leaky Dust Collector filter hoods for optimal performance:
Filter Hoods on Dust Collectors are designed to allow air
to pass through them, while capturing fine dust particles
inside. This process is made more efficient through use, as
a "cake" of dust forms on the inside of the Hood, allowing
it to trap finer and finer particles as the cake builds-up.
Unfortunately, many Dust Collectors are not designed to capture
ultra-fine particles right out of the box and therefore, some
of these particles may slip through the Hood until a sufficient
cake forms (this is not the case with Shopsmith's DC-3300
you're experiencing this problem, turn on your Collector until
the Hood is fully "inflated". Turn it off and briskly smack
the sides of the Hood several times to dislodge the dust from
the Hood (or un-zip it) and lightly spray the inside
with aerosol cooking spray. Re-attach (or close) the Hood
and try again. If particles still leak through, repeat the
process until they stop.
the dust cake forms on he inside of the Hood, you should have
no more problems.
