Maintenance works on the loco
2. Dismantle housing (Fig. 5)
Unscrew the three screws (80, 111) on the underside of the housing
and remove the housing (01) from the top.
3. Replace engine (Fig. 5)
Dismantle the housing (01), see item 2. Unclip the holder for worm gear
(48) and remove the worm gear (49) with cardan (47) from the top.
Remove the pcb (159). Unscrew the screws (50) and remove the motor
(46) with the boiler under cover (51). Unscrew the screws (52) and
remove the motor. Unsolder the wiring on the engine.
Attention: When dismantling the engine, note the wiring layout 
otherwise incorrect direction of travel.
4. Light fittings (Fig. 5)
Dismantle the housing (01), see item 2.
Bulbs front: Remove the lamp (121) from the top. Pull out the bulb (13)
and unsolder the wiring on the printed circuit board (pcb) (159).
Driver's cab bulb: Unscrew the fixing screw (21). Remove the pcb (28)
and remove the cable. Unscrew the fixing screw (19) and remove the
driver's cab (07) from the top. Pull off the cover (12) and pull the bulb
(13) and cable out of the housing.
Note: The interior lightning may be switchable by digital operating.
Switch the sliding switch at the tender. With F2 the interior
lightning can switched.
5. Maintenance work on wheelsets, gears and
coupling rods (Fig. 5)
The pic up (101) must be removed for maintenance work on the wheel­
sets (9698) or the lower gears, see item 8. Unscrew the screws (81,
110) and remove the gears cover (99).
For maintenance work on the upper gears, the housing (01) must be
removed, see item 2. Unclip the holder for worm gear (48) and remove
the worm gear (49) with cardan (47).
To unscrew the wheelsets from the coupling rods, please use the
special tool, see page 5.
The wheelset (142) can also be unclipped without dismantling
the bogie (118).
Dismantling the wheelset (93) unscrew the screw (95) and remove the
cover with spring imitation (94).
Dismantling the coupling rod (141, 142) is not recommended, as the
mechanics are complex. However, if you do dismantle the coupling
rods, please precisely note where and how each individual part was
fitted. The installation position is also given in the spare parts diagram
on page 16.
6. Replace the standard coupling shaft (Fig. 5)
Unscrew the fixing screw (113) and remove the advancing wheel (102).
Unclip the bow coupling (183) from the standard coupling shaft (103).
7. Replace the traction tyres (Fig. 5)
Unscrew the screw (68) with the special tool, see page 5. Push the
coupling rod (71 or 138) to the side and replace the traction tyres (217).
8. Replace pic up in alternating current version (Fig. 5)
Unscrew the fixing screw (110) of the pic up (101), unsolder the cable
on the slider and remove the slider.
9. Mounting smoke insert (Fig. 5)
