Changing Spindle Speeds; Return Spring Adjustment; Work Light (J-2500 And J-2530 Only) - JET J-2500 Instrucciones De Operación

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.
Note: The chart in Figure 12 is for models J-2500
and J-2530 only.
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.

Return Spring Adjustment

The return spring is adjusted at the factory and
should not need further adjustment. If adjustment is
deemed necessary, follow the steps below while
referring to Figure 13:
1. Unplug the machine from the power source.
2. Loosen two hex nuts (A). Do not remove.
3. Firmly hold the coil spring cover (B).
4. Pull out the cover and rotate until the pin (C) on
the return spring plate engages the next notch in
the coil spring cover. Turn the cover clockwise to
decrease tension and counter-clockwise to
increase tension.
5. Tighten two hex nuts (A). Do not over-tighten. Nuts
should not contact the housing when tight. The hex
nuts should be tightened against each other.

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.

Work Light (J-2500 and J-2530 only)

Install a light bulb, no larger than 60 watts into the
socket accessed from beneath the head. The rocker
switch controls the light switch (D, Fig. 13).
