FUEL HANDLING

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two- stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Always ensure there is adequate

!ventilation when handling fuel.

Petrol

•Use good quality unleaded or leaded petrol.

•CAUTION! Engines equipped with catalytic converters must be run on unleaded fuel mixtures. Leaded gasoline will destroy the catalytic converter and it will no longer serve its purpose. The green fuel cap on saws fitted with catalytic converters means that only unleaded gasoline can be used.

•The lowest recommended octane grade is 90 (RON). If you run the engine on a lower octane grade than 90 so- called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage.

•When working with continuous high revs (e.g. limbing) a higher octane is recommended.

Environment fuel

HUSQVARNA recommends the use of alkylate fuel, either Aspen two-stroke fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburettor adjustment may be necessary when changing the type of fuel (see the instructions under the heading Carburettor).

Running-in

Avoid running at a too high speed during the first 10 hours.

Two-stroke oil

•For best results and performance use HUSQVARNA two- stroke engine oil, which is specially formulated for our air- cooled two-stroke engines.

•Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW).

•Never use oil intended for four-stroke engines.

•A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters.

Mixing ratio

1:50 (2%) with HUSQVARNA two-stroke oil.

1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

Mixing

•Always mix the petrol and oil in a clean container intended for fuel.

•Always start by filling half the amount of the petrol to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of petrol.

•Mix (shake) the fuel mixture thoroughly before filling the machine’s fuel tank.

•Do not mix more than one month’s supply of fuel at a time.

•If the machine is not used for some time the fuel tank should be emptied and cleaned.

Chain oil

•We recommend the use of special oil (chain oil) with good adhesion characteristics.

•Never use waste oil. This results in damage to the oil pump, the bar and the chain.

•It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.

•In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components.

•Contact your service agent when choosing chain oil.

385XP specifications

The Husqvarna 385XP is a powerful and versatile chainsaw, designed to meet the demands of professional loggers and landowners alike. Known for its exceptional performance and reliability, this model is engineered for heavy-duty tasks, making it a popular choice among forestry professionals and those requiring robust cutting tools.

One of the standout features of the 385XP is its impressive engine performance. The chainsaw is equipped with a 70.7 cc, 4.2 horsepower X-Torq engine, which not only delivers high power output but also ensures lower fuel consumption and reduced emissions, making it environmentally friendly without sacrificing performance. The innovative X-Torq technology allows for optimal combustion, enabling the chainsaw to run smoother and more efficiently.

The design of the Husqvarna 385XP focuses on user comfort and control. It features an ergonomic handle that reduces vibrations, enhancing the operator's comfort during extended use. The chainsaw's anti-vibration system minimizes the impact of vibrations on the user's hands, allowing for longer periods of operation without fatigue. This is crucial for professionals who spend hours in the field.

Another important technological aspect of the 385XP is its easily adjustable chain tensioning system, which simplifies adjustments and maintenance. The side-mounted chain tensioner allows users to make quick changes without the need for additional tools, ensuring that they can focus on the job at hand rather than fussing with equipment.

The 385XP is equipped with a high-quality cutting bar and chain, designed for durability and efficiency. The chainsaw features a 20-inch bar that provides ample cutting capacity, allowing for precise cuts in a variety of wood types. Its sharp chain ensures clean cuts with minimal kickback, enhancing safety and effectiveness when tackling larger logs or dense trees.

Another notable feature is the Air Injection system, which utilizes centrifugal force to remove larger dust and debris particles before they reach the air filter. This prolongs the filter’s life and decreases maintenance requirements, allowing users to spend more time working rather than cleaning.

In conclusion, the Husqvarna 385XP is a reliable chainsaw that combines power, efficiency, and user comfort. Its cutting-edge technologies, durable construction, and ease of use make it an ideal choice for professionals in the forestry industry and skilled homeowners alike.
