while a Wide Drum Sander is limited to its abrasive material for stock removal.
SANDING
1. With power off, rest stock on the feed table and advance the stock to a point so that
you can adjust height of sanding drum to equal thickness of stock at its greatest
point.
2. Connect and turn on dust collection equipment.
3. Adjust feed rate to match sanding requirements and width of stock.
4. Turn on unit and rest stock on the feed conceyor table allowing the fee bekt to carry
the stock into and engage the sanding action of the drum. Support long stock as
necessary during the feed operation. Once the sanding operation feed allows,
reposition yourself to the outfeed side of the machine to accept, support, and control
the board as it exits the Wide Drum Sander.
NOTE: Do not apply upward or downward pressure when supporting and guiding stock
through the sander. To do so may induce snipe (sander drum dig-in) into the sanded
stock.
5. Reverse the feed direction of the stock on successive passes, while adjusting the
depth of cut using the height adjustment handle assembly (refer to Figure2). Several
variables affect the proper depth of cut selected. They are: abrasive grit choice, width
of stock, hardness of stock, feed rate and moisture content of stock.
INSTALLING NEW REPLACEMENT ABRASIVE STRIPS
WARNING: To prevent possible serious personal injury, always disconnect the Wide
Drum Sander from the power source before serving the unit or changing the abrasive
strips.
Abrasive strips are available from local dealer in precut strips which require no special
measuing or trimming before installation. The abrasive strips are tapered at the ends to
be wrapped radially around the drum to provide a continuous sanding surface. You may
cut your own strips from bulk stock using the included abrasive strip as a pattern for
cutting your new replacenent strip.
1. Make sure the power swotch is off and disconnect the power cord from the outlet.
2. Using either a precut strip or one which you have cut for use, you begin the abrasive
installation by inserting the tip of the tapered strip into the slot in the left side of the
drum while depressing the clip (Figure13). Approximately one inch of material should
be inserted into the slot to make the connection in the abrasive clip. Release clip
pressure once the inserted tapered end is securely loaded in the clip jaws.
