CAUTION
Wear eye protector and rubber gloves
when handling the engine coolant. If
contact with the eyes or skin should
occur, fl ush eyes and wash immediately
with clean water.
NOTICE
Do not remove the radiator cap.
(1) Make sure the machine is level.
(2) Make sure the engine and all systems
are turned off and the emergency stop
buttons are depressed.
(3) Check the level of engine coolant in the
reserve tank (fi g. 7‒5, 1). When the engine
is cold, the coolant level in the tank should
be at or slightly above the “LOW” (COLD)
mark (fi g. 7‒5, 2) on the coolant reserve
tank. If the coolant level is at the “FULL”
(HOT) mark (fi g. 7‒5, 3) when the engine
is cold, the coolant will expand when it
becomes hot and possibly spray out of the
overfl ow hose.

(4) Add additional engine coolant to the
reserve tank if necessary.
(5) Check the radiator hoses (fi g. 7‒5, 4) for
cracks, abrasions, cuts or other damage.
Replace as necessary.
(6) Check the hose (fi g. 7‒5, 5) that connects
the reserve tank (fi g. 7‒5, 1) to the radiator.
Be sure it is securely connected and there
are no cracks or damage. If the hose is
damaged, engine coolant will leak out
instead of going into the reserve tank.
Periodic Maintenance
3.
WARNING
Periodic maintenance shall be
performed by qualifi ed service
technicians.
Monthly and Annual
3‒1
Inspection
• Perform a monthly and annual inspection
referring to the separate service manual.
‒ Depending on the laws of the country in
which the machine is being used, keep
the records of the checks for the required
number of years.
‒ For any doubts you may have about
handling, inspection or spare parts,
contact AICHI or AICHIʼs dealer.
‒ Refer to the separate service manual for
what must be checked regularly.
• If the machine has not been used for over
one month, make sure to perform the
monthly inspection before use.
Crawler Tracks
3‒2
As slack will form on the crawler tracks due
to friction etc., periodically adjust the tension
of the tracks. If the tension is not appropriate,
track detachment may occur.
WARNING
• Do not get on the platform while
adjusting the tracks. Failure to avoid this
hazard could result in a fall accident and
serious injury.
• Do not enter under the platform, boom,
tracks, and chassis while adjusting the
tracks. Failure to avoid these hazards
could result in crush accidents and
serious injury.
Adjustment Method
3‒2‒1
Set up the machine on a fi rm level surface,
retract the boom fully.
Rotate the boom to the right or left side so
that it is at right angles with the chassis.
