Ec Declaration Of Conformity - Berner BACIW BL CO-1 Manual Original

Remove the battery pack before starting any work on the
machine.
Do not dispose of used battery packs in the household
refuse or by burning them. Your power tool distributor will
normally retrieve old batteries to protect our environment.
Do not store the battery pack together with metal objects
(short circuit risk).
Use only System Berner chargers for charging System
Berner battery packs. Do not use battery packs from other
systems.
Never break open battery packs and chargers and store
only in dry rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under
extreme load or extreme temperatures. In case of contact
with battery acid wash it off immediately with soap and
water. In case of eye contact rinse thoroughly for at least
10 minutes and immediately seek medical attention.
Warning! To reduce the risk of fi re, personal injury, and
product damage due to a short circuit, never immerse your
tool, battery pack or charger in fl uid or allow a fl uid to fl ow
inside them. Corrosive or conductive fl uids, such as
seawater, certain industrial chemicals, and bleach or
bleach containing products, etc., can cause a short circuit.
SPECIFIED CONDITIONS OF USE
The cordless impact wrench can be used to tighten and
loosen nuts and bolts wherever no mains connection is
available.
Do not use this product in any other way as stated for
normal use.
RPM SETTING
The function is designed to give the user greater control
in application and reduce damage to the fastener or work
surface by automatically shutting the tool off after the tool
senses the mechanism impacting for approximately one
second.
Max RPM 2000 min-1- tool will shut off after about one
second of impacting

OPERATION
Note: It is recommended after fastening to always
check the torque with a torque wrench.
The fastening torque is aff ected by a wide variety of factors
including the following.
• State of battery charge – When the battery is discharged
voltage will drop and the fastening torque will be reduced.
• Operation at speeds – Operating the tool at low speeds
will cause a reduction in fastening torques.
• Fastening position – Holding the tool or the driving
fastener in various angles will aff ect the torque.
• Drive accessory/socket – Failure to use the correct size
accessory or socket, or a non-impact rated accessory
may cause a reduction in the fastening torque.
• Use of accessories and extensions – Depending on the
accessory or extension fi tment can reduce the fastening
force of the impact wrench.
• Bolt/Nut – Fastening torques may diff er according to the
diameter of the nut or bolt, the class of nut/bolt and the
length of nut/bolt.
• Condition of the fastener – Contaminated, corroded, dry
or lubricated fasteners may vary the fastening torques.
• Condition and base material – The base material of the
fastener and any component in between the surfaces
may eff ect the fastening torque (dry or lubricated base,
soft or hard base, disc, seal or washer between fastener
and base material).
IMPACTING TECHNIQUES
The longer a bolt, screw, or nut is impacted, the tighter it
will become.
To help prevent damaging the fasteners or workpieces,
avoid excessive impacting.
Be particularly careful when impacting smaller fasteners
because they require less impacting to reach optimum
torque.
Practice with various fasteners, noting the length of time
required to reach the desired torque.
Check the tightness with a hand-torque wrench.
If the fasteners are too tight, reduce the impacting time.
If they are not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under the
head of the fastener aff ects the degree of tightness.
The torque required to loosen a fastener averages 75% to
80% of the tightening torque, depending on the condition of
the contacting surfaces.
On light gasket jobs, run each fastener down to a relatively
light torque and use a hand torque wrench for fi nal
tightening.
BATTERIES
Battery packs which have not been used for some time
should be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the
performance of the battery pack. Avoid extended exposure
to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept
clean.
For an optimum life-time, after use, the battery packs have
to be fully charged.
To obtain the longest possible battery life remove the
battery pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below
27°C and away from moisture
Store the battery packs in a 30% - 50% charged condition
Every six months of storage, charge the pack as normal.
