SEI. For maintenance and repair purposes, parts diagrams and descriptions are provided in this manual. When you are ordering parts, please provide the model and serial number of your Bambi MAX as shown on the data tags located inside the bucket shell.
Description The Bambi MAX uses a tubular type valve with seals located on the top and bottom of the tube. When in the default closed position, the seals make contact with top plate and bottom ring of the valve assembly.
Page 8
When the operator releases the push button, the open signal is removed. The motor rotates counter- clockwise and closes the valve. When the closed sensor is triggered by the cam, the motor turns off and the tube remains in the closed position. Bambi MAX Service Manual – Models HL4000-HL9800...
Page 9
The information in this manual may only be applicable to products received after the most recent release date of this manual. CAUTION The control enclosure is hermetically sealed. Unauthorized opening will void the warranty. Bambi MAX Service Manual – Models HL4000-HL9800...
CAUTION The Bambi MAX Bucket may not be suitable for a direct hook-up to the cargo hook. The actual hook- up will be different for various aircraft and operators must comply with all instructions and bulletins supplied by the aircraft manufacturer.
Changing the connector(s) may void the warranty. The purpose of this type of plug is to offer a clean breakaway if the Bambi MAX must be jettisoned from the aircraft in an emergency. It is suggested that the plug be lightly taped together with vinyl tape, while in use, to ensure that wind action does not separate the plug during flight.
It is important to remember that when conduit is duct taped to the outside of a longline, the flight characteristics can change. In our experience, it may take some time and a few trial flights to determine the length between attachment points of the conduit to the longline. Bambi MAX Service Manual – Models HL4000-HL9800...
Checking Tail Rotor Clearance WARNING Using a Bambi bucket with insufficient tail rotor clearance could result in a tail rotor strike which could result in serious injury or death. When a Bambi MAX Bucket is attached directly to the helicopter cargo hook or attached using a longline less than 50 ft (15 m) in length, it is important to confirm that there is adequate tail rotor clearance.
The instant deployment system uses a hub and spoke mechanism to automatically expand the mouth of the bucket as soon as the weight of the Bambi MAX is taken up by the suspension cables. When the bucket is full, the IDS deployment cable and hub restrainer cables should be slack as they should not bear any load.

28 VDC BBXHL5000 Foam Compatibility The Bambi MAX is designed to be effective with foam. All materials used in the manufacture of the Bambi MAX are resistant to the chemical action of foam. NOTICE After using foam or retardants, cycle through several dumps with water only or hose down with fresh water to prolong the bucket life.
Section 3: Accessories Power Pack The Bambi Power Pack is a 28.8VDC, rechargeable power supply that allows the Bambi Bucket or Bambi MAX to be operated independently of the aircraft power. The plastic case contains a NiMH battery pack and battery charger.
