OPERATION
USING DEPTH GAGE ROD
See Figure 6.
A depth gage rod has been installed on your hammer drill to
assist you in controlling the depth of drilled holes.
■ Adjust depth gage rod so that the drill bit extends beyond
the end of the rod to the required drilling depth.
■ Securely tighten auxiliary handle. This secures depth
gage rod at desired depth of cut. It also secures auxiliary
handle assembly.
When drilling holes with the depth gage rod installed, the
desired hole depth has been reached when the end of the rod
comes in contact with the surface of the material being
drilled.
TO ADJUST DRILLING MODE
See Figure 7.
To adjust for type of drilling, slide mode selector on top of
motor housing left to hammer mode or right to drilling mode.
For your convenience a hammer symbol and drill bit symbol
have been molded into motor housing.
CAUTION:
Your hammer drill has not been designed for reverse
hammering. Failure to obey this warning may result in
property damage.
We recommend that you use carbide-tipped bits and select
hammer mode when drilling in hard materials such as brick,
tile, concrete, etc.
We recommend that you select normal drill mode when
drilling with twist drills, hole saws, etc. in soft materials.
