Installation Guidelines
Inspection: Ensure the hose insert is correctly seated in the hose and the coupling groove is undamaged.
Positioning: Place the FS40 Safety Clamp over the hose-to-coupling junction, centering it precisely over the coupling groove.
Tightening: Tighten the bolts evenly using a calibrated torque wrench to the torque values specified by EN 14420 (avoid over-tightening to prevent deformation or under-tightening which compromises safety).
Verification: Manually attempt to pull the hose axially to confirm no movement; visually inspect bolt engagement.
