Unlocking the Glide Arm (see figure B1)

After unlocking the glide arm

(23)

, the whole gliding mech-

anism is ready for operation.
– Press the clamping lever

(2)

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

(23)

all the way back.

– The two articulated parts at the top of the glide arm are

now upright and closed.

– Pull the clamping lever

(2)

upwards until the clamping

wedge is positioned between the two articulated parts at
the bottom of the glide arm.

– This locks the glide arm

(23)

, which is pushed all the way

back.

Glide arm pulled all the way forward:
– Pull the glide arm

(23)

all the way forward.

– The glide mechanism is now completely extended.
– Pull the clamping lever

(2)

upwards until the clamping

wedge is positioned between the two articulated parts at
the bottom of the glide arm.

– This locks the glide arm

(23)

, 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 workpiece support on the saw table can be extended left
and right using the extension bar

(16)

– Push the clamping lever

(18)

inwards.

– Pull out the extension bar

(16)

to the required length

(maximum 204 mm).

– To lock the extension bar in place, push the clamping

lever

(18)

back out.

Moving the fence (see figures D–E)

When sawing mitre and/or bevel angles, you have to pull the left-hand or right-hand adjustable fence

(7)

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

(23)

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

(47)

Hard – for more controlled work movements;
Soft – for fast saw cuts.
– For

softer

damping, loosen the two set screws

(48)

using

the hex key (

mm)

(30)

–

– tighten the two set screws

(48)

for

harder

damping.

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 fence

(8)

– Insert the supplied screw clamp

(19)

into one of the holes

(49)

intended for this purpose.

– Firmly clamp the workpiece by turning the threaded rod

(50)

Setting mitre and bevel angles

To ensure precise cuts, the basic settings of the power tool
must be checked and adjusted as necessary after intensive
use.
Experience and suitable special tools are required for this.
A Bosch after-sales service point will handle this work
quickly and reliably.

Always tighten the locking knob

(11) firmly before

sawing.

Otherwise the saw blade can become wedged in

the workpiece.
