SRoll the log over and finish with a second overcut.

SGive special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log.

BUCKING USING A LOG OR SUP- PORT STAND

SRemember your first cut is always on the

pressure side of the log.

S Your first cut should extend 1/3 of the diameter of the log.

SFinish with your second cut.

LIMBING AND PRUNING

WARNING: Be alert for and guard against kickback. Do not allow the moving chain to contact any other branched or objects at the nose of the guide bar when limbing or pruning. Allowing such contact can result in serious injury.

WARNING: Never climb into a tree to limb or prune. Do not stand on ladders, plat- forms, a log, or in any position which can cause you to lose your balance or control of the saw.

IMPORTANT POINTS

S Watch out for springpoles. Use extreme caution when cutting small size limbs. Slen- der material may catch the saw chain and be whipped toward you or pull you off balance.

S Be alert for springback. Watch out for branches that are bent or under pressure. Avoid being struck by the branch or the saw when the tension in the wood fibers is released.

SKeep a clear work area. Frequently clear branches out of the way to avoid tripping over them.

LIMBING

SAlways limb a tree after it is cut down. Only

then can limbing be done safely and prop- erly.

S Leave the larger limbs underneath the felled tree to support the tree as you work.

SStart at base of the felled tree and work to-

ward the top, cutting branches and limbs. Remove small limbs with one cut.

SKeep the tree between you and the chain

as much as possible.

SRemove larger, supporting branches with

the cutting techniques described in BUCK-

ING WITHOUT A SUPPORT.

S Always use an overcut to cut small and freely hanging limbs. Undercutting could cause limbs to fall and pinch saw.

PRUNING

WARNING: Limit pruning to limbs shoulder height or below. Do not cut if branches are higher than your shoulder. Get a professional to do the job.

SMake your fist cut 1/3 of the way through the bottom of the limb.

SNext make a 2nd cut all the way through the limb. Then cut a third overcut leaving a 1 to 2 inch collar from the trunk of the tree.

CS 2137 specifications

The Jonsered CS 2137 is a high-performance chainsaw designed for both professional and avid hobbyist use. Known for its exceptional power-to-weight ratio, the CS 2137 provides users with an efficient and reliable tool for various cutting tasks, from tree felling to firewood preparation.

One of the main features of the Jonsered CS 2137 is its powerful 37cc two-stroke engine. This engine delivers robust performance while maintaining a lightweight profile, making it easy for users to maneuver the saw during extended use. The design of the engine promotes fuel efficiency, allowing users to work longer without frequent refueling. Additionally, the engine is equipped with advanced starter technology, ensuring easy starts even in cold conditions.

The CS 2137 is built with a 14 to 18-inch bar length, offering versatility for different cutting applications. This allows users to switch between various tasks, whether it’s trimming branches or cutting down smaller trees. The bar and chain design ensures smooth and efficient cutting, enhancing overall productivity.

A significant aspect of the Jonsered CS 2137 is its anti-vibration system. This feature minimizes user fatigue during extended use, allowing for greater comfort and enhanced control over the saw. Coupled with an ergonomic handle, the chainsaw is designed to fit comfortably in the user’s hand, reducing strain and improving handling.

In terms of safety, the CS 2137 is equipped with essential safety features such as a chain brake and a throttle lock. The chain brake acts as a crucial safety mechanism, stopping the chain instantly in emergency situations, while the throttle lock prevents accidental engagement of the chain during use. These safety features ensure that users can operate the chainsaw with confidence.

Moreover, the Jonsered CS 2137 incorporates an automatic chain oiler, which ensures that the chain receives the necessary lubrication during operation. This not only extends the life of the chain but also maintains optimal cutting performance. Users can adjust the oil flow rate according to their cutting needs, enhancing flexibility and efficiency.

Overall, the Jonsered CS 2137 is a well-rounded chainsaw that combines power, efficiency, and safety into one compact unit. Its thoughtful design and advanced technologies make it a valuable addition to any toolkit, whether for professional forestry work or home improvement projects.
