• Do not force the action mode change knob or do not move it from symbol mode to symbol mode (or vise versa) at once. It may damage the tool. When turning the knob from symbol mode to symbol mode (or vise versa), stop it at symbol mode once. And rotate the chuck clockwise (looking from the chuck side) half turn or until it clicks. Then turn the knob to the desired mode. If it is still difficult to turn the knob, rotate the chuck again. Torque limiter The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning. CAUTION: • As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool. • Bits such as hole saw, which tend to pinch or catch easily in the hole, are not appropriate for this tool. This is because they will cause the torque limiter to actuate too frequently. Hook CAUTION: • Never hook the tool at high location or on potentially unstable surface. 1.
