2.1.3 Lubricant
z
Lubricant is used to reduce noise and prevent wear on the joint surfaces.
z
Joints not included in the manual (connectors, jointing sleeves) are treated during overhaul. So
they do not need be lubricated. When some parts become inflexible because of long-term
operation, it is necessary to add lubricant.
z
Remember to wipe off the overflow lubricant when adding it.
2.1.4 The Storage of Oil and Fuel
z
Prevent water, dirt or other impurities from mixing with the oil.
z
Follow the rule, first in first out, to maintain oil quality during long-term storage (Use the oil with
the longest shell life).
2.1.5 Filters
z
Filters are extremely important safety components. They can prevent impurities in the fuel from
entering important equipment and causing problems. Replace all filters periodically. For the
maintenance cycle, refer to 3 CONTENT OF MAINTENANCE in this chapter. Replace filters
at shorter intervals when the machine works in a severely bad environment.
z
Never try to clean paper filter elements and use them again. Always replace them with a new
one.
z
When replacing the oil filters, check whether there are some metallic particles adhering to the old
filter. If some metal particles are found, consult the maintenance people.
z
Never open the packs of new filters until they are used.
z
Always use authorized filter parts.
