2.操作准备
（1） 试擦机器
机头装箱前为了防止机件生锈，各部分均涂有
较厚的防锈油脂，同时机头装箱后，还可能在较长
的贮藏和长途运输阶段造成油脂硬化和积聚在机器
表面的灰尘，所以必须将表面的油脂和灰尘用汽油
和洁净的软布试擦干净。
（2） 检查
机器出厂时，虽然经过周密的检查和试验，但
在长途运输中也可能受到强烈的振动使机件松动或
歪曲，所以应该作一次周密仔细的检查，并用手轻
轻转动主动轮，看机件之间有无转动困难，碰撞现
象或其它不均匀的阻力，不正常的声响，如有应做
适应的调整，机器情况正常后才可正式试车。

2.PREPARATION
Cleaning the machine
（1）
Before leaving the factory, the machine parts are coated with
rust-preventive grease, which may be hardened and contami-
nated by dust during storage and shipment. This grease must
be removed with gasoline.
Examination
（2）
Though every machine is confirmed by strict inspection and test
before leaving the factory, the machine parts may be loose or
deformed after long distance transportation with jolt. A
thorough examination must be performed after cleaning the
machine. Turn the balance wheel to see if there is running
obstruction, parts collision, uneven resistance or abnormal
noise. If these exist, adjustment must be made accordingly
before run-in operation.
