5.6 TRANSMISSION, OIL FILTER
The oil and the filter in the hydraulic power trans-
mission must be checked/adjusted or replaced at
intervals according to the table below.
Action
Check – adjusting level.
Changing oil.
Changing tank filter.
Oil type: Synthetic oil 5W-50.
Oil volume at change: approx. 4.2 litres.
5.6.1 Check – adjustment
1. Place the machine on a flat surface.
2. Read off the oil level in the reservoir. See fig.
20. The level should be level with the line.
3. If necessary, top up with more oil.
5.6.2 Draining
1. Operate the machine at varying speeds for 10-
20 minutes in order to warm up the transmission
oil.
2. Open the drive shafts' valves in accordance
with fig. 21.
3. Place one collection trough under the rear axle
and one under the front axle.
4. Remove 2 drainage plugs from each axle. Use a
12 mm socket wrench. See fig. 22.
5. Remove the filler cap from the oil tank.
6. Allow all the oil to run out into the collection
trough.
7. Draw out the oil from the deeper section of the
reservoir using an oil extractor. See fig. 23.
8. Hand in the oil for disposal in accordance with
local provisions.
5.6.3 Replacing the oil filter in the tank
1. Depress the filter sleeve (24:F) in the upper sec-
tion of the tank and move the sleeve forward to
the hole.
2. Grasp the filter sleeve and spring.
3. Pull the filter (24:G) from the sleeve.
4. Check that the rubber gasket (24: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. Fill the oil reservoir with the new oil.

3. 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.
4. 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.
5. Fill the oil reservoir with new oil.
6. Start the engine and allow it to idle. Gradually
top up the oil in the reservoir so that the level
constantly reaches the mark.
7. Reinstall the oil filler cap and close the engine
casing.
8. Reset the drive shafts' valves in accordance
with fig. 25.
9. 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.
10.If the machine has a hydraulic implement lifter,
raise and lower the lifter 3-4 times.
11.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. 26.
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.
