MAINTENANCE
Start the engine. Check to make sure there is space to
extend the telescopic boom completely. Raise and
lower the boom a number of times. Extend and retract
the boom a number of times.
With the boom in the transport position, drive the
vehicle carefully forwards. Steer the vehicle to the
right and left.
Park the vehicle and check the oil level. Add oil if
necessary.
Hydraulic fluid filter
The vehicles use a single filter for hydraulic fluid: the
filter placed on the inside of the hydraulic tank has the
combined function for oil at the suction as well as
return.
Stabilise the vehicle to facilitate accessibility to the
filter in question: clean the filter housing and
surrounding areas to prevent dirt from entering the
circuit. Unscrew the cap.
Replacement of the filter cartridge does not necessary
involve drainage of the tank: the filter housing has a
special closure system. When it is being removed, the
oil present inside the filter normally flows out.
Remove the filter cartridge and dispose of according
to the regulatory standards in force. Insert a new filter
cartridge of the same type.
Refit the filter cover. Start up the engine and check for
leaks.
Check for a drop in the oil level through the window
present on the tank: if required, top up with the quantity
necessary to reach the correct level.
