[1] REPLACEMENT OIL IN HYDRAULIC TANK
• Parts and oil are at high temperature immediately after the engine is stopped, and may cause
serious burns. Wait for the oil temperature to go down before performing this operation.
• When removing the oil filler cap, turn it slowly to release the internal pressure, then remove it.
• Securely close the tank cap after refilling with the oil.
• For details of using oil specified, see “Maintenance 7.1 Use of Fuel, Coolant and Lubricants
According to Ambient Temperature”.
• Be sure to put the machine in the traveling posture when checking the oil level.
Checking the oil level in the working posture will cause overfilling since the oil in the cylinders
has not returned to the tank.
For details of traveling posture, see “Operation 3.7 Machine Traveling Posture”.
• The engine must be at halt until piping and hydraulic equipment is filled with oil after
replacement of the hydraulic oil filter.
• Refill capacity: 69 liters
