CHANGING THE DISC
Before changing the abrasive disc:
1. Make sure the power to the sander is turned
OFF
at the source yellow lock insert is removed
from the start/stop switch.
2. Lower the working table to the lowest position.
3. Tilt back the guard to expose the top of the disc.
The sander takes standard 20” (508mm)
diameter cloth or paper back discs. A good recommendation would be 60 grit for coarse or
rough sanding, 80 grit for general purpose medium duty sanding, and 100 grit for fine
sanding.
4. Pull at the edge of the mounted grinding disc to get it started, then pull it completely off of the
drive disc.
5. Make sure the drive disc surface is clean. Use a putty knife to remove the old abrasive or if
necessary, use a cleaner which dries film-free such as naphtha to remove any old adhesive
(or dust) which might adhere to the drive disc.
6. Remove about 1/3 of the protective cover from the back side of the new grinding disc.
7. Put the exposed edge of the new grinding disc against the drive disc and center the grinding
disc carefully onto the drive disc. Press to hold that section against the drive disc.
8. Rotate the drive disc 180°. The part of the grinding disc which is attached to the drive disc
will now be at the bottom of the drive disc, and will be slightly hidden behind the table. With
the drive disc in this position, you can keep the grinding disc accurately centered while
reaching between the grinding disc to remove the rest of the protective backing. Securely
press the rest of the grinding disc against the face of the drive disc.
9. Move the wheel guard forward so it covers the edge of the grinding and drive disc.
10. Adjust the table to working height.
11. Reconnect power to the machine.
12. Turn the machine "
ON
" and observe the action of the disc for possible unbalance. When you
are sure that everything is operating correctly, you can resume sanding / grinding operations.
CAUTION:
Avoid material catching and being thrown from the machine.
The gap between the abrasive surface and the table edge must not exceed 3/16"
(4.75mm). If it does, loosen the four motor mount bolts and move the motor forward
to minimize the gap.
