Variable Speed

 

Sanding

 

 

 

 

 

 

The variable speed knob allows you to increase the feed rate from 2–12 FPM. The correct speed to use depends on the type of stock you are using (hardwood vs. softwood) and the stage of finish with that workpiece.

As a general rule, a slower feed rate will sand the surface smoother, but runs the risk of burning the wood; a faster feed rate will remove material faster, but runs the risk of overloading the motor or damaging the sandpaper.

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

To adjust the feed belt speed:

1.Turn ON the feed belt (DO NOT adjust con- veyor speed when the conveyor motor is OFF).

NOTICE

Adjusting the variable speed when the con- veyor motor is OFF can damage the V-belt and the adjusting mechanism.

2.Rotate the variable speed knob (Figure 17) counterclockwise to increase the feed speed, or clockwise to decrease the feed speed.

Figure 17. Variable speed knob.

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 19.

2.Make sure the filter bag is secure (or start the dust collector, if connected) and turn the sander ON.

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 evenly sanded surface.

NOTICE

Over-bogging the motor or pushing the sander to failure weakens the electrical sys- tem. Repeatedly doing so is abuse to the machine that will cause motor, capacitor, or thermal breaker damage, which is not cov- ered by the warranty.
