9.4 CRANE SERVICING
9.4.1 Oil level checking
The oil level must be checked daily, with the crane in rest position and the truck on flat ground If necessary
top up with hydraulic oil. The level is checked by mean of the dipstick. (1)
9.4.2 Oil change
The oil deteriorates during daily usage. The oil change every year is necessary to avoid damages to the
hydraulic system. Take a container with a capacity of min. 2 gal and having suitable dimensions to be
positioned under the oil drain plug. (2)
ATTENTION
It is forbidden to pollute the environment with exhausted oil.
After the replacement, it is important to carry out a bleeding of the circuit, otherwise the air introduced in the
system with this operation may damage the sealing parts. To do that, operate every function of the control
box, driving it smoothly to stroke end.
Use only the oils stated in the greasing/lubricating table, or equivalent ones. (chap. 9.5)
