Product Description And Specifications - stayer IS L20 Manual De Instrucciones

- Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
un­predictable behavior resulting in fire, explosion or risk
of injury.
-Do not expose a battery pack or tool to fire or exces-
sive temperature. Exposure to fire or temperature above
130°C may cause explosion.
- Follow all charging instructions and do not charge
the battery pack or tool outside the temperature ran-
ge specified in the instructions. Charging improperly or
at temperatures outside the specified range may damage
the battery and increase the risk of fire
1.5 Service
- Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will en-sure that the safety of the power tool is maintained.
- Never service damaged battery packs. Service of ba-
ttery packs should only be performed by the manufacturer
or authorised service providers.
1.6 Safety Warnings for Impact Wrenches
- Hold power tool by insulated gripping surfaces,
when performing an operation where the fastener may
contact hidden wiring. Fasteners contacting a "live" wire
may make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
- Secure the workpiece. A workpiece clamped with clam-
ping devices or in a vice is held more secure than by hand.
- Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
- Always wait until the machine has come to a comple-
te stop before placing it down. The tool insert can jam
and lead to loss of control over the power tool.
- Do not open the battery. Danger of short-cir-
cuiting.
- Protect the battery against heat, e.g., against
continuous intense sunlight, fire, water, and
moisture. Danger of explosion.
- In case of damage and improper use of the battery,
vapours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can
irritate the respiratory system.
- Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
- The battery can be damaged by pointed objects such
as nails or screwdrivers or by force applied externa-
lly. An internal short circuit can occur and the battery can
burn, smoke, explode or overheat.

Sound emission values determined according to
EN 60745-2-2.
Typically the A-weighted noise levels of the pro-
duct are: Sound pressure level 93,5 dB(A); Sound
power level 102,5 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and
uncertainty K determined according to EN 60745:
Impact tightening of fasteners of the maximum capacity of
the tool: ah=9,1 m/s2, K=1,5 m/s2.
The vibration level given in this information sheet has
been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool
with anoth-er. It may be used for a preliminary assess-
ment of exposure. The declared vibration emission level
represents the main ap-plications of the tool. However if
the tool is used for different applications, with different ac-
cessories or insertion tools or is poorly maintained, the
vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should
also take into account the times when the tool is switched
off or when it is running but not actually doing the job. This
may significantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the opera-
tor from the effects of vibration such as: maintain the tool
and the accessories, keep the hands warm, organisation
of work patterns.
3. Operation
Method of Operation
The tool holder with the tool is driven by an electric motor
via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in action).
The impact mechanism is activated as soon as the
screwed connection runs tight and thus load is put on the
motor. In this instance, the impact mechanism converts
the power of the motor to steady rotary impacts. When
loosening screws or nuts, the process is reversed..
Starting Operation
Inserting the battery
Set the rotational direction switch located over the trigger
to the centre position to protect the power tool against
accidental starting.
Insert the charged battery from the front into the base of
the power tool until the battery is securely locked.
Reversing the rotational direction
The rotational direction switch is used to reverse the
rota-tional direction of the machine. However, this is not
possible with the On/Off switch actuated.
Right rotation: For driving in screws and tightening nuts,
un- press the rotational direction switch through to the left
stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch through to the
right stop.
