Working Instructions; Preventive Maintenance - Bevel Tools Bevel Mite EBI-06 Premium Mode D'emploi

3.3 Working instructions

• To achieve an optimum Bevel result, move Bevel 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
tool.
• 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 3mm with a maximum Power-on time of 50%.

4.1 Preventive maintenance

• To work effectively and surely keep the machine and the ventilation slots clean at all times.
• 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.
4.1.1 Changing the carbon brushes
The Automatic-Stop feature protects the machine from defects due to excessively consumed carbon
brushes. The machine is equipped with two carbon brushes, i.e. one is installed in each handle half.
The carbon brushes must be changed as follows:
• Unscrew four screws and remove the handle halves.
• Lift spring with screwdriver and remove brush. Install new brushes. Clean carbon brush holders,
making absolutely sure not to change the arrangement of the elements of the carbon brush
assembly.
• Fit handle halves and fasten with four screws.
• Repeat this change on the opposite side, making absolutely sure to avoid both handle halves from
being opened at the same time.
