LUBRICATION

CAUTION: Disconnect sander from power

source before performing maintenance.
Do not operate the sander until it is properly lubri-
cated.
All ball bearings are sealed for life and do not require
lubrication.
Apply a drop of light machine oil occasionally on the
hinge of the tension mechanisms as shown in Fig-					FIGURE 10
ure 10. Service the machine every 6 weeks.
SANDING BELT SELECTION
Use the chart, Figure 11, for selecting an abrasive
belt. Aluminum oxide is recommended for general
use in the home workshop.
Figure 12 groups abrasives into five classes, indi-
cating the grit numbers that fall into each.
