WARNING: Do not remove the cover on the
control head while operating the Bambi
Bucket. Part of the trip line safety keeper is
cast into the control head cover. With the
cover removed, this safety feature is no longer
functional. Without the safety keeper
functioning, a separated trip line could cause
a tail rotor strike which could result in severe
injury or death and/or helicopter damage.
NOTE: For proper operation of the control head avoid
the following modifications:
1) Do not use another type of bearing as a replacement
for the ball bearing.
2) Do not use lockwire as a substitute for the swage
blocks on the trip line.
3) Do not shorten or change the portion of the trip line
which attaches to the reel.
4) Do not use threaded bolts as a substitute for clevis
pins.
5) Do not modify the size or angles of the catch, other
than as recommended in Section 13.3.
6) Do not tighten control head suspension bolts over 5
ft-lbs. (6.5 Nm).
13.1 Trip Line Replacement
The trip line should be examined daily for kinks, frays or
loose swages. Replace the trip line as soon as any
deterioration is observed.
CAUTION: Accidental release of a wound
spring reel can result in injury to your hands.
Wear gloves and use caution when winding
the spring reel or pulling the tripline.
Remove Old Tripline
1) If the tripline is not broken above the trip block, and
the spring reel is functional, then push in the solenoid to
activate the linkage and pull the tripline out to its full
extent.
2) Secure the spring reel to prevent the reel from
unwinding. This can be done by clamping a small pair
of vice-grips onto the bottom flange of the reel, locking
the reel against the solenoid. See Fig. 23.
