Grizzly G0459P Variable Speed Sanding, To adjust the conveyor speed, To sand a workpiece

Variable Speed Sanding

The variable speed knob allows you to increase the feed rate from 2.47–17.3 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish you are at with that workpiece.

As a general rule, a slower feed rate sands the surface smoother, but runs the risk of burning the wood; a faster feed rate removes material faster, but runs the risk of overloading the motor.

Use trial-and-error to determine the best settings for your specific applications.

To adjust the conveyor speed:

1.Start the conveyor.

2.Rotate the variable speed knob (Figure 16) clockwise to increase the feed speed, or counterclockwise to decrease the feed speed.

DO NOT sand more than one board at a time. Minor variations in thickness can cause one board to be propelled by the rapidly spinning sanding drum and ejected from the machine. NEVER stand directly in front of the outfeed area of the machine. Failure to do so could result in severe personal injury.

To sand a workpiece:

1.Adjust the table height according to the instructions in Depth of Cut on Page 21.

2.Start the dust collector, turn the sander ON, and start the conveyor.

3.Feed the workpiece through the sander. Retrieve the workpiece by standing at the side—not at the outfeed end.

4.Run wide stock through two or three times without adjusting the table height. Turn the stock 180° between passes to ensure an even cut.
