This tool should be grounded while in use to protect the operator from electric shock. NOTICE! To ensure the
grounding result, the grounding conductor of the power cord must be well connected with the grounding terminal
of power facility. This tool is equipped with grounding conductors. The Green (or Green and Yellow)conductor in
the Power Cord is the grounding wire. Never connect Green (or Green and Yellow) to a live terminal. The
grounding wires in this tool can not only earth the electric leakage safely, but also can eliminate ESD-the
electrostatic that tool occurred while in use.

The grounding is the most important task a user. Periodically, depends on the working condition and
circumstance, for maintaining a good function the user has to check the grounding condition every 3~6 months
by an electric meter and following simple steps; Set the Ohm meter to level R*100(Ohm). Touching 2 test rods

meter is read as close as to “0”. For getting a normal indication on the meter while in testing, need to press the
test rods firmly to the testing objects.

The instrument QC of the tool is performed before the tool ex-factory. The grounding continuity test is conducted
by input 26A voltage to the end of earth terminal, and subject to the resistance value lower than 0.3Ohm.
1) Whenever changing a bit, make certain the Forward / Reverse Switch is in the “OFF “position and tool is
unplugged.
2) Do not allow chemicals such as acetone, benzene, thinner, trichloroethylene ketone, or other similar chemicals
to come in contact with the screwdriver housing as damage will result.
3) Do not drop or abuse the screwdriver.
4) Do not adjust the torque setting higher than 8 on the torque scale.
5) There should be a tool rest interval when cycles three seconds or longer. This tool is intended for a duty cycle of
1.0 sec on, 3.0 sec off.
6) Do not use this screwdriver for tightening wood screws. This is “Metal Assembly Screw Driver”
7) Do not operate the Forward / Reverse Switch the motor is running.
8) Whenever a tool is not being used, move the Forward / Reverse Switch to the “OFF” position and unplug the
screwdriver.
9) Don't touch For&Rev Switch during operating for keeping system from wrong judgment.
10)
Use cable for the external counter and I/O box is shield cable for avoidance of electrical interference
Use Anti-interference lines.
