3 / 4 page 408- 4321 Pneumatic CERTI- CRIMP Tool Holder 356304- 1 3 of 4 Rev C Tyco Electronics Corporation 4. Slowly crimp the contact onto the wire until the crimping dies bottom on the shim. Check that the ratchet releases after the dies bottom. Before adjusting the ratchet pawl position, DISCONNECT THE TOOL FROM THE AIR SUPPLY. After the adjustment, ALWAYS ensure that the tool holder pivot pins are fully tightened to avoid personal injury or damage to the tool. 5. If the ratchet releases before the dies bottom, loosen the three securing screws, remove the eccentric adjustment screw (refer to Figure 1) and rotate the eccentric clockwise to a higher setting. Tighten the securing screws. Repeat as required. If the ratchet does not release and the tool will not return, slowly actuate the tool until the force of the cam teeth is off the pawl, then push on the pawl with a small screwdriver until the pawl is released from the teeth, release the tool switch and allow the tool to return. See Figure 3. Figure 3 Ratchet Pawl with Emergency Release Press Pawl with Screwdriver 6. If the ratchet does not release after the crimping dies bottom, loosen the three securing screws, remove the eccentric adjustment screw and rotate the eccentric counterclockwise to a lower setting. Tighten the securing screws. Repeat as required. 7. If the crimp cannot be made to conform to the dimensions provided in the appropriate application specification, the crimp head adapter and/or crimping dies are defective and must be replaced. 5. MAINTENANCE AND INSPECTION To avoid injury, DISCONNECT TOOL FROM AIR SUPPLY before performing any maintenance or inspection procedures. Tyco Electronics recommends that a maintenance and inspection program be performed periodically to ensure dependable and uniform terminations. The tool holder should be inspected once a week. Frequency of inspection should be adjusted to suit your requirements through experience, and depends on: S Care, amount of use, and handling of tool holder S Type and size of the products crimped S Degree of operator skill S Presence of abnormal amounts of dust and dirt S Your own established standards. The tool holder is thoroughly inspected before packaging. Since there is the possibility of damage during shipment, the tool holder should be inspected immediately upon arrival at your facility. 5.1. Maintenance A. Cleaning Remove dust, moisture, and other contaminants with a clean, soft brush, or a soft, lint--free cloth. Do NOT use objects that could damage the tool. Lubricate tool holder as instructed in Paragraph 5.1,B, Lubrication, before placing the it back into service. B. Lubrication Lubricate all pins, pivot points, and bearing surfaces with a high quality grease. Tyco Electronics recommends the use of MolykoteH grease, which is a commercially available lubricant. Lubricate according to the following schedule: Holder used in daily production—lubricate daily Holder used daily (occasional)—lubricate weekly Holder used weekly—lubricate monthly Wipe excess grease from tool holder, particularly from die closure areas. Grease transferred from the die closure area onto certain terminations may affect the electrical characteristics of an application. 5.2. Periodic Inspection Regular inspections of the tool holder should be performed by quality control personnel. A record of scheduled inspections should remain with the tool holder or be supplied to supervisory personnel responsible for the tool holder. Inspection frequency should be based upon amount of use, working conditions, operator training and skill, and established company standards. 1. Inspect the tool holder for missing pins or parts. If parts are missing or defective, replace them by referring to Figure 4. 2. Check all bearing surfaces for wear. Replace any worn parts. 3. Inspect crimping dies for flattened, chipped, or broken areas. Worn or damaged surfaces are objectionable and will affect the quality of the crimp.
