FUEL HANDLING

Fuel

Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke 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.

 

 

 

 

 

Gasoline

•Use good quality unleaded gasoline.

•The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 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.

Running-in

Avoid running at a too high speed for extended periods 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.

Mixing ratio

1:50 (2%) for all engines.

Mixing

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

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

•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.

14 – English

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 32°F (0°C) 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.

Fueling

WARNING! Taking the following

!precautions, will lessen the risk of fire:

Do not smoke and do not place any hot objects in the vicinity of fuel.

Always stop the engine and let it cool for a few minutes before refuelling.

When refuelling, open the fuel cap slowly so that any excess pressure is released gently.

Tighten the fuel cap carefully after refuelling.

Always move the machine away from the refuelling area before starting.

Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel filter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always fill the chain oil tank and fuel tank at the same time.

WARNING! Fuel and fuel vapor are

! highly flammable. Take care when handling fuel and chain oil. Be aware of the risks of fire, explosion and those associated with inhalation.

Fuel safety

•Never refuel the machine while the engine is running.

•Make sure there is plenty of ventilation when refuelling or mixing fuel (gasoline and 2-stroke oil).

•Move the machine at least 10 ft (3 m) from the refuelling point before starting it.

•Never start the machine:

1If you have spilled fuel or chain oil on the machine.Wipe off the spillage and allow remaining fuel to evaporate.

2If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

3If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

The Husqvarna 235 and 240 chainsaws are compact, lightweight power tools designed for homeowners and occasional users seeking reliability and performance. Known for their ease of use and versatility, both models are ideal for tasks such as pruning, cutting firewood, and clearing small trees.

One of the main features of the Husqvarna 235 and 240 is their X-Torq engine technology. This innovation reduces fuel consumption by up to 20% while also cutting emissions by approximately 75%. This not only makes the chainsaws environmentally friendly but also saves users on fuel costs over time. The engine's design also enhances torque, providing ample power for cutting through wood efficiently.

Both models come equipped with an inertia-activated chain brake, enhancing safety by preventing unwanted chain movement in case of a kickback. The chain brake is a critical feature for novice users, promoting confidence while operating the chainsaw. This focus on safety extends to the easy-to-reach throttle lockout and combined choke/stop control, allowing for simpler starting procedures.

The Husqvarna 235 and 240 feature an adjustable oil pump, which enables users to control the oil flow to the chain according to their specific needs. This functionality not only prolongs the life of the chain and bar but also helps maintain cutting performance, ensuring smoother operation and reduced wear.

These chainsaws also have ergonomic designs, with comfortable handles that minimize vibrations and allow for prolonged use without fatigue. The lightweight structure makes them easily maneuverable, which is particularly beneficial for tasks that require precision casing or reaching difficult areas.

Another noteworthy characteristic is the Tool-less chain tensioning system. This feature allows users to adjust the chain tension quickly and without the need for additional tools, simplifying maintenance and enhancing user experience.

Overall, the Husqvarna 235 and 240 chainsaws are excellent choices for homeowners seeking reliable, efficient, and easy-to-use tools for light to moderate cutting tasks.
