Open the right side cover.
Install a female quick coupler and hose on the male quick coupler (Item 1) [Figure 20-200-1].
Remove the fill cap from the reservoir. Route the hose (Item 1) [Figure 20-200-2] into the reservoir.
NOTE: Be sure the hydraulic system is filled with oil before starting the excavator to prevent damage to the system.
Start the excavator.
The excavator piston pump has a minimum displacement stop, approximately 20,4 L/min (5.4 U.S. gpm) which is being circulated through the valve even when all functions are in neutral.
If additional air has gotten into some of the circuits (motors or cylinders), the excavator can be operated with the bleed tool in place.
NOTE: When the excavator is operated with bleed hose in place, the reservoir cap is removed.
The hydraulic system must be protected from contamination and spill.
