Have such work performed by your STIHL servicing dealer only. Wear gloves when handling or performing maintenance on the cutting attachment. Warning! Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug terminal and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. Warning! Never test the ignition system with the ignition wire boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire. Warning! Do not operate your power tool if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss. If your muffler was equipped with a spark-arresting screen to reduce the risk of fire, never operate your power tool if the screen is missing or damaged. Remember that the risk of forest fires is greater in hot or dry weather. HT 100, HT 101, HT 130, HT 131 English Warning! Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut or burn marks appear on the wood. Keep chain at proper tension. Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use. For maintenance items please also refer to the maintenance chart in this manual. Do not clean your machine with a pressure washer. The solid jet of water may damage parts of the machine. Store the power tool in a dry and high or locked location out of reach of children. Before storing for longer than a few days, always empty the fuel tank. See chapter "Storing the machine" in this manual. Store fuel and chain oil in approved and properly labeled safety-type canisters only. Take care when handling gasoline! Avoid direct contact with the skin and avoid inhaling fuel vapor! Using the Unit Preparations N Wear suitable protective clothing, observe safety precautions. N Adjust telescoping shaft to the required length (HT 101, HT 131 only). N Starting the engine N Put on the shoulder strap. Cutting Sequence To allow branches a free fall, always cut the lower branches first. Prune heavy branches (large diameter) in several controllable pieces. Never stand directly underneath the branch you are cutting – be wary of falling branches. Note that a branch may spring back at you after it hits the ground – risk of injury. Disposal Do not throw cuttings into the garbage can – they can be composted. Working Techniques Hold the control handle with your right hand, and the shaft with your left hand. Your left arm should be extended to the most comfortable position. HT 100, HT 130 Always hold the shaft with your left hand in the area of the handle hose. 390BA018 KN The shaft should always be held at an angle of 60° or less. The least tiring working position is a tool angle of 60°. Any lesser angle may be used to suit the situation concerned. HT 100, HT 101, HT 130, HT 131 HT 100, HT 101, HT 130, HT 131 English 15 Cross-cut To avoid pinching the bar in the cut, position the cutting attachment with the hook against the branch and then perform the cross-cut from the top downwards. Relieving cut To avoid tearing the bark on thick branches, always start by performing a relieving cut (1) on the underside of the branch. N To do this, apply the cutting attachment and pull it across the bottom of the branch in an arc as far as the bar nose. N Perform the cross-cut (2) – position the bar with the hook against the branch and then perform the crosscut. Flush-cutting thick branches If branch diameter is more than 4 in (10 cm), first N perform undercut (3) and then cross-cut at a distance of about 8 in./20 cm (A) from the final cut. Then carry out the flush-cut (4), starting with a relieving cut and finishing with a cross-cut. Cutting above obstacles The unit's long reach makes it possible to prune branches that are overhanging obstacles, such as rivers or lakes. The tool angle in this case depends on the position of the branch. Cutting from a lift bucket The unit's long reach enables cutting to be performed next to the trunk without the risk of the lift bucket damaging other branches. The tool angle in this case depends on the position of the branch. 390BA052 KN 2 1 390BA041 KN 4 3 A 390BA024 KN 390BA058 KN 390BA020 KN English 30° angle drive (special accessory) Fitting the chain Mounting the Bar andChain Removing the chain sprocket cover The angle drive keeps the cutting attachment at an angle of 30° to the drive tube. N Fit the chain – start at the bar nose. The angle drive may be adjusted on the drive tube to the following positions only: 1 For cross-cutting vertical branches and bushes. 2 For a better view of the cutting attachment. 1 2 390BA053 ...
