5 - MAINTENANCE
5. The accumulator pressure should be checked annually.
6. Operational dry nitrogen pressure levels are between
700-800 psi (4826-5516 kPa) (48.3-55.2 bar). If levels
are below this range, recharge the accumulator with dry
nitrogen.
7. If pressure is 0 psi (0 kPa) (0 bar), replace the accumulator
due to an internal bladder rupture.
Always use dry inert gas (Dry Nitrogen - N2) for pre-
charging.
NEVER USE AIR OR OXYGEN, DUE TO THE DANGER
OF COMBUSTION / EXPLOSION
