Noise/Vibration Information
Noise emission values determined according to
EN 62841-2-5.
Typically the A-weighted noise level of the power tool is:
Sound pressure level 80 dB(A); sound power level
91 dB(A). Uncertainty K = 3.0 dB.
Wear hearing protection
Total vibration values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-5:
2
Sawing wood: a < 2.5 m/s , K = 1.5 m/s
h
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Fitting
Only use saw blades the maximum permitted speed of
u
which is higher than the no-load speed of the power
tool.
Charging the Battery
Use only the chargers listed on the accessories page.
u
Only these chargers are matched to the lithium-ion bat-
tery of your power tool.
Note: The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the charger
before using your power tool for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging process
does not damage the battery.
Bosch Power Tools
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
Do not continue to press the On/Off switch after the
u
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery
2
The battery (19) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release button
(26) is pressed unintentionally. As long as the battery is in-
serted in the power tool, it is held in position by means of a
spring.
To remove the battery (19), press the release button (26)
and pull the battery to the rear and out of the power tool. Do
not use force to do this.
Battery charge indicator (see figure F)
The three green LEDs of the battery charge indicator (33) in-
dicate the state of charge of the battery (19). For safety
reasons, it is only possible to check the state of charge when
the power tool is at a standstill.
Press the button (32) to show the state of charge.
This is also possible when the battery (19) is removed.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
If no LED lights up after pressing the button (32), then the
battery is defective and must be replaced.
Inserting/changing the circular saw blade
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
Wear protective gloves when fitting the saw blade.
u
Danger of injury when touching the saw blade.
Only use saw blades that match the specifications
u
given in this operating manual and that are tested and
marked in accordance with EN 847-1
The permitted speed of the application tool must be at
u
least equal to the maximum speed marked on the
