Dust
Collector

For Your Own Safety

• Please read this Manual before operating your Foredom Dust Collector.

• Always wear eye protection while using power tools.

• NEVER use the Dust Collector to pick up ammable liquids or any liquids and

do not use near ammable or combustible liquids as re or explosion can occur.

• ALWAYS operate the Dust Collector with a lter collection bag properly in

place that has been inspected for any damages. Sawdust and other debris can
cause inhalation problems and are potentially re and explosion hazards.

• ALWAYS disconnect the Dust Collector from a power source when removing or

replacing lter bags or doing any sort of maintenance.

MADC20 Dust Collector

Includes:

• Cyclone dust collector with

collection bowl

• 5′ Vacuum Hose Assembly

• Top Connector

• 2 HEPA Filters (1 installed)

• Remote Cord for MALC15

• Remote Switch with 9′ Cable

• Power Cord

• Exhaust Deector

Assembly

1. Remove the unit and all components from box and

cross check with list above to make sure that there is
nothing missing.

2. Lay the dust collector on its left side and remove the
four screws to mount the cyclone with bowl.

3. Align the mounting holes of the cyclone with the
dust collector, insert screws and tighten.

4. Place the dust collector upright on its casters.

5. Insert the Top Connector into the top of the cyclone

and top of the dust collector.

6. Connect the Vacuum Hose into the Hose Port on
the cyclone and the other end into a work chamber,
shmouth or other dust collection device.

7. Check to make sure that the power switch is in the
off position and plug the power cord into Power Inlet.
The Power Switch has 3 positions with ‘Manual On’ at
the top, ‘Off’ in the center, and ‘Remote On/Off’ for the
bottom. The red light is illuminated when the unit is on.

8. Plug the Remote Switch Cable into the Inlet labelled
‘Remote’ and turn on the unit. Turning the Vacuum
Speed knob clockwise will increase the speed of the
motor and cfm of air moving through the unit. The fan
speed selected will depend on the job at hand.

9. The dust collector is best used near the work
area, usually on the oor beneath your bench. A 5’
long vacuum hose is supplied with the dust collector.
Additional extension hoses are available (see back),
but keep in mind that longer hose lengths will

reduce the suction of the unit.

10. The remote control switch has a holder that has a
(PSA) pressure sensitive adhesive backing. Just peel off
the paper and press down the remote holder in a con­venient out of the way location near your work area.

Operation and Maintenance

Use the Dust Collector for ltering dust and
debris from grinding, sanding, bufng ling
and polishing on wood, stone, diestone, metal
and plastic. The unit is designed to run with the
cyclone which gives you ten times the lter bag
life, decreases maintenance and improves the
performance of the unit.

Operation and Maintenance continued
Thermal shut off prevention:

The Dust Collector motor has a safety electronic
thermal overload

prevention circuit which turns
the motor off if it gets too hot. This can be caused
by both lters being clogged, especially the
canister lter MADC208 which is located under the
HEPA lter bag.

1. Periodically check the Clear Dust Collection Bowl
for build up. When it is half full you need to empty it.
Precious metals will be collected here for later rening.
Other debris should be disposed of properly. To release
the bowl, ip up the three spring latches. When the
bowl is clean, place it back into position and reattach
spring latches.

2. Changing the HEPA Filter Bag, loosen (do not

remove), the four thumb screws located on the top
of the dust collector and turn the cover clockwise to
release the cover slots from the thumb screws. Pull the
lid with the lter bag from the dust collector.
Next, unscrew and
remove the two thumb
screws that hold the
lter bag in place. Pull
off the old lter bag
and insert the new
bag over the mounting
tube and screw on the
thumb screws to hold
the new lter in place.

Retighten the thumb screws.

Connector tubing. Then loosen the thumb screws to the
lter chamber compartment and twist it until the lid can
be removed. You should replace
the HEPA lter bag at this time.
Then look down into the empty
chamber and unscrew the knob
screw on the canister lter lid
and carefully remove the metal
and rubber washers and lid. You
can now lift out the canister
lter and replace it. Reassemble

and start working again.

4. Changing a Fuse – If the unit is not power­ing on, you should check the fuse. The fuse and

spare fuse (8 amp, 5 x 20mm,
medium time delay, Bussman
GMC-8A or equivalent) are stored

Active
Fuse

in the AC power cord receptacle
on the front of the unit. To check
or change the fuse, follow these
directions:

Remove the power cord

from the Power Inlet to expose the

Spare
Fuse

fuse holder drawer. Use the blade of
a small screwdriver in the slot of the
fuse holder and gently pry outward.
The active fuse is in the back of the
drawer and a spare fuse is in the front
compartment. If the glass case of
the active fuse is darkened, the fuse
is blown. From the underside of the

Pry open
fuse drawer

drawer, push out the blown fuse using a small screwdriver.

Do not use a higher am­pere fuse. MAX Fuse size is
8 Amps.

5. Changing Motor

Brushes

Power decreases or intermit­tent power may be a sign that
the motor brushes need to be
replaced.

To replace them be
sure to unplug the
power plug and the
remote plug.

A. Use a 2mm hex key to un­screw the 10 screws holding
the front panel on the unit,
placing it to the side without
disconnecting the wires.

B. Remove the two Philips head motor mounting screws
on the motor mounting bracket.

C. Carefully
slide the
motor out of
the housing.
