Dolmar RM-72.13 H Operator's Manual page 85

Mechanical transmission
Never ride the machine on slopes in
neutral gear or with the clutch out! Always engage a low
gear before leaving the machine stopped and unattended.
Hydrostatic transmission
Move on slopes with the speed change lever in the «N» position,
(to take advantage of the hydrostatic unit's braking effect) and
then further reduce the speed using the brake, if necessary.
Never use reverse for reducing speed
going downhill. Control of the machine could be lost, par-
ticularly on slippery surfaces.
5.5.5 Emptying
the grass-catcher
NOTE
This oper-
ation can only be done with the
blade disengaged, otherwise
the engine stops.
When the grass-catcher is full an
audible warning is given. STOP
FORWARD MOVEMENT, in order
not to block the collector channel,
and disengage the blade which
will stop the audible signal.
Empty the grass-catcher by lifting it using the handle.
NOTE
At times the audible warning may be heard
on engaging the blade even when the grass-catcher has been
emptied. This is due to grass cuttings left on the sensor of the mi-
cro-switch. To stop the signal, either remove the remaining grass
or disengage the blade and then immediately engage it again.
5.5.6 Emptying the collector channel
Cutting very tall or wet grass, particularly at too high a speed, can
cause the collector channel to become blocked.
Should this happen, it will be necessary to:
– stop forward movement, disengage the blade and stop the en-
gine;
– take off the grass-catcher or stone-guard;
– remove the accumulated cuttings going in through the exit of the
collector channel.
This must only be done when the engine
is stopped.
5.5.7 Card protection device
The electronic card has a self-resetting protector which breaks the
circuit if there is a fault in the electrical system. It results in the stop-
ping of the engine and is signalled by the pilot lamp turning off.
The circuit automatically resets after a few seconds but the cause of
the fault should be ascertained and dealt with to avoid re-activating
the protection device.
