Starting The Cold Engine During The Summer Period; Braking And Stopping; Maintenance Of Vehicle; Maintenance And Adjustment - JAWA babetta 28 Servicing Instructions

Starting the cold engine during the summer
period
a) start on stand: this is made in such a way the
moped is put on the stand, the oir closure push
button arranged on the carburettor is depressed,
the decompressor lever is depressed the gas grip
is rotated to ½ of gas grip rotation range, the pedal
is put.abt, 30º from the perpendicular position in
the direction forward, the pedal is kicked suddenly
and before the final kicking the pedal into lower
dead posltion (when the engine has the sufficient
speed) the decompressor lever is released. The
engine start to work Repeat this if required. After
starting it is necessary to let the engine to warm
up, after warming up rotate the gas grip up to
contact due to what the air closure valve of
carburetor is opened. By rotating the gas grip
backward the engine works on idle run and it ls
ready for the drive. The vehicle is put from the
stand on the wheels and by releasing the gas the
start is effected.
b) Start by kicking: The vehicle is put on the
wheels, the air closure push button on the
carburettor is depressed, the decompressor lever
is.depressed, the gas grip as in the point a) is
rotated. The vehicle is put in motion due to kicking
and when the sufficient velocity is obtained the
decompressor lever is released, the motor starts
and by releasing the gas its velocity is increased. If
required during the drive, especially when drive
uphill the engine may be aided by kicking the
pedal.

Start of warm engine (after shorter drive
interuption).
The methods mentioned under a) and b) may be
used. It is not necessary to depress the air closure
on the carburettor.
Start of engine during the cold weather (in the
winter)
When the temperature of atmosphere sinks below
0º C the start is to be effected as follows:
Start is made as under point a) with that difference
before the start the pedal is to be kicked several
times to loosen the individual mechanisms which
stiffen due to the cold. One can help out by
depressing the decompressor lever.

Babetta type 28 owners handbook pages 15 to 20
The start itself is effected as under point a) (with
that difference the gas grip is rotated to ¾ of range
- the air valve should not open). The number of
kickstarts increases proportionally to the sinking
temperature of atmosphere. The method of start
under b) on the ice covered roads is not
recommended for the safety reasons.

Braking and stopping

In the case the braking is required release the gas
grip with brake levers (2,3 fig.2) and brake
down.One proceeds in the same way when
stopping the vehicle. The clutch disengages due to
the velocity decrease and the engine works on idle
run. If the drive is continued due to the releasing of
gas the clutch is engaged again and the vehicle is
put in motion. After finishing the drive the engine is
to be stopped by depressing the decompressor
lever (4, fig.2) and shut the supply of fuel by
rotating the fuel tap lever (fig.4) to the position C.
The position of lever B is the reserve and it is
sufficient for the drive of abt. 30 km.
On the moped as on the cycle
If you want to use the moped as the cycle (e.g.
when consumption
disengaging device of engine – the star-like nut in
the direction in the engine and rotate to the right
(fig.7). the nut remains fitted into this position and
the engine remains disconnected. The engine is
engaged again when you depress again the star-
like nut in the direction into the engine and rotate it
to the left.
IV. MAINTENANCE AND ADJUSTMENT

Maintenance of vehicle

When cleaning the varnished and chrome plated
vehicle parts use always the water and saponates.
After washing the varnished and chrome plated
parts wipe them with buck leather. The plastic and
rubber parts of air filter are to be washed by the
water only. The varnished and rubber parts and
plastics do not wash by kerosene, petrol or another
diluent since these parts could be deteriorated,
