TAKING
THE
SCOOTER
ON
THE
ROAD
Filling
up
with Petrol and
Oil.-
The pelto[ tank
is
mounted
all
a
special frame brackct andisseen when the dual seatisraised on its
hinges
(see Fig.
7).
Its capacity
is
I!
gallons. (See special instruc-
tions on filling up
Wilh
pelroil mixture for the single cylinder two·
stroke model on page
33).
The oil sump capacity,
2,
pints,issituated under the engine and
the filler
cap
(8)
Fig. 7,ison topofthe rocker box cover. The dip-
stick indicates lhe oil level.
For
recommended oils see page
II.
The gearbox and transmission
will
in
most cases have been filled
to the
correct
level
by the dealer before delivery, but
if
this
is
in
doubt access to the liller plug for the former can
be
obtained by
removing the right-hand side gauze cover (Fig. 8). The filler cap
and the level plug willihen
be seen
at
(A)
nnd (8) Fig.9.The primary
drive filler plug (two-stroke model only) aod the rear drive
flUer
and
level
plugs areseeninFig.10at
(A), (0) lind (e) respectively. Recom-
mended oils
:.Ire
listed on page JI.(See also Fig.
II).
To Slarl the
Engioe.-
Turn on the petrol, depress tickler for a
moment and pull out the choke
(see Fig.
5).
Place tbe gearinoeutral
by
moving lhe gearchaoge
P'o:dal
forward once,
or
more if necessary,
until bottom
gearisengaged. Then operate the neutral finder pedal
(Fig.
3)
once. This
will
bring the gear iota the neutral position
between
first
and second genrs.
Turn the ignition switch to the
lGN
or I position (according to
model) and on models with electric starting pull the knob smartly.
This
"ill
cause the engine to rOlate and it should
fireatonce. Release
the slarter knob immediately the engine
fires.
In
the case
of
models not provided with an electric starter the
Slarter pedal should
be operated instead. Depress the pedal gently
until lhe
ratchet engages, and then push down sharply.
For
starting without a battery
or
if the batteryisdischarged see
instructions on
page 29, or page
35
(according to model).
When the engine
is
running Ihe choke should be pushedinas soon
as possible.
Norn:-Do
not use the choke when startingifthe engineiswarm.
To
Engage
Low
Gear and Move
Ofr.-Pull
the clutch lever
up
to
the handlebar, thus disengaging the clutch, and engage low gear by
moving the gearchangc pedal forwards (see Fig.
3),
releasing the
pedal
as soon as the gearisfelt to go in. Then accelerate the engine
slightly by means
of
the twist griP. and gently release the clutch lever.
The scooter
will
move forward smoothly and accelerate as the throttle
is
opened further.
7
www.triumphtigress.com
To Change
Up.-As
soon as the scooter is well under way,
whkh
on
level ground should amount to no more than a yard
or
two,
second
gear should be engaged by moving the gearchange pedal
to
the rear and releasing it again,
at
the same time momentarily dis-
engaging the clutch
by
meum
of
the lever on the left handlebar.
Changing
to
third gear and finally to top are elTected in precisely
the same manner.
To Change
Down.-Declutch
and simultaneously move the gear·
change pedal forward releasing both as soon
as
the gearisfelttogo in.
This operation
is
carried out
in
the same manner when changing
from top to third, third
to
second,
Rnd
second
lO
first.
The
Art
of
Smooth Gear
Cbanging.-
The
gearbox is
of
a very
robust construction. and the gearchange mechanism is positive in
action
so
Ihat gearchanges will
be
made wilhout fail even by a novice
if
he follows the inSlructions given above. but wilh practice and the
application
of
a littleskill
to the manipulationofthe variouscontrols
a smooth and silent gcarehangc can
be
achieved, which will give
satisfaction
10
the
rider and bring credit to the scooter, for there
is
nothing more gratifyingtothe experienced rider than the knowledge
that he has the ability to make a smooth
and
silent gearchange
at
aU
times, and that his scooter will respond in this matter
to
his
expert manipulation
of
the controls.
For
example, when changing up the rider should not only select
a suitable speed
al
which to perform the operation, but he should
also time his gearchanges in such a way
that
engine speeds and the
speeds
of
the moving parts in the gearbox should be allowed to
coincide as far as possible. This laHer requirement
is
mel usually
by momentarily closing the throtlle before
dcclutching for
the
gear-
cbange. thus removing the
power drive from the gearbox and lening
it slow doy,,"
to
the lower speedatwhicbitwill operate in the higher
gear about
to
be engaged. As soon as the gearisengaged and the
clutch
is
released the throttle should
be
opened again smartly. but
without a sudden jerk.
If
gcarchanges are made in this manner. and
mis applies
to
all changes up from low gear upwards. then the opera·
tion can be performed silenlly and smoothly with only an alteration
in
me
engine note to indicate that the change has been made.
When changing to a low gear
it
will be seen from a consideration
of
the conditions described above that the engine speed has to be
increased relative to that
of
the scooter and the throllle should not
therefore
be
closed while making the change. As soon as the clutch
is
released the engine
will
automatically speed
up
and if the change
is
made smarlly and confidently, the lower gear selected
",':ill
slide
into engagement qujetly at the correct engine
speed.

