| Hydraulic system reset procedure (Releasing Tank Pressure) | 1. Position the machine on level ground with the bucket and dipper rams fully extended and the boom lowered to rest the attachment on the ground. 2. Stop the engine. 3. Remove the starter key. 4. Use the small Allen key supplied in the tool kit to loosen the spring-loaded retaining pin at the side of filler cap C. 5. Rotate the bolt 1/4 turn anti-clockwise against the spring and hold there. 6. Carefully unscrew the filler cap C approximately 10° until the pressure starts to release. 7. Remove the Allen key. 8. Leave the filler cap C at this setting to allow the pressure to release fully. 9. Verify by carefully removing the filler cap. | p. 35 |
