SAFETY INSTRUCTIONS

1Undo the bar nuts that

hold the clutch cover and chain brake, using the combination spanner. Then tighten the nuts by hand as tight as you can.

2 Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it not hang slack on the underside of the bar.

3 Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it is not slack on the bottom of the bar.

The position of the chain tensioning screw varies from model to model. See the” What is what” section to find out where it is on your saw.

4 Lubricating cutting equipment

Poor lubrication of cutting equipment may cause the chain to snap and lead to serious, even fatal injuries.

Prolonged inhalation of exhaust gases from the engine, chain lubrication oil mist and/or saw dust can be unhealthy.

A Chain oil

•Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather.

•As a chainsaw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage.

•If our own chain oil is not available, standard chain oil is recommended.

•In areas where oil specifically for lubrication of saw chains is unavailable, ordinary EP 90 transmission oil may be used.

•Never use waste oil!

This is dangerous for yourself, the saw and the environment.

BFilling with chain oil

• All our chain saws have an automatic chain lubrication

system. On some models the oil flow is also adjustable.

• The sizes of the chain oil tank and fuel tank have been chosen so that the saw will run out of fuel before running out of oil. This means that you should never run with a dry chain.

However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburettor as recommended (a weak mixture may mean that the fuel lasts longer than the oil). You should also use the recommended cutting equipment (a bar that is too long will use more chain oil). The above conditions also apply to models with an adjustable oil pump.

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.
