Warning! Drill may stall (if overloaded or improperly
used) causing a twist. Always expect the stall. Grip the drill
firmly with both hands to control the twisting action and
prevent loss of control which could cause personal injury.
If a stall does occur, release the trigger immediately and
determine the reason for the stall before re-starting.
Warning! Let the tool work at its own pace. Do not
overload.
Warning! Before drilling into walls, floors or ceilings,
check for the location of wiring and pipes.
Fitting and removing a drill bit or screwdriver bit
The drill/screwdriver attachment (11) is fitted with a
keyless chuck (12) to allow for an easy exchange of bits.
f Lock the tool by setting the forward/reverse slider (4)
to the center position.
f Open the chuck by turning the front part clockwise
with one hand while holding the rear part with the other.
f Insert the bit shaft into the chuck.
f Firmly tighten the chuck by turning the front part
counterclockwise.
f To remove the screwdriver bit from the holder, lift the
bit from the recess.
f To store the screwdriver bit, firmly push it into the
holder (7).
Screwdriving
f Always use the correct type and size of screwdriver bit.
f If screws are difficult to tighten, try applying a small
amount of washing liquid or soap as a lubricant.
f Always hold the tool and screwdriver bit in a straight
line with the screw.
f 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.
Keyless chuck (Fig. F)
Warning! To reduce the risk of injury, turn off
and remove battery from the tool before making any
adjustments or removing or installing attachments or
accessories.
Warning! Do not attempt to tighten or loosen 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.
To insert a drill bit or other accessory:
1. Grasp the rear half of the chuck (9) with one hand
and use your other hand to rotate the front half 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.
Torque control (Fig. G)
This tool is fitted with a torque adjustment collar (10)
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.
f For drilling in wood, metal and plastics, set the collar
to the drilling position symbol
f For screwdriving, set the collar to the desired setting.
If you do not yet know the appropriate setting, proceed
as follows:
f Set the collar to the lowest torque setting.
f Tighten the first screw.
f 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.
On-board bit storage
A bit storage slot (10) is built-in to the area just above the
battery pack for easy bit storage and access.
Drilling
f Use sharp drill bits only.
f Support and secure work properly, as instructed in the
Safety Instructions.
f Use appropriate and required safety equipment, as
instructed in the Safety Instructions.
f Secure and maintain work area, as instructed in the
Safety Instructions.
f Run the drill very slowly, using light pressure, until the
hole is started enough to keep the drill bit from slipping
out of it.
f 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.
f Hold the drill firmly with two hands to control its
twisting action.
f Do not click the trigger of a stalled drill off and on in an
attempt to start it. Damage to the drill can result.
f Minimize stalling on breakthrough by reducing pressure
and slowly drilling through the last part of the hole.
f Keep the motor running while pulling the bit out of a
drilled hole. This will help reduce jamming.
f Make sure switch turns drill on and off.
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
