Setting Conveyor
Speed
The Conveyor Speed Control dial (see Figure 16)
allows you to set the conveyor speed from 0–10
(0–20 FPM). The correct speed to use depends
on the type of stock you are using (hardwood vs.
softwood) and the stage of finish you are at with
that workpiece.
As a general rule, a slower speed will sand the
surface smoother, but runs the risk of burning
the wood; a faster speed will remove material
faster, but runs the risk of overloading the motor.
Use trial-and-error to determine the best settings
for your specific applications.
1.
Turn Conveyor Speed Control dial (see
Figure 16) to "0," and then turn conveyor
motor ON.
2.
Turn Conveyor Speed Control dial
clockwise to increase conveyor speed.
— If conveyor speed is too high, turn dial
counterclockwise to decrease conveyor
speed.
Overloading the motor or pushing the sander
to failure weakens the electrical system.
Repeatedly doing so is abuse to the machine
that will cause motor, capacitor, or circuit
breaker damage, which is not covered under
warranty.
Monitoring Sanding
Load
The sanding load meter, shown in Figure 17,
displays the amperage draw of the sanding
drum motor. The number shown increases
when you increase the load on the sanding
drums and decreases when you decrease the
load. Use this meter to avoid overloading your
machine with too heavy of a cut.
IMPORTANT:
NEVER exceed 25 amps—this
is the maximum that your machine can safely
handle!
Since various types of stock will react
differently with various loads, use trial-and-
error to determine the best settings for your
applications. Always start with a small load
and work your way up. We recommend that
you do not push your machine to its maximum
load; instead, make multiple passes or install a
coarser grit paper.
