 While handling harmful material, such as
lubricant, fuel, and coolant, melting agent, filter,
storage battery and other materials, obey
relevant laws.
Repair and Check after Maintenance
Unexpected problems may occur if the proper
checks and maintenance procedures are not
performed. It may even damage the machine
or cause injuries, and so pay attention to the
following issue.
 Checking when the engine is off
1. Are all repair and maintenance parts
checked?
2. Are repair and maintenance items
correct?
3. Are there tools or parts dropped into
the machine? It is dangerous if they are
wedged into the linkage systems of the
control levers?
4. Is the leaking water or oil repaired?
Are the bolts screws down?
 Checking when engine running
Pay attention to safety and the following items:
1. Do the repair and maintenance parts
work normally?
2. Does the hydraulic system leak oil
when the engine running, speeding up or
adding load?
Tires
Handling of Tire
If a tire or a rim is handled in a wrong way, the
tire may burst or may be damaged and the rim
may be broken and scattered, which can
cause serious injury or death. For the safety of
maintenance workers, comply with the flowing
proceedings.
 Since maintenance, disassembly, repair
and assembly of the tires and rims require
special equipment and skills, be sure to ask a
tire repair shop to carry out the work.
 The specified tires must be used; inflate
them to the specified pressure. The stated tires
and pressure are in the "Tires" section in the
Maintenance chapter.
 When inflating a tire, check that no one will
enter the working area. And use an air chuck,
which has a clip and can be fixed to the air
valve. While inflating the tire, check the
inflation pressure occasionally so that it will not
rise too high.
 If the rim is not fitted normally, it may be
burst or deflate
while the tire is
being inflated. To
ensure safety,
place a guard
around the tire
and do not work
in front of the rim
but work on the
tread side of the
tire.
 Abnormal
drop of inflation
pressure and
abnormal fitting of the rim indicate trouble in
the tire of rim. In this case, be sure to ask a tire
repair shop to carry out repairs.
 Do not regulate the inflation pressure after
working at high speeds or high loads.
 Explosions of air-inflated tires have
resulted from heat-induced gas combustion
inside the tires. Explosions can be caused by
heat that is generated by welding, heating rim
components, external fire, or excessive use of
brakes.
 The energy of tire explode are stronger
than deflation. Explode can make tire rim and
parts of transmission fly out more than 500
meter. It can arouse loss of property and
personnel.
 It is recommended to fill tire with N2. If the
tire has original air, it is suggested that
nitrogen should be used to adjust the pressure.
The nitrogen can be mixed with air. The tires
inflated with nitrogen gas can prevent the tires
from exploding because N2 is inflammable.
The N2 can prevent from oxidation, aging of
rubber and cauterization of rim parts.
