sanding passes to prevent gouges. When the drum moves from sanding a wide surface
to sanding a narrow surface, the load on the motor will be reduced, and the drum will
speed up, causing a gouge.
• DO NOT edge sand boards. This can cause boards to kickback, causing serious personal
injury. Edge sanding boards also can cause damage to the conveyor belt and sandpaper.
• When sanding workpieces with a bow or crown, place the high point up (prevents the
workpiece from rocking) and take very light passes.
• Feed the workpiece at an angle to maximize stock removal and sandpaper effectiveness,
but feed the workpiece straight to reduce sandpaper grit scratches for the finish passes.
Stock Inspection and Requirements
Some workpieces are not safe or may require modification before they are safe to sand.
Before sanding, inspect all workpieces for the following:
•
Material Type:
This machine is intended for ONLY sanding natural and man-made wood
products. This machine is NOT designed to sand metal, glass, stone, tile, drywall or
cementitious backerboard.
•
Foreign Objects:
Nails, staples, dirt, rocks and other foreign objects are often embedded
in wood. While sanding, these objects can become dislodged and tear the sandpaper.
Always visually inspect your workpiece for these items. If they can't be removed, DO
NOT sand the workpiece.
•
Excessive glue or finish:
Sanding workpieces with excess glue or finish will loadup the
abrasive, reducing its usefulness and lifespan.
•
Workpiece Dimensions
: DO NOT sand boards less than 8" long, 2" wide and 1/8" thick to
prevent damage to the workpiece to reduce the risk of your hands contacting the
sandpaper.
Depth of Cut
The optimum depth of cut will vary based on the type of wood, feed rate, and sandpaper grit.
Under most sanding conditions, the depth should not exceed 0.006" (0.15 mm) (approx.
1/8
turn of the handwheel). Each full turn of the crank handleraises the conveyor table
approximately 1/16
”
(1.5 mm). Attempts to remove too much material can cause jamming,
wood burning, rapid paper wear or tearing, poor finish, belt slippage, and motor damage.
To set the depth of cut:
1. Rotate the crank handle until the conveyor table is well below the sanding drum, place the
workpiece on the table, then raise the table, until the front pressure roller just touches the top
of the workpiece.
Note:
When adjusting the table to sand a thicker workpiece, lower and then raise the table to
remove backlash from the adjustment mechanism. If the table is lowered too far, the
