MAINTENANCE

High speed jet H

At the factory the engine is adjusted at sea level. When working at a high altitude or in different weather conditions, temperatures and atmospheric humidity, it may be necessary to make minor adjustments to the high speed jet.

CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder.

When test run at the factory, the high speed jet is set so that the engine satisfies the applicable legal requirements at the same time as achieving maximum performance. The carburetor’s high speed jet is then locked using a limiter cap in the fully screwed out position. The limiter cap limits the potential to adjust the high speed jet to at most half a turn.

CAUTION! There is an integrated speed governor in the ignition system that limits the maximum speed to 13600 rpm. The maximum speed will not exceed 13600 rpm when the high speed jet is adjusted (screwed in). When the speed governor is activated, you will get the same sound experience as when the chain saw 4-cycles.

To adjust the carburetor correctly you should contact a mechanic with access to a rev counter.

CAUTION! As the spark is cut off, the rev counter does not show speeds higher than 13600 rpm.

Correctly adjusted carburetor

When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difficulties and poor acceleration. If the H-jet is set too lean the machine will have less power, poor acceleration and could suffer damage to the engine.

Checking, maintaining and servicing chain saw safety equipment

Note! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment. If your machine fails any of the checks described below we recommend you to contact our servicing dealer.

Chain brake and front hand guard

Checking brake band wear

Brush off any wood dust, 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 mm (0,024 inch) thick at its thinnest point.

Checking the front hand guard

Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.

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

570, 575XP specifications

The Husqvarna 570 and 575XP chainsaws are remarkable tools designed for professional logger and forestry applications. Built for performance, durability, and ease of use, both models are engineered to handle the demands of heavy-duty cutting tasks while delivering outstanding power-to-weight ratios.

One of the standout features of the Husqvarna 570 is its X-Torq engine technology, which is designed to provide increased power while reducing fuel consumption and emissions. This engine technology allows the chainsaw to operate more efficiently, making it an environmentally friendly choice for users who are conscious about their impact on nature. The 575XP model also comes equipped with the X-Torq engine, delivering exceptional performance in a compact design.

Both models feature Husqvarna’s Air Injection system, which helps to minimize wear and tear by filtering out larger particles before they reach the air filter.

The chainsaws come with a low-vibration system, which significantly reduces vibrations felt by the operator, making extended use more comfortable. The front and rear handles are designed for optimal grip, allowing for better maneuverability and reducing operator fatigue during prolonged cutting sessions.

Another key characteristic is the quick-release air filter, which allows for easy access for maintenance. This feature is particularly beneficial for professionals who need to ensure their equipment remains in peak condition.

In terms of safety, both models include a chain brake that provides instant stopping capabilities for added security during operation. This is a crucial feature when working in potentially hazardous environments.

With their combination of innovative technologies, ergonomic design, and robust performance, the Husqvarna 570 and 575XP chainsaws stand out in the market as reliable tools for professionals needing efficiency and power.
