7) Kindly note that SKD-RBK60/90/120/180/120F/180F/250 will be enclosed with the torque fixing ring.
The torque fixing ring can protect the operator and avoid getting hurt by the threads on the screwdriver.
And it can fix the torque and prevent the torque to be adjusted.
In order to prevent getting hurt, kindly check if the torque fixing ring is fixed when using the screwdriver
and adjusting the torque.
WARNING
！
DO NOT OPERATE THIS TOOL WITHOUT
PROTECTIVE EARTH CONNECTED
1
、
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 (“

normal if the 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.
