Changing Engine Oil - Stiga PARK UNLIMITED Instructions For Use Manual

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.
Stop the engine.
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: 0.6 bar (9 psi).
Rear: 0.4 bar (6 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.
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. Attach the clamp on the oil drainage hose. Use
a polygrip or similar. See fig. 12:V.
2. Move the clamp up 3-4 cm on the oil drainage
hose and pull out the plug.
3. Collect the oil in a collection vessel.
NOTE! Do not spill any oil on the drive belts.
4. Hand in the oil for disposal in accordance with
local provisions.
5. Install the oil drainage plug and move the clamp
back so that it clamps above the plug.
6. Remove the dipstick and fill up with new oil.
Oil volume: 1.2 litres
7. After filling up the oil, start the engine and idle
for 30 seconds.
8. Check to see if there is any oil leakage.
ENGLISH
9. Stop the engine. Wait for 30 seconds and then
check the oil level in accordance with 4.2.
5.5 Fuel filter (11:Z)
Replace the fuel filter every season.
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 after 100 hours of
operation.
5.7.1 Checks
Briefly turn the steering wheel back and forth.
There must be no mechanical clearance in the
steering chains.
5.7.2 Adjustment
Adjust the steering chains if required as follows:
1. Put the machine in the straight-ahead position.
2. Adjust the steering chains with the two nuts, lo-
cated under the central point. See fig. 13.
3. Adjust both nuts by the same amount until there
is no clearance.
4. Test drive the machine straight forwards and
check that the steering wheel is not off centre.
5. If the steering wheel is off centre, undo one nut
and tighten the other.
Do not over-tighten the steering chains. This will
cause the steering to become heavy and will in-
crease wear on the steering chains.
5.8 Battery
If acid comes into contact with the eyes
or skin, this can cause serious injuries.
If any part of the body has come into
contact with acid, rinse immediately
with copious amounts of water and seek
medical assistance as soon as possible.
The battery is a valve-regulated battery with 12 V
nominal voltage. The battery fluid does not need to
and cannot be checked or topped up. The only
maintenance that is required is charging, for exam-
ple after extended storage.
The battery must be fully charged be-
fore being used for the first time. The
battery must always be stored fully
charged. If the battery is stored while
discharged, serious damage will occur.
5.8.1 Charging with the engine
The battery can be charged using the engine's gen-
erator as follows:
1. Install the battery in the machine as shown be-
low.
