Follow these directions to turn the hammer drill on and
off.
■

LOCKING ON
See Figure 10.
The lock-on feature allows you to lock the drill on when
you operate it continuously for extended periods of time.
If you have the “lock-on” feature engaged during use and
the drill is disconnected from the power supply, disengage
the “lock-on” feature immediately. Also, do not lock the
trigger switch if you might need to suddenly stop the drill.
WARNING:
Before connecting the hammer drill to a power sup-
ply, make sure it is not in the “locked-on” position.
Failure to do so could result in accidental starting of
the drill resulting in possible serious injury.
Follow these directions to lock on.
■ Depress the switch trigger.
■ Push in the lock-on button.
■ Release the switch trigger.
■ Release the lock-on button.
NOTE: To release the lock, depress the switch trigger.
DRILLING
See Figure 11.
Follow these directions to drill.
■ Depress and release the switch trigger to make sure
the drill is in the OFF position before connecting it to
a power supply.
■ Check the rotation lever for the correct setting. Re-
fer to “CHANGING THE ROTATION” earlier in this
manual.
■ Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.
■ Plug the hammer drill into a power supply.
■ Hold the drill firmly and place the bit at the point to
be drilled.
■ Depress the switch trigger to start the drill.
■ Move the drill bit into the workpiece applying only
enough pressure to keep the bit cutting.
NOTE: Do not force the drill or apply side pressure
to elongate a hole. Let your drill and bit do the work.
WARNING:
Be prepared for binding or 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 pos-
sible serious injury.
