OPERATING INSTRUCTIONS
WARNING:

making any adjustments or removing/
installing attachments or accessories.
TRIGGER SWITCH & REVERSING
BUTTON
• The drill is turned ON and OFF by
pulling and releasing the trigger switch
(1). The farther the trigger is depressed,
the higher the speed of the drill.
• A forward/reverse control button (2)
determines the direction of the tool and
also serves as a lock off button.
• To select forward rotation, release the
trigger switch and depress the forward/
reverse control button to the left.
• To select reverse, depress the forward/
reverse control button the opposite direction.
NOTE: The center position of the control
button locks the tool in the off position.
When changing the position of the control
button, be sure the trigger is released.
TORQUE CONTROL (FIGURE 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 in wood, metal and plastics,
set the collar to the drilling position
symbol
• For screwdriving, set the collar to the
desired setting. If you do not yet know the
appropriate setting, proceed as follows:
• Set the collar to the lowest torque setting.
• Tighten the first screw.
• If the clutch ratchets before the desired
result is achieved, increase the collar
setting and continue tightening the screw.
Repeat until you reach the correct setting.
Use this setting for the remaining screws.
