If necessary, rest the hook on a raised support (e.g. a branch, mound or something similar). : Remove the chain guard. Check that chain is not touching any object or the ground. Check that nobody is standing within the working range of the pruner. : Make sure you have a firm footing. Press the unit firmly against the ground with your left hand on the fan housing. Your thumb should be under the fan housing. Do not stand or kneel on the drive tube. This will bend the tube and result in permanent damage to the telescopic shaft. Alternative method: : Remove the chain guard. Position the shaft on a branch so that it is held by the hook. : Hold the unit firmly with your left hand around the fan housing – your thumb under the fan housing. : Pull the starter grip slowly with your right hand until you feel it engage - and then give it a brisk strong pull. Do not pull out strater rope at full length - it might break. HT 100, HT 101, HT 130, HT 131 English / USA : : : Do not let the starter grip snap back. Guide it slowly back into the housing so that the starter rope can rewind properly. Crank engine until it begins to fire – after no more than five pulls: Set the choke knob to e. Continue cranking. As soon as engine runs: Blip the throttle trigger – the slide control moves to the run position # – and the engine returns to idling speed Make sure carburetor is correctly adjusted – chain must not run when engine is idling. Your pruner is ready for operation. To shut down the engine : Move the slide control in direction of arrow (h) to STOP – $. At very low temperatures As soon as engine runs: : Blip the throttle trigger to disengage the starting throttle position. The slide control moves to the normal run position # and the engine settles down to idle speed. : Open the throttle slightly. : Warm up engine for brief period. If the engine does not start: Choke knob If you did not turn the choke knob to e quickly enough after the engine began to fire, the combustion chamber has flooded. : Choke knob to e : Set slide control, interlock lever and throttle trigger to starting throttle position : Start the engine by pulling the starter rope firmly. 10 to 20 pulls may be necessary. If the engine still does not start: 10 249BA008 KN : Move the slide control to STOP – $. : Pull off the spark plug boot (10). : Unscrew and dry off the spark plug. : Open the throttle wide. : Crank the engine several times with the starter to clear the combustion chamber. : Refit the spark plug. : Connect the spark plug boot (press it down firmly). : Move the slide control to START. : Set the choke knob to e – even if engine is cold. : Now start the engine. HT 100, HT 101, HT 130, HT 131 English / USA Operating Instructions Throttle cable adjustment : Check adjustment of throttle cable – see "Adjusting the Throttle Cable". Tank run until dry : After refueling, press the fuel pump bulb at least five times – even if bulb is filled with fuel. : Set choke knob according to engine temperature. : Now start the engine. During break-in period A factory new machine should not be run at high revs (full throttle off load) for the first three tank fillings. This avoids unnecessary high loads during the break-in period. 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. Do not make the mixture leaner to achieve an apparent increase in power – this could damage the engine – see chapter "Adjusting the Carburetor". During operation Check chain tension frequently! A new chain has to be tensioned more often than one that has been in use for some time. Cold chain 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 chapter "Tensioning the Saw Chain". Chain at operating temperature The chain stretches and begins to sag. The drive links on the underside of the bar must not come out of the bar groove – the chain may otherwise jump off the bar. Retension the chain – see chapter "Tensioning the Saw Chain". Always slacken off the chain again after finishing work. The chain contracts as it cools down. If it is not slackened off, it may damage the crankshaft and bearings. HT 100, HT 101, HT 130, HT 131 English / USA Taking Care of Guide Bar After a long period of full-throttle operation Allow engine to run for a while at idle speed so that the heat in the engine can be dissipated by flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload. After finishing work : Slacken off the chain if you have retensioned it at operating temperature during cutting work. The chain contracts as it cools down. If it is not slackened off, it may damage the crankshaft and bearings. Wait for engine to cool down. Drain the fuel tank. Store the machine in a dry place. Check tightness of nuts and ...
