Test to find any leaks
DANGER
Before checking for leakages, or going near any hydraulic fitting,
to avoid possible ejection of pressurized hydraulic oil:

Shut down the loader engine

Depressurize the hydraulic system completely

Wipe the hydraulic components clean to find leaks more
easily.

Place pieces of cardboard around the fittings to detect leaks.

Start the engine. While running on idle, operate the auxiliary
hydraulics control lever briefly a couple of times. Shut down
the engine, depressurize the hydraulics, and check for any
sign of leak. Tighten if necessary.

Repeat the test by gradually increasing engine rpm and
operating time. Use both directions of the auxiliary hydraulics
control lever.
DANGER
Risk of high pressure fluid injection through skin - Test the tightness of the
hydraulic fittings carefully.
Use idle rpm when starting the first time and keep a safe
distance due to the risk of hydraulic fluid ejection. Shut down the loader and release the
residual pressure before checking for leaks. Remember to use and wear protective
equipment.
DANGER
Risk of high pressure fluid injection through skin - Never test the tightness of the
hydraulic components by placing hands near the fittings.
Never tighten a
pressurized hydraulic fitting, since the fitting may break and the released oil may cause
serious injuries.
Check the routing of hoses and movements of the attachment
After tightening the hydraulic components, test the movements of the attachment thoroughly. Check that the
hydraulic hoses cannot get stretched or pinched in any position of the loader boom or the attachment, and
check that the hoses are not in contact with sharp edges.
After thoroughly checking visually that the hoses are connected and fittings are tightened, check the tightness
of the fittings as described above. The hydraulic system will de-air itself when using the auxiliary hydraulics of
the loader.
