Tighten it. • Unscrew the knob from the handlebar mounting. • Position the handlebar as shown.
ASSEMBLY Assembling the cutting equipment ! WARNING! When fitting the cutting attachment it is extremely important that the raised section on the drive disc/support flange engages correctly in the centre hole of the cutting attachment. If the cutting attachment is fitted incorrectly it can result in serious and/or fatal personal injury. • 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.
ASSEMBLY Fitting the blade guard and saw blade Fitting the trimmer guard and trimmer head Trimmy SII • • The blade guard (A) is fitted using 4 screws (L) as shown. L A 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). Bend the guard around the shaft and tighten it with the bolt (L) on the opposite side of the shaft. Use the locking pin (C).
ASSEMBLY Fitting other guards and cutting attachments • Fit the trimmer guard/combination guard (A) intended for use with the trimmer head/plastic blades. Hang the trimmer guard/combination guard (A) on the two hooks on the plate holder (M). Bend the guard around the shaft and tighten it with the bolt (L) on the opposite side of the shaft. Use the locking pin (C). Place the locking pin in the groove on the screw head and tighten. See diagram.
ASSEMBLY 2 Grass clearing 4 Adjust the height of the suspension hook as described in the instructions for the standard harness. (Forestry clearing) 5 If you need to lower the suspension hook, for trimming for example, move the suspension strap (A) to the lower mounting point on the backplate. 6 The elastic strap (B) can be tightened to transfer more load from the shoulder straps to the hip strap.
FUEL HANDLING Fuel safety Gasoline Never start the machine: 1 If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. 2 If 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. 3 If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
FUEL HANDLING Fueling 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. 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 Start throttle: (FC 2145, FC 2145 S, FC 2145 W, BC 2145, CC 2145) Heated handles (FC 2145 W) Set the throttle to the start position by moving the choke control to the choke position and then returning it to its original position. Models equipped with heating elements in the handles have an on/off switch on the throttle handle to control the heat. Both the left and right handles have heating elements that automatically maintain a temperature of roughly 70° when the heat is turned on.
WORKING TECHNIQUES General working instructions 6 Keep a good balance and a firm foothold. 7 Always hold the machine with both hands. Hold the machine on the right side of your body. 8 Keep the cutting attachment below waist level. 9 Switch off the engine before moving to another area. Fit the transport guard before carrying or transporting the equipment any distance. IMPORTANT! This section describes the basic safety precautions for working with clearing saws and trimmers.
WORKING TECHNIQUES ! WARNING! Watch out for thrown objects. Always wear approved eye protection. Never lean over the cutting attachment guard. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. • On sloping ground you should work along the slope. It is much easier to work along a slope than it is to work up and down it. • You should plan the strip so that you avoid going over ditches or other obstacles on the ground.
WORKING TECHNIQUES • To fell a tree forwards, the bottom of the tree should be pulled backwards. Pull the blade backwards with a quick, firm movement. • Large stems must be cut from two sides. First determine which direction the stem will fall. Make the first cut on the felling side. Then finish cutting the stem from the other side. Adjust the cutting pressure to match the size of the stem and the hardness of the wood. Small stems require more pressure, while large stems require less pressure.
WORKING TECHNIQUES Grass trimming with a trimmer head Sweeping • The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro. • When cutting and sweeping you should use full throttle to obtain the best results. Trimming • Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace.
MAINTENANCE Carburetor Basic setting 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 Fine adjustment of the idle speed T Adjust the idle speed using the idle adjustment screw T, if it is necessary to readjust. First turn the idle adjustment screw T clockwise until the cutting attachment starts to rotate. Then turn the screw anticlockwise until the cutting attachment stops. The idle speed is correctly adjusted when the engine will run smoothly in every position. The idle speed should also be well below the speed at which the cutting attachment starts to rotate.
MAINTENANCE Adjusting the start throttle speed (BC 2145, CC 2145) CAUTION! Never use a machine with a defective muffler. The correct start throttle speed is set by means of an adjuster on the rear of the handle next to the cable. Use this screw (5 mm Allen screw) to increase or decrease the start throttle speed. ! WARNING! Mufflers fitted with catalytic converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin.
MAINTENANCE Cleaning the air filter Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Drive shaft The drive shaft must be greased every three months during full-time use. Contact your dealer if you are uncertain about the procedure. Spark plug The spark plug condition is influenced by: An oiled foam plastic filter (available as an accessory) must be used if the machine is operated in extremely dusty conditions.
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 carburetor. IMPORTANT! Use only JONSERED replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by JONSERED.
