MTHTrains Rail King NW-2 CALF DIESEL ENGINE User manual

RAILKING NW-2 CALF DIESEL
ENGINE
OPERATING INSTRUCTIONS
Thank you for purchasing the RailKing production of General Motor’s
NW-2 calf diesel engine. The engine’s durable ABS body and die-cast
trucks are traditionally sized for operation on any O-27 Gauge track. The
engine makes a perfect compliment for a powered RailKing NW-2 Calf
diesel engine and features an operating headlight and operating leading
coupler and is completely compatible with most 3-rail locomotives, rolling
stock and accessories.
If the locomotive is being operated with a ProtoCoupler™ equipped
powered engine, a ProtoCoupler™ kit can be ordered so that the unit can be
upgraded for use with the ProtoSound® module located in the powered unit.
Contact your authorized MTH dealer or MTH directly for details on this
option.

OIL & LUBRICATION INSTRUCTIONS
In order for the engine to perform correctly and quietly, it is important that
the chassis be lubricated before operation. Lubrication should include all
truck block bushings and pickup rollers to prevent them from squeaking.
Use light household oil and follow the lubrication points marked “L" in Fig.
1 below.
Periodically, check the locomotive wheels and pickups for dirt buildup as
this can significantly affect the engine’s ability to perform properly. Dirty
track and dirty wheels can cause both poor electrical contact as well as poor
traction, especially on elevated track sections.
HEADLIGHT REPLACEMENT
The NW-2 Calf locomotive contains one bayonet 18v headlight bulb that
is controlled by the track voltage. The headlight bulb simply plugs into its
lamp socket and can be easily removed should the bulbs expire. To remove
the bulbs, remove the cab by unscrewing the body mount screws as shown
in Figure 1. Once the cab has been removed from the chassis, gently twist
and push the bulb to unlock it from its lamp housing. Once unlocked, the
bulb will pull out of the socket. Replacement bulbs are available directly
from MTH Electric Trains.

Railking NW-2 " Calf " Unit

O-27 OPERATION
While the RailKing NW-2 Calf diesel is more than capable of operating
on O-27 curves and switches, you may find that certain light freight cars are
prone to derailing when being pulled or pushed by the RailKing NW-2 Calf
through O-27 switches. Should this occur, we suggest adding weight to the
cars making them heavier and less likely to derail.
