MAINTENANCE

Adjustment of the oil pump.

Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.

Recommended settings:

Bar 15": Position 1

Bar 16"-18": Position 2

Bar 20"-24": Position 3

 

!

WARNING! The engine must not be

 

running when making adjustments.

 

 

 

 

 

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Air guide plate.

3Fins on the flywheel.

4Cooling fins on the cylinder.

5Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

”Air Injection” centrifugal cleaning

Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.

IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburettor compartment.

Winter use

Running problems can occur when using the machine in the cold and snowy conditions caused by:

Too low engine temperature.

Icing of the air filter and carburettor. Special measures are therefore often required:

Partly mask the air inlet on the starter to increase the working temperature of the engine.

Temperature 0°C or colder:

The cylinder cover is designed so it can be adjusted for running in cold weather, so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.

455, 455e, 460, 465 specifications

The Husqvarna 460 and 455 series chainsaws are some of the most popular models in their class, recognized for their reliability, performance, and advanced technology. These machines are designed to meet the demands of both professionals and enthusiasts who require powerful tools for cutting firewood, felling trees, or performing tree maintenance.

The Husqvarna 460 is equipped with a robust 60.3 cc engine that delivers impressive power and efficiency. With a power output of approximately 3.6 kW, this chainsaw is capable of handling ambitious cutting tasks with ease. The design of the 460 includes a low-vibration system that significantly reduces operator fatigue during extended use. This is achieved through effective isolating features that dampen vibrations transferred to the user's hands, allowing for more comfortable operation over longer periods.

One of the standout features of the Husqvarna 460 is its X-Torq engine technology. This innovative design reduces fuel consumption by up to 20% while also decreasing harmful exhaust emissions. This is increasingly important for environmentally conscious users, as it allows for a greener operation without compromising performance. The chainsaw is also equipped with an air injection system that effectively removes larger particles from the air before they reach the filtration system, ensuring cleaner air intake and extending the lifespan of the air filter.

On the other hand, the Husqvarna 455 Rancher is another exceptional model known for its versatility and robust design. Featuring a slightly smaller 55.5 cc engine, it offers a solid power output of around 2.6 kW, making it suitable for a wide range of tasks from cutting firewood to clearing brush. The 455 Rancher shares many of the same technological advancements as the 460, including the X-Torq engine and low-vibration technology, providing users with similar benefits in terms of efficiency and comfort.

Both models feature an adjustable oil pump for better chain lubrication, ensuring smooth operation and prolonging the chain's life. Additionally, the easy access air filter and tool-less chain tensioning allow for quick maintenance and adjustments in the field, making them user-friendly choices.

Overall, the Husqvarna 460 and 455 series chainsaws combine power, efficiency, and advanced technology, catering to the needs of both casual users and professionals alike. Their thoughtful design and robust performance establish them as reliable tools in any cutting task, making them a top choice for those in need of high-quality chainsaws.
