Wrapping Abrasive Strips
WRAPPING ABRASIVE STRIPS:
Note:
When using pre-Marked™ OR Pre-Cut™ abrasives, not all the steps below are necessary.
Proper attachment of the abrasive strip to the drum is critical to achieving top performance from your Supermax
Tools 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 drum, and the second taper is
made for attachment to the right (inboard) side of the drum. To attach a strip to the drum, follow the procedure
below.
1.) Mark and cut a taper at one end of the roll as shown in Figure 12a.) Because the tapered end should use most
of the left (outboard) slot width, its end must be trimmed (Figure’s 12-b and 12-c) . Raise the clip lever on the left
(outboard) side of the drum (Figure 12-d) . Insert the tapered end through the slot and into the fastener so that it
uses most of the width of the slot. Release the clip lever to securely hold the strip end in the fastener.
2.) Wrap the strip around the drum, being careful not to overlap the windings. The tapered cut of the strip end
should follow the edge of the drum. Continue to wrap the abrasive in a spiral fashion by rotating the drum with your
left hand and guiding the strip with your right hand
(Figure 12-e) . Successive windings of the strip should be flush
with previous windings without any overlap.
