Adjusting the Flush Levelling: (see figure C2)
– Turn thumbwheel 47 until the parallel laser beam is flush to

the laser beam from right to left.
Mounting the Table Extension and the
Fences/Stops
Mounting the Table Extension (see figure D)
The table extension 27 is used to widen or extend the saw ta-
ble 7. It can be mounted either on the left or right side, or to
the rear of the saw table.
For assembly, use the fastening kit for the "table extension"
48. (rotary knob 52, socket bolt, nut)
– Slide or insert the table extension 27 into the desired
guide groove 8 of the saw table.
When the table extension is mounted left or right from the saw
table, it is supported toward the front.
When the table extension is mounted to the rear of the saw ta-
ble, it can be supported toward the left or the right.
– Move the table extension until the lower holding prongs of
the support leg 49 are aligned with one of the mounting
holes 9.
If required, move the upper fastening plate of the support
leg 49.
For this, loosen both Allen screws 50 with Allen key 13,
move the upper fastening plate until the support leg 49 is
aligned with the desired mounting hole 9, and retighten
the Allen screws 50 again.
– Place the nut into the mounting hole 9 and screw the hold-
ing prongs of the support leg to the saw table with the sock-
et bolt.
– Screw rotary knob 52 for locking the table extension into
the bolt hole intended for it, and tighten it.
The table extension must be flush with the saw table surface.
– Adjust the correct height of the table extension 27 with ro-
tary knob 51.
Mounting the Universal Guide (see figure E)
The universal guide 1 can be mounted left or right on the saw
table 7, or to the table extension 27.
Note: When sawing bevel angles, the universal guide should
be mounted to the right of the saw blade.
– Slide or insert the extension plate 30 of the universal guide
into the desired guide groove 8 of the saw table or into the
guide groove of the table extension 27.
– Screw rotary knob 38 for locking the universal guide into
the bolt hole intended for it, and tighten it.
Mounting the Fence to the Universal Guide
The fence 36 of the universal guide is used as a supporting
surface for the workpiece.
When sawing narrow workpieces, the fence 36 should be
mounted flush to universal guide 1 in order to prevent jam-
ming or slipping of the workpiece. (see figure F1)
Bosch Power Tools
When sawing high workpieces and when sawing with slide
action, the fence 36 should be mounted upright to the univer-
sal guide 1, so that the supporting surface of the workpiece is
as large as possible. (see figure F2)
– Loosen wing bolt 34.
– Slide the fence 36 either upright or flat onto the guide
tongue 53 of the universal guide.
– Tighten wing bolt 34 again.
Mounting to a Working Surface (see figure G)
 To ensure safe handling, the machine must be mounted
on a level and stable surface (e. g., workbench) prior to
using.
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 9 serve for this pur-
pose.

Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dusts, such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
– Always use dust extraction.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
The dust/chip extraction can be blocked by dust, chips or
workpiece fragments.
– Switch the machine off and pull the mains plug from the
socket outlet.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and correct it.
Cleaning the Lower Saw Blade Cover (see figure I)
A cleaning flap 55 located in the lower saw blade cover 54 can
be opened for removal of workpiece fragments and large
chips.
– Switch the machine off and pull the mains plug from the
socket outlet.
– Wait until the saw blade has come to a complete stop.
– Remove table extension 27 and universal guide 1.
– Tilt the machine on it's side.
– Remove bottom plate 39.
– Open cleaning flap 55 of the lower saw blade cover 54 and
remove workpiece fragments and chips.
– Shut the cleaning flap and screw the bottom plate on again.
– Bring the machine back to the working position and mount
all attachment parts.