To
the novice the above instructions may sound somewhat compli-
catedalthough they are in faet
ex-trem
ly simple,
and
ridersofaverage
potential skill and ability rapidly acquire the correct knack
in
a very
short mileage after first acquaintance with the scooter, so
that
neat
and
precise gearchanging quickly becomes second nature.
Itisemphasized
that
it i de irable to acquire the ability to operate
a gearchange mechanism smoothly
not
only from the view-point
of
personal satisfaction,
but
also because silent and shock free changes
naturally impose less strain on the rapidly moving parts, with the
result that wear and
tear
are reduced to the absolute minimum, and
the scooter
will continue to operate in a .tateofmechanical perfec-
tion throughout its
useFul
life.
To Stop the
Engine.-Select
neutral gear close the tbrottJe, and
turn the ignition switch to the
"OFF"
position.
LUBRICATION
SYSTEM
(Twin-Cylinder model)
The
Engine.-The
engine is lubricated
by
a circulating system in
which
oil
is
drawn from a
rc
crvoir upplied under pressure to
various working
part
of
Lhe
engine, and here·after returned to
the
reservoir for Te-circulation.
The
system operates
in
the following
manner:-
The reservoir take
the
fonn
of
a ump bolted to the underside
of
the crankcac,and
a supply pipc draws
oil
from this sump through
a filter and carries it to the oil pump.
This pump, whichisof
the
plunger type
is
driven
by
a connecting rod
by
an eccentric on the
camshaft,
and
draws the oil through the supply pipe referred to
above, and delivers
it
under pressure through drilled passages, first
to the offside crankshaft bearing
and
then through oil-ways drilled
in the crankshaftitselfto the connecting rod big-cnd bearings. After
Lubricating the e bearings, the oil emerges into the crankcase
in a
finely divided condition whichischurned
up
into mist by the rapidly
rotating parts and spreads over the entire internal structure
of
the
engine, thus providing lubrication for the connecting
rod
small-ends,
the pistons, the cylinder bores, the nearside crankshaft bearing,
which
is
a ballrace,
and
the timing gear.
The
oil then condenses
into liquid form, and returns by gravity through a filter tray to the
sump. A by-pas i
al
0 taken from the
pump
supply, and this is
taken first to the camshaft and then through a metering hole in the
ofIside bearing to an external pipe which feeds it to the overhead
rocker spindles.
It
then drains back from the rocker box lubric-
ating both primary drive and timing gears before returning
to
the
sump.
The
Iubrication system
is
thus self-contained and
[ully
automatic
in
action.
It
is
quite foolproofand calls for no attention on the
part
of
the rider
apart
from the obvious precaution
of
checking the oil
in
the
sump
at
regular intervals by inspecting the dipstick (Fig. 7)
to ascertain
that
the correct level is maintained.
9
www.triumphtigress.com
As
seen
in
the maintenance instructions it
is
recommended that
the sump should be drained and refilled with fresh
oil
cvery 2,000
miles. The sump should be removed for cleaning every
6,()(X)
miles
and this involves raising the scooter on a trestle or a couple
of
suit-
able boxes so that the twelve scrcws by means
of
which itisbolted
to the crankcase may
be
taken out. When thisisdone the filter tray
and also the supply filter should
be
removed and thoroughly cleaned
by
rinsinginparaffin.
Primary
Drjvc.-This
consists
ora
clutch on the engine shaft coupled
to tbe engine shaft pinion which drives a larger pinion on the gearbox mainshaft, thus giving the primary reduction.
The case forms part
of
the engine lubrication system on the lwin-
cylinder models and after the initial filling there
will
be no need for
furtber attention.
With the single-cylinder model the primary drive
oil
level should
be checked periodically (sec page 4, Fig.
10).
Gearbox.-
The gearbox has an entirely independent
oil
system which
is
supplied through a filling orifice on
top
or
the box (see Fig. 9).
There
is
also a plug which determines the correct level.
It
is
so
arranged that tbe larger
of
mainshaft gears dip into it and piek up
sufficient
oil
to churn it into mist for distribution throughout the
entire box, including the gearchange mechanism. The only
main·
tenance necessaryisto check the
levelatintervalsasdescribed under
"Routine
Maintenance", and to drain and refill after prolonged
mileages
by
which time the lubricating qualities
of
the
oil
may have
become somewhat impaired.
Rear
Drh·e.-The
rear drive, which
is
by chain, operates in a cast
aluminium oilbath chaincase, and it
is
provided with an independent
oil supply which is controlled
at
the correct
level
by the filler plug
seen
in
Fig.
10.
The
level
plug is
so
positioned that it ensures the
correct quantity
of
oil being poured in.
The rear drive lubrication system requires no attention beyond a
periodical check
of
the
oj]
level, together with draining and re-filling
when necessary as described under "Routine Maintenance".
Other
Parts.-Grease
gun lubrication is provided for the brake cam
spindles, the front fork, the nearside rear suspension swinging arm,
and the foot gearchange pivot as outlined on page
11.
Other working parts which require lubrication arc packed with
grease during assembly and this should suffice until such time that
a major overhaul becomes necessary.
