4085-001 6. Preventive Maintenance This chapter contains lubrication specifications. Follow these recommendations to prevent problems and maintain optimum performance. Lubrication Specifications Lubricate only when parts are replaced or as needed, not on a scheduled basis. Use of lubricants other than those specified can cause premature failure. Some unauthorized lubricants may chemically attack polycarbonate parts. Use IBM no. 10 oil, PN 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100, Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent Shell Darina 1), and grease, PN 99A0394 Nyogel 744 to lubricate appropriate areas of the machine. Numbers in {} refer to items in Assembly 4: Carrier Transport. Carrier Shafts • Apply Nye Nyogel 744 uniformly across the top portion of the 8mm {1} and 12mm carrier shafts. The grease should be visible to the eye on the shafts, but not dripping from the shafts. Use 0.03 to 0.06 grams for the 8mm shaft {1}. For reference, use 0.08 to 0.16 grams for the 12 mm shaft. • Remove any excessive coatings or accumulations with a lint- free cloth. When applying Nyogel 744 to the top of the 8mm shaft, ensure that no grease contacts the encoder strip as a carrier system stall could result during the Power-OnSequence or during printing. Note: Do not let the Nyogel 744 come in contact with the pogo pin housing. May cause machine failure. Carrier Transport System Pulleys • Apply Shell Tellus #100 to the pulley bores of the top idler pulleys {3} and tensioner {13}. The amount of oil to b used should be visible in the pulley bore, but should not drip. For reference, use approximately 0.003 grams per pulley. Preventive Maintenance 6-1
