6.1 SAFETY RECOMMENDATIONS

WARNING! You must go to a special-
ized Service Centre or contact your Dealer if
the following are malfunctioning:
– the brake;
– the cutting means engage and disengage
functions,

6.2 ACCESSING THE ENGINE (Fig. 6.1)
Turning over the engine cover (1), you can ac-
cess the engine and all the mechanical parts
below it.
To perform this operation, you need to:
– position the machine on a flat surface, move
the cutting-means assembly to the fully raised
position and place some shims (2) measuring
about 65-70 mm under the edge to support
it while you proceed with the required opera-
tions;
. move the transmission release lever to the
«ENGAGED» position (see 4.23), as the park-
ing brake must be disengaged to allow the
speed change lever to be moved;
– remove the grass catcher;
– unscrew the lever knob (3) and shift the lever
to the «R» position;
– open the access hatch (4) and unscrew the
fastener nut (5) using a 13 mm key;
