bits.
5) Connect the plug to the socket. Attention : It will cause an electric shock if the plug or the hand is wet.
6) You can adjust the torque by the torque adjusting ring. The number on the scale is not equal to the real torque, please refer to our
torque range chart, or test the torque by our torque meter.
Attention : Hi gear Do not adjust the torque setting higher than 8 on the torque scale.
Lo gear Do not adjust the torque setting higher than 4 on the torque scale.
7) Operation frequency: The original setting of the frequency is 1 sec on / 3 sec off. The number of screw fastened is
about 15 pcs. Over frequently using makes the motor overheated and damage to screwdriver.
Enough heat-dissipation is good for screwdriver.
8) Do not use this screwdriver for tightening wood screws. This is “ Metal Assembly Screwdriver ”
9) Do not operate the Forward / Reverse Switch the motor is running.
10) Whenever a tool is not being used, move the Forward / Reverse Switch to the “OFF” position and unplug the screwdriver.
11) Don't touch For&Rew Switch during operating for keeping system from wrong judgement.
12) Use cable for the external counter and I/O box is shield cable for avoidance of electrical interference Use Anti-interference lines.
13) Keep staying aware.
Pay attention on your work, check safety measures and every part is workable before using screwdrivers, to
make sure screwdrivers can work under original design function.

Operations Cautions
Slow speed Duty Cycle Conversion (for reference)
Based on 1000 rpm, 1 second ON/3 seconds OFF. For example, the duty cycle for 350rpm,1000-350=650
，
650/1000%=65%
ON= 1*1.65= 1.65
，
OFF =3*1.65 =4.95 (rounded value) =2 seconds ON / 5 seconds OFF
This tool is intended for a duty cycle of 2.0 sec on, 5.0 sec off.
