General
Please read right through these instructions,
particularly the Safety Notes on page 4.
Hornby locomotives are precision built and, if treated
with care, will give many years of good service. This
Hornby locomotive and tender are produced to super
detail standard and therefore incorporate delicate,
protruding detail and many small parts. Care should be
taken to avoid damage when handling the model
especially the valve gear, coupling rods and the small
detail parts of the locomotive and tender bodies.
This locomotive should not be operated on track
curves of less than 438mm radius, which is Hornby
2nd radius track.
The five-pole electric motor of the locomotive is
designed to be operated from a variable 12 volts,
DC power supply only. This should be obtained by
using a suitable Power Controller operated from the
normal domestic mains electricity supply.
NEVER CONNECT A LOCOMOTIVE DIRECTLY TO
THE MAINS ELECTRICITY SUPPLY.
The locomotive will normally draw a current of between
·2 and ·4 amp depending upon the track configuration
and whether or not gradients are included. There will be
a current surge on starting the locomotive.
Running Hints
If a locomotive ceases to respond normally to the
power controller, or runs badly, check that the
following are in order:
• All electrical connections are correctly made and
the wall power socket is switched “ON”.
• The power connecting clip is correctly inserted into
a suitable section of track.
• All track sections are correctly fitted together and
all fishplates (rail-joiners) are fitting tightly onto
adjoining metal rails.
• All locomotive wheels are correctly positioned on
the track rails.
• The tender drawbar pin is making contact with the
contacts on the locomotive drawbar and the upper
contacts of the drawbar are making contact with
the drawbar pin plate of the tender.
• The direction control switch on the train controller
is set to operate in one direction or the other, and
not in the central “OFF” position.
Routine Maintenance
Track Cleaning – In normal use, model railway layouts
will eventually accumulate a blackish deposit on the
running surfaces of the rails, and some of this will be
transferred onto the locomotive’s pick-up wheels.
The 12 volt DC supply is collected from the track
through the wheels on one side of the locomotive and
returned through the wheels on the other side. If the
deposit is allowed to build up, it will have the following
adverse effects:
• The driving wheels will not be able to achieve
maximum traction
• There will be a reduction in the power reaching the
locomotive motor
It is therefore essential that the track and wheels are
kept clean. This can be done by wiping the surfaces
with a clean, non-fluffy cloth. More stubborn deposits
can be removed by using the Hornby Track Cleaning
Rubber, reference R8087, which can be obtained from
Hornby Service Dealers.
Motor – The locomotive is fitted with a sealed, long-
life, 5-pole motor which requires no maintenance.
After a considerable amount of use the motor may
require replacement and it is recommended that this
work be carried out by a Hornby Service Dealer.
Chassis – The locomotive chassis may, from time to
time, pick up fluff, fabric fibres and pet hairs which can
become entangled in the gears and around axles. For
this reason, it is not advisable to run the locomotive on
track which is laid on a carpet. It is important to check
regularly and remove any such debris with the aid of
small tweezers.
Lubrication – Although the locomotive was lubricated
during manufacture, the lubricant can sometimes dry
out in storage. Lubrication should be carried out at
approximately 6-monthly intervals, or every 100 hours
of running. Instructions for carrying out lubrication
procedures are given in section 1 on page 2.
Locomotive Bodywork – The locomotive and tender
bodies are overall spray painted and the rest of the
decoration is applied by a printed process, not
transfers.

Television Suppression
Your Hornby locomotive incorporates radio and television interference suppressors. Should interference be
experienced despite these precautions, it may be due to close proximity of the model railway layout to receivers,
aerials, or their “downlines”. In this case, move the layout further away from aerials and receivers.
It is most important that track and wheels be kept absolutely clean.
Spare Parts and Service
Spare parts packs can be obtained from Hornby Service Dealers who are also able to offer a repair service.
IMPORTANT
• Please remove the locomotive and tender from the packaging carefully.
• This locomotive is made to exacting fine scale standards and therefore necessarily
incorporates small, delicate, protruding parts – handle with care.
• Before using the model, read through the Operating and Maintenance Instructions in
this leaflet.
• This locomotive is not suitable for children under
3 years of age because of small parts which can
present a choking hazard. Some components have
functional sharp edges – handle with care.
• This locomotive is intended for indoor use only.
• The transformer is not a toy. It is a “Transformer
for Toys”. Before use, check that the transformer
is the correct voltage for your mains electricity
supply. This locomotive is only to be used with the
recommended transformer. The transformer
should be examined regularly for damage to the
casing, plug pins and cables. In the event of such
damage, the set should not be used until the
transformer is replaced with a new Hornby
recommended unit. Never attempt to open
the transformer yourself.
• This locomotive must not be connected to more
than the recommended number of power
supplies. The output terminals of the transformer
must not be connected directly, or indirectly, to
the output of any other AC circuit derived from a
transformer or mains power supply.
• Before cleaning any part, disconnect the
transformer from the mains electricity supply.
Do not use liquid for cleaning.

Lubrication
IMPORTANT – Only apply small single drops of light machine oil to the places indicated in red.
This is best achieved by making a simple oil “dropper” as illustrated in Fig.1. Insert a straightened
paper clip into a cork and use a bottle cap as a container for the oil. A small drop of oil can then be
picked up by the dropper and applied in exactly the right place. Immediately wipe off any excess
oil, especially from the locomotive and tender bodies. Only lubricate moving parts.
Apply one drop of oil to each of the points indicated
in red in Fig.2, on both sides of the locomotive.
Apply one drop of oil to each of the axle bearings indicated in red.
To remove the locomotive body
Turn the locomotive upside down and remove vac tank moulding (if fitted), by carefully inserting a small flat-blade screwdriver and using a gentle side to side action to loosen,
lever off (Fig.5). Remove screws (Figs.5a and 6). Carefully ease chassis down from the body. (The side connection pipes will detach from the body).

Accessories
If running the locomotive, EITHER the coupling
bar OR the articulated coupling and pipes
included in the accessory bag can be fitted.
The coupling bar AND articulated coupling
and pipes can all be fitted ONLY if the
locomotive is used for static display.
Vacuum pipes supplied will vary according to
the variant of M7 locomotive. For example,
most SR locomotives will have one vacuum
pipe fitted in position 2, front and rear.

Note: The vac tank moulding will need
to be removed if a coupling is to be fitted.

Note: When re-assembling, replace the vac tank moulding using thumb to
press back into place (Fig.8), unless a coupling is to be fitted instead. Please
make sure that the connection pipes are re-connected on both sides (Fig.9).
