Only use Fein carbon brushes.
After fitting new brushes check that they move easily in their
holder. Run tool unloaded for about 15 minutes.
:
After mounting the new carbon hold ers, the heads of the screws
(4) must be covered with insulati ng va rni sh or screw locking
varnish (e.g. KP 9-15).
Check connection cable at regular intervals. To replace it, un-
screw screws (20, 21), remove cover (19), loosen screws (16) of
the clamping bridge and clamp off cable from switch (12).
No claims can be entertained for damage due to negligent main-
tenance and inadequate lubrication.
4. Dismantling
The machine should only be taken apart by an expert.
1. Unscrew screws (20, 21), remove handle cove r (19).
2.
Clamp off cable from switch (12), clamp off capacitor (17) at
motor housin g (1).
3. Clamp off carbon cable, pull carbon brushes (5) out of holder.
4. Loosen screws (75, 76), remove and dismantle outer bearing
(37) with intermediate bearing (36) . Pull forward claw shaft
(39).
5. Pull armat ure out of motor housing .
6. Pull air conducting ring (10) out of motor housing , loosen
screws (9), take out pole housing (7).
Re-assemble in reverse sequence .
5. Repair and Spare Parts
We recommend our F ei n Service Stat i ons to ca rr y out all over-
haul and repair work quickly and expertly.
Please quote Order Reference when ordering spare parts or send
in sample part.
We draw your attention to the need to carry out a high volta ge
test in accordance with your lo ca l regu lat ions (or VDE regula-
tion 0740) before taking a tool into se rvic e after any repair car-
ri ed out by your own staff.
