5.5.2Draining
1.Run the machine at variable speeds for
2.Position the machine completely horizontally.
3.Pull out both disengagement levers according to fig. 6.
4.Place one container under the rear axle and one under the front axle.
5.Open the oil reservoir by removing the cover. See 9:R.
Only a 3/8” square drive may be used for the oil plug. Other tools will damage the plug.
6.Remove the oil plug from the rear axle. Clean the hole and use a 3/8” square drive. See figure 11.
7.Remove 2 drain plugs from the front axle. Use a 12 mm socket. Allow the oil in the front axle and pipes to run out. See fig. 12.
8.Check that the gaskets on the drain plugs of the front axle are intact. See fig. 12. Reinstall the plugs. Tightening torque:
The oil plug will be damaged if it is tightened more to than 5 Nm.
9.Check that the gasket on the oil plug of the rear axle is intact. See fig. 11:Y. Reinstall in the rear axle. Tighten the oil plug to 5 Nm.
10.Draw out the oil from the deeper section of the reservoir using an oil extractor. See fig. 13.
11.Dispose of the oil according to local regula- tions.
5.5.3 Filling
The engine must never be run when the rear clutch release lever is pushed in and the front clutch release lever is pulled out.
This will damage the front axle seals.
1.Fill the oil reservoir with the new oil.
If the engine is run indoors, exhaust ex- traction equipment must be connected to the engine’s exhaust pipe.
2.Check that the rear axle’s clutch release lever is pulled out.
3.Start the engine. When the engine is started, the front axle’s clutch release lever slides inwards automatically.
4.Pull out the front axle’s clutch release lever.
NOTE! The oil is drawn into the system very quickly. The reservoir must always be topped up. Air must never be drawn in.
5.Set the accelerator pedal to the forward position by blocking it using a wooden wedge. See fig. 14. Fill the oil reservoir by hand using new oil.
6.Run in the forward position for one minute.
7.Move the wooden wedge and set the accelerator pedal to the reverse position. Continue filling with oil.
8.Run in reverse mode for one minute.
9.Change driving direction once every minute as above and continue filling with oil until the bubbling in the reservoir stops.
10.Switch off the engine, install the oil reservoir cover and close the engine cover.
11.Test drive for several minutes and adjust the oil level in the reservoir.
