Adjusting 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
u
the drilling position symbol.
For screwdriving, set the collar to the desired setting.
u
If 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.
u
Use this setting for the remaining screws.
u
Dual range switch - figure E
The dual range feature of your drill allows you to shift gears
for greater versatility.
To select low speed, high torque setting (position1),
u
turn tool off and permit to stop. Slide gear shifter button (4)
away from the chuck.
To select the high speed, low torque setting (position
u
2), turn tool off and permit to stop. Slide gear shifter but-
ton back toward the chuck.
Note: Do not change gears when tool is running. If you are
having trouble changing gears, make sure that the dual range
gear button is either completely pushed forward or completely
pushed back.
keyless chuck - figure F
Warning! Make certain the battery pack is removed to prevent
tool actuation before installing or removing accessories.
To insert a drill bit or other accessory:
Grasp the chuck (5) and rotate it in the counterclockwise
u
direction, as viewed from the chuck end.
Insert the bit or other accessory fully into the chuck, and
u
tighten securely by rotating the chuck in the clockwise
direction as viewed from the chuck end.
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.
Hammer Action
The BL188 drill has hammer action which is engaged by
twisting the collar to the hammer symbol
hammer action when drilling in masonry.
Warning! When the torque adjustment collar is in the drill or
hammer drill positions, the drill will not clutch.

(Original instructions)
q
. Use
The drill may stall if overloaded, causing a sudden twist.
Screw driving
For driving fasteners, the forward/reverse button should
u
be pushed to the left.
Use reverse (button pushed to the right) for removing
u
fasteners.
Note: When moving from forward to reverse, or vice versa,
always release the trigger switch first.
Drilling
Use sharp drill bits only.
u
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
u
Safety Instructions.
Run the drill very slowly, using light pressure, until the
u
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
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, one hand on the han-
u
dle, and the other gripping the bottom around the battery
area or the auxiliary handle if provided.
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
lubricants that work best are sulphurized cutting oil.
Drilling in masonry
Shift drill into 'Hammer mode'. Use carbide tipped masonry
bits. Refer to drolling section. Keep even force on the drill but
not so much that crack the brittle material. A smooth, even
flow of dust indicates the proper drilling rate.
