Locking the Glide Arm
The glide mechanism of the glide arm (33) can be locked
with the clamping lever (24). The glide arm can be placed in
two positions:
– Glide arm pushed all the way back (for cross cuts)
– Glide arm pulled all the way forward (for a compact trans-
port position)
Unlocking the Glide Arm (see figure B1)
After unlocking the glide arm (33), the whole gliding mech-
anism is ready for operation.
– Press the clamping lever (24) all the way down.
– The clamping wedge of the clamping lever releases the
two articulated parts at the bottom of the glide arm.
Securing the Glide Arm (see figure B2)
Glide arm pushed all the way back:
– Push the glide arm (33) all the way back.
– The two articulated parts at the top of the glide arm are
now upright and closed.
– Pull the clamping lever (24) upwards until the clamping
wedge is positioned between the two articulated parts at
the bottom of the glide arm.
When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence (6) outwards depending
on the cutting direction, or remove it completely.

Adjusting the damping of the glide arm (see figure F)
The glide mechanism of the glide arm (33) is preset at the
factory and is not damped when the power tool is delivered.
The damping of the glide mechanism can be adjusted using
the damper (58):
Hard – for more controlled work movements;
Soft – for fast saw cuts.
– For softer damping, loosen the two set screws (59) using
the hex key (4 mm) (17)
– or
– tighten the two set screws (59) for harder damping.
Bosch Power Tools
– This locks the glide arm (33), which is pushed all the way
back.
Glide arm pulled all the way forward:
– Pull the glide arm (33) all the way forward.
– The glide mechanism is now completely extended.
– Pull the clamping lever (24) upwards until the clamping
wedge is positioned between the two articulated parts at
the bottom of the glide arm.
– This locks the glide arm (33), which is pulled all the way
forward.

Preparing for operation

Extending the Saw Table (see figure C)
The free end of long workpieces must have something
placed underneath it or be supported.
The saw table can be extended left and right using the saw
table extensions (8).
– Push the clamping lever (56) inwards.
– Pull out the saw table extension (8) to the required length
(maximum 250 mm).
– To lock the saw table extension in place, push the clamp-
ing lever (56) back out.
Moving the fence (see figures D–E)
– Loosen the locking screw (57).
– Pull the left-hand adjustable fence (6) all the way out.
– Loosen the locking screw (57).
– Pull the left-hand adjustable fence (6) all the way out.
– Lift the adjustable fence upwards and out of the way.
– Remove the locking screw (57).
– Loosen the locking screw (57).
– Pull the right-hand adjustable fence (6) all the way out.
– Lift the adjustable fence upwards and out of the way.
Clamping the workpiece (see figure G)
To ensure maximum safety while working, the workpiece
must always be firmly clamped.
Do not saw workpieces that are too small to clamp firmly.
– Press the workpiece firmly against the fences (7) and (6).
– Insert the supplied screw clamp (19) into one of the cor-
responding holes (60).
– Loosen the wing bolt (61) and adjust the screw clamp to
the workpiece. Tighten the wing bolt again.
– Tighten the threaded rod (62) to fix the workpiece in
place.
Releasing the workpiece
– To loosen the screw clamp, turn the threaded rod (62)
anticlockwise.
