increases or reduces the speed by 1,200rpm until it reaches the limits.The
rpm can be adjusted in the range 4,000 to 10,000 rpm.

can be adjusted linearly by changing the position of the lever.In the other
mode the speed remains fixed at the set max rpm when the tool is
running.When the rpm+and rpm-buttons are pressed simultaneously the
tool toggles between the two controlling modes.

the tool.Always remove the tool from the work surface before stopping
