SYSTEM TROUBLE SHOOTING
9.1 INTRODUCTION
All the machines being manufactured by COSEN pass a 72 hours continuously running test
before shipping out and COSEN is responsible for the after sales service problems during the warranty
period if the machine are used normally. However, there still exist the some unpredictable problems
which may disable the machine from operating.
Generally speaking, the system troubles in this machine model can be classified into three
types, namely GENERAL TROUBLES, MOTOR TROUBLES and BLADE TROUBLES. Although
you may have other troubles which can not be recognized in advance, such as malfunctions due to the
limited life-span of mechanical, electric or hydraulic parts of the machine.
As a twenty year old company, COSEN has accumulated enough experiences and technical
data to handle all of the regular system troubles. Meanwhile, the engineering department of COSEN
had been continuously improving the machines to prevent all possible troubles.
It is hoped that you will give COSEN your maintenance experience and ideas so that both
sides can achieve the best performance.
