BC Transit – Air Brake Course

Hooking Up (Step 2)
A visual inspection by the operator before backing under the the trailer will
confirm...
1) The trailer height matches that of the fifth wheel
2) The fifth wheel release handle is “open”(jaws are open to accept the king pin.)
3) The trailer is blocked and secure.
Once these steps have
been verified, then it’s
time to connect and
charge the trailer air
system. DO NOT
attempt to back under
the trailer until the air
connections have been
made. Even when
blocked, the jolt may be
enough to move the
trailer over the wheel
blocks and set it rolling.
