SPEED CHANGE HANDWHEEL
- CAUTION -
DO NOT attempt to change spindle RPM unless the motor is running. Dial
speeds will only be approximate. Belt wear will cause a slight variation in
speeds from what is indicated on the dial.
Spindle speeds are adjusted by turning Speed Change Handwheel “P”, Figure 2.14, on the front of
the belt housing. There are two ranges: 60 to 500 and 500 to 4200.
To obtain 60 to 500 (low range):
1. Hold the Hi-Neutral-Lo lever (right rear
side of the attachment) so the gears are
clear of one another.
2. rotate the spindle nose by hand until the
gears line up, then move the Hi-Neu-
tral-Lo lever
to the “Lo” position (back
gear).
3. Use the low range on the drum switch to
engage the back gears.
- CAUTION -
If the back gears do not mesh, do
not force the lever.
To obtain 500 to 4200 (high range):
1. Hold the Hi-Neutral-Lo lever (right rear
side of the attachment) so the gears are
clear of one another.
2. rotate the spindle nose by hand until the
gears line up, then move the Hi-Neu-
tral-Lo lever to the “Hi” position.
3. Set the drum switch to high range.
- CAUTION -
Try to avoid shifting the hi-lo lever when the feed worm is engaged.
