OPERATIONS
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
operations.
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.
