3.1 Selecting the blade
Caution
Damage to property can result from improper blade
selection!
The quality of the cut will be severely impaired and the
individual tools will be overloaded.
¾Use only appropriate tools.
The blade is notable for the following points:
•Moving cutter blade (upper blade) and fixed cutter blade (lower
blade) are identical in shape and can be used interchangeably
(above or below).
•All blades have four cutting edges.
•They are non-regrindable "4-way multi-edge, throw-away
cutters".
Notes
•Two different blade types can be selected for the machining
process, depending on the sheet thickness or the tensile
strength of the workpiece.
•Standard blades with a tensile strength of ≤400 N/mm² have no
special identification marking. Chromium steel blades are
marked with "Cr".

3.2 Setting the cutting clearance
The blade clearance "a" is factory-set to a sheet thickness of
2.0 mm when the machine is first delivered (see Fig. 10182, Pg.
12).
Set the following values to obtain optimum cutting results:
Sheet thickness [mm] Blade clearance [mm]
0.3-0.8 0.1
0.8-1.3 0.2
1.3-1.8 0.3
1.8-2.5 0.4
1. Push the On/Off switch several times until the moving cutter
blade has reached the lower dead point.
2. Loosen the lower blade.
3. Set the blade to the required clearance using the adjusting
screw (19).
4. Retighten the blade.
5. Tighten the adjusting screw (19) slightly.
6. Check clearance with the setting gauge.

10 Operation E518EN_04.DOC
4. Operation
4.1 Working with the TruTool S 250
¾Move the On/Off switch to the front.
1. Do not move the machine towards the workpiece until full
speed has been reached.
2. Machine/process the material.
–Move the device forward at an angle of 80 to 90° to the
sheet surface.
Requirements for the cutting of radiuses
•Do not tilt the machine.
•Proceed with a low feed rate.
Requirements for cutting near the margin
¾Cut in upside-down position, meaning that the cutting table is
facing upwards.
Note
Do not burden the device to such an extent that it comes to a
standstill.
¾Move On/Off switch to the rear.

5. Maintenance
Danger
Possible lethal danger due to electric shock!
¾Pull the plug out of the socket when carrying out tool changes
and before all maintenance work on the machine.
Caution
Damage to property possible due to blunt tools!
Overloading of the machine.
¾Check the cutting edge of the cutting tool hourly for wear.
Sharp blades provide good cutting performance and are
easier on the machine. Replace blades promptly.
Warning
Risk of possible injury due to improper repairs!
The machine does not function properly.
¾Repairs should be carried out only by a trained specialist.
Note
Check tools hourly for wear.

12 Maintenance E518EN_04.DOC
5.1 Changing the blade
Danger
Possible lethal danger due to electric shock!
¾Pull the plug out of the socket when carrying out tool changes
and before all maintenance work on the machine.
Upper and lower blades are identical. They each have 4 cutting
edges and can be used interchangeably.
In the event of insufficient cutting performance, rotate each of the
blades by 90° respectively or replace them.
1. Loosen the screw on the respective blade.
2. Rotate blade by 90°.
3. Tighten the screw.
Note
Take care to ensure that the adjusting screw (19) is up against the
lower blade.
