5.2 Frusto-Conical Arrest System TM
(Cinch Strap)
The Frusto-Conical Arrest System (FCAS) allows the pilot
to reduce the volume of the bucket to a preset position.
The FCAS is composed of a cinch strap on the inside or
outside of the bucket. The cinch strap is marked with
one or more load levels. The illustration in Fig. 8 shows a
Bambi Bucket with volume reduced by cinching in the
bucket with the cinch strap. The cinch strap allows you
to reduce the volume of the bucket to lower levels than
can be done by straight fill speed alone.
When the cinch strap is tight, below 100% load
level, the trip line must be lengthened by
moving 3 or 4 links on the adjustment chain.
See Sections 11.1 and 11.3.
The bucket may not dump if the trip line is not properly
adjusted.
It is important to note that with the FCAS the top of the
bucket is always the spill line. The second that the bucket
breaks the surface of the water, it is ready to fly.
IMPORTANT: Varying the speed of the lift is often
the best way to adjust volume. This allows the pilot
to vary the load at each fill to best suit the fuel load
and prevailing lift conditions. Most pilots find it takes
a dozen or so fills to get the feel for the variable fill
action of the Bambi Bucket.
CAUTION: Do not tighten the cinch strap past
the smallest load marking. Overtightening can
damage the bucket shell.
5.3 ADJUSTING THE IDS ADJUSTMENT
CHAIN
An IDS adjustment chain is fitted to older models 2024 -
HL9800. This chain must be adjusted when using the cinch
strap to reduce bucket volume. The chain is lengthened
for lower fill settings (eg. 70%) to allow the IDS to rise
and thereby reduce IDS stresses. This will avoid possible
damage to the IDS. The chain is shortened for higher fill
settings (eg. 90%) to retain the maximum bucket mouth
diameter and hence allow maximum filling efficiency. The
recommended chain adjustments are summarized in Fig.
8.1.
5. FILLING THE BUCKET
Fig. 8: Bambi Bucket cinched in with the FCAS.
CAUTION: The lowest fill setting for all
models is 70%*. Overtightening the cinch strap
could damage the bucket.
