DANGER● The precautions described in the instruction manuals and the precautions displayed on the products do not anticipate or assume all possible dangers. Therefore, operation, maintenance, and inspection of the products should not be limited to the matters described in the instruction manuals or displayed on the products, but should be the responsibility of the operator and should be fully considered for safety measures.● Before disassembling, release the fluid and gas charging ● Neither this warning nor notes cover all the cases. ● In order to use products safely, please strictly ● Use the products at pressure below the maximum ! WARNING● Use our special hanging tool to hang the ● When charging or discharging nitrogen gas, use protective equipment, such as gloves, safety shoes, safety glasses, and ear plugs. Keep your face away from the discharging port of nitrogen gas, and work with proper ventilation. In places where ventilation is not possible, connect a gas hose to the three-way valve, extend it outside, and release nitrogen gas from the hose.・If the nitrogen gas is discharged with your face leaning toward the discharging port, the energy from the high pressure gas, the scattered dust, or the noise could cause injury.・If the unmatched threads (specification, diameter and ・The accumulator shall be fastened properly with ● Use the same thread size.● Fasten the accumulator with clamps.IntroductionSafety PrecautionsIn order to prevent damage to the lives, health, or property of our users and those around them, please adhere to the notices shown by the symbols.The following explains the extent of injury and the damage if our products are treated improperly.serious injury.damage to the accumulator or its parts in use.pressures down to an atmospheric pressure.・If the pressure in the accumulator is not released down to an atmospheric pressure before the accumulator is disassembled, serious injuries could be caused by not only the liquid and nitrogen gas but also the scattered parts.accumulator will rise as the temperature rises.
