WARNING:
Always wear safety goggles or safety glasses with side
shields when operating hammer drill. Failure to do so
could result in dust, shavings, or loose particles being
thrown into your eyes, resulting in possible serious injury.
DRILLING
See Figure 11.
1. Depress and release the switch trigger to be sure your
drill is in OFF position before connecting it to power
supply.
2. Check the direction of rotation lever for correct setting
(forward or reverse).
See Figure 3, Page 6.
3. Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
4. Plug your hammer drill into power supply source.
5. Hold your drill firmly and place the bit at the point to be
drilled.
6. Depress the switch trigger to start your drill. Do not
lock the switch ON for jobs where your drill may need
to be stopped suddenly.
7. Move the drill bit into the workpiece applying only
enough pressure to keep the bit cutting. Do not force
your drill or apply side pressure to elongate a hole. Let
your drill and bit do the work.
See Figure 11.
WARNING:
Be prepared for binding or breakthrough. When these
situations occur, drill has a tendency to grab and kick in
the opposite direction and could cause loss of control
when breaking through material. If not prepared, this loss
of control can result in possible serious injury.
When drilling hard, smooth surfaces use a center punch to
mark the desired hole location. This will prevent the drill bit
from slipping off center as the hole is started. However, the
variable speed feature allows starting holes without center
punching if desired. To accomplish this, operate your drill at
a low speed until the hole is started.
When drilling metals use a light oil on the drill bit to keep it
from overheating. The oil will prolong the life of the bit and
increase the drilling action.
If the bit jams in the workpiece or if your drill stalls, stop the
tool immediately. Remove the bit from the workpiece and
determine the reason for jamming.
