SERVICE AND MAINTENANCE
SERVICE PROGRAM
In order to keep the machine in good condition, as
regards reliability and operational safety as well as
from an environmental perspective, STIGA’s serv-
ice program should be followed.
The contents of this program can be found in the
attached service log.
We recommend that an authorised workshop car-
ries out every service. This guarantees that the
work is performed by trained personnel and with
genuine spare parts.
At every service, the service log should be
stamped. A “fully stamped” service log is a valua-
ble document that improves the machine’s second-
hand value.
PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by always stopping the engine,
disconnecting the spark plug cable
from the spark plug and earthing it.
Disconnect the negative cable from the
battery.
CLEANING
To reduce the risk of fire, keep the en-
gine, silencer/catalytic converter, bat-
tery and fuel tank free from grass,
leaves and oil.
To reduce the risk of fire, regularly
check the machine for oil and/or fuel
leakage.
When washing the machine with water under high
pressure, do not point the jet directly at the trans-
mission.
Do not point jets of water directly at the engine.Use a brush or compressed air in order to clean it.
ENGINE OIL
(Master - Senator - President)
Change engine oil the first time after 5 hours of op-
eration, and subsequently after every 50 hours of
operation or once a season.
Change the oil more often (after 25 hours of oper-
ation or at least once a season) if the engine has to
operate under demanding conditions or if the am-
bient temperature is high.
Change oil when the engine is warm. Always use
a good grade of oil (service grade SF, SG or SH).
Theengineoilmaybeveryhotifitis
drained off directly after the engine is
shut off. So allow the engine to cool a
few minutes before draining the oil.
Unscrew the oil drain plug (fig. 9). It is situated on
the left of the engine (machine viewed from the
rear).
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
Screw in the oil drain plug.
Remove the dipstick and fill up with new oil to the
“FULL” mark.
Oil capacity: 1.4 litres
Oil type, summer (> 4ºC): SAE-30
(SAE 10W-30 can also be used. However, oil con-
sumption may increase somewhat if 10W-30 is
used. Therefore, check the oil level more regularly
if you use this type of oil).
Oil type, winter (< 4ºC): SAE 5W-30
(if this oil is not available, use SAE 10W-30).
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
ENGINE OIL (Royal)
Change the oil for the first time after 20 hours of
operation (or during the first month), and then after
every 100 hours of operation or once every 6
months.
Change oil when the engine is warm. Always use
a good grade of oil (service grade SF, SG or SH).

Unscrew the oil drain plug at the end of the pipe
(fig. 10).
Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not allow oil to
get on the V-belts.
Screw in the oil drain plug. Make sure that the fibre
gasket and the O-ring inside the plug are not dam-
aged and that they are in the correct place.
Remove the dipstick and fill up with new oil up to
the “UPPER” mark.
Oil quantity: 0.9 l(= oil quantity at change. In to-
tal the engine holds 1.15 l).
Oil type for all seasons: SAE 10W-40.
For extremely low temperatures (< -20° C), use
SAE 5W-30.
Use oil without any additives.
Do not fill with too much oil. This can cause the
engine to overheat.
AIRFILTER-ENGINE
Master-Senator-President:
Clean the pre-filter once a year or after every 25
hours of operation, whichever comes first.
Clean the paper filter insert once a year or after
every 100 hours of operation, whichever comes
first.
Royal
Clean the air filter (pre-filter and paper filter) eve-
ry 3 months or after every 50 hours of operation,
whichever comes first. Change paper filter insert
once a year or every 200 hours of operation.
All models:
Note! Both filters should be cleaned more often if
the machine operates on dusty ground.
1. Remove the protective cover of the air filter (fig.
11 - 12).
2. Dismantle the paper filter insert and the foam
pre-filter. Make sure that no dirt gets into the car-
burettor. Clean the air filter housing.
3. Wash the pre-filter in liquid detergent and water.
Squeeze dry. Pour a little oil on the filter and
squeeze in the oil.4. Clean the paper filter insert as follows: Knock it
lightly against a flat surface. If the filter is very
dirty, change it.
5. Assemble in the reverse order.
Petroleum-based solvents such as kerosene may
not be used for cleaning the paper filter insert.
These solvents can destroy the filter.
Do not use compressed air for cleaning the paper
filter insert. The paper filter insert must not be
oiled.
SPARK PLUG
Clean the spark plug after every 100 hours of oper-
ation or once a season. For replacing a spark plug,
a spark plug sleeve A and a torsion pin B are pro-
vided in the accessories bag.
The engine manufacturer recommends:
Master - Senator - President: Champion J19LM.
Royal: NGK BPR5ES or DENSO W16EPR-U.
Correct spark gap: 0.75 mm (fig. 13).
COOLING AIR INTAKE - ENGINE
(Master - Senator - President)
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. 14). Clean more frequently if mowing
dry grass.
BATTERY
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery is completely main-
tenance free. You don’t have to check or top up the
electrolyte level (fig. 15).
On delivery, the battery is in the accessories box.
The battery must be fully charged be-
fore being used for the first time. The
battery should always be stored fully
charged. If the battery is stored while
totallyflatitcouldsustainpermanent
damage.
If the machine is not going to be used for an ex-
tended period (more than 1 month), the battery
should be charged, disconnected and then stored in 
						

							13
ENGLISHGB
a cool, safe place. Charge the battery completely
before reinstalling.
The battery can be charged in two ways:
1. Via a battery charger (recommended). This must
be a charger with constant voltage. The battery
can be damaged if a standard type battery
charger (for acid batteries) is used.
Stiga recommends a battery charger with item
no. 1136-0602-01 which may be ordered from
an authorised dealer.
2. You can also allow the engine to charge the bat-
tery. In this case it is very important, above all
when starting the machine for the first time and
when it has not been used for a long time, to al-
low the engine to run continuously for at least
45 minutes.
Do not short circuit the battery’s termi-
nals. Sparks occur which can result in
fire. Do not wear metal jewellery which
can come into contact with the battery
terminals.
In the event of damage to the battery
casing, cover, terminals or interference
to the strip covering the valves, the bat-
tery should be replaced.
If the battery terminals are coated with oxide, they
should be cleaned. Clean the battery terminals with
a wire brush and grease them.
LUBRICATION - CHASSIS
The machine has three grease nipples on the rear
axle which are lubricated with universal grease
every 25 hours of operation
(fig. 16).
President-Royal:
Lubricate the steering cables and steering chain
with universal grease a couple of times per season.
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 cables a couple of times a season.
Master - Senator:
The transmission is filled with oil (SAE 80W-90)
on delivery from the factory. If it is not opened
(which must only be done by a specialist), no top-
ping up of oil should normally be carried out.President - Royal:
The hydrostatic transmission is filled with oil
(10W-30) on delivery from the factory. Unless it is
opened (only to be done by a specialist), and pro-
vided no leakage occurs, no topping up with oil
should normally be carried out. Transmission oil
does not normally need to be changed.
STEERING CABLE
The steering cable 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.
Tension the steering cable by tightening up the nut
(fig. 17). Important! The screws in the ends of the
cable should be held firmly during adjustment so
that the cable is not twisted. Use an adjustable
wrench or similar, inserting it in the key handle in
the ends of the screws.
Adjust the tension until all play is removed.
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.
