Setting Feed Speed
The conveyor belt motor offers two conveyor speeds: 13 and 16 FPM (Feet per minute). Figure 13 points out the two sprocket ratios available.
To change the conveyor belt speed do these steps:
1.DISCONNECT THE SANDER FROM POWER!
2.Remove the conveyor belt motor cover by taking out the cap screw that secures it.
3.Loosen the four bolts at the motor mount and slide the motor up. Pull the chain off of the sprocket that it is currently on.
4.Place the chain on the next sprocket and slide the motor down to tighten the chain.
5.Hold the motor down and tighten the motor mount bolts at the same time.
6.Replace the motor cover before reconnecting the sander to the power supply!
Using the Amp Draw
Meter
The amp draw meter (Figure 14) is used to keep the machine from being overloaded during sanding operations.
As a general rule, always start with a shallow sand- ing depth and carefully increase the sanding depth. Keep the amp load in the green range during operation. Generally, the normal depth of cut is no more than 1⁄64" or 0.016" for a 25" wide board using coarse sandpaper. DO NOT work your machine in the red zone as shown on the Amperage Load Chart. If operated in the red zone, the motor will lose RPM, the start capacitor will ener- gize, and capacitor or motor damage will occur.
Amp load is directly affected by many factors such as feed rate, depth of cut, wood type, sandpaper grit, and workpiece width.

NOTICE
DO NOT VOID MACHINE WARRANTY! Keep the amp load within the GREEN zone shown on the AMP LOAD CHART. If you operate the sander in the RED zone, capacitor or motor failure will occur and will not be covered under warranty.
