喷枪的油泵清洗：在长时间不工作或者需要更换油漆时，关掉喷枪气压，拿起吸料盘，把喷枪及油泵里面的油漆打回油桶。打干净后放入洗枪水里面循环清洗，如上。（如果油漆含固化剂或PU油，则洗枪水不能循环使用，用一次即可。避免洗枪水和油漆产生固化剂凝固在油管及油泵里面）。
Oil pump cleaning of the spray gun: when it is not working for a long time or needs to change the paint, turn off the air pressure of the spray gun, pick up the suction tray, and return the paint in the spray gun and the oil pump to the oil barrel. After cleaning, put it into the gun washing water for circulation cleaning, as above. (if the paint contains curing agent or Pu oil, the gun washing water can't be recycled, just use once. Avoid gun washing water and paint to produce curing agent to solidify in oil pipe and oil pump).
