Service And Maintenance; Controllable Functions - LGB 21670 Manual De Instrucciones

• Do not use to clean the nickel plated LGB rails.
• The cleaning motor operates only when the 21670 is moving forward. This makes it
easy to clean dead-end sections, like sidings.
• The 21670 will not clean wet or oily rails.
• Track Cleaning Wheels (67267) are available from authorized LGB retailers. The pa-
ckage includes cleaning rings, inner wheel flanges and outer wheel discs. Always
replace the flanges and disks together with the cleaning rings.
Attention! When cleaning the tracks, carbon dust and other debris accumulates
around the track. This dust and debris can stain carpet and other materials.
Track Cleaning
Analog operation (conventional transformer and throttle):
• Set your layout speed control to zero.
• Place the 21670 on the track.
• Set the power control switch to Position 2 (see Operating Modes).
• Set the 21670 on-board speed control to a middle position (Fig. 3).
• Set your layout speed control to the highest forward position.
The 21670 will move forward with a medium speed, and the cleaning wheels will
clean the rails.
Hint:
• The speed of the track cleaning loco is adjusted with the on-board speed control.
The layout speed control (Fig. 3) always should be set to the highest speed, so the
cleaning wheels are turning at maximum speed.
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 automati-
cally 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.
