OPERATION
The torque clutch can be adjusted to any of
24 different settings. The higher the torque
setting, the more force the hammer drill
produces to turn an object in either low or
high rotation speed.
When using the hammer drill for different
driving applications, increase or decrease
the torque in order to help prevent damage
to screw heads, threads, workpiece, etc.
Adjust the torque by rotating the torque-
adjustment ring. The proper setting depends
on the job and the type of bit, fastener, and
material you will be using.
In general, use greater torque for larger
screws. If the torque is too high, the screws
may be damaged or broken. For delicate
operations, such as removing a partially
stripped screw, use a low torque setting. For
operations such as drilling into hardwood,
use a higher torque setting.
NOTICE: Do not change the torque setting
when the tool is running.
MODE SELECTION (FIG. 11)
FIG. 11
Your tool has three operating modes: drilling
with hammering action, drilling only, and
driving screws. To set the operating mode,
rotate the mode-selector ring and torque-
adjustment ring to the desired settings.
KEYLESS CHUCK (FIG.9)
FIG. 9
Lock (Tighten)
The hammer drill has a keyless chuck to
tighten or release bits in the chuck jaws. The
arrows on the chuck indicate the direction in
which to rotate the chuck in order to LOCK
(tighten) or UNLOCK (release) the chuck
jaws on the bit.
WARNING:
Do not hold the chuck
with one hand and use the power of the
hammer drill to tighten the chuck jaws on
the drill bit. The chuck could slip in your
hand, or your hand could slip and come
in contact with the rotating bit. This could
cause an accident resulting in serious
personal injury.
