User manual HUSQVARNA 235F

[. . . ] Operator′s manual 235R 235FR Please read the operator’s manual carefully and make sure you understand the instructions before using the machine. English KEY TO SYMBOLS Symbols WARNING!Clearing saws, brushcutters and trimmers can be dangerous!Careless or incorrect use can result in serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of the operator’s manual. [. . . ] If your machine is equipped with a catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture. Leaded petrol will destroy the catalytic converter. Use low-emission petrol, also known as alkylate petrol, if it is available. Transport and storage • Store and transport the machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or naked flames, for example, from electrical machinery, electric motors, electrical relays/ switches or boilers. When storing and transporting fuel always use approved containers intended for this purpose. When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out where to dispose of excess fuel. Ensure the machine is cleaned and that a complete service is carried out before long-term storage. The transport guard must always be fitted to the cutting attachment when the machine is being transported or in storage. Secure the machine during transport. • • • • • The lowest octane recommended is 90 (RON). If you run the engine on a lower octane grade than 90 socalled knocking can occur. This gives rise to a high engine temperature, which can result in serious engine damage. When working at continuous high revs a higher octane rating is recommended. • 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. Petrol, litre 5 10 15 20 Two-stroke oil, litre 2% (1:50) 0, 10 0, 20 0, 30 0, 40 3% (1:33) 0, 15 0, 30 0, 45 0, 60 • ! Fuel WARNING!Bear in mind the risk of fire, explosion and inhaling fumes. • • • CAUTION!The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol 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! [. . . ] Check that the spark plug is fitted with a suppressor. Clean the machine’s cooling system. Clean or replace the spark arrestor mesh on the muffler (only applies to mufflers without a catalytic converter). Clean the outside of the carburettor and the space around it. [. . . ]
