Section 1: Sacksafoam Overview
Introduction
This manual provides helicopter operators with important information on the operation and maintenance of
the Sacksafoam I dispensing system for use with the Bambi bucket.
Please read this manual prior to flying the bucket, particularly the sections on installation, filling and dis-
pensing. If problems are experienced, please refer to the manual. Section 6 Troubleshooting may be espe-
cially helpful.
For your own protection and for longer system life, always heed the instructions and warnings. Ignoring
them could result in damage to the Sacksafoam I, Bambi bucket, aircraft or personal injury.
The Sacksafoam I has a number of advanced features to enhance the efficiency of helicopter fire fighting:
• The sack containing the foam concentrate mounts in the Bambi bucket. This eliminates
spillage and possible corrosion damage associated with carrying foam concentrate
inside the helicopter. An internal check valve stops water from flowing into the sack
and insures that foam is dispensed only while the injection pump is operating. Because
the foam in the sack displaces the water in the Bambi bucket, the total payload is always
constant.
• An optional foam transfer pump for easily filling the Sacksafoam I is available from
SEI Industries. This portable pump greatly facilitates the filling of the Sacksafoam I
and is powered by 24 volts DC, either from the aircraft or from an auxiliary power
source.
• The operation of the Sacksafoam I can be quickly mastered by users with no prior expe-
rience. Several dumps with foam will provide familiarity with the use of the system.
SEI offers complete parts supply and repair facilities for the Sacksafoam I. For maintenance and repair pur-
poses, parts diagrams and descriptions are provided in Section 9 Parts. When ordering parts, please provide
the model information which is silk-screened on the bladder.
Additional copies of this manual are also available from SEI Industries Ltd. or by visiting our website at
www.bambibucket.com for more information on these products. An online version of this manual is also
available at this website.

Installation Procedure
To install the sack:
1. Release the bottom end of the ballast side IDS
restrainer cable by removing the clevis pin from
the restrainer bracket inside the bucket.
2. Tie the restrainer cable out of the way where it
will not interfere with bucket operation. It may
be reused to restrain the IDS hub if the sack and
IDS restrainer strap are later removed.
Important Note
If the Bambi bucket cinch strap hook is on the ballast side of the bucket, it must be rotated 180
degrees to the opposite side, to allow cinch adjustment once the sack is installed.

3. Attach one end of the chain to the 1/4" shackle
and attach the shackle to the IDS hub. Determine
the length of chain from the table. Insert the
quick link into the determined chain length and
insert the quick link into the D-ring at the end of
the webbing strap and secure.

4. Connect the lower end of the restrainer strap to the restrainer bracket, reinstalling the clevis pin
(removed in step 1). Use a new cotter pin to secure the clevis pin to the restrainer bracket.
5. Disconnect the bottom end of the IDS
restrainer cable, opposite the ballast, by
removing the clevis pin from the restrainer
bracket. Attach the supplied shackle and
length of chain to the IDS restrainer cable and
re-connect it to the bracket. If the IDS cable
already has a chain fitted, extend it to its long-
est length.
The installation should now look like this.
