ADDITIONAL HANDLE AND DEPTH GAUGE
CAUTION: Make sure that the power tool is
OFF and unplugged before making any adjust-
ment. Turn the auxiliary handle counter clock-
wise to loosen the collar and allow the depth
gauge passes over the chuck, set the proper
position for the work to be performed.
Set the depth gauge if required and adjust the
handle to secure in its place.
The side handle can be
rotated 360 degrees
to find a position that
offers better comfort
and eases the opera-
tion. The depth gauge
helps to set the correct
depth if you need to
measure a drilled hole.
To change the position of depth gauge, turn the
handle clockwise until the depth gauge is loose
enough to slide through the hole. Set the depth,
check it with a metal rule for a more accurate
measurement, and then readjust the grip of
the handle to set the depth guide into position.
