4. Adjust air pressure in air springs until 102 mm (4 in.) (A) of shaft (B) is exposed on all four shafts.

5. Drive machine.

6. Verify 102 mm (4 in.) of shaft is exposed on each shaft.

7. If not, repeat steps 3, 4 and 5 until 102 mm (4 in.) distance is maintained on each shaft.

NOTE: If 102 mm (4 in.) cannot be achieved, do not inflate air springs beyond 689 kPa (6.89 bar) (100 psi).
