Even if there are no abnormalities in appearance, there may be scratches, pinholes, etc. inside the hose. Replace the hose regularly taking the operating conditions into account.Note 1. The operating temperature range shown above can be applied to the hose alone. Note 2. The approx. weight represents the weight of the hose alone. It does not include the joints at both ends and the protection.Couplers (HS Series) ● The HS-1 models are a self-sealing type that prevents oil leakage. ● A duster cap (made of resin) is attached to all models. ● Do not apply pressure to the H type or R type coupler alone. Otherwise, the equipment may be damaged.● It is dangerous to connect or disconnect the couplers while pressure is applied. Doing so may allow compressed oil to flow out, causing injury.● Securely and completely connect the couplers. Not doing so could cause pressure not to rise, the hydraulic oil not to flow, or other problems. ● If the pressure fluctuates often or vibration is transmitted to the couplers, regularly check the looseness of the cap nut. ● If a cylinder that works normally stops suddenly, the most likely cause is looseness (a gap) between the couplers. Tighten the couplers again using a tool if a gap exists. ● A duster cap is included with a coupler. Attach the cap to the coupler after use to prevent dust.203Joints (FMSH Series) ■FMSH-M22 x 3/8UH03-1NCHS-1RFMSH-M22x3/8
