Brush off any sawdust, resin and dirt from the

chain brake and clutch drum. Dirt and wear can impair operation of the brake.

Regularly check that the brake band is at least 0.6

mmthick at its thinnest point.

2 Checking the front hand guard

AMake sure the

FRONT HAND GUARD is not damaged and

that there are no visible defects such as cracks.

B Move the front hand guard forwards and back to make sure it runs freely and that it is securely anchored to the clutch cover.

3 Checking the inertia brake release

Hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar falls onto the stump.

When the bar hits the stump the brake should be applied.

4Checking the brake trigger

Place the chain saw on a firm surface and start it.

Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop.

Grasp the saw firmly, wrapping your fingers and thumbs around the handles.

The chain should stop immediately.

346XP 351 specifications

The Husqvarna 346XP and 351 chainsaws are celebrated models within the Husqvarna lineup, recognized for their excellence in performance, efficiency, and ease of use. Designed predominantly for professional use, these chainsaws incorporate advanced technology and ergonomic features that cater to the needs of tree care specialists, landscapers, and serious woodworkers.

One of the standout features of the Husqvarna 346XP is its lightweight design, which allows for easy maneuverability and reduced fatigue during extended use. Weighing around 10.8 pounds, the chainsaw is equipped with a powerful 50.1cc, 2.8 horsepower engine, delivering exceptional cutting performance while maintaining efficient fuel consumption. The model comes equipped with a 15 to 18-inch guide bar, providing versatility for various cutting tasks, from limbing to felling small trees.

The 351 model offers similar performance metrics but is designed slightly differently, featuring an improved air injection system for cleaner operation. This system actively collects debris before it reaches the air filter, extending the service intervals and enhancing engine life. The powerful 51.7cc engine on the 351 provides a higher power output compared to the 346XP, suited for even the most demanding cutting jobs.

Both chainsaws utilize Husqvarna’s X-Torq engine technology, which reduces fuel consumption by up to 20% while lowering emissions. This not only promotes environmental sustainability but also translates into cost savings for users. The LowVib technology integrated into both models minimizes vibrations, ensuring a more comfortable experience and reducing operator fatigue.

Enhanced safety features are also paramount in both chainsaws. The inertia-activated chain brake activates quickly in the event of a kickback, providing an additional layer of protection. An adjustable oil pump allows users to control the lubrication rate, optimizing the chainsaw's performance based on the type of work being performed.

The ergonomic design of the handles enhances grip and control, allowing for precision cutting. These chainsaws are user-friendly, catering to both experienced operators and those new to chainsaw work. Overall, the Husqvarna 346XP and 351 represent a perfect blend of power, technology, and comfort, making them reliable choices for professional and serious amateur users alike.
