Outlet.Flap
Outlet Flap
If one dust collection bag fills faster than the other, adjust
the metal flap on the inside of the outlet, as shown in
Figure.21. Pushing the flap to one side or the other diverts
the airflow and equalizes the rate the bags fill with dust.
To.access.the.flap,.do.these.steps:
1. DISCONNECT MACHINE FROM POWER!
2. Release one of the clamps and remove an upper
filter bag.

of collection bags.
4. Re-install the top bag with the clamp.
Machine.Storage
When the dust collector is not in use, unplug the
power cord from the power source. Place the cord away
from potential damage sources, such as high traffic areas,
sharp objects, heat sources, harsh chemicals, water, damp
areas, etc.
Duct.Material
You have many choices regarding main line and branch
line duct material. For best results, use metal duct for
the main line and branch lines, then use short lengths
of flexible hose to connect each machine to the branch
lines.
Plastic duct is also a popular material for home shops.
However, be aware that there is a fire or explosion hazard
if plastic duct material is used for dust collection without
being grounded against static electrical charge build-up.
This topic will be discussed later in this section. Another
problem with using plastic is that it is less efficient per
foot than metal.

components.
The popularity of plastic duct is due to the fact that it
is an economical and readily available product. It is also
simple to assemble and easily sealed against air loss. The
primary disadvantage of plastic duct for dust collection is
the inherent danger of static electrical build-up.
