f To lock the tool, set the forward/reverse slider into the
centre position.
Selecting the operating mode or torque (Fig. H)
This tool is fitted with a collar 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.
The collar has a wide range of settings to suit your
application.
f For drilling in wood, metal and plastics, set the collar
(3) to the drilling position by aligning the symbol with
the marking (17).
f For drilling in masonry, set the collar (3) to the
hammer drilling position by aligning the symbol with
the marking (17).
f For screwdriving, set the collar to the desired setting.
If you do not yet know the appropriatesetting, proceed
as follows:
f Set the collar (3) 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.
f Use this setting for the remaining screws.
Two-gear selector (Fig. H)
f For drilling in steel and for screwdriving applications,
slide the two-gear selector (5) towards the front of the
tool (1st gear).
f For drilling in materials other than steel, slide the two-
gear selector (5) towards the rear of the tool (2nd gear).
Drilling/screwdriving (Fig. A)
Select forward or reverse rotation using the forward/
reverse slider (2).
f To switch the tool on, press the switch (1). The tool
speed depends on how far you press the switch.
f To switch the tool off, release the switch.

HINTS FOR OPTIMUM USE

Drilling
f Always apply a light pressure in a straight line with
the drill bit.
f Just before the drill tip breaks through the other side
of the workpiece, decrease pressure on the tool.
f Use a block of wood to back up workpieces that may
splinter.
f Use spade bits when drilling large diameter holes in
wood.
f Use HSS drill bits when drilling in metal.
f Use masonry bits when drilling in soft masonry.
f Use a lubricant when drilling metals other than cast
iron and brass.
f Make an indentation using a centre punch at the
centre of the hole to be drilled in order to improve
accuracy.
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.

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.
ACCESSORIES
Recommended accessories for use with your tool are
available from your local dealer or authorized service
center.
