Adjusting The Riving Knife - Bosch GTS 18V-216 Professional Manual Original

– Pull or push the hand wheel (14) along the slotted link un-
til the angle indicator (21) shows the required bevel
angle.
– Hold the hand wheel in this position and retighten the
locking lever (20).
For quick and precise setting of the standard bevel
angles of 0° and 45°, there are pre-set stops ((22)),((18)).
Setting mitre angles (angle guide) (see figure C)
The mitre angle can be set between 30° (left-hand side) and
30° (right-hand side).
– Loosen the locking knob (54) if it is tightened.
– Turn the angle guide until the angle indicator (55) shows
the required mitre angle.
– Retighten the locking knob (54).
Adjusting the parallel guide
The parallel guide (5) can be positioned on either the left
(black scale) or the right (silver scale) of the saw blade. The
marking in the scale display (56) shows the set distance
between the parallel guide and the saw blade on the
scale (1).
Position the parallel guide on the required side of the saw
blade (see "Fitting the parallel guide (see figure e)",
page 38).
Adjusting the parallel guide
when the saw table is not pulled out
– Loosen the clamping handle (41) of the parallel
guide (5). Move the parallel guide until the marking in the
scale display (56) indicates the required distance from
the saw blade.
When the saw table is not pulled out, the lower marking
on the silver scale (1) applies.
– To secure it in place, push the clamping handle (41) back
down.
Adjusting the parallel guide
when the saw table is pulled out (see figure D)
– Position the parallel guide on the right of the saw blade.
Move the parallel guide until the marking in the scale
display (56) shows 29 cm on the lower scale.
To secure it in place, push the clamping handle (41) back
down.
– Pull the clamping handle (13) for the saw table expansion
all the way up.
– Pull out the saw table expansion (6) until the spacing
indicator (57) shows the required distance from the saw
blade on the upper scale.
– Push the clamping handle (13) down.
This fixes the saw table expansion in place.
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).
Bosch Power Tools
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.
Start-up
Switching on (see figure G1)
– To start the tool, squeeze both sides of the on/off
switch (16) and pull it upwards.
