DESCRIPTION(Figure 1) Main components of Hydraulic Crimping Head 1490746- -1 include a “C”- -head, which houses the stationary die, the upper and lower die release buttons which release the dies, a cylinder which contains the head’s hydraulic chamber, a piston (ram) which holds and controls the moving die, and a quick- -disconnect coupling (cylinder half) which mates with the coupling on the hose to release or supply pressure. A dust cap covers the quick- -disconnect coupling. 3. INSTALLATION 3.1. Head Installation Prior to installing thehead, ensure that the pump and hose being used are working properly, and are adjusted to and rated at 10,000 psi. An incorrectly adjusted or rated pump/hose could result in severe tooling damage, as well as personal injury. 1. Release the hydraulic pressure to the hose. Disconnect electric power unit from power supply. 2. Remove protective dust caps. 3. Thoroughly clean the coupling on the pump/hose and the coupling on the crimping head. 4. Mate both quick- -disconnect couplings and tighten the collar of the coupler assembly on the hose. Oil flow must be unobstructed between the power unit and the crimping head. Ensure that all couplings are fully mated and tightened. If a crimping head must be removed after the power unit was in operation, be sure to release the pressure in the hydraulic system. When using Hydraulic Power Unit 1583660- -[ ], DISCONNECT THE POWER UNIT FROM THE POWER SUPPLY. When using Hydraulic Foot Pump 1583659- -1 or Hydraulic Hand Tool 1583661- -1, depress the pressure release pedal to release pressure. ORIGINAL INSTRUCTIONS NOTE i CAUTION CAUTION NOTE i
