j. Operate the thermostat control to the 220 F position and check to
see that the glowlamp is lighted.
The thermostat control has an internal safety stop at 230 F to
prevent overheating the drum and damaging the equipment.
k. Allow 20 minutes for the drier to reach operating temperature.
During this time, the apron travel should be adjusted [(1) below]. When the
drier reaches the temperature preset on the thermostat control (i above),
the glowlamp will go out.
l. Observe the apron travel. If the apron tends to run off to one side
of the feed table and drum, adjust the lateral position of the apron as
(1) Loosen the apron adjustment screw (figure 315).
(2) To cause the apron to track more to the left, move the screw and
feed table extension slightly away from the drier.
(3) To cause the apron to move more to the right, move the screw and
feed table extension slightly toward the drier.
(4) Tighten the apron adjustment screw.
