Sanding Tips
•
Avoid sanding a workpiece more than is
necessary, since doing so will unnecessarily
decrease belt life and cost you more money
over time.
•
Only sand with as slow of feed speeds as
necessary to meet your sanding goals. In
other words, avoid running the sander faster
than is necessary. Increasing feed speeds
beyond the required level can decrease the
quality of the finished product.
•
As a general rule, use the sanding drum for
the initial heavy sanding pass, then use a
combination of the platen and drum for the
intermediate pass, and the platen alone for
the final sanding passes.
•
As a rule-of-thumb, sand with progressively
higher grit numbers in increments of 50 or
less.
•
Replace sandpaper with a higher grit to
achieve a finer finish (refer to Installing/
Changing Sanding Belts on Page 35).
•
When making multiple passes on the
workpiece, avoid raising the conveyor table
more than 0.015" (nearly one turn of the
height handle or 3 touches of the Table Up
key) per each pass.
•
Reduce snipe when sanding more than one
board of the same thickness by feeding them
into the machine with the front end of the sec-
ond board touching the back end of the first
board (aka "Butt Feeding").
•
Feed boards into the machine at different
points on the conveyor to maximize sandpa-
per life and prevent uneven belt wear.

DO NOT sand boards less than 12" long, 2"
wide and

•
Extend the life of the sandpaper by regularly
cleaning the sanding belt (refer to Cleaning
Sanding Belt on Page 44).
•
DO NOT edge-sand boards. This can cause
boards to kickback, causing serious personal
injury, and cause damage to the conveyor
belt and sanding belts.
•
Only use the amp load meter to keep the
motor from overloading—that is its main
purpose. Avoid using the amp load meter to
monitor how much material is being removed,
as this can lead to problems, including belts
loading, burning, and poor quality sanding
results.
•
Make sure to adjust platen position accord-
ingly when changing grit sizes.
•
The faster the feed rate you use, the faster
your sanding belts will wear out.
