6.3 Tightening Bracket Bolts
The bottom bracket is held to the aluminium clamp bar by two bolts. If either of these bolts is
loose or slightly tweaked out of shape, the pneumatic seal won’t hold. It is important that these
bolts be tight.
Warning: Bottom Bracket bolts are tapped directly into the aluminium. If they are over-
tightened they may strip out the arm.
1. Check that the bolts on the bottom bracket are tight.
2. If the seal still leaks turn off the air, remove the bolts and apply thread sealant before re-
installing them.
3. Make sure that BOTH bolts are tight. If they are not then the bracket will not sit flush.
6.4 Removing the Cylinder
1. Turn off the air and remove the airline for the
cylinder to be rebuilt. The line is connected to
the cylinder by a push-in fitting. Simply push
the outer ring in as you pull the airline.
2. Loosen the tension screw on the side of the Cylinder Channel.
3. Remove the (4) Wear Strip screws on each side of the Cylinder Channel and remove the
complete cylinder assembly off the arm.
