8. Turn battery disconnect switch ON and have an assistant start engine (TM 5-3805-298-10).
9. Have an assistant run engine at high idle (2,450 rpm) (TM 5-3805-298-10).
10. Have an assistant bring the hydraulic oil to operating temperature 140F (60C) (TM 5-3805-298-10).
11. Have an assistant raise bucket lift half way up. Tilt the bucket rearward fully. Lower bucket slowly till tilt
cylinders extend (TM 5-3805-298-10).
12. Record the pressure on the 5,800 psi (40,000 kPa) gauge (Figure 45, Item 1).
13. Tilt the bucket level to the ground and lower the bucket to the ground (TM 5-3805-298-10).
14. Turn ignition switch and battery disconnect switch to OFF position (TM 5-3805-298-10).
15. Pressure reading should be 4,000 50 psi (27,600 350 kPa).
16. Disconnect hose 177-7861 (Figure 45, Item 2) from rod end of tilt cylinder pressure port (Figure 44, Item 1).
