mmthick at its thinnest point.

2 Checking the front hand guard

A Make 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.

Start the chain saw and place it on firm ground. Make sure the chain does not touch the ground or any other object.

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

Apply full throttle and activate the chain brake by tilting your wrist forward onto the front hand guard. Do not let go of the front handle.

The chain should stop immediately.

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.
