Mounting Drum Belts
First, deflate bladder and check for a directional arrow on the inside of
the drum belt and match it with the arrow located on the outside flange of
the pneumatic drum. Slip on the selected drum belt and center it over the
drum. To secure belt, inflate bladder by applying air source to valve stem.
Inflate until drum belt feels snug, without over-inflating.
NOTE: a) Do not inflate bladder above 15 psi.
b)
When using shop air, be sure to use an approved blow-
gun
equipped with a safety nozzle.
COOLCUT
™
Drum Belts
These belts are made with premium zirconium and aluminum oxide
abrasive grains that are resin bonded to a heavy-duty cotton cloth. The
result is a cool aggressive rate of cut. Excellent for creating or restoring
line finishes, matching mill finishes and levelling small welds. These belts
are well suited as a starting point for further surface refinement.
