Maintaining and servicing your locomotive
A
n O gauge coupler (non-operating) is included with your locomotive for those who may
wish to “double-head” their trains with a second H-7 or another locomotive. Straighten out
the wire coupler pin with a pair of needle nose pliers. The coupler pin runs through the scale
coupler. Using a 1/8” hex head nut driver, loosen and remove the screw holding the scale
coupler. Remove the scale coupler. Position the O gauge coupler and secure with the previously
removed screw. Refer to Figure 8.
Store the scale coupler in a safe place for possible reassembly at a later date.
