Section 2: Deploying the Bambi Bucket
Deployment Instructions
Control Head Operation
Warning
Do not remove the cover on the control head while operating the Bambi bucket. Part of the tripline
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 tripline could cause a tail
rotor strike which could result in severe injury or death and/or helicopter damage.
For proper operation of the control head, avoid the following modifications:
• Do not use another type of bearing as a replacement for the ball bearing.
• Do not use lockwire as a substitute for the swage blocks on the tripline.
• Do not shorten or change the portion of the tripline which attaches to the reel.
• Do not use threaded bolts as a substitute for clevis pins.
• Do not modify the size or angles of the catch, other than as recommended.
• Do not tighten control head suspension bolts over 5 ft.-lbs. (6.5 Nm).
Connecting Power
Important Note
To operate the solenoid and release the water, use a momentary contact switch rated for 5 amps
at 24 VDC. A suitable switch is available from SEI Industries. Alternatively, a lower rated switch
may be used with a relay (see suggested wiring diagram). The solenoid has a 10% duty cycle
(designed to not be operated more than 10% of the time). Operating the solenoid continuously will
result in solenoid failure.
The control head of the Bambi bucket comes equipped with a short length of electrical cable. A popular
wiring hookup involves fitting a common electrical plug to the end of the cable or whatever matches the
plug installed on your aircraft.
