Changing Spindle Speeds - Jet J-2500 Operating Instructions And Parts Manual

Changing Spindle Speeds

A spindle speed and pulley/belt arrangement chart
for all models is found on the inside of the pulley
cover (D, Fig. 11). Refer to this chart whenever
changing speeds.
The charts are also displayed in Figures 12 and 13.
To change spindle speeds:
1. Unplug the machine from the power source.
2. Loosen two bar knobs (E, Fig. 11) found on
each side of the head assembly.
3. Rotate the tension adjuster (F, Fig. 11)
clockwise to bring the motor base as close to the
head as possible.
4. For desired speed, change the location of belts
per pulley/belt arrangement chart.
5. Rotate the tension adjuster (F. Fig. 11)
counterclockwise to tension the belts.

6. Tighten two bar knobs (E, Fig. 11). Belts are
properly tensioned when finger and thumb
pressure midway between the two pulleys
causes approximately ½" deflection.
