• An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary. Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor. Lubricating the bar tip sprocket Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. Needle bearing lubrication The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. See instructions under the heading Cutting equipment. Adjustment of the oil pump The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti- clockwise will increase the oil flow. –+ 12 3 Recommended settings: Bar 13"-15": Position 1 Bar 15"-18": Position 2 Bar 18"-20": Position 3 ! WARNING! The engine must be stopped when making adjustments. English – 35 MAINTENANCE 36 – English Cooling system To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel. 4 Cooling fins on the cylinder. 5 Cylinder cover (directs cold air over the cylinder). 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. 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. 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: • Partly mask the air inlet on the starter to increase the working temperature of the engine. • Preheat the intake air to the carburetor by using the heat from the cylinder. Temperature 0°C (32°F) or colder: The cylinder cover is designed so it can be adjusted for running in cold weather. Twist the winter flap so that preheated air from the cylinder can pass into the carburetor space preventing icing of the air filter, etc. For temperatures below -5°C (23°F) and/or in snow conditions there is also: • a special cover (A) for the starter housing • a winter plug (B) for the air nozzle that is fitted as shown. These reduce the flow of cooling air and prevent large amounts of snow from being sucked into the carburetor space. CAUTION! When the winter plug is fitted the winter flap must be open! 1 2 5 4 3 IMPORTANT! If the temperature rises above -5°C (23°F) or 0°C (32°F) respectively the machine MUST be restored to its normal set-up. Otherwise there is a risk of overheating, which can cause severe engine damage. H H MAINTENANCE Heated handles (CS 2152W, CS 2153W) On models with the model code W, both the front handle bar and the rear handle are equipped with electrical heating coils. These are supplied with electricity from a generator built into the chain saw. When the switch is pushed downwards, the heat is switched on. When the switch is pushed upwards, the heat is switched off. Electrical carburetor heating (CS 2152WH, CS 2153WH) On models with the designation CARBURETOR HEATING there is an electrically heated carburetor. Electrically powered heating prevents ice formation in the carburetor. A thermostat regulates the heating so that the carburetor always has the right working temperature.
