3.2 Bevel heads

Use only bevel heads whose admissible maximum speed is equal to or higher than the no load speed of the machine.
Use only clean tools!
i
3.2.1 Changing a bevel head
• Disconnect from power supply.
• Turn the flange head to its maximum depth.
• Lock spindle by pressing the orange locking button on the back of the gearbox.
• Use the hex wrench (5 mm) to unscrew the guide bearing.
• Take the bevel head off.
i 3.2.2 Mounting a bevel head
• Before mounting the bevel head, clean the surface of the adapter and bevel head.
• Check the guide bearing, it should run smoothly, a guide bearing that doesn't run smoothly will damage the bevel
head and can lead to a broken bevel head.
• Place bevel head on the adapter, the pin on the adapter should easily fit into the pinhole in the bevel head.
• Lock spindle by pressing the orange locking button on the back of the gearbox. Use the hex wrench (5 mm) to
tighten the guide bearing.
• Check if the bevel head runs smoothly and true, not true running bevel heads must be replaced immediately.
Check bevel tool before use. The bevel head must be correctly mounted and must rotate freely. Perform a trial run
over a period of min. 30 seconds without load. Do not use bevel heads which are damaged, which do not run true or
which vibrate!

3.3 Operating instructions

!
• To achieve an optimum bevel result, move beveling tool uniformly with light pressure.
• The electronic constant control maintains the speed nearly constant during idling and work under load and assures a
uniform result.
• Excessive pressure lessens the working capability of the machine, as well as the life of the bevel head.
• The machine is equipped with an electronic control and integrated overload protection.
• If the machine is overloaded, the speed will drop drastically. Immediately take the load off the machine and allow
to run for a short time without load.
• Maximum depth per cut, on steel, no more than 4 mm with a maximum power-on time of 50%.

4.1 Preventive maintenance

• To work effectively and safely, keep the machine and the ventilation slots clean at all times.
• Keep the thread and grooves on the bearing housing and the internal thread of the flange head clean to prevent
jamming and premature failure of the ball screws.
• After approx. 200 operating hours check carbon brushes and replace if necessary. Clean motor housing and replenish
grease filling in gearbox housing. When the brushes are spent, the machine will stop automatically.
• To maintain the protective insulation the machine must be subjected to a technical safety inspection. This work
must be done exclusively by a specialized electrical workshop.
• When working on metal under extreme working conditions, conductive dust deposits can occur inside the machine,
thereby impairing the protective insulation of the machine. In such cases the use of a stationary vacuuming system,
frequent blowing out of the ventilation slots and protection by a fault current protection switch are advised.
