WARNING
Dry nitrogen is the only gas approved for use in pilot oil accumulator. Any other gas may
cause failure of pilot oil accumulator or injury to personnel.
NOTE
Pilot oil accumulator charge pressure should be 120-130 psi (827-896 kPa).
7. Ensure valve handle on nitrogen chuck (Figure 5, Item 6) is closed.
8. Attach nitrogen chuck (Figure 5, Item 6) to valve (Figure 5, Item 3).
9. Ensure that needle valve (Figure 5 Item 5) is closed.
10. Open valve handle on nitrogen chuck (Figure 5, Item 6).
11. Check pilot oil accumulator pressure on pressure gauge (Figure 5, Item 1). Pilot oil accumulator charge pres-
sure should be 120-130 psi (827-896 kPa).
12. If pilot oil accumulator pressure is not within acceptable range, replace pilot oil accumulator (Figure 5, Item 2).
13. Remove nitrogen chuck (Figure 5, Item 6) from valve (Figure 5, Item 3).
14. Install protective cap (Figure 5, Item 4) on valve (Figure 5, Item 3).
15. Install right engine access panel (WP 0348).
