– Ring spanner, open-ended spanner or socket spanner
(sizes: 10 mm and 17 mm)
Fitting individual components
– Carefully remove all parts included in the delivery from
their packaging.
– Remove all packing material from the power tool and the
accessories provided.
Fitting the locking knob (see figure a)
– Screw the locking knob (11) into the corresponding hole
above the lever (12) .
u
Always tighten the locking knob (11) firmly before
sawing.
Otherwise the saw blade can become wedged in
the workpiece.
Fitting the Clamping Handle for Various Bevel Angles
(see figure a)
To fit the clamping handle (13) , use the fastening set
provided (socket spanner, nut, two washers).
– Place the individual components in the order shown
(large washer, clamping handle, small washer, nut) onto
the threaded bolts on the power tool.
– For better power transfer when tightening the nut, insert
the hex key (30) provided through the holes on the
socket spanner.
– Tighten the nut.
Fitting the Extension Bar (see figure b)
To fit the extension bar (16) , use the fastening set provided
(two clamping levers (18) , two spring bolts, two knurled
screws).
– Slide the extension bar
(16) in as far as it will go into the
corresponding holes in the saw table (33) .
– Drive the knurled screws by hand into the corresponding
holes.
– Place the clamping lever (18) on the head of the knurled
screw.
– Fix the clamping lever (18) in place using the spring bolt.
– Increase the clamping force of the clamping lever (18) by
tightening the spring bolts using the hex key (30)
provided.
Stationary or flexible mounting
u
To ensure safe handling, the power tool must be
mounted on a flat, stable work surface (e.g. work
bench) before use.
Mounting on a work surface (see figure c1)
– Use suitable screw fasteners to secure the power tool to
the work surface. The holes (15) are used for this pur-
pose.
or
– Firmly clamp the base of the power tool to the work sur-
face with commercially available screw clamps.
Mounting on a Bosch saw stand
(see figure c2)
( GTA 2500 W , GTA 3700 , GTA 3800 )
With the height-adjustable legs, Bosch GTA saw stands
provide firm support for the power tool on any surface. The
workpiece supports of the saw stand are used for underlay-
ing long workpieces.
u
Read all the warnings and instructions included with
the saw stand.
Failure to observe the warnings and fol-
low instructions may result in electric shock, fire and/or
serious injury.
u
Assemble the saw stand properly before mounting the
power tool.
Correct assembly is important to prevent the
risk of collapsing.
– Mount the power tool on the saw stand in the transport
position.
Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
u
Avoid dust accumulation at the workplace. Dust can
easily ignite.
The dust/chip extraction system can be blocked by dust,
chips or fragments of the workpiece.
– Switch the power tool off and pull the mains plug out of
the socket.
– Wait until the saw blade has come to a complete stop.
– Determine the cause of the blockage and eliminate it.
Self-generated dust extraction (see figure d)
For basic chip collection, use the dust bag (1) provided.
– Place the dust bag (1) onto the extraction adapter (35)
and turn so that the pin of the extraction adapter locks in
place in the recess of the dust bag.
During sawing, the dust bag must not come into contact with
moving tool components.
Always empty the dust bag in good time.
u
Check and clean the dust bag each time after using.
u
When sawing aluminium, remove the dust bag to avoid
the risk of fire.
