Changing tools

Safety instructions

- For your own safety, only use original Festool
tools (see Festool catalogue).
Only saw blades that
• correspond to EN 847-1,
• have been approved for the maximum speed
of the machine (5,500 min
• have a diameter of 216 mm
can be used.
- Cracked saw blades, or saw blades which have
otherwise become deformed, may not be
used.
- High-alloy, high-speed steel (HSS) saw blades
may not be used.
- Always use tools that are appropriate for the
material being worked.
- Only use tools that have been sharpened
correctly.
To change a tool, proceed as follows:
- Lock the motor shaft by pressing the lock
button (1.1);
- Unscrew screw (1.8) using the accompanying
hexagon spanner; Note: left-hand thread.
- Remove boss flange (1.7);
- Fully retract pivot guard (1.11) and remove
saw blade (1.10);
- Clean supporting surface between saw blade
and boss flanges
- Insert new saw blade and tighten.
The running direction of the machine
(1.6) must correspond to the rotation
direction of the saw blade (1.9).
The screw (1.8) must be very tight.
- Check whether the saw blade rotates freely
before switching on the machine.
3.4 Adjusting the saw unit
The swivelling range of the saw unit can be
readjusted via screw (2.2). The swivelling range
may need to be adjusted if the diameter of the
saw blade alters during sharpening or if a new
saw blade is fitted.
The saw unit must be set to the lowest position,
as shown in Fig. 3.
The saw blade must not saw into the
aluminium base.
Procedure
- Set fences (2.4) to 0°;
- Loosen lock nut (2.1);
- Swivel the saw unit downwards until it reaches
the fence;
- Adjust the saw unit by turning screw (2.2)
(turn to the left ® saw unit is lowered;
turn to the right ® saw unit is raised);
- Tighten lock nut (2.1);

Dust extraction

When working with wood and wood-
based materials, connect the machine
to an extraction system with the
following features:
- extractor corresponding to EN 60 335-2-69,
dust class M;
- Flow rate of at least 90 m3/h;
- Vacuum of approx. 5,000 Pa.
Note: Festool extractors CTM 22 E - CTM 55 E
meet these requirements.
For connection to a Festool extractor, either
insert a 27 mm-diameter extraction hose in the
dust extraction outlet (2.3) or push a 36 mm-
diameter extraction hose over the dust
extraction outlet.
3.6 Transportation
For transportation, the saw unit should be
locked with the transport safety device (4.1)
pushed down and the pivot guard (4.3) closed.
Lift and carry the machine by the hand grip
(4.2) or by the base (4.4).
Never carry or lift the machine by the movable
pivot guard.
4 Working with the machine
4.1 Setting the cutting angle
- Offer up an adjustable square (5.1) to the
original angle (e.g. corner of room) and
tighten the wing nut (5.2);
- Open the cam levers (6.2) on both adjustable
fences;
- Transfer the original angle to the saw by
placing the adjustable square on the saw base
and then positioning both pivoted fences flush
to the adjustable square (Fig. 6)
- Close both cam levers.
4.2 Adjusting the fences
Once the rotary knobs (6.1) have been opened,
the sliding fences (6.3) can be adjusted
longitudinally.
Position the fences as close as possible to the
saw blade and close the rotary knobs.
4.3 Sawing workpieces
In unfortunate cases, the separated
workpiece parts can be caught by the
rotating saw blade and thrown back
when sawing strips. This effect occurs
especially with hard woods (oak, beech)
and is dependent on the profile of the
strip.
- Always ensure, therefore, that no persons or
objects that could be injured or damaged are
located behind the machine.
