Machine settings

Prior to any setting, maintenance or
repair, pull the mains plug!
To make setting easier, the saw unit can be
locked in the front position (Fig. 5): pull the
saw unit forwards as far as it will go and place
the switch (5.1) in the lower position.
The machine must not be used in the
front position!
6.1 Cutting depth
The cutting depth can be set steplessly (0 -
50 mm with 90° position of the saw blade) by
turning the crank handle (5.4).
6.2

Mitre

The saw blade can be pivoted between 0° and
45°:
- Open the rotary knob (5.3).
- Set the mitre using the scale (5.6) by turning
the handle (5.2).
- Close the rotary knob (5.3).
For exact fitting work (relief cutting on the
bordering), the saw blade can be pivoted 2°
beyond the two end positions. To do so, the
button (5.5) is pressed in the end position;
the saw blade can then be pivoted up to -2°
or 47°. On pivoting back, both end positions
are active once again.

Changing tools

Safety Instructions
Tension Nut (see Fig. 7 A).
After tensioning, close the handle bow.
Only tighten or loosen the Fast-Fix
Tension Nut by hand. Under no
circumstances use the handle bow with
aid of screwdrivers, pliers, or other
tools for tightening or loosening.
If the nut cannot be loosened by hand,
only use a pin-type face spanner for
support.
Never continue to use the Fast-Fix nut,
in case the handle bow is loose or
damaged.
Due to the special shank, only the saw
blades offered by Festool for this
machine may be used.
- 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
automatically locks the tool spindle
- Shift the lever (7.5) and turn clockwise (left-
hand thread) to open the Fast-Fix clamp
(7.4)
- Change the tool. In doing so, bear in mind:
• The Fast-Fix clamp (7.4), flange (8.1) and
saw blade must be clean
• 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
flange (8.1) and turn until the contour of

the flange and the saw blade hole lock.
- Firmly tighten the Fast-Fix clamp (7.4)
anticlockwise; 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
first (see Fig. 9) and close the locking
mechanism (1.3).
6.4

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, fit the spacer
wedge and clamping element again and
tighten all screws.
6.5 Guide
As shown in Fig. 3, the supplied guide can be
secured 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 fixing pin
(3.4). The rotating fixing pin locks into place
in the most common angle positions.
This means that the guide can be used as a
parallel 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 fixed position and not to shift the
workpiece.
6.6 Scale for cutting width
The two scales (1.5) specify the cutting width
for longitudinal cuts.
If required, the scales can be realigned after
opening the screws (1.4).
6.7 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 fitted and
sawn in for each angle:
