The JDS-12B disc sander is rated 115V/230V,
Prewired 115V.
If you want to run the JDS-12B on 230V refer to
the wiring diagram found on the inside of the
switch box cover (F, Figure 8).
Before hooking up to the power so urce, make sure
that the switch is in the off position.
It is recommended that the sander, when operated
at 115 volts, be connected to a dedicated,
minimum 20 amp circuit with a 20 amp circuit
breaker or time delay fuse. W hen operated at 230
volts, connect the sander to a dedicated, minimum
10 amp circuit with 10 amp circuit breaker or time
delay fuse. Local codes take precedence over
recommendations.
Dust Collection
The disc sander has a built in fan designed to suck
the saw dust away from the sanding disc and
exhaust through the inlet (C, Figure 7). For best
results hook the sander to JET’s optional
accessory canister filter (#708434).
The sander can also be attached to a dust
collector using a 4” diameter hose and clamp. JE T
offers a wide variety of hoses, adapters and dust
collectors.
Canister Filter (optional accessory)
1. Remove the inlet port that came with the
sander.
2. Mount the plastic elbow (A, Figure 9) to the
sander using the same hardware (B, Figure 9)
from the inlet port.
3. Connect the filter (C, Figure 9) to the elbow
and turn counter-clockwise so that it locks in
place.
Static electricity will build up
in the filter during operation. The filter ground
must be attached to the machine ground, a nd
to the filter. Failure to comply may result in
fire/loss of property, or personal injury.
4. Remove the screw (D, Figure 9) from the
sander base. Attach the end of the grounding
wire to the screw and thread back in to the
base.
5. Attach the grounding clip (E, Figure 9) to the
metal part of the filter. This will prevent static
electricity from building up in the filter.
Figure 9
Cleaning the Filter
Wearing a particle
mask/respirator for protection against fine dust
particles during cleaning is highly
recommended.
Clean the canister filter frequently to keep the
sander’s performance at its optimum. To clean:
1. Disconnect the machine from the power
source.
2. Take off the grounding clip and remove the
filter (C, Figure 9) by turning clockwise.
3. Empty the contents into an appropriate
container.
4. The filter can be cleaned with a low pressure
air hose. Blow from the outside of t he filter to
clean the dust particles. For best results check
and empty the filter frequ ently.
5. Install the filter and reattach the grounding clip.
