4. Check that the rubber gasket (21:H) at the bot-
tom of the filter is intact.
5. Install the new filter and the spring in the
sleeve. Insert the filter until it snaps into place
in the sleeve.
6. Reinstall the unit in the tank. The upper section
of the filter must click securely into the recess
in the upper section of the tank.
5.6.4 Filling
1. Check that the gaskets on the 4 drainage plugs
are intact. See fig. 22. Reinstall the plugs. Tight-
ening torque: 15-17 Nm.
2. Only applies to Pro20, Pro25 and Pro Svan:
Moisten the new filter’s gasket with oil and in-
stall the filter. See fig. 16:A.
3. Fill the oil reservoir with the new oil.
4. Check that the clutch release lever (6:R) is in
the outer position (drive position).
If the engine is to be run indoors, an ex-
haust extraction device must be con-
nected to the engine’s exhaust pipe.
5. Prepare a suitable vessel with the new oil.
NOTE! The oil is sucked into the system very
quickly. The reservoir must always be kept
topped up. Under no circumstances may air
be sucked in.
6. Fill the oil reservoir with new oil.
7. Start the engine and allow it to idle. Gradually
top up the oil in the reservoir so that the level
constantly reaches the mark.
8. Reinstall the oil filler cap and close the engine
casing.
9. Reset the drive shafts’ valves in accordance
with fig. 25.
10.Drive the machine 8-10 metres forwards and 8-
10 metres backwards. If the machine has hy-
draulic power assisted steering, apply full steer-
ing lock at the same time.
11.If the machine has a hydraulic implement lifter,
raise and lower the lifter 3-4 times.
12.Adjust the oil level in the reservoir.
5.7 Belt transmissions
After 5 hours of operation, check that all the belts
are intact and undamaged.
5.8 Steering
The steering must be checked/adjusted after 5
hours of operation and thereafter after 100 hours of
operation.
5.8.1 Checks
Briefly turn the steering wheel back and forth.
There must be no mechanical clearance in the
steering chains.
5.8.2 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. 29.
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.
5.9 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.
5.9.1 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.
2. Place the machine outdoors or install an extrac-
tion device for the exhaust fumes.
3. Start the engine according to the instructions in
the user guide.
4. Allow the engine to run continuously for 45
minutes.
5. Stop the engine. The battery will now be fully
charged.
5.9.2 Charging using battery charger
When charging using a battery charger, a battery
charger with constant voltage must be used.
Contact your dealer to purchase a battery charger
with constant voltage.
The battery can be damaged if a standard type
battery charger is used.
