4) To start press the button
(Fig. A pos.1)
.
The switch is a ‘maintained action’ switch so
the electrical tool will stay on when you keep
the switch pressed.
Stopping
To stop the drill release the switch
(Fig. A pos.1)
.
If you notice any working defects, switch off
the electrical tool and consult the chapter “Pro-
blems, causes and solutions”.
When not using the tool, turn it off.
OPERATIONAL TIPS
After reading the previous chapters carefully,
apply these tips scrupulously to obtain maximum
performance.
Proceed calmly so as to become familiar with
all the controls; after having gained sufficient
experience you will be able to make full use of
its potential.
ELECTRONIC CHUCK SPEED ADJUSTMENT
Press the switch
(Fig. A pos.1)
gradually until
the desired speed is reached. With less pressure
low speeds are obtained, whereas with more
pressure high speeds are obtained.
CHUCK ROTATION DIRECTION REGULATION
(fig. C)
IMPORTANT! The rotation direction inversion
operation must be performed with the tool off
and the chuck stationary.
For drilling operations and tightening right thread
screws (clockwise), move the rotation direction
switch
(Fig. A pos.2)
to ‘
R
’.
For unscrewing operations, or removal of em-
bedded bits and tightening left thread screws
(anti-clockwise), move the rotation direction
switch
(Fig. A pos.2)
to ‘
L
’.
MECHANICAL CHUCK SPEED ADJUSTMENT
IMPORTANT! The mechanical speed adjustment
operation must be performed with the tool off
and the chuck stationary.
By moving the switch
(Fig. A pos.10)
it is pos-
sible to mechanically select the desired speed.
Speed 1: low number of revolutions and high tor-
que (for holes with a large diameter or screwing
large screws into a hard material).
Speed 2: high number of revolutions and low
torque.
FRICTION REGULATION
The friction can be adjusted from
‘1’
to the
maximum setting
and normally only needs
adjusting for screwing operations. Using the
ring nut to vary the tightening torque
(Fig. A
pos.5)
, match up one of the values indicated
with the reference on the top of the drill body,
remembering that:
- ‘
1
’ corresponds to minimum torque, to use for
screw small screws in soft material.
- the torque increases with the number indica-
ted on the ring nut until the maximum value is
reached , to use for drilling.
In some models to adjust the torque it is neces-
sary for the screwing symbol to be selected
on the percussion ring nut
(Fig. A pos.11)
at the
same time; it is also possible that the maximum
torque position is dislocated on the same
percussion ring nut instead of on the torque
adjustment one.
PERCUSSION ACTIVATION / DEACTIVATION
Turn the ring nut
(Fig. A pos.11)
to the symbol
for activating the percussion function, or to
any other position to deactivate it.
LIGHTING FOR WORK AREA
The light
(Fig. A pos.7)
comes on or off auto-
matically when the tool is switched on.
CHANGING THE CUTTING TOOL
See chapter “STARTING UP”.
DRILL BITS
Buy good quality bits, with a suitable connection
for the characteristics of the chuck and suitable
for the material to be drilled. Contact your retailer
who will be able to give you the best advice.
Our company produces a wide range of bits
suitable for the various uses (metal, wood,
brick, etc.).
DRILLING OPERATION
Always secure items in a vice when drilling. Use
a punch to mark the initial drilling point. Keep
the drill bits sharp. To drill large holes first drill a
number of small holes to avoid the bit jamming
in the hole and thus overloading the tool.
Reduce the drilling pressure when the bit is
nearly out of the item.
Be cautious with the sawdust produced which
is very hot and also very sharp. Wear goggles
and protective gloves!
