Bosch Power Tools

– Turn the power tool the right way round again and screw 

the clamping screws 

2

 for fastening the saw table exten-

sions 

3

 in place into the threaded holes provided in the saw 

table 

22

.

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 

1

 serve for this pur-

pose.

Mounting to a Bosch Saw Stand

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 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.

Flexible Mounting (not recommended!) (see figure B2)

In exceptional cases, when it is not possible to mount the ma-
chine onto a level and stable work surface, it can be set up us-
ing the tilt protector.



Without the use of the tilt protector, the machine does 
not stand safely and can tip over, especially when saw-
ing at maximum mitre/bevel angles.

– Screw the tilt protector 

27

 in or out until the machine is po-

sitioned level on the working surface.

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 carci-
nogenic, especially in connection with wood-treatment addi-
tives (chromate, wood preservative). Materials containing as-
bestos 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.



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.

External Dust Extraction

For dust extraction, a vacuum hose (size Ø 35 mm) can also 
be connected to the chip ejector 

13

. 

– Connect the vacuum hose with the chip ejector 

13

.

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.

Changing the Saw Blade (see figures C1 – C4)



When mounting the saw blade, wear protective gloves. 

Danger of injury when touching the saw blade.

Use only saw blades whose maximum permitted speed is 
higher than the no-load speed of the power tool.

Use only saw blades that correspond with the characteristic 
data given in these operation instructions and that are tested 
and marked in accordance with EN 847-1.

Use only saw blades recommended by the tool manufacturer, 
and suitable for sawing the materials to be cut. This prevents 
overheating of the saw teeth during sawing.

Removing the Saw Blade

– Bring the power tool into the working position.
– Turn  the  hex  socket  screw 

36

 with the hex key (5 mm) 

35

and at the same time press the spindle lock 

29

 until it en-

gages.

– Hold the spindle lock 

29

 pressed and unscrew the hex 

socket screw 

36

 in clockwise direction (left-hand thread!).

– Remove the clamping flange 

37

.

– Press locking switch 

17

 and swing back the retracting 

blade guard 

19

 to the stop.

– Hold the retracting blade guard in this position and remove 

the saw blade 

39

.

– Slowly guide the retracting blade guard downward again.

Mounting the Saw Blade

If required, clean all parts to be mounted prior to assembly.

– Press locking switch 

17

, swing back the retracting blade 

guard 

19

 to the stop and hold it in this position.

– Place the new saw blade onto the interior clamping flange 

38

.



When mounting the saw blade, pay attention that the 
cutting direction of the teeth (arrow direction on the 
saw blade) corresponds with the direction of the arrow 
on the blade guard!

– Slowly guide the retracting blade guard downward again.
– Place on the clamping flange 

37

 and the screw 

36

.

Press the spindle lock 

29

 until it engages and tighten the 

screw turning in anticlockwise direction.
