cylinders.
4. The machine should now be in the
“Field Lowered Po-
sition”
WARNING
Only qualified and trained personnel should perform this
procedure. Always wear personal protective equipment.
WARNING
HIGH PRESSURE VESSEL
Avoid injury from high pressure escaping
hydraulic fluid.
• Relieve pressure from hydraulic system before
servicing
• Precharge with dry nitrogen gas only.
Failure to comply could result in serious injury or
death.
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.
WARNING
Always use dry inert gas (Dry Nitrogen - N2) for pre-
charging.
NEVER USE AIR OR OXYGEN, DUE TO THE DANGER
OF COMBUSTION / EXPLOSION
