Speed adjusting dial
The belt speed can be infinitely adjusted between 3.3 m
(656 ft./min.) and 16.6 m (3,280 ft./min.) per second by
turning the speed adjusting dial to a given number setting
from 1 to 6.
Higher speed is obtained when the dial is turned in the
direction of number 6, lower speed is obtained when it is
turned in the direction of number 1. Select the proper
speed for the workpiece to be sanded.
CAUTION:
• The speed adjusting dial can be turned only as far
as 6 and back to 1. Do not force it past 6 or 1, or the
speed adjusting function may no longer work.
