Continuous operation (if fitted)
For continuous operation it is necessary to press the button
(pos. 21) so as to lock the switch after the start-up phases.
Then to stop the machine tool press the switch (pos. 1) and
release it immediately.
IMPORTANT! When working with the switch in continuous
mode, never let go of the grip on the main handle so that,
in the event of danger, you can immediately stop the tool.
We recommend repeating these operations several times before
starting work, in order to familiarise yourself with the controls
as far as possible.
If you notice any working defects, switch off the electrical tool
and consult the chapter "Problems, 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 (if fitted)
Press the switch (pos.1) gradually until the desired speed is
reached. With less pressure low speeds are obtained, whereas
with more pressure high speeds are obtained.
MECHANICAL CHUCK SPEED ADJUSTMENT (if fitted)
IMPORTANT! The rotation direction inversion operation must be
performed with the tool off and the chuck stationary.
By moving the switch (pos.14) it is possible to mechanically
select the desired speed.
Speed 1: low number of revolutions and high torque (for holes with
a large diameter or screwing large screws into a hard material).
Speed 2: high number of revolutions and low torque.
CHUCK SPEED RANGE ADJUSTMENT (if fitted)
Rotate the grain roller (pos.20) situated on the switch:
direction + to increase
direction – to decrease.
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 (pos.2) to 'R'.
For unscrewing operations, or removal of embedded bits and
tightening left thread screws (anti-clockwise), move the rotation
direction switch to 'L'.
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 (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 indicated on the ring
nut until the maximum value is reached , to use for drilling.
In some models to adjust the torque it is necessary for the
screwing symbol
to be selected on the percussion ring nut
(pos.9) 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 (if fitted)
Turn the ring nut (pos.9) to the symbol
percussion function, or to any other position to deactivate it.
LIGHTING FOR WORK AREA (if fitted)
The light (pos.18) comes on or off automatically when the tool
is switched on.
If there is a switch (28), operate it to turn on / off.
BATTERY CHARGING INDICATOR (fig.F, if fitted)
According to the model in your possession, there may be an
indication of the battery charging status (pos.15), as part of the
tool or in the battery itself. Refer to fig.F (if fitted) and if necessary
press the button in the indicator itself.
CHANGING THE CUTTING TOOL AND INSERT
See chapter "STARTING UP".
DRILL BITS (not supplied)
Buy good quality bits, with a suitable connection for the cha-
racteristics 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!
Drilling metal
Use HSS bits. If the item is a thin metal sheet, place a block
of wood under the metal sheet to prevent the bit getting stuck.
To drill a cast iron item, use bits suitable for this material.
With steel items, use special liquid coolant; with aluminium use
paraffin as a coolant, whereas with brass and cast iron do not
use liquids but take the bit out of the hole frequently to allow
it to cool down.
Drilling wood and plastic
Always use bits that are suitable for drilling wood and plastic.
Keep in mind that they are fragile materials and it is possible
that the item can crack during drilling.
Drilling bricks
Always use bits with hard metal inserts (such as Widia etc.)
that must always be in good condition. Apply a constant drilling
pressure throughout the job. Frequently take the bit out of the
hole to remove dust.
If fitted, set the percussion function (pos.9) to facilitate the action
of the bit. For drilling tiles deactivate the percussion function, to
prevent the tile cracking unexpectedly.
SCREWING INSERTS (BITS) (not supplied)
Buy only high quality inserts with connection suitable for the
characteristics of this screwdriver and with a push rod suitable
for the screws in use. Contact your retailer who will be able to
give you the best advice.
Our company produces a wide range of inserts suitable for the
various uses.
SCREWS (not supplied)
It is important to use high quality bolts and screws so as to
obtain the best possible final result. For each kind of material to
for activating the
