PREMIER AUXILIARY TENDER

OPERATING INSTRUCTIONS

Thank you for purchasing the MTH Electric Trains N&W Auxiliary Water
Tender. This die-cast O-Scale replica of the water tender makes a perfect

complement for any owner of a M.T.H. O-Scale N&W steam locomotive and
includes the necessary hardware to configure the Proto-Sound® and

Proto-Coupler® system found in the MTH N&W steam locomotives to
operate the water tender’s own Proto-Coupler.

Configuring the N&W Tender to operate with
the N&W Auxiliary Water Tender

Proto-Coupler®.

For the Auxiliary Water tender’s Proto-Coupler to function, it must be
electrically connected to your N&W Coal Tender. To accomplish this,
there is a preinstalled wire harness inside the Coal Tender that will
connect the two tenders together electrically.

1. First start by using a Phillips screwdriver to remove the 6 chassis
screws securing the Coal Tender’s body to its chassis. Refer to your
N&W Steam Locomotive instruction manual for their specific location.

2. Upon removing the tender body, identify the wire harness, which
should be secured inside the chassis near the Coal Tender’s speaker cone.
Refer to figure 1 and follow how the wire harness is fed through the hole
at the rear of the floor/chassis. Be sure not to bind or twist the harness

during this process.

3. Reinstall the tender body with the six securing screws.

4. You may now select protocoupler operation of either tender by the
switch selection underneath the N&W Coal Tender. Refer to your N&W

Steam Locomotive instruction manual for specific location of the switch.
Proto-Coupler operation is selected by sliding the switch towards the rear
of the Coal Tender for Auxiliary tender Proto-Coupler operation or
forward for coal tender Proto-Coupler operation.

5. After Proto-Coupler operation selection, connect the wire harness plug
from the coal tender to the wire harness connector jack on the Auxilary
tender.

You are now ready to enjoy your new N&W Auxiliary Water tender with
your N&W Steam Locomotive.
