Hole Drilling; Drilling Wood - F.F. Group CDD-BL 20V PRO Notice Originale

First gear allows slower
drilling with more
torque,while second
gear is suitable when
less torque but higher
speed is required.
Slide the selector
forward to select first
gear.
Slide the selector
backward to select
second gear.
FORWARD/REVERSE SWITCH (2)
/ Shown on the forward/reverse lever
Set the Left/right switch to
1.
Change the direction of rotation only when the
2.
machine is not in operation!
VARIABLE SPEED
To start drilling squeeze the variable speed trigger.
To stop drilling release the trigger.
Note: The more the trigger is depressed, the fast-
er the drilling bit will rotate.
Caution: Operating the machine with a low speed
for a long time will increase the risk that the motor
will be overheated. To prevent overheating, let the
motor cool down regularly (Stop using the machine
for 15 minutes).
TORQUE SETTING (4a)
Rotate the torque setting ring to the desired setting.
The torque setting will help you regulate the driving
power when using a screwdriver bit. This will help to
prevent damage to the workpiece and/or screw.
Note: selecting a higher torque setting will allow
the drill to use more torque to drive the screw in
or out. To prevent damaging the screw head, it is
recommended to start at a low torque setting and
increase when necessary.
LED WORKLIGHT (6)
The tool has an LED light to illuminate the work area
and improve vision when working in areas with insuf-
ficient light. The LED light will switch on automatically
while the trigger switch is depressed.
SCREW DRIVING (41316-41317)
Set the torque collar to lowest setting and tighten the
first screw. If the clutch ratchets and makes a clicking
sound before screw is flush, increase the torque set-
ting and continue tightening. Repeat until you reach
the correct setting/screw depth. Use this setting for
remaining screws.
Install the correct driver bit.
ƒ
Ensure that the torque adjustment collar is set to
ƒ
the most suitable setting, if in doubt start with a low
setting and gradually increase the setting until the
most suitable position is found.
Use the correct speed for the job, apply minimal
ƒ
pressure to the trigger initially.
Only increase the speed when full control can be
ƒ
maintained.
It is advisable to drill a pilot hole first, slightly lon-
ƒ
ger and just smaller than the shank diameter of the
screw to be fitted.
The pilot hole will act as a guide for the screw and
ƒ
will also make tightening of the screw less difficult.
When screws are positioned close to an edge of the
ƒ
material, a pilot hole will also help to prevent split-
ting of the wood.
Use the correct countersinking bit to accommodate
ƒ
the screw head so that it does not protrude.
If the screw becomes difficult to drive in, remove
ƒ
and try a slightly larger or longer hole but remem-
ber there must be enough material for the screw to
grip! If restarting a screw in a hole, locate and make
the first few turns by hand. If the screw is still dif-
ficult (as when using very hard woods) try using a
lubricant such as soap; liquid soap is usually best.
or Keep sufficient pressures on the drill to prevent the
ƒ
bit turning out of the screw head. The screw head
can easily become damaged making it difficult to
drive it in or even remove it.
TORQUE SELECTION CONTROL (41317)
By turning the collar (4b) it is possible to switch be-
tween rotary drilling, percussion drilling and screw-
driving functions. Set the "twist drill" setting
tary drilling/screwdriving, in the "hammer drill" setting
, the percussion feature will come into action. This
is intended for drilling into masonry, etc. Turn the collar
to the
DRILLING (41316)
Turn the collar (4a) to the "twist drill" setting
for rotary drilling/screwdriving

HOLE DRILLING (41316-41317)

When attempting to drill a large diameter hole, it is
ƒ
sometimes best to start with a smaller drill bit then
work up to the required size.
This prevents overloading the drill.
ƒ
WARNING! Many accidents occur because of un-
ƒ
foreseeable situations. Please pay attention that
drilling-out a small hole may cause the drill bit to jam
in the hole.
Remember to use a "wood-pecker" action on deep
ƒ
holes to allow the swarf to be ejected from the hole.
If the drill bit snags, switch off immediately to pre-
ƒ
vent permanent damage to the drill.
Try running the drill in reverse to remove the bit.
ƒ
Keep the drill in line with the hole. Ideally, the drill bit
ƒ
should enter at right angles to the work. If the angle
is changed during drilling, this could cause the bit to
snap off blocking the hole and perhaps causing injury.
Reduce pressure as the drill is about to break through
ƒ
the item being drilled.
Don't force the drill, let it work at its own pace.
ƒ
Keep the drill bit sharp.

DRILLING WOOD (41316-41317)

For maximum performance when drilling larger
ƒ
holes, use auger bits or spade bits for wood drilling.
Set the tool to the drill mode.
ƒ
Begin drilling at a very low speed to prevent the bit
ƒ
from slipping off the starting point. Increase the
speed as it bites into the wood.
When drilling through holes, place a block of wood
ƒ
behind the work piece to prevent ragged or splin-
setting to use the drill for screwdriving.
