Changing Cutter Speed
Referring to Figure 18:
The Model 2700 Shaper is equipped with pulleys that allow you to change the spindle speed. The belt (B) placed on the upper pulleys (as shown in Figure 16) provides 7,500 RPM spindle speed. Placing the belt on the lower pulleys provides 10,000 RPM spindle speed.
To change speed (refer to Figure 16):
1.Disconnect the machine from the power source.
2.Open the door of the cabinet.
3.Remove the belt tension by moving the belt tension handle (A) to the unlock (left) position. This allows the motor (E) to swivel on its mounting hinge.
4.Move the drive belt (B) to the other set of grooves (C).
5.Lock the belt tension handle (A), securing the motor (E) and placing tension on the drive belt (C).
Drive Belt Tension
Referring to Figure 18:
The drive belt should have sufficient tension to prevent slippage when the machine is in operation. If the tension on the belt needs adjustment:
1.Disconnect the machine from the power source.
2.Open the door of the cabinet.
3.With a 17mm wrench, loosen the lock nut (G) on the belt tension assembly (refer to inset for loosening direction).
4.Adjust the hex bushing (F) with a 17mm wrench (refer to inset for adjustment direction) for proper tension on the belt (B). The tension handle (A) must be in the locked position (right) while performing this step.
Note: Two 17mm wrenches are required for the next step.
5.Maintain the position of the hex bushing (F) with one wrench while tightening the lock nut (G) with the other.

Belt Replacement
Referring to Figure 18:
Replace the drive belt (B) as follows:
1.Disconnect the machine from the power source.
2.Open the door of the cabinet.
3.Remove the belt tension by moving the belt tension handle (A) to the unlock (left) position. This allows the motor (E) to swivel on its mounting hinge.
4.Work the drive belt down all the way past the pulleys.
5.Continue sliding the belt down on the left side until it is free from the spindle (C), then remove the belt over the top of the motor pulley (D).
6.Install the new belt by following these steps in reverse.
