.e., in the mode to which it is set at the time of shipment However when the possibility exists that icing may occur, the unit should be set to operate in anti-freeze mode before use. (F15)
HOW TO SWITCH BETWEEN OPERATING MODES (F15)

1. Flip the engine switch to turn off the engine.
2. Remove the air cleaner cover from the cylinder cover.
3. Loosen a screw and remove the screen on the back of the air cleaner cover.

   • (1) Air cleaner cover
   • (2) Anti-icing plate
   • (3) Screw
   • (4) Normal operating mode
   • (5) Anti-freeze mode
   • (6) Screen

WARNING: Continuing to use the product in anti-freeze mode even when temperatures have risen and returned to normal may result in the engine failing to start properly or in the engine failing to operate at its normal speed, and for this reason you should always be sure to return the unit to normal operating mode if there is no danger of icing occurring. When using the saw with the anti-freeze mode, frequently check the screen and keep it clean of saw dust.
CHAIN BRAKE
This machine is equipped with an automatic brake to stop saw chain rotation upon the occurrence of kickback while in saw cutting operation. The brake is automatically operated by inertial force which acts on the weight fitted inside the front guard. This brake can also be operated manually with the front guard turned down to the guide bar. (F16)
To release the brake, pull up the front guard toward the front handle till a” click” sound is heard.
[Caution] Be sure to confirm brake operation during the daily inspection
How to confirm

1. (1) Turn off the engine.
