!WARNING To prevent personal injury. Do not change the mode

selector switch while the sander is in operation.

Operating Mode 1

This operating mode is recommended for fast material removal on very rough, insensitive surfaces

as well as for buffing.

Operating Mode 2

This operatng mode is recommended for sensitive

surfaces as well as for fine polishing.

ELECTRONIC FEEDBACK

CIRCUITRy (EFC)

The internal electronic feedback system provides a "soft start", which will reduce the stresses that occur from a high torque start. The system also helps to keep the no load speed virtually constant between no-load and load conditions.

VARIABLE SPEED WITH DIAL SETTING Your sander is also equipped with a variable speed dial. The sander's orbital pad speed can be preset from zero to maximum nameplate OPM by rotating the dial in the housing. The dial may be set on or between any of six positions (1=low through 6=high).

The following table may be used as a general guide for abrasive and backing pad selection, but the best results will be obtained by sanding a test sample of the workpiece first.
