Belt Platen
DO NOT attempt to operate this machine
before completing the assembly and adjust-
ment instructions. Be sure that the switch is
off and the cord is disconnected from the
power source at all times until assembly
and adjustment are complete and you have
reviewed all safety guidelines. Serious
injury could occur.
The belt platen should be adjusted out far enough
so it is flush with, or slightly higher than the upper
roller. The rollers are slightly crowned, that is they
are higher in the center than at the edges. This
crowning helps the belt to stay centralized on the
rollers. The adjustment of the platen to the roller
should be done at the high point, or center, of the
roller.
1. Loosen the cap screw on the side of the
belt housing with a 6mm Allen
®
wrench.
This frees the in and out movement of the
belt platen
2. Use a straightedge positioned in the center
of the platen which extends over the upper
roller. Adjust the belt platen in and out until
the straightedge is just barely lifted off of
the idler roller.
3. Tighten cap screw.
See the section on Belt Installation/Tracking for
more information on adjusting the rollers for prop-
er tracking.
