Method of setting torque, Preset type: "EKVTUJOH CBS
1. Holding the grip with your left hand, insert the adjusting tool bar
into the grooves of the adjustment screw and turn to adjust. Turn
clockwise to increase the torque value.
2. Insert with the exclusive bit into the loading device of the Torque
Driver Tester (TDT) and ?x it.
3. Turn the loading device clockwise to measure the torque value. ,QFUHDVH
4. Continue to repeat procedures 1-3 until the torque is matched.

? FTD50-400CN
Method of preloading the FTD
The preload function is a function that uses the handle to apply a *ULS
preloading torque close to that of the measuring point to minimize
the twisting angle during measurement. 6FDOH SODWH
In the FTD series torque screwdrivers, a preload function is 1HHGOH
provided to prevent your wrist from becoming strained and the
torque scale from becoming dif?cult to read when operating close
to the maximum torque.
1. Holding the FTD screwdriver with your left hand, turn the preload 3 -
handle in the counterclockwise direction using the ?ngers of your ' 3 & &
right hand (in case of clockwise measuring).
2. After some slipping turns, the needle will begin to move, and it
will be easy to set an optional torque value.
3. If you do not wish to use the preload function, turn the preload 6HW LQGLFDWRU +DQGOH
handle until there is no tension and the central set indicator (red
mark) points to the FREE mark.

? FTD-S 1HHGOH

Method of setting the FTD-S indicator and memory pointer
1. Make sure the indicator is pointing to zero by matching the scale.
If not, adjust to zero by lightly pushing down on the scale and
rotating it.
2. Turn the memory pointer in the direction opposite to the measuring
direction until it matches the main indicator.
3. Carry out torque measurement or torque tightening. 0HPRU\ SRLQWHU
