3.3 Preparation for installation
a) Before starting installation work, clean and dust the working area, hands, and clothing to prevent
foreign matter from entering the product/equipment.
b) Remove the protective plug from the port and the protective plates from the port flange mounting
surface. When removing the plates, be careful not to damage the mounting surface.
Fig. 3.3a Removal of the Protective Plug and Plates
c) Check for critical scratches on the O-ring sealing surface of each port and the port flange mounting
surface. If any scratch is found, eliminate it by mending the mounting surface. If a critical
scratch that cannot be mended is found, contact our customer support.
d) Clean the O-ring sealing surface of each port and the port flange mounting surface to ensure that
there is no foreign matter, such as metal debris and lint from waste cloth.
e) Check for critical scratches on the O-ring mounting surface of the pipe flange and check that the
O-ring is properly mounted in the groove. If required, mount it in the groove correctly.
Any critical scratch on the mounting surface may cause fluid leakage, resulting in a major
accident.
Improper mounting of the O-rings may cause damage to them or outflow of hydraulic fluid,
resulting in a major accident.
