a service agent for inspection!
STARTING ENGINE
1. Open the fuel cock (fig. 16).
2. Make sure that the sparking plug cable is prop-
erly in place.
3. Check to make sure that the power take-off is
disengaged.
4a. Senator:
Put the gear lever in neutral
4b. President-Royal-Pro16-Pro18-Pro20:
Do not keep your foot on the drive pedal.
5a. Senator-President:
Starting cold engine – put the throttle control in the
choke position. Starting warm engine – put the
throttle control at full throttle (approx. 1 cm behind
the choke position).
5b. Royal-Pro16-Pro18-Pro20:
Putthethrottlecontrolatfullthrottle.Startingcold
engine – pull the choke control out fully. Starting
warm engine – do not touch the choke control.
6. Depress the brake pedal fully.
7. Turn the starter key and start the engine.
8a. Senator-President:
Once the engine has started, move the throttle con-
trol gradually to full throttle if the choke has been
used.
8b. Royal-Pro16-Pro18-Pro20:
Once the engine has started, push the choke control
in gradually if it has been used.
9. When starting from cold, do not make the ma-
chine work under load immediately, but let the en-
gine run for some minutes first. This will allow the
oiltowarmup.
When in use, always operate the engine at full
throttle.
STOPPING
Disengage the power take-off and apply the park-
ing brake.
Allow the engine toidle 1 - 2 mins. Stop the engine
by turning off the ignition key.
Shut off the petrol cock. This is particularly impor-
tant if the machine is to be transported on a trailer
for example.
If the machine is left unattended, re-
movethelead from thesparkplug. Also
removethestarterkey.
The engine may be very warm immedi-
ately after it is shutoff. Do not touch the
silencer, cylinder or cooling flanges as it
can cause burns and injury.
CATALYTIC CONVERTER (Pro18 -
Pro20)
The catalytic converter gets very hot during opera-
tion. The heat remains for a long time after the en-
gine has been stopped. Be aware of fire risk.
Do not park in close proximity to in-
flammable objects. Do not cover the
machine until the catalytic converter
has cooled down.
STEERING AID (Pro20)
Built-in function in order to facilitate steering. The
operator only has to turn the steering wheel gently.
An hydraulic torque amplifier creates the remain-
ing force.
As opposed to a normal servo steering (e.g. in a
car), the steering aid has a limited capacity. This
means thatit has some characteristics that mightbe
considered negative:
- at a low engine rpm or in situations where extra
steering force is needed, steering can be consid-
ered to be “jumpy”.
- the machine should always be moving when the
steering is used. Avoid turning the steering
