1.2 Importance of periodic inspections and cleaning
Periodic inspections and cleaning are extremely important maintenance tasks. Failure to perform inspections
and cleaning will prevent the machine from delivering full performance and may lead to component mounting
problems or equipment breakdowns.
Examples:
• Dirty nozzles might cause mistakes in component recognition and cause mounting errors.
• Dirty air paths may cause numerous pickup and mounting errors.
• Inadequate feeder and feeder plate inspections may cause pickup errors.
• Dirty optical system (camera, lighting, etc.) may cause recognition errors.
• Poor greasing of axes may cause abnormal noises.
• Poor inspections such as of valves may cause errors in PCB clamping and conveying.
As these examples show, failure to make inspections may lead to equipment problems. It is strongly
recommended to perform periodic inspections and cleaning to ensure the machine is used under optimal
conditions.

NOTE
The "inspection check sheet", a list of inspection items is included at the end of this manual for effective inspection.
Use the check sheet when inspecting.
1.3 Importance of appropriate humidity management
The inappropriate humidity management of the machine installed floor, it triggers dew drops and may damage
the control circuit inside of machine.
Perform the following itmes to secure machine endurance.
n
Check the temperature and humidity of your site before turning on machines.
• Actuate the air conditioner, humidifier or dehumidifier to adjust the temperature and humidity matched to the
environmental condition described in "1.1 Essential conditions and working environment", confirm the temperature
and humidity of your site settle and then turn on machines.
n
Use the humidifier adequetly.
• Use the water without much impurity for humidifier.
• The spray type humidifier should be installed at high place enough from machines. Adjust the amount of mist to
prevent the dew drops on machine surface.
• Adjust the humidifier operation as necessary. Especially the using of humidifier in humid period, the humidity may
excess 80%.
TIP
The water without much impurity refers to that is filtered by the dedicated equipment.
The impurity amount of filtered water can be perceived by the electrical conductivity of water (S/cm);
General tap water in Japan: 100 - 400 μ
S/cm
Filtered tap water: approx. 1 - 2 μ

CAUTION
For your humidifier, DO NOT use tap water or well water. Those water include small amount of elements as such
Natrium or Chlorine, may cause a decline of insulation, and it may damage the circuit inside of machine.

2. Preparing for maintenance tasks
Tasks described in this section focus mainly on replacing parts (consumable parts) that might cause a gradual
loss of machine functions during use. This section also describes how the user can easily replace parts
(replaceable parts) when a breakdown occurs.
