Practical Advice - Bosch GCM 18V-216 DC Professional Manual Original

42 | English
For all cuts, it must first be ensured that the saw blade
u
at no time can come in contact with the fence, screw
clamps or other machine parts. Remove any mounted
auxiliary stops or adjust them accordingly.
With the Bluetooth® Low Energy Module GCY 42, the
u
power tool is equipped with a radio interface. Local
operating restrictions, e.g. in aircraft or hospitals,
must be observed.
In areas where the Bluetooth® wireless technology is
u
not allowed to be used, the Bluetooth® Low Energy
Module GCY 42 and the button cell must be removed.
The free end of long and heavy workpieces must have some-
thing placed underneath it or be supported.
Do not saw warped/bent workpieces. The workpiece must
always have a straight edge to face against the fence.
Only saw materials which are permitted within the scope of
the intended use.
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
Make sure that the retracting blade guard operates properly
and that it can move freely. The retracting blade guard must
open when the tool arm is guided downwards. When the tool
arm is guided upwards, the retracting blade guard must
close again over the saw blade and lock in the uppermost po-
sition of the tool arm.
Position of the operator (see figure O)
Do not stand in line with the saw blade in front of the
u
power tool. Always stand to the side of the saw blade.
This protects your body against possible kickback.
– Keep hands, fingers and arms away from the rotating saw
blade.
– Do not reach one hand across the other when in front of
the tool arm.
Sawing with slide movement
– For cuts made using the slide device (1) (wide work-
pieces), loosen the locking screw (36) if it is clamping the
slide device in place.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle.
– Pull the tool arm away from the fences (16) and until the
saw blade is in front of the workpiece.
– Switch on the power tool.
– Slowly guide the tool arm downwards using the
handle (9).
– Now push the tool arm towards the fences (16) and and
saw through the workpiece with uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the tool arm upwards.
Sawing Without Slide Movement (cutting off) (see
figure P)
– To perform cuts without slide movement (small work-
pieces), loosen the locking screw (36) if it is clamping the
1 609 92A 7ED | (21.12.2021)
slide device (1) in place. Push the tool arm all the way to-
wards the fences (16) and and retighten the locking
screw (36) to lock the slide device in place.
– Firmly clamp the workpiece as appropriate for its dimen-
sions.
– Set the required mitre and/or bevel angle.
– Switch on the power tool.
– Slowly guide the tool arm downwards using the
handle (9).
– Saw through the workpiece applying uniform feed.
– Switch off the power tool and wait until the saw blade has
come to a complete stop.
– Slowly guide the tool arm upwards.

Practical advice

Marking the Cutting Line (see figure Q)
Two laser beams indicate the cutting width of the saw blade.
This allows for exact positioning of the workpiece for sawing,
without having to open the retracting blade guard.
– Switch on the laser beams using the laser/worklight on/
off button (54).
– Position your mark on the workpiece between the two
laser lines.
Note: Before sawing, check if the cutting width is still indic-
ated correctly . Vibrations during intensive use, for example,
can cause the laser beams to become misaligned.

Minimum workpiece dimensions (= all workpieces that can
be secured left or right of the saw blade using the supplied
screw clamps (30)): 100 x 40 mm (length x width)
Max. cutting depth (0°/0°): 70 mm
Adjusting the depth stop (sawing the groove) (see figure
R)
The depth stop needs to be adjusted if you wish to saw a
groove.
