Operating Instructions.
Guide the power tool toward the workpiece only
when switched on. Otherwise, the workpiece and
application tools may be damaged.
During machining, the guide roller must always be in
contact with the workpiece.
Firstly remove the switched-on power tool from
the workpiece and then switch it off. Otherwise,
the workpiece and application tools may be damaged.
If power tool vibrations increase significantly,
check the setting parameters for the respective
application material and the condition of the application
tool.
Danger of injury from chippings.
Always keep your hands, clothing
etc. away from chippings. Do not attempt to remove
the application tool when still rotating. This can lead to
serious injuries.
Danger of injury from sharp edges
of the milling head.
Do not touch
the sharp edges of the milling head.
Danger of burning. The application
tool can become hot during opera-
tion. Allow the application tool to cool down:
– after placing the power tool down
– prior to tool changing.
Rotate or turn around the eightfold heads as required.
Please note that milling head, guide rollers and indexa-
ble inserts may vary depending on the application. Only
use accessories approved for the application.
When machining bevels and radii, pay attention that the
correct speed stage is set dependent of the material.
Various materials can be subject to hardening at the
edges due to heating, plasma or laser cutting. This can
lead to very high deviations from the specified refer-
ence values.
Setting the bevel height (see page 9/10)
Use indexable inserts for bevels, which are available as
accessories. Set the bevel height “a” via the setting
dimension at the guide plate. Make a test run. As the
scale has a tolerance of approx. ± 1 mm (approx.
1/32''), readjustment may be necessary. Readjustment
is made using the second scale (numbers 1 to 15) on the
guide plate. The guide plate is adjusted by 0.1 mm
(1/254'') per digit. The maximum, material-dependent
setting dimension and the recommended speed stage
can be found in the following two tables.
Setting the radius dimension (see page 10)
Use indexable inserts for radii, which are available as
accessories. The setting dimension of the guide plate
must be adapted to the respective radius. For setting
dimension values, please refer to the respective acces-
sory. For the material-dependent speed stage, please
refer to the two tables below.
The specified values are empirical values and can-
not be guaranteed.
Repair and customer service.
When working metal under extreme oper-
ating conditions, it is possible for conductive
dust to settle in the interior of the power
tool. The total insulation of the power tool can be
impaired. Blow out the interior of the power tool via
the ventilation slots frequently with dry and oil-free
compressed air, and connect a residual current device
(RCD) on the line side.
Clean and lubricate the thread of the height adjustment
on the guide plate as required. Unscrew the guide plate
and turn out the guide-plate holder. Clean the thread
on both sides and apply oil.
Products that have come into contact with asbestos
may not be sent in for repair. Dispose of products con-
taminated with asbestos according to the applicable
country-specific regulations for such disposal.
