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.

3.2
Repairs
It is recommended that the repairs are carried out by NFE or an authorized dealer.
Always keep stocks of spare parts that cannot be supplied at short notice. Production losses are usually
more expensive than the costs of the spare part. Any screws that are removed must be replaced in the
same quality and design. Only use NFE original parts.
3.3
Replacing the Chisel
1. Unplug the hammer.
2. Tilt the machine backwards, so that it lies with its handle on the floor.
3. With one hand, twist the chisel lock 180o; pull the chisel out with the other hand.
4. Hold the new chisel with the locking surface facing up, and slide the chisel in.
5. Turn the chisel lock back and ensure it is fixed in place.
