Adjusting The Riving Knife; Practical Advice - Bosch GTS 18V-216 Professional Notice Originale

Adjusting the additional parallel guide (see
figure E)
To saw narrow workpieces and bevel angles, you must fit
the additional parallel guide (43) on the parallel guide (5).
The additional parallel guide can be fitted on the left or right
of the parallel guide (5) as required.
When sawing, workpieces can become jammed between the
parallel guide and the saw blade, caught in the saw blade as
it rises and ejected.
You should therefore set the additional parallel guide so that
the end of the guide is between the front tooth of the saw
blade and the front edge of the riving knife.
– To do so, loosen all wing nuts of the fastening set (44)
and move the additional parallel guide until only the front
two screws are used for attachment.
– Retighten the wing nuts.

Adjusting the riving knife

The riving knife (4) prevents the saw blade (26) from be-
coming jammed in the kerf. Otherwise there is a risk of kick-
back occurring if the saw blade catches in the workpiece.
It is therefore important to ensure that the riving knife is set
up correctly:
– The radial clearance between the saw blade and the riving
knife must not exceed 3−8 mm (max.).
– The thickness of the riving knife must be smaller than the
cutting width and larger than the base blade thickness.
– The riving knife must always be aligned with the saw
blade.
– For normal cuts, the riving knife must always be in the
highest possible position.
Adjusting the riving knife height (see figure F)
The height of the riving knife must be adjusted in order to
saw grooves.
Only use the power tool for grooving or routing if a
u
suitable protective guard (e.g. tunnel blade guard,
featherboard) is in place.
– Open the clamping lever (39) and pull the protective
cover (3) out of the groove on the riving knife (4).
To prevent damage to the protective guard, store it in the
bracket (11) provided on the housing (see figure O2).
– Turn the crank (15) clockwise as far as possible so that
the saw blade (26) is in the highest possible position
above the saw table.
– Release the clamping lever (36) clockwise until it points
upwards.
– Pull the riving knife off the pins (37) (pull the clamping
lever (36) outwards slightly) and push the riving knife (4)
down as far as possible.
– Allow both pins (37) to engage in the upper bore holes in
the riving knife and then retighten the clamping
lever (36).
The markings (35) on the clamp and clamping lever (36)
must be aligned as shown.
Bosch Power Tools
Start-up
Switching on (see figure G1)
– To start the tool, squeeze both sides of the on/off
switch (16) and pull it upwards.
Switching off (see figure G2)
– Press the on/off switch (16) all the way downwards.
Protection against unauthorised use (see figure G3)
To protect against unauthorised use, you can lock the on/off
switch (16) with a padlock.
– Push a padlock with a long shackle through the hole in the
on/off switch (16) and lock it.

Practical advice

General sawing instructions
Before making any cuts, first make sure that the saw
u
blade cannot come into contact with the stops or any
other parts of the tool at any time.
Only use the power tool for grooving or routing if a
u
suitable protective guard (e.g. tunnel blade guard,
featherboard) is in place.
Do not use the power tool for cutting slots (stopped
u
grooves).
Protect the saw blade against impact and shock. Do not sub-
ject the saw blade to lateral pressure.
The riving knife must be aligned with the saw blade in order
to prevent the workpiece from jamming.
Do not saw workpieces that have become bent or twisted
out of shape. The workpiece must always have a straight
edge to face against the parallel guide.
Always store the push stick on the power tool.
Position of the operator (see figure H)
Never stand directly in line with the saw blade. Always
u
position your body on the same side of the saw blade
as the fence. Kickback may propel the workpiece at high
velocity towards anyone standing in front and in line with
the saw blade.
– Keep hands, fingers and arms away from the rotating saw
blade.
Pay attention to the following instructions:
– Hold the workpiece firmly with both hands and press it
securely against the saw table.
– When using narrow workpieces or sawing bevel angles, al-
ways use the push stick (12) and the additional parallel
guide (43) provided.
