1.Make sure to set the plunger's lifting time to takelonger than 0.5 second by using flow control valve withreverse check.
2.This flow control valve with reverse check should havea reverse free-flow check that has a cracking pressureof less than 0.05 MPa.This will prevent excessive backpressure that could increase the plunger's retract time.

Caution in Use
1. Surface roughness at the bottom of mounting hole should be no rougher than Rz 6.3 (ISO 4287 : 1997).
2. Tightening torque to mount should be :40 ~ 50 N.m for CSM0.2 & CSM0.3, 45 ~ 55 N.m for CSM0.4, 55 ~ 65 N.m for CSM0.6.
3. When fixing a body by vise, etc., make sure its force is less than 2.5 kN.
4. Do not block the air vent. If coolant or dust is intruding, make necessary piping.
5. Head cap should be always used in order to retain the lift spring. If fabricating head cap yourself, be sure to make an O-ring slot
and spring's spot-facing by referring to above head cap dimensions. Be sure to use the furnished O-ring at all times.
6. The furnished O-ring͆ZZ͇
should be always used.
7. If fabricating a lift spring yourself, set the dimensions by referring to the size table of head cap dimensions. Anti rust precaution
should be taken. When non-standard lift springs are used, no guarantee is provided for its action.
8. Head cap should be tightened with the designated torques as under.
30 N.m for CSM0.2 & CSM0.3
50 N.m for CSM0.4 & CSM0.6
9. Oil free air through 5ȣm filter should be used.
