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.
Set the percussion function
(Fig. A pos.11)
to facilitate the action of the bit. For drilling tiles
deactivate the percussion function, to prevent
the tile cracking unexpectedly.
SCREWING INSERTS (BITS)
Buy only high quality inserts with connection
suitable for the characteristics of this screwdri-
ver 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
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 be fixed there
is a suitable type of bolts and screws; therefore,
buy it according to necessity. If necessary, use
washers to increase the surface area.
SCREWING OPERATION
Place the screw on the panel to be fixed and
with a hammer tap it lightly in a perpendicular
position.
For some materials it is necessary to make a
pre-hole in order to facilitate the screwing and
to prevent the panel breaking (especially with
wood and plastic).
Grip the screwdriver firmly with one hand and
insert the tip of the bit in the screw head. Lightly
press on the screw and run the screwdriver,
activating the switch gradually so as to modulate
the rotating speed and, consequently, the speed
of screw penetration.
At the end of this operation, which usually lasts
a few seconds, remove the screwdriver and turn
it off by releasing the switch.
The screwing speed depends on the following
factors: panel material, screw size, thread, pre-
sence or absence of a pre-hole, etc.
After the screwing phase, the internal rotation
joint will be uncoupled, the electrical tool will
become very noisy and will vibrate; now, remove
the screwdriver and turn it off.
Continuing to screw may cause: the breakage of
the insert, damage to the screw head, and failure
of the electrical tool (in this case not covered by
the warranty). In this case, unscrew the screw,
perform a pre-hole with a driller and re-screw
modifying the adjustments.
Do not force screws that do not screw!
MAINTENANCE
!
!
IMPORTANT! Before any checks or
adjustments take the battery out of the tool
and unplug the battery charger from the mains.
!
!
IMPORTANT! Do not tamper or attempt to
repair the electrical tool.
The working life and costs also depend on con-
stant and meticulous maintenance.
Take good care of your electrical tool and clean it
regularly. In this way its efficiency will be ensured
and its lifespan extended.
- Remove dust and machining residuals with a
brush with soft bristles.
- Do not wet or spray water over the electrical
tool - risk of internal infiltrations.
- Do not use any inflammables, detergents or
solvents.
- The plastic parts can easily be damaged by
chemical agents.
- Do not use compressed air for cleaning: Risk
of material ejection!
- Be careful when cleaning the switch, motor
fan slots, chuck, battery and battery charger.
The tool does not require any special maintenan-
ce inasmuch as it is lubricated with permanent
grease inside. Any internal servicing must only
