Setting The Riving Knife; Working With The Machine - Festool PRECISIO CS 50 EB Notice D'utilisation D'origine

• The direction of rotation on the saw blade [7-
6] must match the direction of rotation of the
machine [7-7]
• Place the saw blade on the centre of the fl ange
[8-1] and turn until the contour of the fl ange
and the saw blade hole lock.
- Firmly tighten the Fast-Fix clamp [7-4] anti-
clockwise; shift the lever [7-5]
- Swing the saw blade cover [6-2] upwards and
close the locking mechanism [6-1]
- Insert the bench insert with the rear edge fi rst
(see Fig. 9) and close the locking mechanism
[1-3].

Setting the riving knife

The spacer wedge [7-1] is to be set in such a way
that the gap to the chuck of the saw blade is 3 to
5 mm.
- Use the Allen key [6-3] to remove the screw
[7-3] and take it out together with the clamping
element [7-2],
- After both of the screws [8-3] have been opened,
the guide element [8-2] can be shifted vertically
to set the gap between the spacer wedge and
saw blade.
- After completion of the setting, fi t the spacer
wedge and clamping element again and tighten
all screws.
7.5 Guide
As shown in Fig. 3, the supplied guide can be se-
cured to all four sides of the machine. The guide
offers the following adjustment options:
• Adjustment parallel to the bench edge - open
the rotary knob [3-5].
• Adjustment vertical to the bench edge - open
the rotary knob [3-6].
• Adjustment of the sliding fence [3-1] in a lon-
gitudinal direction - open the rotary knob [3-2].
The sliding fence can be clamped onto the holder
in a low position for thin workpieces (Fig. 1), or
in a high position for thick workpieces (Fig. 3).
• Angle adjustment using the scale [3-7] - open
the rotary knob [3-3] and raise the fi xing pin
[3-4]. The rotating fi xing pin locks into place in
the most common angle positions.
This means that the guide can be used as a par-
allel guide (Fig. 1) or as a cross guide or angle
guide (Fig. 3).
Prior to all work, make sure that all rotary
knobs of the guide are tightened. The
guide may only be used in a fi xed position
and not to shift the workpiece.
7.6 Scale for cutting width
The two scales [1-5] specify the cutting width for
longitudinal cuts.
If required, the scales can be realigned after open-
ing the screws [1-4].
7.7 Mounting the splinterguard
The splinterguard [10-2] prevents breakouts on
the lower cutting edge of the workpiece.
The splinterguard can be used for all mitres, but
a separate splinterguard must be fi tted and sawn
in for each angle:
- Set saw blade to minimum cutting depth.
- Open the locking mechanism [1-3] and remove
the bench insert [1-2] upwards.
- Open the locking mechanism [6-1] and swing
the saw blade cover [6-2] down. This automati-
cally locks the tool spindle.
- Push splinterguard [10-2] from the side into the
holder [10-3] up to the stop.
- Swing the saw blade cover [6-2] upwards and
close the locking mechanism [6-1].
- Insert the bench insert with the rear edge fi rst
(see Fig. 9) and close the locking mechanism
[1-3].
- Switch on tool and slowly move the saw blade
up to the maximum cutting depth – this cuts the
splinterguard to shape.
For a optimum function the raised part [10-1] of
the splinterguard should protrude slightly (approx.
0.3 mm) above the surface of the base runner. For
this purpose the height of the holder [10-3] can
be adjusted after releasing both screws [10-4].

Working with the machine

When working with the machine, comply
with all safety instructions.
Adjust the protective hood so that it rests on the
workpiece and clamp it in this position with the
knob [1-1].
For safety reasons, NEVER work without
an upper guard [6-4] fi tted.
8.1 Bench-mounted circular saw
Use the guide as a parallel guide (Fig. 1) to guide
the workpiece. The cutting width can be set using
the scales [1-5]. Guide the workpiece into place
by hand. Use the workpiece holder [2-4] to guide
the workpiece safety past the saw blade. When not
in use, place the work-piece holder in the storage
compartment [2-1].
