A forward/reverse control button (2) determines the direc-
u
tion of the tool and also serves as a lock off button.
To select forward rotation, release the trigger switch and
u
depress the forward/reverse control button to the left.
To select reverse, depress the forward/ reverse control
u
button the opposite direction.
To lock the tool, set the forward/reverse slider into the
u
centre position.

in the off position. When changing the position of the control
button, be sure the trigger is released.
Torque control (fig. D)
This tool is fitted with a torque adjustment collar (3) to select
the operating mode and to set the torque for tightening
screws. Large screws and hard workpiece materials require
a higher torque setting than small screws and soft workpiece
materials.
For drilling, set the collar to the drilling position symbol
u
For screwdriving, set the collar to the desired setting. If
u
you do not yet know the appropriate setting, proceed as
follows:
Set the collar to the lowest torque setting.
u
Tighten the first screw.
u
If the clutch ratchets before the desired result is
u
achieved, increase the collar setting and continue
tightening the screw. Repeat until you reach the correct
setting. Use this setting for the remaining screws.
Keyless chuck (fig. E)
Warning! Make certain the lock-off button is engaged to
prevent switch actuation before installing or removing
accessories.
To insert a drill bit or other accessory:
Grasp the rear half of the chuck (8) with one hand and
u
use your other hand to rotate the front half (9) in the
counterclockwise direction, as viewed from the chuck end.
Insert the bit or other accessory fully into the chuck, and
u
tighten securely by holding the rear half of the chuck and
rotating the front portion in the clockwise direction as
viewed from the chuck end.
Warning! Do not attempt to tighten drill bits (or any other
accessory) by gripping the front part of the chuck and turning
the tool on. Damage to the chuck and personal injury may
occur when changing accessories.

Hints for optimum use
Drilling
Use sharp drill bits only.
u
b
Support and secure work properly, as instructed in the
u
Safety instructions.
Use appropriate and required safety equipment, as
u
instructed in the Safety instructions.
Secure and maintain work area, as instructed in the Safety
u
instructions.
Run the drill very slowly, using light pressure, until the hole
u
is started enough to keep the drill bit from slipping out of it.
Apply pressure in a straight line with the bit. Use enough
u
pressure to keep the bit biting but not so much as to stall
the motor or deflect the bit.
Hold the drill firmly with two hands to control its twisting
u
action.
DO NOT CLICK THE TRIGGER OF A STALLED DRILL
u
OFF AND ON IN AN ATTEMPT TO START IT. DAMAGE
TO THE DRILL CAN RESULT
Minimize stalling on breakthrough by reducing pressure
u
and slowly drilling through the last part of the hole.
Keep the motor running while pulling the bit out of a drilled
u
hole. This will help reduce jamming.
Make sure switch turns drill on and off.
u
Drilling in wood
Holes in wood can be made with the same twist drill bits used
for metal or with spade bits. These bits should be sharp and
should be pulled out frequently when drilling to clear chips
from the flutes.
Drilling in metal
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. The cutting
lubricant that work best are sulfurized cutting oil or lard oil
Drilling in masonry
For drilling in masonry, set the collar (3) to the hammer drilling
position by aligning the symbol with the marking.
