Lower the bucket to the ground, stop the engine, actuate the parking brake and block the wheels. Turn the ECSS pressure releasing switch to the “Release pressure” position only when disconnecting the ECSS piping or removing related equipment. Otherwise keep this switch in its NORMAL position or the boom will raise unexpectedly. 1. Loosen the oil filler port cap to release pressure from the hydraulic oil tank. 2. Turn the starter switch to the ON position. Do not start the engine. 3.
Turn the ECSS accumulator pressure releasing switch to the “Release pressure” position. Set the boom lift lever to the raise position. Bucket should rise instantaneously when the pressure is released properly. 4. Operate the control levers two or three times to release trapped pressure from inside the circuits. 5. Repeat steps 2, 3 and 4 as necessary until the bucket does not move. When there no longer is enough pressure in the circuit to move the bucket, the starter switch can be turned OFF and piping work begun. WA450-3MC 5-10
