Change the hydraulic fluid filter
Always wear protective goggles when working
with compressed air.
Carefully clean around the hydraulic filter.
Remove the filter (1) and take to an environmentally-
compliant waste disposal station. The filter is of the
disposable type and cannot be cleaned.
Make sure that the old seal is not left on the filter head.
Otherwise, there will be a leak between new and used seals.
Thoroughly clean the sealing surface of the filter holder.
Apply a thin coat of fresh hydraulic fluid on the new filter seal.
Tighten the filter until its seal is in contact with the filter
holder. Right after that, turn an additional half revolution.
Do not tighten the filter too hard as this could damage the
seal.
Start the engine and check that there is no leakage of hydraulic
fluid from the filter. Check level of fluid in the sight glass and top
up as required test.

Wipe clean, unscrew the plugs (1, 2 and 3) and drain the oil into
a suitable receptacle with a capacity of about 5.0 litres (5.3 qts).
Refit the drainage plug (1) and top up with oil up to the level
plug (3).
Ensure that the oil level reaches up to the lower edge of the
plug opening.
Replenish the oil to the right level if the level is low. Use
transmission oil (see lubricant specifications).
Clean and refit the plugs.
