Engine oil
Checking oil level
e Attention:
The red warning light
p (b7)
for engine oil pressure indicates
that the oil pump is delivering
very little oil or none at all: do
not regard this light as an oil
level indicator. Oil pressure
builds up after 1 – 2 seconds
and the warning light goes out –
the red engine oil pressure
warning light
p should remain
off when the engine is running.
Check the oil level regularly,
each time you stop for fuel (or
every second time at the latest).
e Attention:
The dipstick might show a low
oil level if the motorcycle has
been out of use for a lengthy
period. Under these circum-
stances top up the oil level only
after measuring the oil level in
accordance with the instruc-
tions.
Check the oil level only when
the engine is at operating tem-
perature.
Checking the oil level when the
engine is cold, just after the en-
gine has been run briefly or
when it is not properly warm will
falsify the reading, and could
lead to the engine being operat-
ed with the wrong quantity of oil
in the system.

Refuelling
d Warning:
Fuel is flammable and explo-
sive. Do not smoke. Never
bring a naked flame near the
fuel tank.
Fuel expands when hot (for
instance if the fuel tank is in
the sun). Consequently, add
fuel only until the pump noz-
zle automatically cuts off the
supply.
e Attention:
Leaded fuel will destroy the cat-
alytic converter.
Do not run the fuel tank dry or
you may damage the engine or
catalytic converter.
Wipe off plastic parts immedi-
ately if they are wetted with fuel.

the brake circuit:
– Do not turn the handlebars in the clamping blocks

sure at the handbrake lever
and the brake pedal before
starting each journey.

Do not ride the motorcycle if
you have any doubts about
the safety of the brake sys-

Checking brake fluid levelGradual wear of the brake pads
causes the brake fluid level in
the reservoir to drop.

the brake system checked
without delay by a specialist

must be changed regularly
by a specialist workshop,
