RECOMMENDED MAINTENANCE PROCEDURES
ROUTINE INSPECTION
It is recommended that you periodically inspect your
DELTA
®
Dual Drum Sander as a precautionary action.
During this time, check all hardware such as bolts,
nuts and screws to ensure they are properly tightened.
Also verify that the sanding belts and drive belts are
mounted properly and have not become loose or torn.
Also take this opportunity to inspect for dust and/or
wood particles that may have accumulated on or in the
machine.
LUBRICATION
The table height adjustment screw shafts, located at
either end of the machine must be well lubricated with
grease at all times. In order to access, inspect and
lubricate the screw shafts, it is necessary to remove
the two side guards located on either end of the
machine.
To remove the side guards:
1. Remove the elevation cursor by unscrewing the
retaining screw.
2. Remove the eight Phillips head bolts and washers
securing the left and right side guards to the
machine and remove the guards. See Fig. 14.
3. Re-attach side guards and elevation cursor.
CLEANING THE SANDING BELTS
Regularly clean the sanding belts on the drums with
commercially available cleaning sticks, following the
manufacturer’s directions. When cleaning, also brush
the stick crumbs from the sanding drum while it is still
rotating.
