Stihl HT 105 Instruction Manual - Page 10

English WARNING Proper chain tension is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hex nut(s) for the sprocket cover is (are) tightened securely after tensioning the chain. Check chain tension once more after having tightened the nut(s). Never start the pole pruner with the sprocket cover loose. Adjust carrying harness and hand grip to suit your size before starting work. For specific starting instructions, see the appropriate section of your instruction manual. Starting To reduce the risk of serious personal injury from fire, start the engine at least 10 feet (3 m) from the fueling spot, outdoors only. Start and operate your pole pruner without assistance. Your power tool is a one-person machine. Do not allow other persons in the general work area, even when starting. For specific starting instructions, see the appropriate section of your manual. Place the pole pruner on firm ground or other solid surface in an open area or, in the alternative, as shown in the above picture. Maintain good balance and secure footing. WARNING To reduce the risk of injury from loss of control, do not attempt to "drop start" your power tool. Drop starting means pushing the machine away from the operator, or allowing it to drop toward the ground, while pulling on the starter grip. This method is very dangerous because you may lose control of the machine. WARNING To reduce the risk of injury from loss of control be absolutely sure that the guide bar and chain are clear of you and all other obstructions and objects, including the ground, because when the engine starts at starting-throttle, engine speed will be fast enough for the clutch to engage the sprocket and turn the chain. Once the engine has started, immediately blip the throttle trigger, which should release the starting throttle and allow the engine to slow down to idle. 275BA006 KN With the engine running only at idle, attach the power tool to the spring hook of your harness (see appropriate chapter of this manual). WARNING When you pull the starter grip, do not wrap the starter rope around your hand. Do not let the grip snap back, but guide the starter rope to permit the rope to rewind properly. Failure to follow this procedure may result in injury to your hand or fingers and may damage the starter mechanism. Important Adjustments WARNING To reduce the risk of personal injury from loss of control or contact with the running cutting tool, do not use your unit with incorrect idle adjustment. At correct idle speed, the saw chain should not move. For directions on how to adjust idle speed, see the appropriate section of your instruction manual. If you cannot set the correct idle speed, have your STIHL dealer check your power tool and make proper adjustments and repairs. Proper chain tension is very important at all times. Check it at regular intervals (during work breaks and only when the pole pruner is shut off). If the chain becomes loose while cutting, switch off the engine and then tighten. Never try to tighten the chain while the engine is running. 8 HT 105, HT 134, HT 135
