GENERAL SAFETY PRECAUTIONS Important Personal protective equipment IMPORTANT! IMPORTANT! The machine is only designed for trimming grass, grass clearing and/or forestry clearing. A clearing saw, brushcutter or trimmer can be dangerous if used incorrectly or carelessly, and can cause serious or fatal injury to the operator or others. It is extremely important that you read and understand the contents of this operator’s manual.
GENERAL SAFETY PRECAUTIONS BOOTS Wear boots with steel toe-caps and non-slip sole. control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting. CLOTHING Wear clothes made of a strong fabric and avoid loose clothing that can catch on twigs and branches. Always wear heavy, long pants.
GENERAL SAFETY PRECAUTIONS be checked. See instructions under the heading Maintenance. Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier. Use of incorrectly wound cord or an incorrect cutting attachment increases the level of vibration. See instructions under the heading Cutting equipment. Stop switch Use the stop switch to switch off the engine.
GENERAL SAFETY PRECAUTIONS cutter. Certain harnesses also have a quick release fitted to the support hook. If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Check that the harness straps are correctly positioned. Once the harness and machine have been adjusted, check that the harness quick release works correctly.
GENERAL SAFETY PRECAUTIONS operate the socket spanner when loosening or tightening the nut. The nylon lining inside the locking nut must not be so worn that you can turn it by hand. The lining should offer a resistance of at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times. ! ! WARNING! Always stop the engine before doing any work on the cutting attachment. This continues to rotate even after the throttle has been released.
GENERAL SAFETY PRECAUTIONS Keep the correct setting on the saw blade! Follow our instructions and use the recommended setting tool. An incorrectly set saw blade increases the risk of jamming and blade thrust, and damage to the saw blade. A correctly sharpened blade is essential for working efficiently and to avoid unnecessary wear to the blade and brush cutter. Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
GENERAL SAFETY PRECAUTIONS Trimmer head IMPORTANT! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration. • Only use the recommended trimmer heads and trimmer cords. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the recommended cutting attachment. See the chapter on Technical data.

If the cutting attachment is fitted incorrectly it can result in serious and/or fatal personal injury.
ASSEMBLY • Centre the metal cup (P) on the drive disc’s blade guide. • Turn the output shaft until one of the holes in the drive disk aligns with the corresponding hole in the gear housing. • Insert the locking pin (C) in the hole to lock the shaft. • Position the blade (D) with the drive disk (B). Make sure that the blade is centered by fitting it to the guide on the drive disk. • Fit the support flange (F) on the output shaft so that it rests against the blade.
ASSEMBLY spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut. • Screw on the trimmer head (H) in the opposite direction to the direction of rotation. H C Fitting the trimmer guard and trimmer head Trimmy SII • Fit the correct trimmer guard (A) for use with the trimmer head. Hang the trimmer guard/combination guard (A) on the two hooks on the plate holder (M).
ASSEMBLY • Screw on the trimmer head/plastic blades (H) in the opposite direction to the direction of rotation. • To dismantle, follow the instructions in the reverse order. Adjust the height using the strap on the harness for the support hook. Adjusting the harness and brush cutter ! WARNING! When using a brush cutter it must always be hooked securely to the harness. Otherwise you will be unable to control the brush cutter safely and this can result in injury to yourself or others.

FUEL HANDLING Fuel safety Never start the machine: 1 If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilt 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. 3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines. catalytic converter (see chapter on Technical data) always use a good quality unleaded petrol/oil mixture.
FUEL HANDLING Fuelling 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. WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel.
STARTING AND STOPPING Check before starting • 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.
STARTING AND STOPPING engine to idle, press the throttle lockout and throttle trigger again. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. Start throttle: (FC 2145, FC 2145 S, FC 2145 W, BC 2145, CC 2145) Set the throttle to the start position by moving the choke control to the choke position and then returning it to its original position.
WORKING TECHNIQUES General working instructions yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury. IMPORTANT! This section describes the basic safety precautions for working with brush cutters and trimmers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.
WORKING TECHNIQUES ! WARNING! Neither the operator of the machine nor anyone else may attempt to remove the cut material while the engine is running or the cutting equipment is rotating, as this can result in serious injury. • Work systematically to and fro across the area, clearing a width of around 4-5 m on each pass. This exploits the full reach of the machine in both directions and gives the operator a convenient and varied working area to work in. • Clear a strip around 75 m long.
WORKING TECHNIQUES • To fell to the left, the bottom of the tree should be pushed to the right. Tilt the blade and bring it diagonally down to the right, exerting firm pressure. At the same time push the stem using the blade guard. Cut with the area of the blade between 3 o’clock and 5 o’clock. Apply full throttle before advancing the blade. • To fell to the right, the bottom of the tree should be pushed to the left. Tilt the blade and bring it diagonally up to the right.
WORKING TECHNIQUES Grass clearing using a grass blade can also damage sensitive bark on trees and bushes, and damage fence posts. • • • • • • • • • Grass blades and grass cutters must not be used on woody stems. A grass blade is used for all types of tall or coarse grass. The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-toright is the return stroke.
MAINTENANCE Carburettor Your Jonsered product has been designed and manufactured to specifications that reduce harmful exhaust fumes. The engine will be run in after it has used 8-10 tanks of fuel. To ensure that the engine runs at peak performance and produces as little harmful exhaust fumes as possible after the running-in period, ask your dealer/service workshop (which has a rev counter for this purpose) to adjust your carburettor.
MAINTENANCE 2 Press the start throttle lock as described under the heading Starting and stopping. 3 If the start throttle speed is too low (below 4000 rpm), turn the adjuster screw A clockwise until the cutting attachment starts to rotate. Then turn A clockwise a further 1/2 turn. 4 If the start throttle speed is too high, turn the adjuster screw A anticlockwise until the cutting attachment stops. Then turn adjuster screw A clockwise a further 1/2 turn.
MAINTENANCE Cleaning the air filter Bevel gear Remove the air filter cover and take out the filter. Blow clean with compressed air. The bevel gear is filled with the right amount of grease at the factory. However, before using the machine you should check that the bevel gear is filled 3/4 full with grease. Use JONSERED special grease. The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
MAINTENANCE Winter use Running problems can occur when using the machine in the cold and snowy conditions caused by: • Too low engine temperature. • Icing of the air filter and carburettor. Special measures are therefore often required: • Partly mask the air inlet on the starter to increase the working temperature of the engine. • Preheat the intake air to the carburettor by using the heat from the cylinder.
MAINTENANCE Maintenance schedule The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. The user must only carry out the maintenance and service work described in this Operator’s Manual. More extensive work must be carried out by an authorized service workshop.
