TO REMOVE
To remove the bit or accessory, turn the keyless
chuck counter-clockwise direction to loosen
the collet, and then get the bit out.
DUAL RANGE GEAR SELECTOR
The dual range gear selector allows you to
select the gear with the optimum speed and
torque to suit the application.
Use low speed for starting holes without a cen-
ter punch, driving screws and drilling ceramics,
or in applications requiring a higher torque.
High speed is better for drilling wood and
wood compositions, steel and for using abra-
sive and polishing accessories.
To select the low speed,
high torque setting, turn
the tool off and let the
motor come to a com-
plete standstill. Slide the
dual range gear selector
forward fully so that the
letter"LOW" is shown.
To select the high speed, low torque setting,
turn the tool off and let the motor come to
a complete standstill. Slide the dual range
gear selector backward fully so that the word
"HIGH" is shown.
NOTE: Make sure that the dual range gear se-
lector is either completely in position "LOW"
or "HIGH". Do not change gears when the
tool is running. If you have difficulty chang-
ing from one gear range to the other, turn the
chuck by hand until the gears engage.
FORWARD/REVERSE CONTROL
The forward/reverse control determines the di-
rection of rotation of the tool.
To select forward rota-
tion, release the trigger
switch and push the for-
ward/reverse control to
the left side of the tool.
To select reverse, push
the forward/reverse con-
trol to the right side of
the tool.
The center position of the control locks the
trigger in the off position
E N G L I S H •
WARNING: When changing the position of
the control, make sure the trigger is released
and the motor is stationary.
NOTE: The first time the tool is run after chang-
ing the direction of rotation, you may hear a
click on start up. This is normal and does not
indicate a problem.
TORQUE ADJUSTMENT COLLAR
Your drill is fitted with a variable clutch, which
is operated with the torque adjustment ring.
Once adjusted, the clutch will work at a pre-
determined torque; this avoids screwing too
deeply or damaging your drill. Torque adjust-
ment varies with the types of screw used and
the working material. Always start using a low
torque and increase gradually to achieve suit-
able operation. Select the desired operating
torque by turning the torque adjusting ring to
the appropriate setting.
FUNCTION SELECTOR
Three working modes are
available on this tool: drill-
ing, screwdriving and ham-
mer drilling. To select any
of the three modes, rotate
the function selection collar
until the desired symbol aligns with the indica-
tor on the housing.
SWITCHING ON AND OFF
Hold the tool firmly to control the twisting of
the tool.
To prolong the life of the tool never overload
it. Start the tool by squeezing the variable
speed trigger switch. Release the trigger to
stop the tool.
This tool has a variable speed switch that de-
livers higher speed and torque with increased
trigger pressure. Speed is controlled by the
amount of switch trigger depression.
The variable speed feature is particularly use-
ful when driving screws. It also enables you to
select the best speed for a particular applica-
tion.
NOTE: It is recommended to use the variable
speed feature for a short time only. Do not
continuously operate the tool at different
speeds. It may damage the switch.
