10 MAINTENANCE
This chapter provides the operator with the additional in-
formation needed to properly operate and maintain the
machine and is only intended to assist the operator in
performing routine maintenance tasks. For more com-
prehensive maintenance instructions, please refer to the
Inspection and Preventive Maintenance Schedule
and the Maintenance Manual.
10.1 LUBRICATION
In order to ensure the performance and service life of
the machine and its components, the moving parts must
be regularly inspected and lubricated.
NOTICE
• Mixing lubricating oil of different grades will
change its property, and bring damage to the ma-
chine. When adding lubricating oil, the oil to be
added must have the same grade as that of the oil
being used by the machine.
• Using lubricating oil mixed with dust can lead to
premature wear of the sliding surfaces and short-
en the service life of the machine. Before adding
lubricating oil, the oil cup and other surfaces must
be cleaned.
• Failure to comply with lubrication intervals or lack
of lubrication can cause machine damage and in-
crease repair costs and downtime.
• During machine lubrication, unrelated person-
nel are prohibited from operating the machine,
because accidental operation of the machine
may bring serious danger to the operator.
• If lubricating oil gets into the eyes, rinse the
eyes immediately with clean water and seek
medical attention in time. If the skin comes into
contact with lubricating oil, make sure to thor-
oughly wash the skin with water.

Lubrication intervals are based on machine usage under
normal operating conditions, and if the machine is used
in harsh conditions (such as dusty environments) or ab-
normal conditions, the inspection and lubrication should
be performed more frequently.
