ROC-2K WARNING!
- Pressure must no be applied to a ROC-2K-R 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.
S-4 WARNING!
- 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 with S-4 couplers 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.
