Check For String Accumulation
Check for accumulated string and lint on the
drive shaft rollers and bearings.
Perform only when the unit is OFF

Check Rodless Air Cylinder
Bearings
Perform only when the unit is OFF
with power disconnected.
Make sure that the transfer clamp carriage is
moving smoothly along the length of the rodless
air cylinder, without any lateral movement or
play (Figure 4-5).
To ensure proper operation of the transfer
clamp assembly and maximize the life of the
cylinder, the bearings must be replaced at least
every six months. Sooner if needed.
If metal is visible in the cylinder bearings
groove, the bearings will have to be changed more
often. If the groove gets too deep, the cylinder
will have to be replaced.
