1、 更换空滤：拆卸空气过滤器外罩尾部螺丝、取下外罩尾部，拆卸空气过滤器锁紧螺丝，取出空气过滤器，将新过滤器装入，按反步骤装回过滤器及外罩。 1, replace the air filter: remove the air filter cover rear tail a screws, remove the cover, remove the air filter lock screw, remove the air filter, the new filter into, according to the steps back to the filter and housing. 2、 更换油滤：用专用工具锁紧过滤器底部正向旋转拧开过滤器，用干净的布条清洁过滤器底坐并涂上少许机油，在新机油过滤器的密封圈上涂上少许机油，装上新过滤器，并用专用工具锁紧。 2, replace oil filter: use a special tool rotation lock at the bottom of the filter is turned on filters, with a clean cloth to clean the filter bottom sit and coated with a little oil, the new oil filter on the sealing ring coated with a little oil, put on the new filter, lock with specialized tools. 3、 更换油分：方法与更换油滤相同。 3. Oil replacement: the method is the same as changing oil. 4、 更换润滑油：油的温度在30至60℃时粘度会降低并且不会烫手，同时也利排净机组的残油。所以在换油时如是冷油，先开机运行2—3分钟。换油时应确保机组无压力才可进行。先拆开油气分离桶注油螺母、用合适的容器准备装残油。打开桶部下面的排油阀，排油时时而用手正盘机头皮带轮以利将储在机头内的油也排出。待油彻底排完后，关闭排油阀。注入新润滑油，注油时时而用手反盘机头皮带轮以利将油吸入管道及机头。注油量在浸过油位镜后再注入2~3cm（此为经验值，实际油位需在开机并加载状态时观测），注好油后，装上注油螺母并锁紧，拆下进气阀，从机头进气口注入少量润滑油，油量在浸没转子的三分之二处即可，装上进气阀。清洁空压机各部件表面。 4, replace lubricating oil: oil temperature in 30 to 60 ℃ when viscosity decreases and not hot, but also the row of net residual oil of the unit. So when oil is changed, the oil is cold, and the first two - three minutes. Oil change should ensure that no pressure on the unit can be carried out. First, disassemble oil and gas separation bucket filling nuts and prepare the residual oil with suitable container. Open the drain valve on the bottom of the barrel and drain the oil from time to time. The oil in the nose will also be discharged from the nose. Shut off the drain valve when the oil is finished. Inject new lubricating oil, lubricate the oil, and use the hand counter pulley to remove oil suction pipe and head. Oil quantity in oil soaked in a mirror injection again after 2 ~ 3 cm (this is experience value, the actual oil level should be in the starting and loading state observation), after good oil injection, mount nut and lock filling, remove the inlet valve, air inlet from the injection of a small amount of lubricating oil, oil amount in the two-thirds of the submerged rotor, aspirant valve. Clean air compressor parts surface.
