6-2. Tool
This is a pistol type hand-held type fastening tool provided with planetary gear, torque transducer,
servomotor, indicator LEDs, and operating switches etc.
①
Starting switch: When the switch is turned ON (by pressing), the tool tip rotates for performing
fastening.
When started in a half-pressed state, the initial speed is maintained even during
free-running.
However, if the initial time is 0 (seconds), this function is cancelled.
When the switch is released during fastening (during rotation of the tip), the fastening
(rotation) is stopped.
However, if the switch is released before switching to the 2nd speed, judgment is not
performed and therefore fastening results will not be generated.
For ordinary fastening operation, continue to grip this switch until fastening is
completed.
②
Reversing switch: This switch is for switching between normal and reverse rotation operations.
When the reverse rotation mode is set, the orange judgment LED flashes rapidly.
When the starting switch is turned ON in this state, the reverse rotation operation is
performed.
When the starting switch is released during the reverse rotation operation, the
operation is stopped.
* The torque limit is caused when you loose the bolt already fastened over 5N
・
m of
default setting in the case of the reverse operation and it automatically stops for safety.
This can be changed in the setting of fastening parameter. See the PAGE6-33,6-62.
If changed, be careful of big torque caused.
