Removing The Battery; Battery Charge Indicator; Fitting Individual Components; Stationary Or Flexible Mounting - Bosch GCM 18V-305 GDC Professional Manual Original

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

Removing the Battery

The battery (31) is equipped with two locking levels to pre-
vent the battery from falling out if the battery release
button (32) is pressed unintentionally. The battery is held in
place by a spring when fitted in the power tool.
To remove the battery , press the release button and pull the
battery out of the power tool. Do not use force to do this.

Battery charge indicator

The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.

Bosch Power Tools

Fitting individual components

– Carefully remove all parts included in the delivery from
their packaging.
– Remove all packing material from the power tool and the
accessories provided.
Fitting the locking knob (see figure a)
– Screw the locking knob (12) into the corresponding hole
above the lever (13).
Always tighten the locking knob (12) firmly before
u
sawing. Otherwise the saw blade can become wedged in
the workpiece.

Stationary or flexible mounting

To ensure safe handling, the power tool must be
u
mounted on a flat, stable work surface (e.g. work
bench) before use.
Mounting on a work surface (see figure b1)
– Use suitable screw fasteners to secure the power tool to
the work surface. The holes (9) are used for this purpose.
or
– Firmly clamp the base of the power tool to the work sur-
to
face with commercially available screw clamps.
Mounting on a Bosch saw stand
(see figure b2)
(GTA 2500 W, GTA 2500 Compact, GTA 2600, GTA
3800)
With the height-adjustable legs, Bosch GTA saw stands
provide firm support for the power tool on any surface. The
workpiece supports of the saw stand are used for underlay-
ing long workpieces.
Read all the warnings and instructions included with
u
the saw stand. Failure to observe the warnings and fol-
low instructions may result in electric shock, fire and/or
Capacity
serious injury.
60−100 %
Assemble the saw stand properly before mounting the
u
power tool. Correct assembly is important to prevent the
30−60 %
risk of collapsing.
5−30 %
– Mount the power tool on the saw stand in the transport
0−5 %
position.

Dust/Chip Extraction

The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
Capacity
people in the near vicinity.
80−100 %
Certain dusts, such as oak or beech dust, are classified as
60−80 %
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
40−60 %
ing asbestos may only be machined by specialists.
20−40 %
– Use a dust extraction system that is suitable for the ma-
5−20 %
terial wherever possible.
0−5 %
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
