3.2.2.1 Look through the large inspection opening in the side of the
machine and move any one bogie until the forward four of its
six yellow guide wheels are just out of the curve coming down
on the opposite side of the drive drum, and onto the start of the
bottom straight rail section. The bogies may be moved using
the control unit, set to a low speed (6 - 10 Hz), or by hand. To
avoid injury when moving it by hand, only handle it by the
round axles of the link sections.
3.2.2.2 Evenly lower the machine frame until the two black rubber
stoppers at the end of the trailing arms that hold the rubber
wheel just start to move away from the metal plate underneath
it. (See fig 3)
3.2.2.3 DISCONNECT THE MOTOR CONTROL UNIT FROM THE
MAINS. Refer to fig. 5, p16 and find the PVC measuring tool,
shaped like a human leg and foot. The “toe” of the gauge is
8mm high, increasing to 10mm where it is attached to the “leg”.
Holding the gauge by the “leg”, measure the gap underneath the
rubber stopper. Only one of the two stoppers needs to be
checked. Lowering the machine will increase the gap and
vice
versa
. The setting is correct when the “foot” fits in the gap
with little or no clearance. A tolerance of one or two mm to
either side is allowable.
3.2.2.4 Move the bogie forward until the forward two of its six yellow
guide wheels are just at the end of the bottom straight rail
section. ALWAYS DISCONNECT THE MAINS SUPPLY
BEFORE WORKING INSIDE THE MACHINE. Check that
the gap is still about the same. If not, adjust the two feet at that
end of the frame to correct it, even if it means that the machine
is not standing horizontal in the length-wise direction. Recheck
the gap in the first position.
3.2.2.5 Lock the four legs to prevent further rotation.
