INSTALLING THE AUXILIARY SIDE HANDLE
Install the auxiliary handle (1) for two- handed
operation of the drill (Fig. 9). This is particularly
important for hammer drilling in concrete.
NOTE: The auxiliary handle can be installed on
either the left or right side of the hammer drill.
1.
Turn the auxiliary handle (1) several turns
counter clockwise until the mounting collar
(2) will slide over the chuck onto collar
mount immediately behind the torque ring
(3).
2. Rotate the auxiliary handle & collar around
the drill body until it is in a comfortable
position. Turn the auxiliary handle
clockwise to tighten it into the drill housing.
NOTE: Tighten the auxiliary handle by
hand only. Do NOT over tighten the handle
or you will damage the handle or the
mounting collar.
INSTALLING THE DEPTH STOP ROD
The depth stop rod is used as a gauge to control
the depth of the drilled hole. The depth stop rod
can be used with the hammer drill in either the
normal drilling mode or in the hammer drill
mode.
1.
Turn the auxiliary handle (1) counter
clockwise about three turns to open the
depth stop rod mounting clamp (4)
(Fig. 10).
2. Insert hexagonal end of depth rod (4) into
the matching hole (5) in the depth stop rod
mounting clamp.
3. Position the depth stop rod so the tip of the
round end will contact the workpiece when
the drill reaches the appropriate depth.
4. When the depth stop rod is properly
positioned, tighten the depth stop rod
mounting clamp by turning the auxiliary
handle clockwise.
NOTE: Tighten the handle by hand only.
Do NOT over tighten or you will damage
the handle or the depth stop mounting
clamp.
