8.2 Filling with Hydraulic Oil
• Remove the cap of the filler port cum air breather by turning it counterclockwise, then pour clean
hydraulic oil (within NAS class 10) into the tank. The volume of oil should be that sufficient to bring the
float to between the red line and yellow line.
• Use a hydraulic oil that conforms to the conditions described in “3.1.1 Product Specifications”.
CAUTION
 Running the product while the tank is not full of oil will cause seizure and/or wear of the
pump, leading to breakage.
 During the initial operation of the machine, oil is supplied to the hydraulic circuits at the
machine side and the oil in the tank may decrease. Add oil to bring the height of the oil level
to within the stipulated range.
 Depending on the hydraulic circuits at the machine side, the fluctuations in oil level in the
tank may become large, and oil may overflow from the tank or the oil level may drop. Adjust
while watching the oil level gauge to achieve the optimum oil level.
