INTRODUCTION
All the machines 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
machines 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.
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.
