Starter device

!WARNING!

When the recoil spring is assembled in the starter housing, it is in tensioned position and can when treated carelessly, pop out and cause injuries.

Always be careful, when changing the recoil spring or the starter cord. Always wear safety goggles for eye protection.

Changing a broken or worn starter cord

• Loosen the screws, that hold the starter device against the crankcase and remove the starter device.

Pull out the cord approx. 30 cm and lift it up into the notch in the pulley. Zero-set

the recoil spring by letting the pulley rotate slowly backwards. Undo the screw in the centre of the pulley and remove the pulley.

• Insert and fasten a new starter cord in the pulley. Wind approx. 3 turns of the starter cord on to the pulley. Assemble the starter pulley against the recoil spring, so the end of the spring engages to the pulley. Fit the screw in the centre of the pulley. Carry the starter cord through the hole in the starter housing and the starter handle. Make a knot on the starter cord.

Tensioning the recoil spring

Lift the starter cord up in the notch on the starter pulley and turn the starter pulley 2 turns clockwise.

NOTE! Check that the starter pulley can be turned at least half a turn, when the starter cord is entirely pulled out.

Changing the broken recoil spring

Lift the starter pulley (see "Changing a broken or worn

starter cord").

The recoil spring is disassembled from the

starter device, with its inside facing down. Tap the starter lightly against a working bench or similar. If the spring pops out when assembling, it should be mounted again, out and in towards the centre.

Lubricate the recoil spring with thin oil. Assemble the

starter pulley, and tension the recoil spring.

Starter device assembly

Assemble the starter device, by pulling the starter cord out first, then place the starter against the crankcase. Then slowly release the starter cord so

that the pulley engages with the pawls.

• Assemble and tighten the screws, which hold the starter.

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.
