Maintenance; Protecting The Environment - Black & Decker LD108 Instruction Manual

18 • ENGLISH
f 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 (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.
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.
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:
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.
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
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 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, one hand on the
handle, and the other gripping the bottom around the
battery area.
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
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 lubricants that work best are sulfurized
cutting oil or lard oil.

MAINTENANCE

Keep guards, air vents and the motor housing as clear as
possible of dust and dirt. Wipe with a clean cloth and blow
through with a low-pressure air supply. Excessive build-up
of metal dust can cause tracking of electrical current from
the internal parts to exposed metal parts.
Important! To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment (other than those
listed in this manual) should be performed by authorized
service centers or other qualified service personnel,
always using identical replacement parts.
