3-2-2 Pistol Tool
Pistol type hand-held type fastening tool provided with planetary gear, torque transducer, servomotor,
indicator LEDs, and operating switches etc.
①
Starting switch: Starting switch: When the switch is depressed, the tool (output square drive)
rotates for fastening. When the switch is released (during rotation of the tool),
the fastening (rotation) stops. For normal fastening operation, the start switch
must be held until fastening is completed. (Deadman type operation)
②
Reversing switch: Used to switch between normal and reverse rotation direction.
Ring (rotational) type switch
– Rotate ring to switch between normal/reverse
operation (*in older models, this is a pushbutton type switch). When the reverse
rotation mode is selected, the judgment LED flashes orange.
When the start switch is turned ON in this state, the reverse (rotation) operation is
performed until the Start switch is released.
* When loosening a fastener that has already been fastened over 5N
・
m, the default
REVERSE HIGH TORQUE LIMIT setting will stop the reverse operation as a safety
precaution.
This can be changed in the setting of the fastening REVERSE HIGH TORQUE LIMIT
parameter. If changed, be careful of torque reaction caused by higher torque.
③
Judgment / Status LED indicators (4 LEDs):
When the fastening result is OK, the green LED lights up.
In the case of TOTAL OK, the green LED flashes.
When the fastening result is NG (failure), the red LEDs light up.
In the reverse rotation mode and during initialization upon power activation, the
orange LED lights up.
* When using a tool-hanging clamp around the (Torque transducer/planetary gear area)
ensure the correct selection and do not over-torque the clamp or damage can result.
Over tightening, the clamp can cause deformation of the tool case, affecting the rotation
of the tool and/or accuracy of fastening torque.
