Checking oil level for brake sys-
tem and steering hydraulics
d With the engine stopped, unscrew
the knurled nut and take the lid off
the reservoir.
d Depress the brake pedal about
10 times until the oil level in the
reservoir no longer rises and
increased resistance is felt at the
pedal.
d Check oil level: it must be about
20 mm (0.8 in) below the rim of the
reservoir.

up only with Pentosin CHF 11 S or, if
not available, LHM – never use
brake fluid.
d Place the lid back on the reservoir
and tighten the knurled nut. Make
sure that the lid is correctly seated.
