When working complex shapes, make jigs and guides to guide
the workpiece properly and safely.
Tenoning work requires the optionaly available tenoning
carriage (see chapter 7.9)
The fence must securely be locked before starting the
machine.
Make trial cuts on a piece of scrap before working the actual
workpiece.
Support long workpieces with helping roller stands or table
extensions.
Always work one workpiece at a time.
Never operate with the guards not in place – serious risk of
injury!
Always keep your hands well clear of the rotating tool.
Never machine a workpiece if it cannot be guided properly
and safely with sufficient distance to the cutting tool.
When working complex shapes, make jigs and guides to guide
the workpiece properly and safely.
Adapt the spindle speed to the cutting tool diameter.
For the authorized use of the machine observe the

7. Setup and adjustments
General note:
Setup and adjustment work may only be carried out after
the machine is protected against accidental starting by
pulling the mains plug.
Make sure that the cutter is running clear after every setup or
adjustment done.
7.1 Spindle speed setting
Warning:
The spindle speed must be selected according to the
cutter diameter.
The cutting speed in m/sec corresponding to tool diameter
and spindle speed can be seen on the diagram (Fig 6).
The diagram also can be found on the machine.
Fig 6
At the lower spindle speeds and at smaller tool diameters an
increased risk of workpiece kickback exists.
The maximum permissible speed (rpm, /min, min
-1
) marked on
each tool may never be exceeded.
Router bits may only be operated in the highest spindle speed
(8000 rpm).
The sanding spindle may only be operated in the lowest
spindle speed (1700 rpm).
The speed is set by changing the V-belt location on the
pulleys (Fig 7).
