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 82 dB(A); sound power level
93 dB(A). Uncertainty K = 3 dB.
Wear hearing protection
Total vibration values a (triax vector sum) and uncertainty K
h
determined according to EN 62841-2-5:
Sawing wood: a < 2.5 m/s 2 , 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.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
1 609 92A 4LK | (22.10.2018)
is discharged, the power tool is switched off by means of a
GKS 12V-26
protective circuit: The application tool no longer rotates.
GAL 12..
Do not continue to press the On/Off switch after the
u
AL 11..
power tool has automatically switched off. The battery
can be damaged.
Follow the instructions on correct disposal.
Removing the battery
The battery (1) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release button
(2) is pressed unintentionally. As long as the battery is inser-
ted in the power tool, it is held in position by means of a
spring.
To remove the battery (1), press the release button (2) and
pull the battery to the rear and out of the power tool. Do not
use force to do this.
Battery Charge Indicator
2
The three green LEDs of the battery charge indicator (15) in-
dicate the state of charge of the battery (1). For safety reas-
ons, it is only possible to check the state of charge when the
power tool is at a standstill.
Press the on/off switch (4) halfway or completely to display
the state of charge.
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 on/off switch (4), then
the battery is defective and must be replaced.
Inserting/changing the circular saw blade
Remove the battery before carrying out any work on
u
the power tool.
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
power tool. If accessories run faster than their rated
speed, they may break and fly off.
Do not use abrasive wheels as the application tool un-
u
der any circumstances.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions.
Removing the saw blade (see figure A)
To change tools, we recommend that you place the power
tool down on the front side of the motor housing.
– Press and hold the spindle lock button (6).
