Use the regulating handle to set the torque. Turning it clockwise into the casing will increase the torque.
Turning it counterclockwise out of the casing will decrease the torque.
Note: The engraved markings on the engraving ring are for reference only and does not indicate
actual torque output. Torque output can only be determined by repeated testing with a torque meter.
To prevent your torque setting from being tempered, optional torque cover is available which covers
and secures the regulating handle.

Bit insertion: press the slide sleeve into the screwdriver and insert an appropriate bit. When the slide sleeve
is released, the bit will be automatically locked.

Fastening and removing screw
:
To drive a screw, press the “Forward” trigger. To remove a screw, press the “Reverse” lever. If both “Forward”
and “Reverse” levers are pressed at the same time, the screwdriver will not rotate.
Note: Do not change the running direction during operation. Always switch the direction after the
screwdriver has completely stopped.
-
Secure screwdriver during operation: During operation, hang the screwdriver securely (from balancer) in
order to prevent damage to driver and power cord.
-
When the selected torque is reached: The driver features internal clutch assembly. When a screw is
fastened and the selected torque has been reached, the clutch assembly will automatically disengage and
a “click” sound will be heard. At this point, even if the “Forward” trigger is pressed, the power to the motor
will be automatically cut-off.
Note: When driving screws, grasp the driver firmly as recoils generated by the clutch can be
strong.
-
When removing screws: If a previously driven screw cannot be removed using the same torque that it was
driven with, raise the torque setting. When turning the regulating handle, use the number of “click” sounds
as reference so that the torque setting can be changed back afterwards.
-
Operation Frequency: Suggested duty cycle: 0.5s/3.5s (ON/OFF). Total screws: 7000pcs/8hours. To avoid
damage to the screwdriver and to prolong the product life, do not exceed the suggested operational
frequency
