S Low--Kickback Chain, designed with a contoured depth gauge and guard link which deflect kickback force and allow wood to gradually ride into the cutter. Low-- Kickback Chain has met kickback per- formance requirements when tested on a representative sample of chain saws be- low 3.8 cubic inch displacement specified in ANSI B175.1.

can be caused by allowing contact of the bar tip in the danger zone with any hard object. Kickback can also be caused by pinching the saw chain along the top of the guide bar. This action may push the guide bar rapidly back toward the operator. Either of these events may cause you to lose control of the saw which could result in serious injury or even death. DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Re- duced--kickback guide bars and low--kick- back saw chains reduce the chance and magnitude of kickback and are recom- mended. Your saw has a low kickback chain and bar as original equipment. Repairs on a chain brake should be made by an autho- rized servicing dealer. Take your unit to the place of purchase if purchased from a ser- vicing dealer, or to the nearest authorized master service dealer.

STip contact in some cases may cause a light- ning fast reverse REACTION, kicking guide bar up and back toward operator.

SPinching the saw chain along the top of the

guide bar may push the guide bar rapidly back toward the operator.

SEither of these reactions may cause you to lose control of the saw which could result in serious injury. Do not rely exclusively upon devices built into your saw.
