Checking the Nitrogen
Charge
Service Interval: Every 100 hours
WARNING
Within the breaker is a chamber containing
pressurized nitrogen, which under the right
circumstances could explode, injuring or
killing you or bystanders.
• Do not take apart the body of the breaker.
• Do not attempt to charge the chamber
yourself. Always take the breaker to an
Authorized Service Dealer for charging.
• Ensure that the breaker is charged only
with nitrogen. Other gases can explode.
• Do not ship the charged breaker via air
freight.
Inside the breaker is an accumulator, a chamber of
pressurized nitrogen. After several hours of use the
pressure may decrease, reducing the performance
of the breaker.
Strong vibrations in the auxiliary hydraulic hoses are a
sign the pressure is dropping in the chamber. If this
should happen, bring the breaker to your Authorized
Service Dealer to be charged.
Nitrogen gas pressure: 8 bar (116 psi)

Checking the Hydraulic
Lines
Service Interval: Before each use or daily
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed
within a few hours by a doctor familiar with
this form of injury; otherwise, gangrene may
result.
• Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks; never use your hands.
