To enjoy your model for a long time, it is necesary 
to 

service

 it regulary (i.e. after it has been in ope-

ration for approximately 30 hours). 

1. Cleaning of wheel contacts:

 Wheel cont-

acts easily get dirty on tracks which are not enti-
rely clean. Use a small brush to 

remove dirt

 from 

spots marked in fig. 4.

2. Lubrication:

  Apply 

tiny oil drops

 to spots 

marked  in  fig.  10.  Prior  to  lubrication  dismantle 
the loco body or the tender body (fig. 6). We re

-

commend using item no. 

10906, Roco oiler

. For 

lubrication the gearparts (e.g. cogwheels, worm) 
we would recommended our Roco 

special grea-

se

Seuthe steam generator no. 10 (running in digital

Very important!
Before taking into service your model these 
bearings of the coupling rods must be oiled as 
otherwise there would be the risk of bad run-
ning qualities of dramage on he locomotive (see 

fig. 10).

Operating instructions:

 Before use is advisab-

le to let the loco go around about 30 minutes for-
wards an 30 minutes backwards without load, to 
obtain an optomal circuit and best tractive power. 
The smallest radius this model should run is 

R3

 

(419,6 mm) or rather 

R2

 (358 mm) of the ROCO 

track system (model without tubes protection pis-
tons would run only if driven very carefully on 

R2

(fig. 2).

Your locomotive will run smoothly on clean tracks 
only. For this purpose we recommend using item 
no. 

46400, ROCO track cleaning van

, or item 

no. 

10002, ROCO track cleaning rubber

, for 

removing heavy dirt.

Fittings:

 Operation is possible with different 

couplings (fig. 3). We recommend using the ROCO 

close coupling.

In the enclosed accessory bag you will find small 
kits to be fitted on your locomotive. Please 

mount 

them cautiously. Attention! 

Use glue only if 

indicated (fig. 3). 

Running in digital mode:

 

First remove loco body (fig. 6). Then remove the 

jumper from the interface. Finally put the plug of 

the chip into the interface as shown in fig. 8.
