WA470-6H – VEAM946100
Maintenance of air conditioner
!
If air conditioner refrigerant gets into your eyes, it may cause
blindness; if it touches your skin, it may cause frostbite.
!
Never touch refrigerant.
Compressed air
!
When carrying out cleaning with compressed air, there is a
hazard of serious injury caused by flying particles.
!
When using compressed air to clean elements or the radia-
tor, always wear safety goggles, dust mask, gloves, and
other protective equipment.
Periodic replacement of safety critical parts
!
In order for the machine to be operated safely for a long
time, it is necessary to add oil and to carry out service and
maintenance at periodic intervals. In order to further
increase safety, components with a strong relationship to
safety, such as hoses and seat belts, must be replaced at
periodic intervals.
Replacement of safety critical parts: See "Periodic replace-
ment of safety critical parts (4-25)".
!
The material of these components naturally changes over
time, and repeated use causes deterioration, wear, and
fatigue. As a result, there is a hazard that these components
may fail and cause serious injury or death. It is difficult to
judge the remaining life of these components from external
inspection or the feeling when operating, so always replace
them at the specified interval.
!
Replace or repair safety-critical parts if any defect is found,
even when they have not reached the time specified interval.
!
Replace all hoses every 2 years at the latest. The shelf life of
the hose should not exceed 2 years.
