Fastening and removing screw
:
To drive a screw, set the forward/reverse switch to FWD position. To remove a screw, set the switch to REV
position. Press the trigger to operate.
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. The LED indicator on the driver will also turn on. 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. Do not go
over the suggested operational frequency in order to avoid damage to the screwdriver and prolong the
product life.
-
Overloading Operation: If the operator discovered the handle overheating or the revolutions plunging
rapidly while fastening, it means that the screwdriver is overloaded. Please change to a torque
screwdriver with higher power or reduce the frequency of fastening to prolong the lifespan of the
screwdriver.
-
If the screwdriver operated for a long period, or if excessive current surges are experienced, the
screwdriver may overheat. In this case it will switch off automatically. When the heat has dispersed,
normal operation can be resumed.
