MAINTENANCE

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.

Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efficient cooling of the engine and the catalytic converter unit.

”Air Injection” centrifugal cleaning

Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed 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 carburetor 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 carburetor. Special measures are therefore often required:

•Preheat the intake air to the carburetor by using the heat from the cylinder.

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

Fitting the winterising kit

Cut out a hole using a knife as shown.

Fit the winter cover in the cylinder cover.

Temperature 0°C (32°F) or colder:

Move the cover from position A to position B so that preheated air from the cylinder can pass into the carburettor compartment and prevent, e.g. the air filter icing up again. When fitting the winter cover in position B the centrifugal cleaning nozzle is blocked. This measure requires the air filter to be cleaned more regularly.

1152353-95, 570 EPA III, 576 XP EPA III specifications

The Husqvarna 576 XP EPA III and 570 EPA III chainsaws exemplify innovation in outdoor power equipment, designed for the demanding user who requires high performance and reliability. These models are ideal for professional loggers and landowners alike, combining power, efficiency, and advanced technology.

One of the standout features of the Husqvarna 576 XP EPA III is its powerful 72.2cc engine, which delivers exceptional cutting performance while maintaining low fuel consumption. This model incorporates the X-Torq technology, which reduces fuel consumption by up to 20% and decreases harmful exhaust emissions by up to 75%. This makes the 576 XP EPA III not only high-performing but also environmentally friendly, meeting stringent EPA emission requirements.

The 570 EPA III, slightly smaller at 65.1cc, still boasts impressive power and torque, making it suitable for a variety of cutting tasks. This model is also equipped with the X-Torq technology, offering fuel efficiency and reduced emissions. It’s tailored for users who need a reliable chainsaw for medium to heavy-duty jobs, providing both power and ease of use.

Both models feature an Air Injection system that uses centrifugal force to remove larger dust and debris particles before they reach the air filter. This prolongs the life of the engine and reduces maintenance, enabling users to focus on the job at hand rather than frequent servicing.

Additionally, the Husqvarna 576 XP EPA III includes Smart Start technology, which ensures quick and effortless starting. The fuel pump and choke are designed to work in harmony, making it easier to start the saw with minimal effort.

Both chainsaws are designed with an ergonomic handle that provides excellent grip and comfort, reducing fatigue during extended use. The LowVib technology minimizes vibrations, further enhancing user comfort and control.

In terms of safety, both models are equipped with a chain brake that quickly stops the chain in the event of a kickback, protecting the user.

Overall, the Husqvarna 576 XP EPA III and 570 EPA III chainsaws are high-performance tools that combine advanced technology with user-friendly design, making them suitable for professionals and enthusiasts alike who demand efficiency and reliability in every cut.
