5 MAINTENANCE
5.1 SERVICE PROGRAMME
In order to keep the machine in good condition as
regards reliability and operational safety as well as
from an environmental perspective, STIGA's Ser-
vice programme should be followed.
The contents of this programme can be found in
the attached service log.
Basic service must always be carried out by an au-
thorised workshop.
First service and intermediate service should be
carried out by an authorised workshop, but can
also be carried out by the user. The content of this
can be found in the service log and the actions are
described under "4 STARTING AND OPERA-
TION" as well as below.
Servicing carried out at an authorised workshop
guarantees professional work using genuine spare
parts.
At each basic service and intermediate service car-
ried out at an authorised workshop, the service log
is stamped. A service log presenting these services
is a valuable document that improves the ma-
chine's second-hand value.
5.2 PREPARATION
All service and all maintenance must be carried out
on a stationary machine with the engine switched
off.
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by disconnecting the spark plug
cable(s) from the spark plug(s) and re-
moving the ignition key.
5.3 TYRE PRESSURE
Adjust the air pressure in the tyres as follows:
Front: 0.4 bar (6 psi).
Rear: 1.2 bar (17 psi).
5.4 CHANGING ENGINE OIL
Change engine oil for the first time after 5 hours of
operation, 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.
Use oil according to the table below.
Oil
SAE 10W-30
Service class
SJ or higher
Use oil without any additives.
ENGLISH
Do not fill with too much oil. This can cause the
engine to overheat.
Change oil when the engine is warm.
The engine oil may be very hot if it is
drained off directly after the engine is
shut off. Therefore allow the engine to
cool a few minutes before draining the
oil.
1. Unscrew the oil drain plug (fig. 9).
2. Collect the oil in a collection vessel. Then take
the oil to a recycling station. Do not spill any oil
on the drive belts.
3. Screw in the oil drain plug.
4. Remove the dipstick and fill up with new oil.
Oil quantity: 1.2 l
5. After filling up the oil, start the engine and idle
for 30 seconds.
6. Check to see if there is any oil leakage.
7. Stop the engine. Wait for 30 seconds and then
check the oil level in accordance with 4.2.
5.5 FUEL FILTER (7:Q)
Replace the fuel filter every season. Check for fuel
leaks once the new filter has been installed.
5.6 BELT TRANSMISSIONS
After 5 hours of operation, check that all the belts
are intact and undamaged.
5.7 STEERING
The steering must be checked/adjusted after 5
hours of operation and thereafter every 25 hours of
operation.
5.7.1 Checks
Briefly turn the steering wheel back and forth.
There must be no mechanical clearance in the
steering.
5.7.2 Adjustment
Tension the steering cables by tightening up the
nut (fig. 10). Important! The screws in the ends of
the cable should be held firmly during adjustment
so that the cable is not twisted. Using an adjustable
wrench or similar, grasp the key handle on the
screws in the ends of the cable.
Adjust the steering cables until all play is removed.
Do not tension the steering cables too hard. Other-
wise the steering will be heavy and wear and tear
on the cables will increase.
