Ca ution in us e

Gas Charge / Discharge● Charge Nitrogen (N 2 ) gas only. Never charge flammable, explosive gas and volatile liquid as they may cause an explosion
accident. (FIG. 1)● The charging pressure should be below the designated pressure in the marking. (FIG. 2)
Gas charging range : 3.4 MPa 〜 15 MPa (at 20℃ ).
3.4 MPa 〜 18 MPa for model DNK0350 and DNR0350 only.

● Continue to charge gas till the sound of gas flow disappear even if the pressure gauge points the set pressure. (FIG. 2)● Gas charging should be done with the piston rod fully out. If piston rod retracted in the cylinder, start charging as lower
pressure as possible ( 0.5 MPa or lower) then increase the pressure gradually till the piston rod extended out, in order to avoid
personal injury and damages of facility and equipments. (FIG. 3)● Do not charge/discharge gas while the gas spring is under load.

● Exhaust the N 2 gas completely before disposal. Refer to page → 75 for gas discharging tool.

● Those gas springs for use outside Japan (specified as -OS) are shipped without gas. The user needs to charge gas before use.
After charging gas, the charging gas pressure should be recorded on the pressure indication label of each gas spring by apermanent marker.
