At start-up, a small amount of
current is allowed.

As the load increases during
fastening, so does the amountof current allowed.

When the desired current value(adjusted by corresponding torquevalue) is reached, current flow is
cut off and the screwdriver stops.

Two types of fastening mode available subject to the workpiece and fastening conditions. Coordinate the actual workpieces,screws and operating conditions and determine the fastening mode, torque range and rotation speed.

SOFT / HARD fastening Settings

Instruction manual P68, P69

SOFT fastening setting

HARD fastening setting

Suitable for workpieces with high fastening load such as
tapping screws or fastening soft objects such as rubber.

Suitable for workpieces with small fastening load such as
threaded holes or rigid bodies such as metal.

Instruction manual P43

A torque value that alerts the operator canbe set. After the channel is switched, if thetorque exceeds the preset value, a warning
is displayed on the counter and the electricscrewdriver will not start.

2. Refastening prohibited time setting

To prevent additional fastening (second tightening, confirmationtightening, etc.), it can be set so that it does not restart after torque-up(for 0.0 to 9.9 seconds).
Adjust the set value according to the skill
level of the operator and the interval
between screw fastening operations.
