your left arm straight with the elbow locked.

KICKBACK SAFETY FEATURES

WARNING: The following features are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this danger. As a chain saw user, do not rely only on safety de- vices. You must follow all safety precau- tions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury.

SReduced--Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. A Reduced--Kickback Guide Bar has been demonstrated to significantly re- duce the number and seriousness of kick- backs.

SFront Hand Guard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handlebar.

SPosition of front and rear handlebars, de- signed with distance between handles and “in-line” with each other. The spread and “in-line” position of the hands provided by this design work together to give balance and resistance in controlling the pivot of the saw back toward the operator if kick- back occurs.

WARNING: DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROP- ERLY AND CAREFULLY TO AVOID KICK- BACK. Reduced--kickback guide bars and low--kickback 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 authorized servicing dealer. Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest authorized master service dealer.

STip contact in some cases may cause a light- ning fast reverse REACTION, kicking the

guide bar up and back toward the 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 the safety devices built into your saw.

CHAIN BRAKE

SChain Brake, designed to stop the chain in the event of kickback.

WARNING: Your chain saw is equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.

DO NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK.

Bringing together a blend of innovative technologies and user-friendly features, these models have been designed to ensure that tasks such as tree pruning, firewood cutting, and light felling can be conducted efficiently and safely.

This feature not only extends the life of the chainsaw but also enhances cutting efficiency. Additionally, the chain tensioning system is designed for easy adjustments, providing users with the ability to maintain the proper tension with minimal effort.

Safety is also a key consideration in the design of the Husqvarna 137 and 142. These models feature a chain brake that effectively stops the chain's movement in the event of kickback, protecting the operator from potential injury. Furthermore, the anti-vibration technology integrated into the handles helps to reduce vibrations felt by the user, contributing to a more comfortable and safer operating experience.

The ergonomic design is complemented by an intuitive layout, with controls that are easy to access and operate. The combination of performance, safety features, and user-centric design makes the Husqvarna 137 and 142 excellent choices for anyone needing a dependable chainsaw for various tasks.
