length of the bit.
. Read the value in mm off the scale on the depth gauge
G and subtract the required drill depth.
. Mains connection
Warning! Connect only to a single-phase AC current supply
and only to the mains voltage specified on the rating plate.
Connection to sockets without earth protection is possible as
the appliance features protective class II insulation according
to European Standard EN60745. Radio interference
suppression complies with the European Standard EN
55014.
FUNCTIONS
. Electronic speed selection
The speed can be controlled in infinitely variable steps
by adjusting finger pressure on the On/off switch J. The
electronic regulation built-in the switch trigger J allows to
adjust the speed suitable for the material to be worked. It's
advisable to start the drill at low speed so that the drill does
not move from the intended centre.
On cast iron and high strength steels, low speed is
advisable.
On plastics, timber, aluminium, copper, soft bronze and
brass, high speeds are advisable.
2. Switching over between drilling and hammer drilling (fig.
1)
To work in hammer mode, shift button E to the area marked
by a hammer symbol.
To work without hammer, shift button E to the area marked
by a drill bit symbol.
Striking mechanism may be turned on while the machine is
running.
Use hard metal drill bits to work with concrete, stone and
rubblework.
Only ever switch over when the machine is stationary or
slowing down. Only ever operate the machine rotating
clockwise when drilling.
. Switching between forward and reverse
These models are provided with a reversing lever in the
switch which allows the drill to be used as an screw-driver.
Select direction of rotation with turn direction lever I as shown
on label O, i.e., R=right sense, L=left sense.
Due to a lockout mechanism, the turn direction lever I can
only be switched when the On-/off switch J is not depressed.
Only enable the turn direction lever I when the machine has
stopped.
Only ever operate the machine rotating to the right when
hammer-drilling or when chiselling!
. Switching the tool on and off
Intermittent use
Switching on: Press trigger switch J.
Switching off: Release trigger switch J.
Continuous use
Switching on: Press the On-/off switch J and then the locking
button K, after that release on-off switch J.
Switching off: Press the On-/off switch J and then re-lease.
The speed can be controlled continuously during the
operation by adjusting finger pressure on the On-/off switch.
OPERATION
1. Hammer-drilling
1. Set the following adjustments before starting work:
- Shift button E to the area marked by a hammer sym-
bol.
- Clockwise rotation.
. Fit the drill.
. Place the drill against the material before switching it on,
press it until the lengthways play is taken up, then switch on
and work exerting light pressure (e.g. 30N).
Note Exerting greater pressure does not increase the
machine's effectiveness!
Tips on drilling in masonry:
• Take the drill out of the hole from time to time to re-move
dust.
• Switch to percussion-drilling for concrete, hard bricks
and tiles, stone and hard cement (but not when drilling the
surface of marble).
• For tiles, paving-stones, soft bricks and tiles, soft
cement, breeze-block and plaster, switch to normal drilling.
• Use percussion carbide-tipped masonry drill-bits.
• When drilling a hard, smooth surface (e.g. tiles), cover
the point to be drilled with adhesive tape in order to prevent
the drill tip from skidding.

MAINTENANCE AND CARE

WARNING-Always unplug the machine before carrying out
work on it.
- When you notice a decrease in hammer output, take the
machine to an Official Service Centre.
- Tool inspection: Using a blunt cutting tool leads to less
efficient work and could damage the motor, there fore cutting
tools should be sharpened or replaced as soon as any wear
is noticed. Daily: Clean the tool holder.
- Inspect the mounting screws: Regularly inspect all the
mounting screws and ensure they are firmly tight-ened.
Should any screw be loose, tighten it immediately. Failure to
do so could put you at serious risk.
- Motor maintenance: Take the utmost care to ensure
that the motor winding is not damaged and does not become
damp with oil or water.
- Brush replacement: The brushes disconnect auto-
matically and should be replaced after 150-200 hours use or
when they are less than 10 mm long. Have them replaced by
an Official Service Centre.
- Clean the machine thoroughly after each use with a
blast of dry air.
- The vents of the machine should be kept clear at all
times.
- Check that the mains lead is in good condition. If it is not,
take it to an Official Service Centre to have it replaced.
- Use only Felisatti accessories and spares. The parts the
changing of which is not covered in this instruction manual,
should be replaced in a Felisatti Official Service Centre (See
Warranty/Official Service Centre ad-dress leaflet).
