Speed adjusting dial
For 9911 only
► Fig.2: 1. Speed adjusting dial
The belt speed can be infinitely adjusted between 75 m
and 270 m per minute 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:
• If the tool is operated continuously at low
speeds for a long time, the motor will get over-
loaded, resulting in tool malfunction.
• 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.

ing to the insides which might hamper further collection.
