Installation
1) Mount the arm in the pivot of the angle mount.
2) Adjust the counterbalance of the arm to eliminate the possibility of the arm striking the
operator when positioned at its lowest point.
3) Connect the machine to a grounded 110 volt, 1 phase electric supply.
CAUTION: When making repairs to this unit, always disconnect the main power supply.
4) Flip the forward switch on the hydraulic motor of the tapping head. The rotation of the
hydraulic motor is correct if the tapping head rotates clockwise. If it turns
counterclockwise or does not rotate, reserve the two phases at the supply connection,
not in the internal electric panel.
5) Always wear safety glasses and use proper safety precautions when operating this unit.
Gloves are not recommended when operating this machine.
ALWAYS SECURE THE WORK PIECE TO THE TABLE BEFORE OPERATING.
This machine is designed for tapping, chamfering and light reaming of holes up to M18 diameter.
FlexArm Inc is not responsible for accident or injury resulting from the misuse of this machine.

Use of tap lubricator system
FlexArm mounts a standard tap lubricator system in its tapping units. [Refer to diagram]
•Connect air inlet and arm pneumatic tube to the regulator-manometer which is adjusted in our factory.
•Fill oil tank located in front lower arm: uncover the filler plug and fill with tapping oil to the maximum level.
•Press and hold the starting lever until you see atomized oil begin to leave for the lance tip. The first time, the
atomized oil will take time to reach the lance tip, but later uses will be much quicker.
•Adjust the quantity of oil mixture released by adjusting the oil regulator mounted behind lance.
•The tap lubricator system can be used before, during and after tapping pieces.

Use of the multi-position head
FlexArm models GH-18 that are equipped with a multi-position head.
The multi-positional head allows taping in additional positions. This kind of
tapping doesn't guarantee the perfect thread but will provide a good tapping
quality.
PRESS RED
LEVER
•Loosen the large lever to adjust the position of the tapping head
between vertical and horizontal tapping. Loosen the small lever to adjust
the head position from right to left.
•Before Tapping, check the small lever isn't fixed, since it must be loose for
tapping.
•When returning the head to the vertical tapping position, remember that
both levers must be secure to tap.
