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 further than stop, until there is no noticeable increase in engine speed. At sea level N Turn the high speed screw (H) counterclockwise (richer), no further than stop, until there is no noticeable increase in engine speed. It is possible that maximum engine speed may be reached with the standard setting. Adjusting Idle Speed It is usually necessary to change the setting of the idle speed screw (LA) after every correction to the low speed screw (L). N Warm up the engine for about 3 minutes. Engine stops while idling N Turn the idle speed screw (LA) slowly clockwise until the engine runs smoothly – the chain must not rotate. Chain rotates when engine is idling N Turn the idle speed screw (LA) counterclockwise until the chain stops rotating and then turn the screw about another 1/2 to 3/4 turn in the same direction. If the chain continues moving when the engine is idling, have your saw machine and repaired by your servicing dealer. Erratic idling behavior, engine stops even though setting of LA-screw has been corrected, poor acceleration Idle setting is too lean N Turn the low speed screw (L) counterclockwise, no further than stop, until the engine runs and accelerates smoothly. Erratic idling behavior Idle setting is too rich N Turn the low speed screw (L) clockwise, no further than stop, until the engine runs and accelerates smoothly. HT 100, HT 101, HT 130, HT 131 Spark Arresting Screen inMuffler If the engine is down on power, check the spark arresting screen in the muffler. N Wait for the muffler to cool down. N Move the slide control to STOP-0. NTake out the screw (1). NTake out the screws (2) and remove the shroud (3). NTake out the screw (4). 249BA059 KN 1232249BA060 KN N Lift the spark arresting screen (5) and pull it out. N Clean the spark arresting screen. If the screen is damaged or heavily ca...
