4. PRODUCT DESCRIPTION
This manual describes battery scissors model NERA which are used in order to cut fabrics in
the textile industry, technical fabrics and light leathers. They are extremely versatile, light
and precise in the cutting operation. The 3.7 V Lithium®-Ion battery-powered miniature
motor, extremely compact and reliable, combined with a special series of blades with a
diameter of 50 mm, ensures cuts of thickness up to 9 mm. The Lithium®Ion battery
develops 2400 mAh and is easily rechargeable with the appropriate docking station complete
with LED indicator. The second battery, included in the package, allows you to cut continuously
without interrupting the work. The strong cutting foot with a thin shape allows the cutting
of curved profiles with great ease. One of the peculiarities of the battery scissors NERA is
the possibility, thanks to the presence of a grinding wheel mounted on the scissors, to be
able to sharpen the blade at any time, without disassembling it. After carrying out this
operation, it is possible to immediately resume cutting operations. A perfectly balanced
motor, with a high number of revolutions and maintenance-free, reduces vibrations to a
minimum, making the battery scissors compliant with the European Directive 2002/44/EC on
the risks deriving from mechanical vibrations. The mechanical parts are made of high quality
steel, bronze and aluminum and require lubrication after several working hours.

9. RESIDUAL RISKS
Even though the battery scissors are safe, operators must pay attention to preserve their
and other people’s safety.
At the end of the working operations, the metallic components could be very hot.
The cutting blade can work even when the protective device is disassembled.
8. USE WARNINGS
We recommend following the indications below in order to always work in safety conditions.
All the operations must be carried out complying strictly with the safety rules of the
country where the device is sold.
It is STRICTLY FORBIDDEN to smoke during the installation or adjustment operations of
the battery scissors.
The Customer undertakes to comply with and make his staff observe all the rules and
regulations in force concerning safety, prevention of accidents and health in the work
place. Therefore, the Customer assumes the responsibility to strictly follow all the rules
and regulations in force, as well as the special provisions in force in sport and public
installations the Customer declares to know after receiving all the relative necessary
pieces of information.
The battery scissors work also without their safety protective device. This
protective device must NEVER be removed.
Always check the resistance of the material to be cut and the kind of blade which is
being used.
The Customer shall equip his own personnel with all the individual safety protections for
the execution of the works, as well as with the ones which might be prescribed by the
Manufacturer due to specific danger conditions of the plant or of the area where the
personnel must work.
Only one operator must use the battery scissors always standing behind the guide
handle. Do not make any adjustment while the blade is working.
It is allowed to assemble battery scissors NERA on machines O.E.M. on condition that
their original structure is not modified. Otherwise, the intervention must be certified by
Rasor®.

10. RULES FOR THE CARE OF THE LITHIUM-ION BATTERIES
The following rules should be noted when caring for your lithium-ion batteries if you want
to maintain the performance of the energy store for as long as possible:
Thefirstchargeiscrucial.Fullychargethebatterybeforeusingitforthefirsttime.
Each battery only has a limited number of charge cycles. Don't therefore recharge
the battery at every opportunity. Instead use it until it is almost flat (10-20% of
charge). Depending on loading, the high-quality, 2,4 Ah capacity battery cells can be
chargedupto500times.Assuming150daysareworkedayearandthatthebatteries
are charged daily, this corresponds to a battery life of 2 years.
If the battery is discharged below its nominal voltage, this can trigger processes
which damage or destroy the battery. The batteries are therefore fitted with
electronics which warn the user and shut down the device before total discharge
can take place.
Frequent overcharging can also permanently damage the battery. The charger
therefore automatically finishes the charging process as soon as the battery is fully
charged.Do not attempt to force more charge into the batteries by unplugging and
reconnecting the charger. Such action will not produce a higher charge - it will only
damage the batteries.
Charging should generally only be undertaken at room temperature (around 18 - 21
degrees). Avoid charging a cold battery as it damages the cells. Always warm the
battery up to room temperature before charging, especially when it is cold outdoors
in winter.
High temperatures also damage the battery. Never leave the battery, and preferably
not the entire tool box, in the car or direct sunlight on hot sunny days. At
temperatures above 60 degrees Celsius, the Li-ion battery permanently loses capacity.
Lithium-ion batteries shouldn't be stored flat or fully charged for long periods. Extensive
testinghasfoundacapacityof40-50%andlowtemperatures(butnotbelow0°C)
to be optimum for storage. Ideally they should be kept at 5°C to 10°C. Recharging
is needed at least every 12 months as the batteries will self-discharge.
A battery which is not being used should be stored in a cool but not cold place. Even
when not being used, batteries lose energy. The Li-ion battery loses 3-5% of its
charge a month.
If a lithium-ion battery is not used for a long period, it should be recharged after 12
months at the latest otherwise it will be irreparably damaged.
Old, used batteries must of course be disposed of in an environmentally friendly
manner.

12. BATTERY CHARGING
When the battery is empty, it is necessary to recharge it using only the special docking
station supplied with the device.
The docking station must be connected to the standard charger with European or American
plug, also supplied with the scissors.
WARNING
Always check if the charger voltage corresponds to the network voltage of the country
where the scissors are used.
Never use chargers other than those supplied (100-
240VAC, 50/60 Hz, 0.4A max - Output: 4,2V, 2A).
Remove the battery "A"fromthemotorbypressing
the appropriate orange "B" buttons on the top and
bottom of the battery (see picture 5), then insert it
into the "C" docking station as shown in picture 6.
Never use batteries other than the one supplied (3,7V
rechargeable with Lithium®Ion technology).
It is possible to control the recharging operation through
the LED light located on both the docking station and
the charger. These LEDs indicate:
- battery charging (red colour)
- fully charged battery (green colour)
Using the standard charger CH36 (with European plug)
or CH3601 (with American plug), the time required for
a full charge is approx. 4 hours.
