• Always switch off the tool before installing or removing of the battery cartridge.

• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury. To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge. To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely. CAUTION:

• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly. Tool / battery protection system The tool is equipped with a tool/battery protection system. This system automatically cuts off the power to extend tool and battery life. The tool will automatically stop during operation if the tool or battery is placed under one of the following conditions: Overload protection This protection works when the tool is operated in a manner that causes it to draw an abnormally high current. In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart. Overheat protection This protection works when the tool or battery is overheated. In this situation, let the tool and battery cool before turning the tool on again. Overdischarge protection This protection works when the remaining battery capacity gets low. In this situation, remove the battery from the tool and charge the battery. Indicating the remaining battery capacity Only for battery cartridges with the indicator Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds. (Fig. 2) Indicator lamps Remaining capacity Lighted Off Blinking 75% to 100% 50% to 75% 25% to 50% 0% to 25% Charge the battery. The battery may have malfunctioned.10 NOTE:

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

• The first (far left) indicator lamp will blink when the battery protection system works. Switch action CAUTION:

• Before inserting the battery cartridge into the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released. (Fig. 3) For your safety, this tool is equipped with a dual switching system. To turn on the tool, press the lock-off button and triggers A and B. Release either one of the two pressed triggers to turn off. The sequence of switching is unimportant as the tool only starts when both switches are activated. Indication lamp (Fig. 4) Running the tool allows the indication lamp to show the battery cartridge capacity status. When the tool is also overloaded and has stopped during operation, the lamp lights up in red. Refer to the following table for the status and action to be taken for the indication lamp. Note 1: The time at which the indication lamp lights up varies by the temperature around the work area and the battery cartridge conditions.

• Be careful not to accidentally contact a metal fence or other hard objects while trimming. The blade will break and may cause serious injury.

• Overreaching with a hedge trimmer, particularly from a ladder, is extremely dangerous. Do not work from anything wobbly or infirm. NOTICE: Do not attempt to cut branches thicker than 10 mm in diameter with the tool. Cut branches to 10 cm lower than the cutting height using branch cutters before using the tool. (Fig. 5) CAUTION:

• Do not cut off dead trees or similar hard objects. Failure to do so may damage the tool. (Fig. 6) Hold the trimmer with both hands and pull the switch trigger A or B and then move it in front of your body. (Fig. 7) As a basic operation, tilt the blades towards the trimming direction and move it calmly and slowly at the speed rate of 3 - 4 seconds per meter. (Fig. 8) To cut a hedge top evenly, it helps to tie a string at the desired hedge height and to trim along it, using it as a reference line. (Fig. 9) Attaching the chip receiver (optional accessory) on the tool when trimming the hedge straight can avoid cut off leaves’ being thrown away. (Fig. 10) To cut a hedge side evenly, it helps to cut from the bottom upwards. (Fig. 11) Trim boxwood or rhododendron from the base toward the top for a nice appearance and good job. Installing or removing chip receiver (optional accessory) CAUTION:

• Always be sure that the tool is switched off and unplugged before installing or removing chip receiver. NOTE:

• When replacing the chip receiver, always wear gloves so that hands and face does not directly contact the blade. Failure to do so may cause personal injury.

• Always be sure to remove the blade cover before installing the chip receiver.

• The chip receiver receives cut-off leaves and alleviates collecting thrown-away leaves. This can be installed on either side of the tool. (Fig. 12) Press the chip receiver on the shear blades so that its slits overlap with the nuts on the shear blades. (Fig. 13) At this time, the chip receiver needs to be installed so that its hooks fit into grooves in the shear blade unit. (Fig. 14) To remove the chip receiver, press its lever on both sides so that the hooks are unlocked. CAUTION:
