Filling hydraulic oil
・
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. Refer to "3.2.2 Common Specifications "

CAUTION
●
Operating the hydraulic unit with no oil in the tank or closing the stop valve causes pump seizure or wear,
which may result in pump damage.
●
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.
●
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. Please adjust the oil amount to be an optimal value while
watching the oil level meter.
