Lubrication Operation
f
NOTE:
Lubricating operation is a series of warm-up, travel, swing and digging operation carried out repeatedly for a few cycles
at slow speed.
Lubricants will deteriorate during long term storage of the machine. Be sure to carefully check the lubricants before
restarting operation of the machine.
Precautions for Disconnecting or Connecting Batteries
In case the batteries are kept disconnect for more than one month or the battery disconnect switch is turned off, data
in the information controller or preset data of the radio may be initialized.
Contact your nearest Hitachi dealer before restarting operation of the machine after the batteries are disconnected for
one month or more.
STORAGE
Precautions for Long-Term Storage
Wash the machine. Remove soil or other debris adhered to the machine.
Check lubricant's level and contamination. Fill up or change if necessary.
Lubricate all grease points.
Coat grease to exposed metal surfaces which are subject to rust.
(i.e. cylinder rods etc.)
Remove the batteries and store them in a dry protected place after charging fully. Turn the
battery disconnect switch to the OFF position.
Add anti-rusting agent. If storing in extremely cold areas, either add extra anti-freeze or
drain coolant completely to avoid freezing. In this case, place a sign reading "NO COOLANT".
Store the machine in a dry storage area using a protective cover.
Inspect and repair, then store.
If oil film on the metal surfaces is lost, rust may begin, possibly causing abnormal wear
of the machine when the machine operation is restarted. If the machine is stored for a
long time, operate hydraulic functions for travel, swing and digging two to three times
for lubrication, at least once a month. Be sure to check the coolant level and lubrication
conditions before operating.
