• Never start a chain saw indoors. Exhaust fumes can be dangerous.

• Before starting the saw make sure there are no people or animals nearby who might be put at risk.

• Place the saw on the ground and hold the rear handle down with your right foot. Grasp the front handle firmly using your left hand. Make sure the chain saw is steady and the chain is not touching the ground. Then grasp the starter handle with your right hand and pull the starter cord.

•Always store the chain saw and fuel away from any sources of sparks or naked flames, e.g. machines, electric motors, relays, switches, boilers, etc.

•Always store fuel in an approved container designed for that purpose.

•For longer periods of storage or for transport of the saw, the fuel and chain oil tanks should be emptied. Ask where you can dispose of waste fuel and chain oil at your local gas station.

8Never use any accessories other than those recommended in this manual. See the sections on ”Cutting equipment” and ”Technical data”.

The risk of accident is increased if you use the wrong cutting equipment or a chain that is not sharpened correctly. Using the wrong combi- nation of bar and chain can increase the risk of accidents!

51 specifications

The Husqvarna 51 is a well-regarded chainsaw that has made its mark in the world of outdoor power equipment. Renowned for its balance of performance and usability, the Husqvarna 51 is often favored by both amateur woodcutters and professionals alike. This versatile chainsaw is designed for a range of tasks, from light-duty pruning to more demanding woodcutting jobs.

One of the standout features of the Husqvarna 51 is its powerful 2.3 horsepower engine. This robust engine allows the saw to tackle larger cuts with ease, making it a reliable tool for any woodcutting needs. Coupled with a lightweight design, the chainsaw ensures reduced fatigue during prolonged use, enhancing user comfort and efficiency.

The Husqvarna 51 utilizes a simple yet effective starting system known as the Smart Start technology. This feature minimizes resistance in the starter cord, allowing for easier and quicker engine starts. Consequently, even less experienced users can confidently get the saw up and running without unnecessary frustration.

Another important characteristic of this model is its air injection system. This technology works by using centrifugal force to remove larger debris from the air filter before it reaches the engine. As a result, the filter stays cleaner for longer, reducing the frequency of maintenance and ensuring optimal engine performance. This system significantly prolongs the life of the chainsaw while maintaining high power levels.

The Husqvarna 51 also features an adjustable oil pump that allows operators to control oil flow as needed. This ensures proper lubrication of the chain and bar, which is critical for maintaining performance and extending the lifespan of the cutting components. The saw’s chrome-plated cylinder further contributes to durability by providing an added layer of resistance against wear and tear.

Safety is a priority with the Husqvarna 51, which comes equipped with an inertia-activated chain brake. This feature automatically stops the chain in the event of kickback, providing additional peace of mind to the user. The front hand guard and ergonomic handle design also enhance user control, contributing to a safer and more comfortable cutting experience.

Overall, the Husqvarna 51 stands out as a reliable, sturdy, and user-friendly chainsaw. Its blend of power, technology, and safety features makes it an ideal choice for a variety of cutting tasks, making it popular among both casual users and seasoned professionals. Whether you are trimming branches or cutting firewood, this chainsaw offers the performance you need for effective woodcutting.
