ADJUSTMENTS & OPERATION
Changing Cutter Speed
This Industrial Shaper is equipped with pulleys that allow you to change the
spindle speed. The belt (A) Fig.18 placed on the upper pulleys (B) provides
5,000 RPM spindle speed. Placing the belt on the middle pulleys (C) provides
7,000 RPM spindle speed. Placing the belt on the lower pulleys (D) provides
10,000 RPM spindle speed, refer to Fig.19 for belt position illustration.
To change speed:
1. Disconnect the machine from the power source.
2. Open the door of the cabinet.
3. Release belt tension by moving the belt tension handle (A) Fig.20 to the
unlock (left) position as shown. This allows the motor (B) to swivel on its
mounting hinge.
4. Move the drive belt (C) to the other required set of pulleys.
5. Lock the belt tension handle (A), securing the motor (B) and placing tension
on the drive belt (C).
Drive belt Tension
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 17 mm wrench, loosen the lock nuts (D) Fig.20 on the belt tension
assembly.
4. Adjust the hex. bolt (E-not visible) with a 17 mm wrench to tension the belt
(C). The tension handle (A) must be in the locked position (towards the right)
while performing this step.
Note: Two 17 mm wrenches are required for the next step.
5. Maintain the position of the hex. bolt (E) with one wrench while tightening the
lock nuts (D) with the other.
belt Replacement
Replace the drive belt (C) Fig.20 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 (B) 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,
then remove the belt over the top of the motor pulley.
6. Install the new belt by following these steps in reverse.
