2. Turn on the conveyor belt.
3. Adjust tracking using the same adjustment
screws that were used for tensioning in
Figure 13.
4. If the conveyor belt is moving to the right
side, turn the right screw clockwise. This will
return the tracking toward the left.
5. If the conveyor belt is moving to the left
side, turn the left screw clockwise. This will
return the tracking toward the right.
6. A positioning wheel (Figure 14) has been
provided on the right and left sides of the
conveyor belt to limit the belt tracking. When
adjusting the tracking, the conveyor belt
should be moved until its edge just touches
the positioning wheels.
7. Allow the sander to run for several minutes
while observing the conveyor belt tracking
and readjust if necessary.
8. Turn off the conveyor belt and re-install
emergency stop cover.
Feed Rate
The feed rate is infinitely variable within the
provided range, in order to meet the sanding
requirements of a wide variety of materials.
Selecting a proper feed rate is largely a matter
of experience. In general, soft woods require a
higher feed rate, while hard woods require a
lower feed rate.
Change the feed rate only
while the conveyor belt is running. Failure to
comply may cause damage to the gearbox.
Adjust the feed rate with the selector knob on
the worm gear reducer (Figure 15). Turn the
selector knob clockwise to decrease the
conveyor belt speed, counterclockwise to
increase it.
Pressure Bar Adjustment
The front and rear sets of pressure bars have
been factory adjusted. This setting should,
however, be checked before operating the
sander.
The pressure bars should be parallel to the
conveyor table with equal pressure on each end,
and are set slightly below the level of the
sanding belt.
If the ends of the workpiece are sniped, the front
pressure bars are too low. The pressure should
be enough to firmly hold the workpiece against
the conveyor, but not so hard that the ends of
the workpiece spring up after clearing the bar.
