Setting Feed Speed
The feed belt motor offers variable speeds from 15 to
49 FPM. Figure 17 points out the variable conveyor feed
speed control knob.
To change the feed belt speed do these steps:
1. Start the conveyor.
2. Rotate the control knob to the required conveyor
speed as indicated by the speed indicator. Only
adjust the speed when the conveyor is operating.

Using the Amp Draw
Meter
The amperage draw meter ( Figure 18 ) is used to keep
the machine from being overloaded during sanding
operati ons.
As a general rule, always start with a shallow sanding
depth and carefully increase the sanding depth. Keep the
amp load in the green range during operation. Generally,
the normal depth of cut is no more than 1 ⁄
64
" or 0.016" for
a 37" wide board using coarse sandpaper. DO NOT work
your machine in the red zone as shown on the Amperage
Load Chart. If operated in the red zone, the motor will
lose RPM, the start capacitor will energize, and capacitor
or motor damage will occur.
Amp load will be directly affected by many factors such
as feed rate, depth of cut, wood type, sandpaper grit,
and workpiece width.

Selecting Sandpaper
When selecting sandpaper, keep in mind that the Model
W1737/W1738 accepts only 37" wide x 60" long belts.
Consider the type of work, the species of wood and
the stage of finishing. When choosing which sandpaper
to use, use these grit numbers as a general guide to
sandpaper type:
• 60 Grit or less ........................Coarse
• 80-100 Grit ............................Medium
• 120-150 Grit...........................Fine
Note: For best results, do not increase grit numbers
more than 50 on any successive pass.
NOTICE
DO NOT VOID MACHINE WARRANTY!
Keep the amp draw within the GREEN
zone shown on the AMP LOAD CHART.
If you operate the sander in the RED
zone, capacitor or motor failure will
occur and will not be covered under
warranty.
