X1 line circuit
X1 option is used for hammer & shear.
- Main line change:
When it is used for hammer, return line directly goes to tank. But shear uses double action. So we need 3-
way valve
- 2-step port relief valve:
2-step port relief valve always maintains high pressure except hammer use.
- X1 option pedal
- Flow control function
- Option 2-pump flow
- 2-switch control without pedal
