Maintenance
Before beginning work
In most cases, maintenance should be performed with the main power turned off.
However, some maintenance tasks are performed under emergency stop conditions with the power turned on.
In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance.
The power is turned on during maintenance where any servo-axis must be operated or machine operation
checked. In this case, also ensure adequate safety before beginning the maintenance.
When operating the machine, make sure the following conditions are met.
n
Operating conditions
1. Supply air pressure is kept at correct pressure.
2. All safety covers are closed.
3. Power cable is correctly connected.

Maintenance
1. Maintaining machine performance
The most important condition essential for maintaining the performance of the machine you purchased is
using it under good environmental conditions. Performing daily maintenance and periodic inspections is also
absolutely essential.
1.1 Essential conditions and working environment
n
Air
• Correct air pressure of 0.4MPa and air consumption of 24 liters/min (ANR) must be maintained.
• Use an air hose with an inner diameter (I.D.) of 3/8ths of an inch and a Hi Cupla (30SH) made by Nitto Kohki or an
equivalent air coupler.
• Use clean air obtained via an air dryer and air filter.

Environment
Item Description
Humidity
20 to 90% (no condensation), optimal range: 50 to 60%
To prevent electrostatic charge, keep the humidity above 40%.
When using an industrial humidifier, use water equivalent to pure water.
Temperature Functions guaranteed within 15 to 35°C. Machine precision guaranteed within 20 to 28°C.
Atmosphere
No dust or powder. (The number of dust particles of more than 0.5 μm in diameter should
be less than 100000/feet
3
) No organic solvent vapor, sulfurous acid gas, chlorine gas
and flammable gases, etc.
Installation floor condition
Flat level location sturdy enough so no vibration occurs during operation.
Wooden floors in particular are unsuitable.
Floor load-bearing strength should be 1050 kg/m
2
or higher.
For load-bearing strength, consult a professional contractor who is familiar with the
installation location with information on the equipment weight, floor space, positions for
adjuster feet, etc.
1.2 Importance of periodic inspections and cleaning
Periodic inspections and cleaning are extremely important maintenance tasks to maintain the machine’s
performance.
Failure to perform inspections and cleaning will prevent the machine from delivering full performance and may
lead to inspection errors or equipment breakdowns.
Examples:
• 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. We strongly recommend
you perform periodic inspections and cleaning to ensure the machine is used under optimal conditions.
