Speed Chart
The motor is mounted on a plate hinged to the
column. The motor assembly can be released by
turning the handle at the side of the motor. Once
the motor tension is released, the belts can be
easily re-positioned to change speeds.
Examine the speed chart above and the diagram
in
Figure 16
below. The diagram shows one V-
belt connecting the A pulley to the B pulley at the
#3 sheave. The B pulley and C pulley are con-
nected by V-belt at the #1 sheave. Following this
progression along the chart above will show that
the machine is now set to run at 3100 R.P.M.
