WHAT FACTORS AFFECT SANDING OPERATIONS?
A. SANDING BELT GRIT
1. 36 grit – Used for very aggressive stock removal, glue removal, or for sanding rough boards. Leaves a rough
finish.
2. 60 grit – Used for heavy stock removal and rough surfaces, and for truing warped material. Leaves a rough
finish.
3. 80 grit – Used for general purpose sanding, stock removal, surfacing, and rough finishing. Leaves a marked
finish.
4. 120 grit – Used for minimal stock removal and for finishing. Leaves a fine marked finish.
5. 180 grit. – Used for fine finishing. Leaves a smooth finish.
6. 220 grit – For very fine finishing. Leaves a very smooth finish.
For best results, sand first with a coarse grit belt, and work toward a finer grit belt.
IMPORTANT: Sanding progression should not exceed more than two belt grits at one time. Watch for the sawdust
loading and dulling of the grit. The extra load will cause the sander to work inefficiently.
B. MAXIMUM AND MINIMUM DIMENSIONS FOR WORKPIECE
Maximum thickness: 4" (102 mm)
Minimum thickness: 1/32" (0.8 mm)
Maximum width: 18” (457 mm) in one pass - 36” (914 mm) in two passes.
Minimum width - None - (IMPORTANT: Be certain with narrow stock that the stock width is equal to, or greater
than, the stock thickness).
Maximum length: Infinite. For heavy workpieces or workpieces longer than 4 feet use an accessory Infeed/Outfeed
Table or a roller stand for additional support.
C. WIDTH OF BOARD
As board width increases the load on the belt and motor also increases. This additional loading can be reduced by:
a. reducing the conveyor belt speed.
b. reducing the depth of stock removal.
NOTE: The sander will remove stock to a maximum width of 18" (46 cm) in one pass.
D. TYPES OF WOOD
Hardwoods (oak, hickory, cherry), knots, rosin, or wet wood all place a heavy load on the sander. To make your
sander work more efficiently:
a. reduce the conveyor belt speed.
b. reduce the depth of stock removal.
E. CONVEYOR BELT SPEED
The conveyor belt speed is 0 - 12 feet per minute.
To control the speed of the conveyor belt, turn the knob counter-clockwise to slow it down and clockwise to speed
it up.
Stock can be removed more quickly by using a fast speed, but the machine works much harder, and the wood is
left with a rougher finish. Slowing the speed will lighten the load of the sander, and make the finish better, but it
will increase the sanding time.
WHEN DO I CHANGE THE DRUM SPEED?
The machine has two drum settings:
a. High Speed (3300 SFPM). This setting should mostly be used with a finer grit belt with the conveyor belt speed
set to very slow. The material removal should be set at a very low amount, with increases not to exceed 1/16
of a handwheel turn. Example: A 1/4 turn is 90°, 1/8 turn is 45°, 1/16 turn is 22.5°.
b. Low Speed (2210 SFPM). Used for general purpose sanding, stock removal, surfacing, and rough finishing.
The machine is shipped from the factory set on the low speed. To change to the higher speed, refer to "CHANGING
DRUM SPEEDS/REPLACING DRIVE BELT" in this manual for instructions.
