Tool Assembly and Inspection
WARNING
To prevent serious injury, proper assembly and
inspection of the Hydraulic Knockout Sets is
required. Inspection procedures should be per-
formed before each use
Assembly
1. Clean all the areas around the oil port of the pump
and ram. Inspect all threads for signs of wear or
damage and replace as needed. Clean all hose
ends, couplers and union ends. Remove the thread
protector (if so equipped) from the hydraulic oil outlet.
2. Connect the hose half coupler at the end of the hose
to the ram half coupler on the cylinder. Turn the col-
lar completely on hand-tight
(Figure 1).
