Remove the cap of the oil filling port (air breather) by turning it counterclockwise, and fill clean hydraulic
oil (pollution degree: NAS Class 9 or lower level) into the tank. Set the oil level so that the float of the level
gauge is between the red and yellow lines.
Use the hydraulic oil conforming to the specifications on p. 8.
Make sure that the stop valve is opened.

CAUTION
[1] Operating the hydraulic unit with no oil in the tank causes pump seizure or wear, which may result in
pump damage.
[2] Make sure that the stop valve is opened. If the stop valve is not opened, the oil cannot be supplied into
the pump. This causes pump seizure or wear, which may result in pump damage.
[3] During initial operation of the machine, oil will be supplied into the hydraulic circuit of the machine.
Be careful about a decrease in oil level in the tank.
[4] The oil level in the tank may largely fluctuate depending on the machine hydraulic circuit. This may
result in oil leak from the tank, or decrease in oil level.
