TORQUE CONTROL (FIGURE C)
This toolisfitted witha torque a djustment 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.
KEYLESS CHUCK (FIGURE D)
zLWARNING:
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:
1. Grasp the rear half of the chuck (4) with
one hand and use your other hand to
rotate the front half (4a) in the
counterclockwise direction, as viewed
from the chuck end.
2. Insert the bit or other accessory fully into
the chuck, and 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.
z_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.
SCREW DRIVING
For driving fasteners, the reversing button should be pushed to the left. Use reverse
(button pushed to the right) for removing fasteners. When moving from forward to reverse,
or vice versa, always release the trigger switch first.
ON BOARD BIT STORAGE
A bit storage slot (6) is built-in to the area just above the battery pack.
DRILLING
• Use sharp drill bits only.
• Support and secure work properly, as instructed in the Safety Instructions.
• Use appropriate and required safety equipment, as instructed in the Safety Instructions.
• Secure and maintain work area, as instructed in the Safety Instructions.
• Run the drill very slowly, using light pressure, until the hole is started enough to keep the
drill bit from slipping out of it.
• Apply pressure in a straight line with the bit. Use enough 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, one hand on the handle, and the other
gripping the bottom around the battery area.
• DO NOT CLICK THE TRIGGER OF A STALLED DRILL OFF AND ON IN AN ATTEMPT
TO START IT. DAMAGE TO THE DRILL CAN RESULT.
• Minimize stalling on breakthrough by reducing pressure and slowly drilling through the
last part of the hole.
• Keep the motor running while pulling the bit out of a drilled hole. This will help reduce jamming.
• Make sure switch turns drill on and off.
