there is a selector switch on the electrical control
box above the Band Start pushbutton that turns
the light "OFF" and "ON".

BAND SPEED CONTROLS
1. The transmission gear shift lever is located on the
machine's right side below the worktable. The band
speed control is located on the electrical control
box.
2. The operator can select between "high" and "low"
band speed ranges by hold down the shift lever
lock and move the transmission gear shift lever:
(a) To the left to obtain "high" range speeds -- 550
to 5500 fpm (170 to 1675 m/min); (b) To the right
to obtain "low" range speeds -- 30 to 320 fpm (10
to 100 m/min).
• The "neutral" position is in the middle of the slot.
The band speed MUST be at its lowest speed before
the shift lever can be moved to "neutral".
3. Variable speed within both ranges is changed
by turning the Band Speed knob. Turn the
control clockwise to "increase" the band speed,
counterclockwise to "decrease" it.
4. During machine operation, keep the following band
speed and gear shifting precautions in mind:
Adjust the band speed only while the machine
is running.
Always turn the speed speed to its lowest
speed before stopping the machine or shifting
into "neutral".
Always allow the saw band to stop completely
before opening any bandwheel door.
Stop the machine to shift gears. Then turn
the drive bandwheel by hand to engage the
clutch while shifting.
5. If the transmission gears are not in position to
mesh: (a) Turn the machine off; (b) Open the lower
bandwheel door, and; (c) Manually turn the lower
bandwheel until meshing occurs. DO NOT attempt
to force the gear shift lever into place.
