erator. 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. Reduced--kickback guide bars and low--kickback saw chains reduce the chance and magnitude of kickback and are recommended. 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 servic- ing 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.
