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 pintch 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. 5
