2.1.2 If the loaded indicator is not aligned or the actuator cable is removed,
this indicates that the head may have been actuated (FIGURE 401).
2.1.3 When the operating head is removed from its cylinder, pull the
operating wire. The mechanism of the operating head must act
immediately.
On a Leafield operating head, (FIGURE 401):
(a) The wire loop will separate completely from the operating head.
(b) The gear mechanism on the bottom of the head will rotate.
2.1.4 It is now necessary to service and reset the operating heads.
The procedure used to service operating heads is given in the
manufacturer’s manual listed in the Associated Publications Section
of this manual.
2.1.5 Compare the weight of the cleaned cylinders against the weight
printed on the cylinder label. Cylinders are to be weighed without the
transit cap.
2.1.6 The tolerance for the full weight is +0 g to -56 g. Record the actual
weight on the log card and packing certificate.
A cylinder found to be outside the acceptable tolerance must be
inspected and recharged.
2.1.7 Make sure the syphon tube inside the cylinder is still serviceable.
Shake the cylinder. If the tube is still flexible, it will strike the wall
of the cylinder with a ringing sound. If there is a noticeable delay
before the sound is heard, the tube has stiffened and is no longer
serviceable. You must therefore reject the cylinder.

1, Inf ation System and Gas Charges section).
2.1.9 Find the date of the last hydraulic pressure test. The cylinder will
require a re-test five years after this date.
