Do not pull the recoil starter to the end of the rope travel. Pulling the recoil starter to the end of the rope travel can damage the starter. Open When the Engine Starts... WARNING! The cutting blades may move when the engine is started. Keep away from the cutter assembly while starting the engine. IMPORTANT! If the engine fails to start after several attempts with the choke in the closed position, the engine may be flooded with fuel. If flooding is suspected, move the choke lever to the open position and repeatedly pull the recoil starter to remove excess fuel and start the engine. If the engine still fails to start, refer to the troubleshooting section of this manual. WARNING! Never start the engine from the operating position. ¦ After the engine starts, allow the engine to warm up at idle 2 or 3 minutes before operating the unit. 2.

The cutter attachment must never rotate at engine idle speed. If the idle speed cannot be adjusted by the procedures described here, return the pruner to your Shindaiwa dealer for inspection. NOTE: The mixture of the carburetor on this unit cannot be adjusted. The engine must return to idle speed whenever the throttle trigger is released. Idle speed is adjustable and must be set low enough to permit the engine clutch to disengage the cutter attachment when throttle trigger is released. Check and Adjust Idle Speed 1. Start the engine and allow it to idle two or three minutes, or until it warms up. 2. If the cutter attachment rotates at engine idle, reduce idle speed by turning the idle adjusting screw counterclockwise as necessary. 3. If the engine is stalling and won’t idle, increase idle speed by turning the idle adjustment screw clockwise. IMPORTANT! Use a tachometer, if one is available, to set engine idle. Standard idle speed is: 2,750 (±250) min-1. Idle Adjusting Screw Using the Pole Pruner This machine is designed especially for cutting branches. Never use this machine for any other purpose. Never try to cut stones, metals, plastics, or any other hard objects. Using for purposes other than cutting branches may damage the machine or cause serious injury. Preparations ¦ Wear suitable protective clothing and equipment – see section “Safety Precautions”. ¦ Choose the best work position for safety against falling objects such as branches. ¦ Start the engine. ¦ Put on the strap. Never stand directly underneath the branch you are cutting – be aware of falling branches. Note that a branch may spring back at you after it hits the ground. Cutting Sequence: To allow branches to fall freely, always cut the bottom branches first. Prune heavy branches (large in diameter) in several controllable pieces. Working Position: 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. The shaft should always be held at an angle of 60° or less. Standard Cut: The most convenient working position is a tool angle of 60°, but any other angle may be used to suit the situation. Cutting Above Obstacles: Thanks to the unit’s long reach it is 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 On A Work Platform: The unit’s long reach enables cutting to be performed next to the trunk without the risk of the work platform damaging other branches. Tool angle in this case depends on the position of the branch. Relieving Cut: To avoid tearing the bark, kickback or pinching the bar when pruning thick branches, always start by performing a relieving cut (1) on the underside of the branch. To do this, apply the cutting attachment a...
