cal) (see figure a)
When mounting the lock lever 14, use the fastening set pro-
vided (socket spanner, nut, 2 washers).

washer, lock lever, small washer, nut) on the threaded bolt
of the machine.

insert the Allen key 30 provided into the holes of the sock-
et wrench.
– Tighten the nut firmly.
Mounting the Extension Bars (see figure b)

hole on the saw table 33.
– Screw the knurled screw by hand in the appropriate hole.
– Place the lock lever 18 on the head of the knurled screw.
– Fix the lock lever 18 with the spring screw.
– Increase the clamping force of the lock lever 18, by tight-
ening the spring screw with the Allen key 30 provided.
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 d1)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 9 serve for this pur-
pose.
Mounting to a Bosch Saw Stand
(GTA 2500 W, GTA 3700, GTA 3800) (see figure d2)
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.
 Read all safety warnings and instructions included with
the worktable. Failure of observing safety warnings and
instructions 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
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.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
