CAUTION:

•

After adjusting the depth of cut, always tighten the
lever securely.

Loosen the lever on the side of the rear handle and
move the base up or down. At the desired depth of cut,
secure the base by tightening the lever.
For cleaner, safer cuts, set cut depth so that no more
than one blade tooth projects below workpiece. Using
proper cut depth helps to reduce potential for dangerous
KICKBACKS which can cause personal injury.
