MAINTENANCE Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efficient cooling of the engine and the catalytic converter unit. "Air Injection" centrifugal cleaning Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan. 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. Special measures are therefore often required: • Preheat the intake air to the carburetor by using the heat from the cylinder. • Partly mask the air inlet on the starter to increase the working temperature of the engine. Fitting the winterising kit Cut out a hole using a knife as shown. IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburetor compartment. Fit the winter cover in the cylinder cover. THIS SIDE VISIBLE 537 21 05 XX Temperature 0°C (32°F) or colder: Move the cover from position A to position B so that preheated air from the cylinder can pass into the carburettor compartment and prevent, e.g. the air filter icing up again. When fitting the winter cover in position B the centrifugal cleaning nozzle is blocked. This measure requires the air filter to be cleaned more regularly. 36 - English
