A. General
通用
WARNING: CLEANING PROCEDURES SHALL BE ACCOMPLISHED IN A WELL-LIGHTED, WELL-VENTILATED AREA WITH ADEQUATE SAFETY AND FIRE PREVENTION EQUIPMENT READILY AVAILABLE.
警告：清洁程序应在光线充足、通风良好且配备充足的安全和消防设备的区域进行。
(1) Compounds or materials, along with manufacturer’s addresses, are listed in SECTION VII, under Consumables.
化合物或材料以及制造商地址列于SECTION VII的消耗品项下。
(2) Prior to cleaning record all identifying marks that could be removed by the cleaning and repainting process. Parts shall be remarked using same method and location. (Refer to Repair Method No. 414A – Marking of parts.)
在清洁前，应记录所有可能因清洁和重新喷漆而消失的识别标记。零件应使用相同的方法和位置进行标记。（请参阅维修方法No. 414A——零件标记。
(3) Cleaning procedures for individual parts shall be consistent with good shop practices and the following procedures:
单个零件的清洁程序应符合良好的车间操作规范，并遵循以下程序：
NOTE: Correct and thorough cleaning for all parts is important to the successful inspection, overhaul, and satisfactory operation after overhaul.
注：对所有零件进行正确彻底的清洁对于成功检查、大修和大修后满意操作非常重要。
WARNING: USE CORRECT PERSONAL PROTECTION. SOLUTIONS USED FOR CLEANING ARE HAZARDOUS. AVOID INHALING FUMES, DUST, OR MIST. AVOID CONTACT WITH SKIN. AFTER PREPARATION, WASH HANDS AND FACE THOROUGHLY. SOLVENT VAPORS ARE TOXIC AND FLAMMABLE. DO NOT INHALE VAPORS. OBSERVE FIRE PRECAUTIONS. METHYL-ETHYL-KETONE (MEK) IS TOXIC AND FLAMMABLE. USE IN WELL-VENTILATED AREA. AVOID BREATHING FUMES OR CONTACT WITH SKIN. OBSERVE ALL FIRE PRECAUTIONS.
警告：请正确使用个人防护装备。清洁所用的溶液具有危险性。避免吸入烟雾、灰尘或雾气。避免与皮肤接触。准备工作后，请彻底清洗双手和面部。溶剂蒸汽有毒且易燃。请勿吸入蒸汽。遵守防火预防措施。甲基乙基酮（MEK）有毒且易燃。请在通风良好的区域使用。避免吸入烟雾或接触皮肤。遵守所有防火措施。
(a) All metallic parts shall be cleaned to remove oil, grease, rust stains, and soiled areas. Flange areas, register diameters, and sealing surfaces shall be cleaned of oil, gaskets, and sealing compounds, if present. Remove adherent gasket or sealing compound residues using acetone (ASTM D 329) (SECTION VII) or methl-ethylketone (MEK) (ASTM D470) (SECTION VII) and a soft or stiff fiber bristled brush.
所有金属零件应进行清洁，去除油污、油脂、锈迹和脏污区域。法兰区域、限流孔直径和密封表面应清除油污、密封垫和密封化合物（如有）。使用丙酮（ASTM D 329）（SECTION VII）或甲基乙基酮（MEK）（ASTM D470）（SECTION VII）和软或硬纤维刷清除残留的密封垫或密封化合物。
(b) Clean painted parts, but do not remove paint if paint is still serviceable.
