Dust Collection
Dust collection is mandatory for a safe work
environment and extended abrasive life. The 22-
44 Plus is equi pped with a 4” dust collection por t
at t he top of the dust cov er. It i s designed t o be
used with standard 4” dust collection hose
connected to a high volume dust collector
(minim um 500 CFM ), as shown in Fi gur e 7.
WMH Tool Group offers a variety of Dust
Collectors and Air Filtration Units. Contact your
local distributor for more information.
Installing Abrasives
An 80-grit abrasive strip is already installed on
the drum of your sander. Page 23 offers
information on other abrasives available and
their recommended uses.
Proper attachment of the abrasive strip to the
drum is critical to achieving top performance
from your drum sander. Abrasive strips do not
have to be pre-measured. The end of the roll is
first tapered and attached to the left (outboard)
side of the drum. Then the strip is wrapped
around the dr um, and the second taper i s m ade
for attachment to the right (inboard) side of the
drum.
NOTE: When using Ready To WrapTM
abrasives, not all of the steps below are
necessary. You can use the original abrasive
strip mounted to the drum as a template for
cutting your own strips.
1. Mark and cut a taper at one end of the roll
as shown in Figure 8. Because the tapered
end shoul d use al l of the left (out board) slot
width, its end must be trimmed back as
shown.
2. Raise t he fastener l ev er (D, Figure 9) on t he
outboard end of drum, and insert the
tapered end of the abrasive (E, Figure 9) so
that it uses most of the width of the slot.
Release the fastener lever to securely hold
the str ip end to t he fastener.
3. Begin wrapping the strip around the drum.
The tapered edge of the strip end should
follow the edge of the drum.
4. Continue to wrap the abrasive in a spiral
fashion by rotating the drum with one hand
and guiding the strip with the other (Figure
10).
