SAFETY INSTRUCTIONS Before using a new diamond chain saw • Please read the operator’s manual carefully. • Check the assembly and adjustment of the diamond chain, see chapter "Assembly". • Start the engine and check the carburettor setting, see chapter "Maintenance", section "Carburettor". If the carburettor setting is correct, the diamond chain shall stand still at idle speed. Setting of the idle speed is described in the Operator’s ...

SAFETY INSTRUCTIONS General safety precautions Work area safety • Keep work area clean and well lit. Cluttered or dark areas invite accidents. • Never use the machine indoors. Be aware of the dangers of inhaling the engine’s exhaust fumes. • Do not use the machine in bad weather, such as dense fog, rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground. • Never start t ...

SAFETY INSTRUCTIONS Fuel safety (Refuelling/Fuel mixture/Storage.) • Never refuel the machine while the engine is running. • Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil). • Move the machine at least 3 m from the refuelling point before starting it. • Never start the machine: - If you have spilt fuel on it. Wipe off the spillage and allow remaining fuel to evaporate. - If you h ...

SAFETY INSTRUCTIONS Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. Throttle lockout The throttle trigger lock is designed to prevent accidental operation of the throttle. When the lock (A) is pressed in this releases the throttle (B). The trigger lock remains pressed in as long as the throttle is pressed. When the grip on the handle is released the throttle trigger and the t ...

SAFETY INSTRUCTIONS Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released. • Press the throttle lockout and make sure it returns to its original position when you release it. • Check that the throttle control and throttle lockout move freely and that the return springs work properly. • Start the diamond chain saw and apply full throttle. Release the throttle control and c ...

SAFETY INSTRUCTIONS • Move the saw slowly backwards and forwards. Generally you should attempt to get the chain to cut over distances that are as small as possible. The partial pressure will then be higher and the cutting process will then be faster. In principle there are two ways to start the process of entering a thick object to be cut. Plunge-cut method Start by making a 10 centimetre deep cut in the wall using the lower part of the ti ...

SAFETY INSTRUCTIONS Cutting holes A common task for the diamond chain saw is making small openings in thick walls. First make the lower horizontal cut. Now make the two vertical cuts. Finish with the upper horizontal cut. The risk of jamming is then avoided. Bracing When cutting out large holes it is important that the piece to be cut out is braced so that it cannot fall against the operator. How to avoid kickback What is kickback? The word ...

SAFETY INSTRUCTIONS Diamond chains There are two basic types of diamond chain available on the market. When using a chain with double rakers, the chain can be fitted either way round. When using a chain with one raker, the chain should always be fitted the right way round. The raker should guide the segment at the right height in the cut. A) Drive link with raker B) Cutting link with diamond segment C - Drive link without washer Check the ...

ASSEMBLY How to tension the chain If the play between drive link and bar is bigger than 12 mm, the chain is too loose and must be tightened. Opening the adjust screw cover. Pull the handle backwards. Continue to move the handle down-wards until you start to tension the chain. Hold the bar upwards as you move the handle forward. Lock the chain tension by tightening the counter screw. Close the adjust screw cover. NOTE! A correctly tightened c ...

ASSEMBLY How to change the chain and rim Pull the handle backwards. Press the spring down on the chain tensioner handle. Unscrew the adjusting bar nut anti-clockwise. Remove the cover. Remove the bar and chain. Remove the spring holding the two "half-moons" using a screwdriver. Remove the "halfmoons", the cup guard, o-ring and the drive sprocket. Assemble the parts in the reverse order. Turn the bar when replacing the chain for maximum bar l ...

ASSEMBLY Tightening the bar nut If the bar and chain tensioner handle feel loose, the bar nut must be tightened to achieve the correct tension moment in the nut. This so that the bar does not fit loosely. Move the lever to its rear, lower position. Push in the spring on the chain tensioner handle and turn the bar nut clockwise by hand. Release the spring. Hold the bar upwards as you move the handle forward. Note that the arm's mechanical s ...

FUEL HANDLING Fuel CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two- stroke engine 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. Petrol • The lowest octane recommended is 90 (RON). If you run ...

STARTING AND STOPPING Before starting Decompression valve: Press the valve to reduce the compression in the cylinder. The decompression valve should always be used when starting. The valve automatically returns to its initial position when the machine starts. Stop switch: Make sure that the stop switch (STOP) is in the left position. Start throttle position - cold engine: Start throttle position and choke is obtained by pulling out the choke ...

MAINTENANCE Carburettor Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the running-in period, ask your dealer/service workshop (who will have a rev counter at their disposal) to adjust your carburettor. Functi ...

MAINTENANCE Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom. 2 The paper filter is accessible under cover B. This filter must be replaced/cl ...

MAINTENANCE Tensioning the recoil spring • Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. CAUTION! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out. Changing a broken recoil spring • Undo the bolt in the centre of the pulley and remove the pulley. • Bear in mind that the return spring lies tensioned in the starter housi ...
