HE information containedin this book has been
arranged to facilitate reference, by condensing
all essential driving and upkeep instructions in
the first two chapters. Numerous referencesto other
parts are provided, whereby any particular instruction
may be amplified
if required.
Subsequentchapters include explanations of the
working of the various units or componentsof the
chassis,
and include detailed directions for lubrication
and maintenance.
Owners and drivers should, therefore, familiarise
themselves
with the first two chapters
in orderto operate
the car successfully,
referring to the remainder of the
bookat leisure,
or if necessarv.
A set of specialspanners
and tools is supplied with
the chassis. It is most desirablethat these should be
used
wheneffecting
any adjustment,as otherwise
vital
parts may be seriouslydamaged.
It is strongl,y
recovwneniled
that this boohbecareful'ly
studied,
and theinstructions
faithfully followed,to ensure
the greatest
satisfaction.

THE
SECRET
OF SUCCESSFUL
RUNNING
Beforea Bentley car is sold,it is very carefully
testedand adjusted
by experts. It will run bestif
no attempt is made to interfere unnecessarily
with
adjustments.
An ownerwould do well to instruct his driver as
follows:-
Lubricate effectively, in strict accordance
with
the advice given in this book, and do not neglect
ony part.
Inspect all parts regularly, but take carenot to
alter any adjustmentsunlessreally necessary.

Starting the Engine,
Switch on the ignition by turning master and ignition switches
on the instrument board to On.
Themaster
switchcontrolsall the electrical
system,excepting
the
electricclock,inspectionand roof lamps,the latter beingleft always
availablefor convenience
when enteringthe car in the dark.
A smallred warninglight on the instrument boardwill beillumi-
nated
whentheignitionis switched
on,but will beextinguished
when
the engine
speedis sufficient
to causethecut-out contacts
to close.
Ensure
that the gear lever on the steeringcolumnis in neutral,
quadrantgearposition "N", as it is only in this positionthat the
starter switch is operable.
Beforestarting the car in temperatures
aboae
freezingpoint,f,rst
defress
theaccel'erator
pedal,
slightl,yand tken al,loait to return t6 its
norrnal
position. This permits the throttle stop on the carburetterto
re-position
itself correctly according
to enginetemperature.
-
Under v_erycold conditions, in temperaturesof below freezing
p-oint,it will be necessaly_
to depressthe acceleratorpedal slightlR
about a quarter of its full travel, and hold it depressed
while the
starter button is being operated. Immediately the enginefires, the
accelerator
pedal should be released.
Depress
the starter button firmly, an appreciable pausemust be
made
between
theoperatign;
of switching
on theignition and,
depressing
tke starterbutton,especially
uhen making a startfrom cold.
-This ii
necessary
in order to give the pumpstime to fill the float chambers
of the carburetters.
Use of Starting Handle.
, It,is imperatiae
uhen starting the cngine
with thestarting hand,l,e,
that tkegearleaer
