The air regulator knob can be used as an air throttle and can be used for
setting positive speed control. The air inlet used for connecting air supply has
standard 1/4" NPT thread.
Let the sander do the work. The normal weight of the machine is sufficient
for efficient sanding. Do not put additional pressure on the machine. This will
only slow down the speed of the pad, reduce sanding efficiency and put an
additional burden on the motor. Start the sander off the work, set it down on
the work evenly and move it slowly back and forth in wide, overlapping areas.
When finished sanding, lift it off the work before stopping the motor.
