Warning! 

 

All machinery can be dangerous for operating, maintenance, and repair personnel if used 
incorrectly. Owners are responsible for compliance with safety regulations during operations and 
maintenance of the safety devices supplied with the machine, and for providing suitable safety 
devices. It is strictly prohibited to remove or change the security system of the machine! 

2.3

 

Maintenance and Troubleshooting During Work 

Disconnect machine from power supply prior to performing any maintenance. Only unplug or plug in 
machine when it is turned off. 

 

Keep mains lead clear of the machine during operation; always lead the cable away from behind. 

 

The ventilation slots of the machine must be kept clear at all times. If the carbon brushes are worn, the 
brushes should be exchanged and the tool should be sent to a service center for inspection. 

 

 

 

 

Section 3 – Maintenance 

 

 

3.1

 

Maintenance Information 

 

 

 

Breakdowns caused by insufficient and unprofessional maintenance can lead to very high repair costs 
and long downtimes. Regular maintenance is essential. Operational safety and the service life of the 
machine depend on several factors, including proper maintenance. 

 

The following table contains information on schedules, inspections, and maintenance for normal 
working. The times are based on daily use. If the number of working hours shown here is not reached in 
the corresponding period, the period may be extended. However, a complete inspection must take 
place every year. 

 

Because operation conditions can vary considerably, it is not possible to state in advance how often 
checks for wear, inspections, maintenance, and repairs are necessary. A practical inspection schedule 
should be drawn up taking the operating conditions into account. Contact NFE if you require further 
assistance. 

Warning! 

 

Before beginning any repair work on the machine, make sure that it is turned off and disconnected 
from the power source.
