Follow these steps to adjust the depth gauge rod.
■
Lock the trigger switch by placing the rotation selector
in the center position.

Loosen the auxiliary handle by turning the knob
counterclockwise.
■
Adjust the depth gauge rod so that the drill bit
extends beyond the end of the rod to the required
drilling depth.
■
Tighten the auxiliary handle by turning the knob
clockwise.
ADJUSTING THE TORQUE (Fig. 5)
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
hammering. Failure to obey this caution may
result in property damage.
SWITCH (Fig. 6)
■
To turn your drill ON, depress the switch trigger.
■
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 (Fig. 6)
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 (Fig. 6)
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.
OPERATION
ADJUSTING THE SPEED (Fig. 8)
Follow these steps to adjust the speed.
■
For high speed: Slide the two-speed gear train switch
to “2.”
■
For low speed: Slide the two-speed gear train switch
to "1."
Note: If you have difficulty 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.
KEYLESS CHUCK (Fig. 7)
Your drill has a keyless chuck. As the name implies,
you can hand tighten or release dr ill 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 direction 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.
