Changing Spindle Speed
Referring to Figure 4:
The JWS-25X Shaper is equipped with pulleys that
allow you to change the spindle speed.
The
drive belt
(C) placed on the upper pulley
position (A) provides a 7,500 RPM spindle speed.
The belt placed on the lower pulley position (B)
provides a 10,000 RPM spindle speed.
To change speed:
1. Disconnect the machine from the power
source.
2. Open the door located on the right side of the
cabinet.
3. Remove the belt tension by turning the
tension
handle
(D) fully counterclockwise. This allows
the
motor
(E) to swivel on its mounting hinge.
4. Move
the
drive belt
(C) as desired to the A or B
position (Figure 4 shows belt in A position).
5. Turn
the
tension handle
(D) clockwise to re-
secure the
motor
(E) and place tension on the
drive belt.
Belt Replacement
Replace the
drive belt
(C) as follows:
1. Disconnect the machine from the power
source.
2. Open the door located on the right side of the
cabinet.
3. Turn the
tension
handle
(D) fully counter-
clockwise. This allows the
motor
(E) to swivel
on its mounting hinge and removes sufficient
belt tension to permit easy removal.
4. Remove
the
drive belt
(C).
5. Replace
belt.
6. Turn
the
tension handle
(D) clockwise to re-
secure the
motor
(E) and place tension on the
drive belt.
Figure 4
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 located on the right side of the
cabinet.
3. Adjust
tension
handle
(D) clockwise to
increase belt tension or counterclockwise to
decrease belt tension.
