3.1.2 Emission values at place of work
AP emission - idling
AP emission - at work
Ÿ The sound level at the place of work can exceed
85 dB(A), in which case soundproofing measures
(hearing protection) are required for the operator.
Ÿ The values quoted are emission values and thus
do not necessarily represent true work place
values. Although there is a correlation between
emission and immission levels, it is impossible
to reliably say whether additional safety measures
will be necessary or not. Factors which could
affect the immission levels actually present at the
place of work include the duration of the exposure,
the peculiarities of the work room, other sources
of noise, etc., e.g. the number of machines and
other neighbouring processes. However, this
information should allow the user to make a better
estimation of the dangers and risks.

3.2 Residual risks

Despite the observance of all relevant construction
regulations, risks may still arise from the use of the
PRECISIO, for example from:
Ÿ flying workpiece parts
Ÿ flying parts of damaged tools
Ÿ wood dust emission
Ÿ noise emission

Erecting the saw

Ÿ After removing the machine from its transport
packaging unfold the foldaway legs (1.1) and
screw in place using the grip knobs at the joints.
Now place the machine on an even, firm base.
Ÿ Screw the loose grip knob (2.6) enclosed with the
machine into the pull bar in an anti-clockwise
direction. Attention! left-hand thread.
Ÿ On delivery the saw is locked in its idle position.
Turn the knob (2.6) to the left to release the lock
so that the saw can be pulled forwards.
Ÿ The saw is now locked in its foremost position
(setting-up position) by pressing the catch lever
(1.7) down and can be adjusted to a maximum
cutting depth by turning the crank (1.8) to the right.
Ÿ The height of the built-in riving knife (1.6) can be
adjusted and this has an upper and lower locked
position. The lower locked position (state on
delivery) is necessary for concealed cuts. The
riving knife must be in its upper locked position
for all other cuts. The riving knife should thus be
brought into its upper position by pulling upwards
firmly (7.2) In this position, the enclosed upper saw
cover is screwed onto the riving knife with a screw.
Ÿ Turn the knob (2.6) to the left to release the saw
lock, the saw now slides into the idle position on
its own.
77 dB(A) Ÿ The return speed can be adjusted by altering the
90 dB(A) damping at the setting screw (3.5).
Ÿ The end cap (1.9) can be rotated to adjust the
height of the front right foot to ensure that the saw
stands firmly on the ground without wobbling.
5 Basic comments on working with the
saw
The saw can be used in two different ways:
Ÿ as an under-table pulling-cut saw (section 5.1),
where the workpiece is stationary and the saw is
moved during cutting.
Ÿ as a bench-mounted circular saw (section 5.2),
where the saw is stationary and the workpiece is
moved.
5.1 As an under-table, pulling-cut saw
Ÿ Turn the knob (2.6) to the left to release the saw
lock and pull saw forwards with this knob. The
saw can be locked in the foremost position by
pressing the catch lever (1.7) down so that the
controls to adjust the saw (depth of cut, angle
adjustment, speed) are easily accessible. Turn
the knob (2.6) to the left to release the lock again.
Ÿ Fit the mitre fence accordingly (see section 9) so
that the workpiece can be held firmly on the saw
table.
5.2 As a bench-mounted circular saw
Ÿ First pull the saw fully forwards. Now let it slide
gently back. After a few mm press the catch lever
(1.7) down. During further backward movement
the catch lever engages in the pull bar and locks
the saw in the centre of the table (bench-mounted
saw position).

Electrical connection and starting

The PRECISIO is a device from protective class II.
The mains voltage must correspond to the voltage
specified on the ratings plate.
We recommend a 16 A fuse due to the high load
on the motor. The mains cable can be wound around
the clips (1.3) when the machine is not in use or for
transportation purposes.
Switch the machine on by pressing the green button
(1.2) The red button is the OFF button.
The switch has a no-voltage circuit breaker.
After a power failure the machine does not restart
automatically when power is restored.
The green ON button has to be pressed.
A lockable switch guard is available as an
accessory as protection against unauthorised use
(order no. 488 065).
