The oil reservoir for the tilt cab, track tension and optional tower winch circuits is located on the right
side of the engine. It is required to remove the aluminium side panel to access the reservoir. The oil
level should be checked when the oil is warm. Proceed as follows.
1.
Park the vehicle on level ground and turn off the engine;
2.
Lower the front blade and the tiller.
3.
Remove the aluminum right side panel to access the reservoir;
4.
Using the appropriate tool, unscrew (item1) the breather completely;
5.
Use a clean metal rod or wood stick to evaluate the oil level in the reservoir. The level should
be at the maximum in the reservoir.
If the tracks are under tension, the oil level should be around 3/4 full. The last 1/4 of the tank is
used for the track tensioning function.

If necessary, fill up with specified hydraulic fluid. Reinstall the breather.
