OPERATION
USING THE LEVELS
See Figure 13.
Two levels are recessed in the motor housing of the hammer
drill. One is located on top, while the other is located on the
end. They can be used to keep drill bits level during both
horizontal and vertical drilling operations.
DRILLING
See Figure 13.
n
Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
n Hold the tool firmly and place the bit at the point to be
drilled.
n Depress the trigger switch to start the tool.
n Move the drill bit into the workpiece, applying only
enough pressure to keep the bit cutting. Do not force
or apply side pressure to elongate a hole.
WARNING:
Be prepared for binding at breakthrough. When these
situations occur, the drill has a tendency to grab and
kick in the opposite direction and could cause loss of
control when breaking through material. If you are not
prepared, this loss of control could result in possible
serious injury.
HELPFUL TIPS
n
When drilling hard, smooth surfaces, use a center punch
to mark the desired hole location. This prevents the drill
bit from slipping off center as you start the hole. You may,
however, start holes without center punching if you use
the lower speed. To accomplish this action, simply oper-
ate the drill at a lower speed until the hole is started.
n When drilling metals, use a light oil on the drill to keep
it from overheating. The oil will prolong the life of the bit
and increase the drilling action.
n If the bit jams in the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
WARNING:
Do not force the tool. Forcing the tool can result in jam-
ming and loss of balance or footing, which could result
in personal injury.
