DISASSEMBLING
(1) Understanding operating procedure
Read OPERATION & MAINTENANCE MANUAL
carefully to understand the operating procedure.
(2) Cleaning machines
Remove soil, mud, and dust from the machine
before carrying it into the service shop to prevent
loss of work efficiency, damage of parts, and diffi-
culty in rust prevention and dust protection while
reassembling.
(3) Inspecting machines
Identify the parts to be disassembled before start-
ing work, determine the disassembling procedure
by yourself considering the workshop situations
etc., and request procurement of necessary parts
in advance.
(4) Recording
Record the following items for communication and
prevention of recurring malfunction.
1) Inspection date and place
2) Model name, applicable machine number, and
hour meter read
3) Trouble condition, place and cause, if any
4) Visible oil leakage, water leakage and damage
5) Clogging of filters, oil level, oil quality, oil contami-
nation and loosening of connections
6) Result of consideration if any problem exists based
on the operation rate per month calculated from
hour meter indication after the last inspection date.
(5) Arrangement and cleaning in service shop
1) Tools required for repair work.
2) Prepare space to place the disassembled parts.
3) Prepare oil containers for spilling oil etc.
1.2 SAFETY IN DISASSEMBLING
AND ASSEMBLING

1) Do not disassemble, reassemble or modify the
hydraulic equipment without the permission of the
manufacturer, who is not responsible for the
performance and function of the product after
reassembling.
2) When disassembling and reassembling for un-
avoidable reason, refer the work to qualified
