(2) Clean part in accordance with SECTION II – CLEANING.
根据第II节“清洁”进行清洁。
(3) Mask all areas not to be repaired.
遮盖所有不需要修复的区域。
WARNING: USE THE CORRECT PERSONAL PROTECTION. HEATED PARTS WILL CAUSE BURNS.
警告：使用正确的个人防护设备。加热部件会造成灼伤。
CAUTION: DO NOT EXCEED TEMPERATURE LIMITATIONS DURING CURE PERIOD.
注意：在固化期间，温度不得超过限制值。
(4) Before application, increase temperature of epoxy paste adhesive C01-0002 to room temperature or to 110˚F (43˚C) maximum in an oven. Discard unwanted epoxy paste adhesive that was heated for thinning purpose.
在应用前，将环氧树脂粘合剂C01-0002的温度升高至室温或烘箱中最高110˚F（43˚C）。丢弃因稀释而加热的多余环氧树脂粘合剂。
WARNING: SOLVENT VAPORS ARE TOXIC AND FLAMMABLE. DO NOT INHALE VAPORS. OBSERVE FIRE PRECAUTIONS.
警告：溶剂蒸气有毒且易燃。请勿吸入蒸气。注意防火措施。
CAUTION: MAKE SURE TO TAKE CARE IN APPLYING EPOXY PASTE ADHESIVE TO MINIMIZE THE TRAPPING OF AIR.
注意：在环氧树脂粘合剂上施加时务必小心，以尽量减少空气的滞留。
(5) Apply epoxy paste adhesive C01-0002 with sufficient thickness for finish machine. Use a spatula for epoxy paste adhesive application.
环氧树粘合剂C01-0002的涂覆厚度应足以满足精加工机器的要求。使用刮刀进行环氧树脂膏粘合剂的涂覆。
NOTE: Uncured epoxy paste adhesive C01-0002 can be cleaned from work area and application equipment using denatured alcohol.
注：未固化的环氧树脂粘合剂C01-0002可使用变性酒精从工作区域和应用设备上清洗。
WARNING: USE THE CORRECT PERSONAL PROTECTION. HEATED PARTS WILL CAUSE BURNS.
警告：使用正确的个人防护装置。加热零件会造成灼伤。
(6) Cure epoxy paste adhesive C01-0002, in an oven for one hour at 350˚F (177˚C).
在烘箱中固化环氧树脂粘合剂C01-0002，持续1小时，温度为350˚F（177˚C）。
WARNING: USE THE CORRECT PERSONAL PROTECTION. PROCEDURES THAT NEED GRIND/MACHINE WORK WILL CAUSE LOOSE PARTICLES THAT CAN GET IN YOUR EYES.
警告：使用正确的个人防护设备。需要研磨/机械加工的程序会产生松散颗粒，可能进入眼睛。
(7) Machine the part to finish dimensions. Refer to applicable Technical Manual for repaired limits.
对零件进行加工，以达到最终尺寸。有关修复限制，请参阅适用的技术手册。
(8) Examine machined part as follows:
按如下方式检查机加工零件：
(a) Examine porosities or voids of 0.015 inch (0.38 mm) minimum diameter only. Do not consider porosities of voids smaller than specified during evaluation.
仅检测孔隙或最小直径为0.015英寸（0.38 mm）的空隙（孔洞）。在评估过程中，不考虑小于规定尺寸的孔隙或空隙。
(b) Porosities or voids of 0.080 inch (2.03 mm) maximum diameter are permitted. Two porosities or voids, or all number of smaller porosities or voids with a combined area no larger than specified in a 0.50 X 0.50 inch (12.7 X 12.7 mm) area are permitted.
允许孔隙或空隙的最大直径为0.080英寸（2.03 mm）。允许两个孔隙或空隙，或者允许所有数量的较小孔隙或空隙，其总面积不超过0.50英寸（12.7mm）×0.50英寸（12.7mm）区域中规定的孔隙或空隙。
(c) No porosities, voids, or chipping down to parent metal is permitted.
不允许有孔隙、空隙或碎裂到基材。
(9) Clean the part. Refer to SECTION II – CLEANING.
清洁零件。请参阅第II节-清洁。
WARNING: SOLVENT VAPORS ARE TOXIC AND FLAMMABLE. DO NOT INHALE VAPORS. OBSERVE FIRE PRECAUTIONS.
警告：溶剂蒸气有毒且易燃。请勿吸入蒸气。注意防火措施。
CAUTION: MAKE SURE TO TAKE CARE IN APPLYING EPOXY PASTE ADHESIVE TO MINIMIZE THE TRAPPING OF AIR.
注意：在环氧树脂粘合剂上施加时务必小心，以尽量减少空气的滞留。
(10) If required, apply epoxy paste adhesive C01-0002 to porosity and/or voids with sufficient thickness for finish machine.
如需要，使用环氧树脂粘合剂C01-0002对孔隙和/或空隙进行涂覆，厚度足以满足精加工设备的要求。
WARNING: USE THE CORRECT PERSONAL PROTECTION. HEATED PARTS WILL CAUSE BURNS.
