SECTION 8: SERVICE ADJUSTMENTS
Keep loose clothing out of the way of machinery and keep hair pulled back.
Disconnect power to the machine when perform- ing any maintenance or assembly. Failure to do this may result in serious personal injury.
Wear safety glasses dur- ing the entire assembly process. Failure to com- ply may result in serious personal injury.
Oscillation Timing
The first step in adjusting the oscillation is timing the side to side movement the belt makes when oscillating. The belt should take the same amount of time to travel to one side as it did the other.
Keep your hands clear of the sanding belt when making the adjustments in this step. The sandpaper is designed to remove a lot of material quickly whether it is wood or skin!
To time the oscillation movement:
1.Open both access doors to the upper part of the machine so you can view the belt move- ment. The sanding belt should also be on the rollers and tightened. Turn the sanding belt ON.
2.Count the amount of time it takes the belt to move from one side to the other. If the oscil- lation balance is correct, the belt will move from one side to the other in even intervals. If the balance is not correct, the belt may move to one side very quickly, then very slowly to the other.
3.If the belt immediately moves too far and shuts off the machine, then loosen the oscil- lation timing control knob shown in Figure 20 and move it toward the front or rear of the machine to rotate the eccentric.
4.Loosen the belt tension, rebalance the sand- ing belt and retighten the belt tension. Repeat steps 2 and 3.
