Figure 12
Figure 13

Electrical Connections
All electrical connections
must be done by a qualified
electrician. All adjustments or repairs must
be done with the dust collector disconnected
from the power source, unplugged. Failure
to comply may result in serious injury!
The JC-3 is rated at 3 Phase 230V. The JC-3 is
not supplied with a plug. Use a plug and outlet
rated at least 20amps. The circuit for the
machine should also be protected by at least a
20 amp circuit breaker or fuse.
Keep in mind that a circuit being used by other
machines: tools, lights, heaters, etc. at the same
time will add to the electrical load. A dedicated
circuit to the dust collector will give you the best
results since dust collectors are generally used
at the same time other tools are running.
Before hooking up to the power source, make
sure that the switch is in the off position.
Turning the Machine On &

Cleaning the Filter Bag – Filter Bag
Model
Wearing a particle mask or
respirator for protection
against fine dust particles during cleaning is
highly recommended.
During first use and after cleaning, the filter bag
may allow some dust to escape. This is normal
and will stop after a short period of time.
Clean both the filter and collector bags
frequently to keep the collector's performance at
its optimum. To clean:
1. Disconnect the machine from the power
source.
2. Unhook the filter bag from the hanger and
shake the bag so that the majority of the
dust falls into the collector bag.
3. Loosen the retaining strap, and remove the
filter bag from the housing.
4. Turn the bag inside out and clean.
5. Turn the bag outside in and re-attach to the
housing using the retainer strap to secure.
Removing the Collector Bag – All
Models
1. Disconnect the machine from the power
source.
2. Remove the collector bag by pushing the
ring of the collector bag upwards and
pulling the bag out at an angle.
3. Empty the contents into an appropriate
container.
4. Turn the bag inside out and clean.
5. Turn the bag outside in and insert into the
housing.
To replace the collector bag, refer to the
Collector Housing and Collector Bag section.
Use the proper type hose to connect the dust
collector to the machine being operated. Dryer
vent hose is not acceptable for this purpose.

its optimum.
To clean the filter, turn the handle a couple of
rotations so the dust falls into the collector bag.
