As all moving parts have to bed in during the break-in period, the frictional resistances in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings. During Operation Do not make the mixture leaner to achieve an apparent increase in power – this could damage the engine – see "Adjusting the Carburetor". Check chain tension frequently A new chain has to be retensioned more often than one that has been in use for some time. Chain cold Tension is correct when the chain fits snugly against the underside of the bar and can still be pulled along the bar by hand. Retension if necessary – see "Tensioning the Saw Chain". HT 100, HT 101, HT 130, HT 131 English Chain at operating temperature The chain stretches and begins to sag. The drive links must not come out of the bar groove – the chain may otherwise jump off the bar. Retension the chain – see "Tensioning the Saw Chain". The chain contracts as it cools down. If it is not slackened off, it can damage the gear shaft and bearings. After long period of full-throttle operation Allow engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload. After Finishing Work N Slacken off the chain if you have retensioned it at operating temperature during cutting work. Always slacken off the chain after finishing work. The chain contracts as it cools down. If it is not slackened off, it can damage the gear shaft and bearings. Storing your saw for a short period Wait for the engine to cool down. Drain the fuel tank. Store the machine in a dry location. Check the tightness of all accessible screws and nuts (not adjusting screws) at regular intervals and retighten if necessary. Storing for a long period See chapter on "Storing the Machine" Taking Care of the Guide Bar 3 2 1 390BA050 KN N Turn the bar over – every time you sharpen the chain and every time you replace the chain – this helps avoid one-sided wear, especially at the nose and underside of the bar. N Regularly clean the oil inlet hole (1), the oilway (2) and the bar groove (3). N Measure the groove depth – with the scale on the filing gauge (special accessory) – in the area used most for cutting. Chain type Chain pitch Minimum groove depth Picco 3/8" P 0.20" (5.0 mm) Rapid 1/4" 0.16" (4.0 mm) If groove depth is less than specified: N Replace the guide bar. The drive link tangs will otherwise scrape along the bottom of the groove – the cutters and tie straps will not ride on the bar rails. HT 100, HT 101, HT 130, HT 131 English Cleaning the Air Filter Engine Management Adjusting the Carburetor If there is a noticeable loss of engine power 1273BA006 KN24 N Turn the choke knob to g N Take out the screw (1) and remove the filter cover (2). N Clean away loose dirt from around the filter. N Grip the filter element (3) at the cutout (arrow) in the filter housing (4) and remove it. N Fit a new filter element. As a temporary measure you can knock it out on the palm of your hand or blow it out with compressed air. Do not wash. N Replace damaged parts. Installing the filter N Install the filter element in the filter housing and fit the cover. N Insert the screw and tighten it down firmly. Exhaust emissions are controlled by the design of the fundamental engine parameters and components (e.g. carburation, ignition, timing and valve or port timing) without the addition of any major hardware. The carburetor comes from the factory with a standard setting. This setting provides an optimum fuel-air mixture under most operating conditions. With this carburetor it is only possible to adjust the high speed and low speed screws within fine limits. Standard Setting N Stopping the engine N Check chain tension N Check the air filter and clean or replace as necessary. N Check that the throttle cable is properly adjusted – readjust if necessary – see chapter on "Adjusting the Throttle Cable". N Check the spark arresting screen (not in all versions) and clean or replace as necessary. HT 100, HT 101, HT 130, HT 131 English 3/4 H 249BA032 KN LA 3/4 L N Carefully turn both adjusting screws counterclockwise as far as stop: – The high speed screw (H) is 3/4 turn open. – The low speed screw (L) is 3/4 turn open. N Start and warm up the engine. N Adjust idle speed with the idle speed screw (LA) so that the chain does not run. Fine Tuning A slight correction of the setting of the high speed screw (H) may be necessary if engine power is not satisfactory when operating at high altitude or at sea level. Rule of thumb: Turn the high speed screw (H) about one quarter of a turn for every 1000 m (3300 ft) change in altitude. Conditions for adjustment N Carry out the standard setting without disturbing the high speed screw (H). N Warm up the engine for about 3 minutes. N Open the throttle wide. At high altitude N Turn the high speed screw (H) clockwise (leaner), no furthe...
