BAND SPEED CONTROLS
1. The transmission gear shift lever is located on the
machine's right side under the worktable, the band
speed knob is located on the pushbutton control
box on the front of the machine.
2. The operator can select between "high" and "low"
band speed ranges by sliding and hold down the
shift lock knob and then moving 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. Band speed within both ranges is changed by
turning the Band Speed adjustment knob on the
pushbutton control box clockwise to increase 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 band speed knob to the lowest
speed within its range before stopping the
machine.
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.
DO NOT attempt to force the gear shift lever
into place.
