500 hours service - Hydraulic filters in the tank
±
WARNING! Wear protective gloves while replacing filters to prevent the oil from making any contact with the skin.
€
DANGER! Hot oil can cause serious burns.
±
WARNING! It is essential to use an original filter.
A visual gauge (A) is located on the rear side of the hydraulic reservoir.
The filter elements (B) are located on either side of the tank. They should
always be replaced at the same time.
A drip pan should be put in place to collect the used oil contained in the
filter housing. A valve at the end of the filter housing retains the oil in the
tank.
• Completely unscrew the lid and remove the filter assembly.
• Unscrew the knob (1) to remove the filter. To facilitate this
operation, gently press the spring (2).
• Remove the caps from the filter element (3).
• Carefully clean the magnetic core (4) with a cloth.

WARNING! Before replacing the filters, note the oil level in the
tank (1).
1. Initial level before replacing filters
2. Level after replacing the filters
• After installing the new filter, the oil level will drop by about 3/8”
(10 mm), which means that the filters have been installed correctly.
• Top up with oil to the maximum level.
• Start the engine on idle then stop it after a few seconds. This
evacuates the air contained in the hydraulic system.
• Start the engine again on idle and then gradually increase the
engine speed.

Note: The oil drained from the filters must never be re-used as it may damage the hydraulic system components.
