HANDLING OF THE PRESSURE ACCUMULATOR
• Danger of injury! Pressure accumulator is filled with high-
ly pressurised nitrogen.
Do not open or damage the pressure accumulator.
• Immediately inform your Komatsu dealer, if you detect mal-
functions or defects of pressure accumulators.
• Filling the pressure accumulator with gas or topping up gas
in the pressure accumulator is strictly limited to persons au-
thorised to handle highly pressurised gas.
• Do not hit against the pressure accumulator.
• Keep naked light and sources of heat away from pressure
accumulator.
• Do not drill holes into the pressure accumulator.
• Do not weld parts to the pressure accumulator.
• The service technicians must depressurise the hydraulic
system before they can remove the pressure accumulator.
• The service technician must let the gas escape before they
can disassemble the pressure accumulator.
• Have the gas pressure of the pressure accumulators
checked either every 1,000 operating hours or once every
year.

• In countries with a hot climate, the responsible Komatsu
dealer must check the gas-pressure of the pressure reser-
voir already every 650 hours.
