– Adjust the blade guard according to the workpiece height.
When sawing, the blade guard must always face lightly
against the workpiece.
– Switch on the machine.
– Saw through the workpiece applying uniform feed.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
Sawing Bevel Angles
– Adjust the desired bevel angle. (see “Adjusting Bevel An-
gles”, page 33)
– Follow the worksteps in section “Sawing Straight Cuts” ac-
cordingly.
Sawing Mitre Angles (see figure S)
– Adjust the requested mitre angle (see “Adjusting Mitre An-
gles”, page 33)
– Place the workpiece against profile rail 28.
The profile may not be on the cutting line. If so, loosen
knurled nut 53 and move the profile.
– Raise or lower the saw blade with the crank 19 so that the
upper saw teeth project approx. 5 mm above the work-
piece surface.
– Adjust the blade guard according to the workpiece height.
When sawing, the blade guard must always face lightly
against the workpiece.
– Switch on the machine.
– With one hand, press the workpiece against the profile rail
and with the other hand, slowly move the angle stop via
locking knob 49 toward the front in guide groove 5.
– Switch off the machine and wait until the saw blade has
come to a complete stop.
Checking and Adjusting the Basic Adjustment
To ensure precise cuts, the basic adjustment of the machine
must be checked and adjusted as necessary after intensive
use.
A certain level of experience and appropriate specialty tools
are required for this.
A Bosch after-sales service station will handle this mainte-
nance task quickly and reliably.
Setting the Stops for Standard 0°/ 45° Bevel Angles
– Bring the power tool into the working position.
– Adjust to a 0° bevel angle.
– Tilt the protection guard 6.x toward the rear to the stop.
Checking: (see figure T1)
– Set an angle gauge to 90° and place it on the saw table 9.
The leg of the angle gauge must be flush with the saw blade 26
over the complete length.
Adjusting: (see figure T2)
– Loosen screw 54.
The 0° stop 55 can now be moved.
– Loosen locking lever 17.
– Move handwheel 18 toward the 0° stop until the leg of the
angle gauge is flush with the saw blade over the complete
length.
– Hold the handwheel in this position and tighten locking le-
ver 17 again.
– Tighten screw 54 again.
When the angle indicator 47 is not in line with the 0° mark of
scale 48, loosen screw 56 with a commercially available Phil-
lips screwdriver and align the angle indicator alongside the 0°
mark.
Repeat the above mentioned worksteps accordingly for the
45° bevel angle (loosening screw 57; moving the 45° stop
58). In this, the angle indicator 47 must not be misadjusted.
Parallelism of the Saw Blade to the Guide Grooves of the
Angle Stop (see figure U)
– Bring the power tool into the working position.
– Tilt the protection guard 6.x toward the rear to the stop.
Checking:
– With a pencil, mark the first visible saw tooth on the left
side that projects above the insert plate.
– Set an angle gauge to 90° and place it on the edge of the
guide groove 5.
– Move the leg of the angle gauge until it touches the marked
saw tooth, and read the clearance between saw blade and
guide groove.
– Turn the saw blade until the marked tooth projects above
the right side of the insert plate.
– Move the angle gauge alongside the guide groove to the
marked tooth.
– Measure the clearance between the saw blade and guide
groove again.
Both clearances measured must be identical.
Adjusting:
– Loosen Allen screws 59 at the front below the saw table
and Allen screws 60 at the rear below the saw table with
the supplied Allen key 21.
– Carefully move the saw blade until it is parallel to guide
groove 5.
– Retighten all screws 59 and 60 again.
Adjusting the Saw Table’s Clearance Indicator
(see figure V)
– Position the parallel guide on the right side of the saw
blade.
Move the parallel guide until the mark in the lens 27 indi-
cates 26 cm on the bottom scale.
To lock the parallel guide, press clamping handle 35 down
again.
– Loosen tensioning lever 15 and pull the table extension out
to the stop.
Checking:
On the upper scale 1, clearance indicator 51 must indicate
the identical value as the mark in lens 27 on the bottom scale
1.
Adjusting:
– Loosen screw 61 with a Phillips screwdriver and align
clearance indicator 51 alongside the 26 cm mark of the up-
per scale 1.
Adjusting the Lens of the Parallel Guide (see figure W)
– Bring the power tool into the working position.
– Tilt the protection guard 6.x toward the rear to the stop.
– Move parallel guide 10 from the right until it touches the
saw blade.
