Assembly
 Avoid unintentional starting of the machine. During as-
sembly and for all work on the machine, the power plug
must not be connected to the mains supply.
Delivery Scope
Carefully remove all parts included in the delivery from their
packaging.
Remove all packaging material from the machine and the
accessories provided.
Before starting the operation of the machine for the first time,
check if all parts listed below have been supplied:
– Sliding mitre saw with mounted saw blade
– Locking knob 15
– Dust bag 1
– Hex key 20
– Hex key 21
(below laser protection cap 27)
– Material clamp 22
Note: Check the power tool for possible damage.
Before further use of the machine, check that all protective
devices are fully functional. Any lightly damaged parts must
be carefully checked to ensure flawless operation of the tool.
All parts must be properly mounted and all conditions fulfilled
that ensure faultless operation.
Damaged protective devices and parts must be immediately
replaced by an authorised service centre.
Additionally required tools (not in delivery scope):
– Cross-head screwdriver
– Open-end spanner (size: 8 mm)
– Ring, open-end or socket spanner (size: 10 mm and
17 mm)
Mounting the Locking Knob (see figure a)
– Screw the locking knob 15 into the corresponding drill
hole above the lever 16.
 Always tighten the locking knob 15 firmly before saw-
ing. Otherwise the saw blade can become wedged in the
workpiece.
Stationary or Flexible Mounting
 To ensure safe handling, the machine must be mounted
on a level and stable surface (e. g., workbench) prior to
using.
Mounting to a Working Surface (see figure b1)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 12 serve for this pur-
pose.
Mounting to a Bosch Saw Stand
(GTA 2500 W, GTA 3700, GTA 3800) (see figure b2)
With the height-adjustable legs, Bosch GTA saw stands pro-
vide firm support for the power tool on any surface. The work-
piece supports of the saw stand are used for underlaying long
workpieces.
Bosch Power Tools
 Read all safety warnings and instructions included with
the worktable. Failure to observe safety warnings and in-
structions can lead to electrical shock, fire and/or cause
serious injuries.
 Assemble the worktable properly before mounting the
power tool. Perfect assembly is important in order to pre-
vent the risk of collapsing.
– Mount the power tool in transport position on the saw
stand.
Dust/Chip Extraction
 Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.
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.
Integrated Dust Extraction (see figure c)
For basic dust collection, use the dust bag 1 provided.
 Check and clean the dust bag each time after using.
 When sawing aluminium, remove the dust bag to avoid
the risk of fire.
– Insert and turn dust bag 1 onto the extraction adapter 2 in
such a manner that the pin of the extraction adapter engag-
es in the recess of the dust bag.
During sawing, the dust bag and the extraction adapter may
never come in contact with moving tool components.
Always empty the dust bag in good time.
External Dust Extraction
For dust extraction, you can also connect the extraction
adapter 2 to a vacuum hose (Ø 35 mm).
– Insert the vacuum hose into the extraction adapter 2.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
