Multi-Train System:
• Place the 21670 on the track.
• Select the loco address and run the loco forward at
moderate speed.
• Press the F1 function button. The cleaning wheels turn
and clean the rails. To stop the cleaning wheels, press
the F1 function button again.
Hint:
• A safety feature turns off the cleaning motor when the
MTS control is set to “0“.
Cleaning speed
Set the built-in speed control (for analog operation) or the
MTS control (for MTS operation) depending on the condition
of the rails:
• If the rails are slightly dirty, run the loco faster.
• If the rails are moderately dirty, run the loco slower. The
cleaning wheels will clean more contamination.
• If the rails are extremely dirty, do not try to remove all
the dirt at once. Select a medium speed and repeat the
cleaning process several times until the rails are clean.
Track Cleaning Hints
• When the 21670 is operated for the first time or with new
cleaning rings, it may not run smoothly.
• The cleaning motor is equipped with a thermal overload
switch. If the motor is overloaded, the switch will turn off
the cleaning motor. The switch will automatically reset
after a few minutes. To avoid overloading, operate the
loco at a higher speed.
Attention!
Replace the cleaning wheels before the gray
cleaning rings are worn to the level of the outer wheel disks
(see Replacing the cleaning wheels). If the rings are worn
to the level of the outer wheel disks, the disks can damage
the track.
Attention!
Do not run the 21670 unattended. If it derails, the
cleaning wheels may continue to rotate and damage the
track.
