2. Maintenance
Check power cable for damage
Vent motor using dry compressed air
Check carbon brushes
General functional control
Carbon brush replacement:
The drill motor has carbon brushes with automatic switch-off.
The replacement should be done by an electrician, prior in
an authorised FEIN - workshop.
During the insertion of the new carbon brush observe free movement in the carbon brush holder.
New carbon brushes have to run in for 15 min in no load speed.
Only use original Fein - carbon brushes and Fein - replacement parts

3.1 General functional test
Self-start lock and magnetic foot:
Switch on the main switch (magnet) and motor switch, then connect the machine to the main power
- The motor may not start
- Magnetic foot attaches
- Check power input (0.30 A)
Switch off motor switch
- Magnetic foot remains on
- Power input has to sink to half the amount (0.15A)
Motor test:
Turn on and load motor
- Measure idle speed
- Speed is adjusted when loaded
- at approx. 1100 Watt strong speed reduction
Overload cut-out:
Heavily load or block motor
- after 10 - 16 sec. automatic cut-out ( overload protection )

3.5. Security inspection after completed repair
(directly after approx. 15 min. of breaking in)
Attention!
Basis for
the security
inspection are the
specifications of the
current
DIN VDE 0701 Part 1
(Appendix "E" for
electr. tools).
Test steps
Test type
1.
Pressing off force
1. Place KBM on smoothed steel plate (St 37).
2. Attach mains power cable to mains socket
3. Motor switch on, only then main switch on
4. Pressing off force, min 4500N (new) or min 4050N (used), measure
with force measurement tin
2.
Self-start lock
