SAFETY INSTRUCTIONS 2. Stop switch The stop switch should be used to stop the engine. 4. Anti-vibration system Your machine is equipped with an anti-vibration system that has been designed to give as vibration-free and comfortable usage as possible. The use of incorrectly wound cord or blunt, incorrect cutting equipment (incorrect type or incorrectly sharpened, see section “Filing the blade”) increases the level of vibration.
SAFETY INSTRUCTIONS 6. Muffler The muffler is designed to give the lowest possible noise level and to direct the engine‘s exhaust fumes away from the operator. Muffler fitted with catalytic converter is also designed to reduce harmful exhaust components. In countries that have a warm and dry climate the risk of fire is obvious. We have therefore fitted certain mufflers with a spark arrest screen. Make sure that your muffler is fitted with this kind of screen.

FUEL HANDLING Fuel Mixture NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of petrol and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel. • Always mix petrol and oil in a clean container intended for petrol.
START AND STOP Control before starting For reasons of safety follow these recommendations! • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found. • Check that the support flange is not cracked due to fatigue or due to being tightened too much.
START AND STOP For throttle handles with a start throttle lock: Set the throttle to the start position by first pressing the throttle lock and the throttle trigger, then pressing the start throttle button (A). Then release the throttle lock and the throttle trigger, followed by the start throttle button. The throttle function is now activated. To return the engine to idle, press the throttle lock and throttle trigger again.
MAINTENANCE Carburettor Basic setting Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburettor for optimum operating conditions.
MAINTENANCE Final setting of the idling speed T Correctly adjusted carburettor Adjust the idling speed with the screw T, If it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting attachment starts to rotate/ move. Then turn, counterclockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position.
MAINTENANCE Muffler Cooling system NOTE! Some mufflers are fitted with a catalytic converter. See “Technical data” to see whether you clearing saw is fitted with a catalytic converter. To maintain as low operating temperature as possible the engine is equipped with a cooling system. The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user.
MAINTENANCE Air filter Spark plug The air filter should be cleaned regularly removing dust and dirt to avoid: • carburettor malfunction • starting problems • reduced engine power • unnecessary wear to engine parts • abnormal fuel consumption The condition of the spark plug is affected by: • An incorrect carburettor setting. • An incorrect fuel mixture (too much or faulty oil). • A dirty air filter. Clean the filter after every 25 hours or more regularly if operating conditions are exceptionally dusty.
MAINTENANCE Sharpening the clearing blade ! WARNING! Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback. • See the cutting equipment’s packaging for correct filing instructions. • A correctly sharpened blade is a prerequisite for working efficiently and to avoid unnecessary wear to the blade and clearing saw. • Make sure that the blade is well supported when you use the file. Use a 5.5 mm round file with a file holder. • The sharpening angle is 15°.
MAINTENANCE Weekly maintenance Monthly maintenance 1 1.Check the starter, the starter cord and the return spring. 2.Make sure that the vibration damping elements are not damaged. 3.Clean the outside of the spark plug. Remove and check the electrode gap. Adjust the gap to 0.5 mm or change the spark plug. 1.Clean the fuel tank. 2 3 6.Clean the carburettor area. 7.Clean the cooling fins on the cylinder and check that the air intake in the starter unit is not blocked. 8.
