1.9 Five (5) hydraulic over-center, dead bolt style latches shall be provided on the rear tailgate for holding the door closed.

1.10 Remote grease system for tailgate.

1.11 Flashing arrow board on rear of unit. Controlled in truck cab.

1.12 To prevent overfilling by liquids of the collector body, one (1) 14″ dia. (355.6 mm) stainless steel float ball will be provided.

1.13 A 6″ dia. (152.4 mm) right side body mounted drain will be provided with a knifegate valve to remove water from the front of the collector body. A 6″ x 10′ (152.4 mm x 3.05 m) lay flat drain hose will be provided with cap.

2.0 Vacuum System = 28″ HG
