OPERATION
ADJUSTING THE TORQUE
See Figure 3.
The tool is equipped with an adjustable torque clutch for
driving different types of screws into different materials.
Adjust the torque as necessary.
We recommend that you use carbide-tipped bits and select
impact mode when drilling in hard material such as brick,
tile, concrete, etc.
CAUTION
The impact drill is not designed for reverse ham-
mering. Failure to obey this caution may result in
property damage.
SWITCH
See Figure 4.
n To turn your drill ON, depress the switch trigger.
n To turn it OFF, release the switch trigger.
VARIABLE SPEED
This tool has a variable speed switch that delivers higher
speed and torque with increased trigger pressure. Speed is
controlled by the amount of switch trigger depression.
SWITCH LOCK
See Figure 4.
The switch trigger can be locked in the OFF position. This
feature can be used to prevent the possibility of accidental
starting when not in use. To lock switch trigger, place the
direction of rotation selector (Forward/Reverse Selector)
in center position.
NOTE: When selector is in center position, switch trigger
is locked.
REVERSIBLE
See Figure 4.
This tool has the feature of being reversible. The direction of
rotation is controlled by a selector located above the switch
trigger. With the drill held in normal operating position, the
direction of rotation selector should be positioned to the left
of the switch for drilling. The drilling direction is reversed
when the selector is to the right of the switch. When the
selector is in center position, the switch trigger is locked.
To stop, release switch trigger and allow the chuck to come
to a complete stop.
ELECTRIC BRAKE
This drill has an electric brake. When the trigger switch
is released, the chuck stops turning. When the brake is
functioning properly, sparks will be visible through the vent
slots on the housing. This is normal and is the action of
the brake.
KEYLESS CHUCK
See Figure 5.
Your drill has a keyless chuck. As the name implies, you can
hand tighten or release drill bits in the chuck jaws. Rotate
the chuck with your hand. Rotate the chuck body with your
other hand. The arrows on the chuck indicate which direc-
tion to rotate the chuck body in order to LOCK (tighten) or
UNLOCK (release) the drill bit.
WARNING
Do not hold chuck body with one hand and use
power of the drill to tighten chuck jaws on drill bit.
Chuck body could slip in your hand or your hand
could slip and come in contact with rotating drill bit.
This could cause an accident resulting in serious
personal injury.
ADJUSTING THE SPEED
See Figure 6.
Follow these steps to adjust the speed.
n For high speed: Slide the two-speed gear train switch
to “2.”
n For low speed: Slide the two-speed gear train switch
to “1.”
NOTE: If you have diffi culty changing from one gear
range to the other, turn the chuck by hand until the
gears engage.
CAUTION
To prevent gear damage, always allow chuck to
come to a complete stop before changing the
speed or the direction of rotation.
MAINTENANCE
WARNING
When servicing, use only identical replacement
parts. Use of any other part may create a hazard
or cause product damage.
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
