rate. Proceed as follows:
u
Re-insert the battery (7).
u
If the charging indicators continues flashing red
at a fast rate, use a different battery to deter-
mine if the charging process works properly.
u
If the replaced battery charges correctly, the
original battery is defective and should be
returned to a service centre for recycling.
u
If the new battery gives the same indication
as the original battery, take the charger to be
tested at an authorised services centre.
Note: It may take as long as 60 minutes to
determine that the battery is defective. If the
battery is too hot or too cold, the LED will
alternately blink red, fast and slow, one flash at
each speed and repeat.
Selecting the direction of rotation (fig. C)
For drilling and for tightening screws, use forward
(clockwise) rotation. For loosening screws or
removing a jammed drill bit, use reverse (counter-
clockwise) rotation.
u
To select forward rotation, push the forward/
reverse slider (2) to the left.
u
To select reverse rotation, push the forward/
reverse slider to the right.
u
To lock the tool, set the forward/reverse slider
into the centre position.
Selecting the operating mode or torque
(fig. D)
This tool is fitted with a collar to select the
operating mode and to set the torque for tighten-
ing screws. Large screws and hard workpiece
materials require a higher torque setting than small
screws and soft workpiece materials. The collar
has a wide range of settings to suit your applica-
tion.
u
For drilling in wood, metal and plastics, set the
collar (3) to the drilling position by aligning the
symbol
b
with the marking (14).
u
For screwdriving, set the collar to the desired
setting. If you do not yet know the appropriate
setting, proceed as follows:
- Set the collar (3) 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.
Drilling in masonry (fig. D & E)
u
For drilling in masonry, set the collar (3) to the
hammer drilling position by aligning the symbol
q
with the marking (14).
u
Slide the speed selector (5) towards the front of
the tool (2nd gear).
Speed selector (fig. E)
u
For drilling in steel and for screwdriving applica-
tions, slide the speed selector (5) towards the
rear of the tool (1st gear).
u
For drilling in materials other than steel, slide the
speed selector (5) towards the front of the tool
(2nd gear).
Drilling/screwdriving
u
Select forward or reverse rotation using the
forward/reverse slider (2).
u
To switch the tool on, press the switch (1). The
tool speed depends on how far you press the
switch.
u
To switch the tool off, release the switch.
LED work light
The LED work light (8) is activated automatically
when the trigger is depressed. The LED work light
will illuminate when the trigger is partially de-
pressed, before the unit begins running.
State of charge indicator
The tool is fitted with a state of charge indicator.
This can be used to display the current level of
charge in the battery during use.
u
Press the state of charge indicator button (9).
Hints for optimum use
Drilling
u
Always apply a light pressure in a straight line
with the drill bit.
u
Just before the drill tip breaks through the other
side of the workpiece, decrease pressure on
the tool.
u
Use a block of wood to back up workpieces that
may splinter.
u
Use spade bits when drilling large diameter
holes in wood.
u
Use HSS drill bits when drilling in metal.
u
Use masonry bits when drilling in soft masonry.
u
Use a lubricant when drilling metals other than
cast iron and brass.
u
Make an indentation using a centre punch at
