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 0.024 inch (0.6 mm) 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.

372XP EPA II, 365 EPA I specifications

The Husqvarna 365 EPA I and 372XP EPA II are two powerful chainsaws designed for serious woodcutting enthusiasts and professionals alike. Known for their robust performance, advanced technologies, and ergonomic design, these models are built to handle demanding tasks with ease.

The Husqvarna 365 EPA I is celebrated for its reliability and efficiency. It features a high-performance X-Torq engine that reduces fuel consumption by 20% and emissions by 75%, making it an environmentally friendly choice. The engine delivers impressive power output, ensuring that the saw can tackle tough cuts without compromising performance. Weighing in at just over 12 pounds, the 365 provides a perfect balance of power and maneuverability.

One of the standout features of the 365 is its Air Injection centrifugal air cleaning system, which helps to keep the air filter cleaner for longer periods. This results in reduced maintenance and improved performance, allowing users to focus on their cutting tasks rather than worrying about frequent cleaning. The chainsaw is also equipped with an adjustable oil pump, providing the user with the ability to control lubrication for better chain life and efficiency.

On the other hand, the Husqvarna 372XP EPA II takes performance to the next level. It boasts a larger displacement engine than the 365, offering enhanced power for professional applications. With the same X-Torq technology, it combines power and fuel efficiency, making it a great tool for heavy-duty tasks such as felling large trees or bucking heavy logs.

The 372XP is designed with an emphasis on ergonomics, featuring a slim body and excellent weight distribution. This makes it comfortable to handle, even during prolonged use. The chainsaw also comes with an innovative Smart Start system, which reduces resistance in the starter cord, ensuring easier starts every time. The adjustable oil pump feature is retained, allowing for precision control over the amount of oil delivered to the chain.

Both models reflect Husqvarna's commitment to quality and innovation, featuring durable components built to withstand the rigors of professional use. With their combination of advanced engine technology, design ergonomics, and ease of use, the Husqvarna 365 EPA I and 372XP EPA II remain top choices among chainsaw users looking for reliable performance and longevity.
