7.
Lower drum to securely hold straight‐edge in
place. See Figure 6‐4. Raise infeed/outfeed table
until table surface is slightly below conveyor belt
surface. Tighten screws on that side.
8.
Reposition straight‐edge to other side of table
and repeat.
9.
Loosen screw (HP6) and rotate eccentric cam
(HP8) until it contacts lip of table bracket. Do this
on both sides of infeed table. This ensures infeed
table will remain level with conveyor table each
time it is returned to operating position. Tighten
screws (HP6).
If stock being sanded is bowed, warped or otherwise
inconsistent, be sure tables are lower than top of
conveyor table.
If stock slips on conveyor, the tables may be
positioned too high. Lower tables to allow stock to
remain in contact with conveyor.

Dust collection
Dust collection is mandatory for a safe work
environment and extended abrasive life. The machine
is equipped with a 100mm dust collection port.
Secure a 100mm dust collection hose to the port with
a hose clamp (Figure 6‐5), and connect to a dust
collector (minimum 560m3/h).
Figure 6‐5 (hose and clamp not included)

Installing abrasives
Proper attachment of the abrasive strip to the drum
is critical to achieving top performance from your
drum sander.
An 80‐grit, 76mm wide abrasive strip is pre‐installed
on the drum.
(TIP: If you are using an after‐market abrasive, use a
new JET‐supplied abrasive as a template to quickly
cut a new strip.
To install abrasive strip:
1.
Press fastener lever (Figure 6‐7) on outboard
(left) end of drum, and insert tapered end of
abrasive through slit in fastener, as shown. Insert
approximately 75mm of abrasive strip into
fastener. Align tapered edge of abrasive strip
with left edge of drum.
Figure 6‐7
2.
Release fastener lever to secure end of strip.
3.
Begin wrapping abrasive around drum. The
tapered edge of strip end should follow as close
as possible to edge of drum.
4.
Continue to wrap abrasive in spiral fashion by
rotating drum with one hand and guiding strip
with the other. See Figure 6‐8.
Successive windings of strip must
not have any
overlap.
They should be flush with previous
windings or with a slight gap between.
