Risk of components damage due to incorrect disassembly.
During disassembly the end caps can be damaged due to un-
even force generated by compressed springs.
Î
Remove the end caps as shown in Fig. 9-4 keeping a
constant distance (A = B) between the actuator body and
the end cap interface.
Î
Observe the speci
fi
ed sequence shown in Fig. 9-5.

−
Release the springs compression by partially unscrewing
each end cap bolt (13) 1 turn at a time as per the sequen-
ce shown in Fig. 9-5 for the number of turns indicated in
Table 9-2.
Risk of personal injury due to compressed springs.
End caps are under tension when the springs are compressed.
Î
If there is still force on the end cap (30/30R) after
uscrewing the cap screws (13) for the number of turns in-
dicated in Table 9-3, the spring cartridge may have been
damaged or the pistons are not completely closed: stop
the disassembly and contact AIR TORQUE.
