Drive Square

To avoid internal damage (especially due to torque overload), the output drive square has been designed to
shear first. This saves major internal damage and allows easy square removal. For drive square part
numbers see page 5.
To replace drive square:
1. Remove the air supply.
2. Support tool in a horizontal position
3. Remove the screw or spring pin, then remove drive square.
If the square has sheared it may be necessary to use pliers to remove the broken parts
4. Fit new drive square.
5. Fit new screw and tighten between 4 N·m to 5 N·m (for PTM52) or 8 N·m to 9 N·m (for PTM72/92/119)
or insert new spring pin.
6. Connect air supply.
TIP: If the drive square fails continually then seek advice from Norbar or a Norbar distributor.
