SAFETY INSTRUCTIONS Personal protective equipment MPORTANT INFORMATION • A clearing saw, brushcutter or trimmer used incorrectly or carelessly can become a dangerous tool, that can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the content of this manual. • When using a trimmer, personal protective equipment approved by the appropriate authorities must be used.
SAFETY INSTRUCTIONS 4. Vibration damping system Your machine is equipped with a vibration damping system, which is designed to give as vibration-free and comfortable use as possible. Use of incorrectly wound cord or incorrect cutting equipment increases the level of vibration. The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/ cutting equipment and the machine’s handle unit. 5.
SAFETY INSTRUCTIONS Control, maintenance and service of the machine‘s safety equipment IMPORTANT INFORMATION • All service and repairs to the machine require special training. • This applies especially to the machine‘s safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop. • The purchase of one of our products guarantees that professional repair and servicing will be carried out on it.
SAFETY INSTRUCTIONS 6. Cutting equipment The section describes how through correct maintenance and through using the right type of cutting equipment you can: • Obtain maximum clearing capacity. • Increase the service life of the cutting equipment. Two basic rules: 1)Only use the cutting and guard equipment we recommend! See chapter “Technical data“. 2)Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced. 7.
SAFETY INSTRUCTIONS General safety instructions IMPORTANT INFORMATION • The machine is only designed for trimming grass. • The only accessories to be used with the engine unit as a drive source are the cutting units we recommend in the chapter “Technical data“. Fuel safety • Never fill the machine while the engine is running. Always stop the engine and let it cool for a few minutes before refuelling.
SAFETY INSTRUCTIONS General working instructions Basic working techniques IMPORTANT INFORMATION • Always trim at full throttle. • This section takes up the basic safety precautions for working with the trimmer. • Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage.
SAFETY INSTRUCTIONS Clearing • The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. NOTE! This technique increases the wear on the cord. Trimming • The trimmer is ideal to cut grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting.

ASSEMBLY Assembling the loop handlebar • Unscrew the handle and plastic cover from the handlebar bracket. • Place the loop handlebar with the handlebar holder on the handlebar bracket. Fit the handle and plastic cover. Do not tighten too tight. • Put on the harness and hang the trimmer in the suspension hook. Now finely adjust so that the trimmer gives a comfortable working position when it‘s attached to the harness. Tighten the handle.
ASSEMBLY Assembling other guards and cutting equipment Assembling and dismantling the two-part shaft (225LD, 227LD) • Fit the guard (A) intended for use with the trimmer head. Secure using four bolts (L) and the support plate (M) as shown in the diagram. Assembling: • Make sure the handle is loose. A L • Fit the disc drive (B) on the output axle. B C M • Guide the cut-out on the lower section of the shaft into the coupling‘s locking plate on the upper section of the shaft.
FUEL HANDLING Fuel mixture NOTE! The machine is fitted with a two-stroke engine and must always be run on a mixture of gasoline 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. ! WARNING! Always provide good ventilation when handling fuel.
START AND STOP Control before starting For reasons of safety follow these recommendations! • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked. • Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm. • Check that the trimmer head and spray guard are not damaged or cracked.
MAINTENANCE Carburetor 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 carburetor for optimum operating conditions.
MAINTENANCE Final setting of the idling speed T Correctly adjusted carburetor 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, counter-clockwise 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 your machine is fitted with a catalytic converter. To maintain as low operating temperature as possible the engine is equipped with a cooling system. The cooling system consists of: 1. An air intake on the starter unit. 2. Cooling fins on the flywheel. 3. Cooling fins on the cylinder 4. Cylinder cover (leads cold air onto the cylinder).
MAINTENANCE Spark plug The condition of the spark plug is affected by: • An incorrect carburetor setting. • An incorrect fuel mixture (too much or faulty oil). • A dirty air filter. 0,5 mm These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties. If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first. If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.
