Tightening Bracket Bolts
The bottom bracket is held to the aluminum clamp bar by two bolts. If either of these bolts are loose
or slightly tweaked out of shape, the pneumatic seal won’t hold. It is important that these bolts be
tight, but they are tapped directly into the aluminum so if they are over-tightened they will strip the
arm out.
SOLUTION STEPS:
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.
