Operating instructions
Make sure the power is switched off to install or replace
screwdriver bits; press the front-end iron cap will allow the
screwdriver bits to be inserted or released.
It is recommended to suspend the electric screwdriver by a
flexible balancer for easy operation and prevent its dropping.
Adjust the torque dial to the proper position according to the
dial/torque table for each model.
The forward/reverse switch should be set to the forward
position when fastening screws. Press the start switch to
complete the operation. The automatic control model will shut
off the power and stop the rotation of the screwdriver bit as
soon as the set torque value is reached.
Position the forward/reverse switch to reverse to loosen screws.
Use hands to hold the electric screwdriver during operation.
Keep it in a perpendicular position with the screw and apply
pressure slightly to prevent slipping.
Use hands or other means to fix the object operated and operate
the electrical power screwdriver safely.
Do not switch the forward/reverse position and improper
switch operations when the motor is running to prevent the
short-circuit of the start switch.
Use it under the normal operation frequency (8 working hours
per day and fasten 800-1000 screws per hour) without
exceeding the operation load will extend the life time of the
electric screwdriver and reduce the occurrences of malfunction.
Please do not use this type of electric screwdriver to fasten
wooden screws.
Regular simple maintenance
