intermountain AC-12 - DC Operation; Basic Analog Mode Operation

Preparing the InterMountain AC-8/10/11/12 Steam Locomotive for Operation:
Every InterMountain AC-8/10/11/12 Steam Locomotive is factory tested prior to release. The InterMountain
AC-8/10/11/12 Steam Locomotive is factory lubricated on all internal driveline components. The external
driveline components are not factory lubricated to protect the finished model in its presentation packaging.
Once initial set-up and test run is complete the following lubrication is required prior to normal
operation of the locomotive:
•Using high quality plastic compatible lubricating oil, carefully (but sparingly) lubricate all moving parts of
the external side rod assemblies. InterMountain Railway recommends Labelle
®
108 - Synthetic Oil Multi-
Purpose Light Weight.
•Lubricating the drive axles at their bearings is also recommended (see image below).
•Avoid and remove any excess oil prior to normal operation of the locomotive.

DC (Basic Analog Mode) Operation:
Operating the Locomotive with a standard N Scale Compatible (DC Analog) power pack:
•Set the DC Power pack direction control switch to forward.
•Set the DC Power pack throttle to Zero/Stop position.
•Turn on the N Scale Compatible DC Power pack.
•To Accelerate: Advance the throttle control slowly until the locomotive moves forward. Adjust the throttle as
required to achieve the desired speed.
•To Decelerate: Reduce the throttle control slowly. Adjust the throttle as required to achieve the desired speed.
•To Stop: Reduce the throttle control slowly to the Zero/Stop position.
•To Reverse or Change Direction: With the throttle in the Zero/Stop position, change the power pack direction
control switch to reverse or opposite position. Then accelerate, decelerate, and stop as described above.
Important Notes:
•NEVER Reverse or Change direction while the locomotive is moving as this may damage the driveline
components.
•Avoid rapid throttle changes and abrupt stops to reduce excessive strain on driveline components.
