nylon washers on the screw with the two (2) o-rings
installed (one towards jack end) and three (3) nylon

Detent Screws
(See Figure 3-5.)
OUTRIGGER BEAMS are manufactured with a series of
holes drilled around the CONTACTOR PLATE assembly.
OUTRIGGER SOCKETS are equipped with button head
screws (detent screws) mounted around the CONTAC-
TOR SCREW HEADS on the floor of the outrigger socket.
The detent screws must align with the holes in the outrig-
ger socket before the contactor plate on the outrigger
beam, and the contactor screw heads in the bottom of the
outrigger socket can make contact to complete the inter-
lock circuit.
The purpose of this design is to assure the proper size
outrigger beams are used with their specific AM model to
assure machine stability, i.e. the shorter outrigger beams
of the 20AM, 25AM and 30AM models cannot be mistak-
enly used on higher reaching 36AM or 41AM models.
