TIGHTENING AND RELEASING BOLTS
Put the reaction arm
(13)
onto the spline
(11)
of the wrench. Then put the impact socket
(14)
onto the
square drive
(12)
.
Fix impact socket
(14)
and reaction arm
(13)
with locking pin
(15)
and rubber collar
(16).
Preparation of the torque wrench
Tightening bolts
Set the direction of rotation on the pistol-grip
(1)
at the right / left switch
(5)
above the on / off switch
(4)
.
Put the wrench onto the bolted connection with pre-selected torque (see TORQUE SETTING).
For tightening procedure, move the reaction arm
(13)
to the abutment. For a
loosening
procedure
turn
the reaction arm
(13)
slowly towards the abutment by starting the motor. If necessary start motor at
intervals!
Make sure the reaction arm is tightly fitted against the abutment.
The reaction moment must be absorbed by the reaction arm at the level of the socket.
IMPORTANT NOTE:
The reaction arms will always move for abutment against the direction of
rotation of the wrench.
Keep the on/off switch (4) on the pistol grip (1) pressed down until the selected torque is reached. When
the torque is reached, the motor cuts off automatically. Put the wrench onto the next bolted connection
and tighten the bolt as described above.
Releasing bolts
Select the required direction of rotation, using the reversing switch (5) above the on/off switch (4) on the
pistol grip (1).
If the torque wrench switches off, the torque adjuster setting must be set higher or the higher speed must
be selected.
