ALS-ELECTRONICS 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. 9-4
