check the spark of the sparking plug(s) (fig. 23).

The engine manufacturer recommends:
Senator-President: Champion J19LM
Royal-Pro16-Pro18-Pro20: Champion RC12YC
The correct distance between the electrodes is 0.75
mm.
COOLING AIR INTAKE - ENGINE
The engine is air-cooled. A blocked cooling sys-
tem can damage the engine. The engine should be
cleaned at least once a year or every 100 hours of
operation.
Remove the fan casing. Clean the cooling fins on
the cylinder, the fan and the rotating protective
grille (fig. 24 - 25). Clean more frequently if mow-
ing dry grass.
BATTERY
Check the acid level regularly.
The acid level should be between “UPPER and
“LOWER” on the battery. When adjusting the lev-
el, only use distilled water (battery water).
The battery acid is extremely corrosive
and can cause burns and injuries to
skin and clothing. Always use rubber
gloves and glasses (goggles) to protect
the eyes. Avoid inhaling any acid va-
pour.
Do not incline the battery too much so
that the battery acid can run out on to
hands and clothing. If this should hap-
pen, flush with lots of water.
If the battery terminals are coated with oxide, they
should be cleaned.Clean thebattery terminals with
a wire brush and grease them.
LUBRICATION - CHASSIS
The machine’s articulated steering joint has four
grease nipples that should be lubricated with uni-
versal grease after every 25 hours of operation
(fig. 26).
Please note that the fourth grease nipple is not
shown on the picture. It is located on the underside,
on the flexible axle’s front bearing.
Senator-President-Royal:
Lubricate the steering cables and steering chain
with universal grease a couple of times per season.
Pro16-Pro18-Pro20:
Apply universal grease to the steering chain a cou-
ple of times each season. If the steering chains are
really dirty, dismantle them, wash them and then
grease them once more.
Apply universal grease to all the plastic bearings a
couple of times per season.
Apply a coating of engine oil to the tension arm
joints a couple of times each season.
Apply a few drops of engine oil to both ends of the
throttle control cable a couple of times a season.
Senator:
The transmission is filled with oil (SAE 80W-90)
upon delivery from the factory. If it is not opened
(which must only be done by a specialist), normal-
ly no topping up of oil should be carried out.
STEERING CABLES (Senator -
President - Royal)
The steering cables should be adjusted for the first
time after the machine has been in operation for 2
- 3 hours, and then after every 25 hours of opera-
tion.
Put the machine in the straight-ahead position.
Tensionthesteeringcablesbytighteningupthe
nuts that are located on the underside of the articu-
lated steering joint (fig. 27). The screws in the ends
ofthecablesshouldbeheldfirmlyduringadjust-
ment so that the cables are not twisted. Use an ad-
justable wrench or similar for this purpose,
inserting it in the key handles in the ends of the
screws. Tension the cables until they are no longer
slack.
Adjust both the nuts the same amount to ensure
that the alignment of the steering wheel is not
changed.
Once the adjustment is complete, turn the steering
wheel as far as it will go in either direction. Check
that the chain does not come into contact with the
pulley, and that the cables do not become entan-
gled with the steering pinions.
Do not tension the steering cables too hard. Other-
wise the steering will be heavy and wear and tear
on the cables will increase.
