Gas Spring
Check the external gas spring (see Figure 8–3) for
sufficient counterbalance force by turning the hand
crank to move the head all the way up and down.
Make sure to first unlock the two dovetail locking
levers. The gas spring counterbalances the entire
upper motor and press assembly up to the maximum
height, which is adjusted by the hand crank. The
rear counterbalance regulator adjusts the pressure
on the internal air cylinder to counterbalance just
the motor. These two items function separately and
should not be confused with each other. If the gas
cylinder has lost pressure, it will not provide suf-
ficient restoring force at its maximum extension,
and should be replaced. The gas spring cannot be
recharged. Contact your local Dukane representa-
tive for the correct part number or you can try and
obtain one directly from Fairchild Fasteners at (818)
998–1412. The upper attachment nut is behind the
name plate as indicated in Figure 8–4 on the next
page. The gas spring may be installed with either the
main cylinder at the bottom or the top. It functions
properly in either orientation.
