2. Worklight (Optional). A switch on the worklight
turns the light "OFF" and "ON". On some machines,
there is a selector switch on the electrical control
box above the Start pushbutton that turns the light
"OFF" and "ON".
3. Controls for the optional DBW-15 Buttwelder are
described in a seperate instruction manual.
BAND SPEED CONTROLS
1. The transmission gear shift lever, band speed
indicator, and variable speed handwheel are located
on the machine's right side below the worktable.
2. The operator can select between "high" and "low"
band speed ranges by moving the transmission
gear shift lever: (a) To the left to obtain "high" range
speeds -- 950 to 5200 fpm (292 to 1584 m/min); (b)
To the right to obtain "low" range speeds -- 55 to
300 fpm (17 to 90 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 handwheel. Turn the
handwheel clockwise to "decrease" the band
speed, counterclockwise to "increase" it. To
determine when the desired speed has been
reached, refer to the band speed indicator while
turning the handwheel.
4. During machine operation, keep the following band
speed and gear shifting precautions in mind:
Adjust the band speed handwheel only while
the machine is running.
Always turn the speed speed handwheel 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.
