3. About this manual
Descriptions in this manual stress important maintenance items that are essential for maintaining
equipment performance. Information given here mainly describes making inspections, cleaning and
greasing as well as procedures for replacing consumable parts in each location given in a step-by-step
format. This manual is comprised of the following chapters.
Chapter 1 Maintenance
Describes conditions and environments to use for maintaining equipment performance. The importance of making daily
checks and performing cleaning tasks is explained. Setups to make before starting maintenance work, consumable parts
and maintenance tools as well as the necessary tools are also described.
Chapter 2 Daily maintenance items
Making checks and cleaning the machine are essential daily maintenance tasks for maintaining equipment performance.
Performing these tasks prevents unforeseen trouble and allows using the machine in an optimum state.
Chapter 3 Periodic maintenance items
Describes maintenance tasks that should be performed periodically to maintain equipment performance. Includes periodic
maintenance intervals such as for “weekly or biweekly”, “monthly or bimonthly” and “6 month” maintenance tasks.
Chapter 4 How to replace consumable parts
Describes methods for replacing parts subject to constant wear such as nozzle leaf springs and ejector valves.

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
■ Air
• Use correct air pressure of 0.55 MPa (5.5Kgf/cm
2
) and an air consumption rate of 60 liters a minute (ANR).
• Use an air hose with an inner diameter (I.D.) of 3/8ths of an inch.
• Use clean air obtained via an air dryer and air filter.
■ Power
Power supply : 200 to 240VAC single phase (-10%, +6%)
Frequency : 50 Hz or 60 Hz
Rating : 2.8 kVA
Power supply connection : Power supply cable AWG13 (conductor cross section: 3.5 mm
2
minimum)
■ Environment
Noise : 1500V for a maximum of 1 µs
Humidity : 20 to 90% (no condensation)
Temperature : Functions guaranteed within 15 to 35°C. Machine precision guaranteed within 20 to 28°C.
Atmosphere : No dust or powder. No significant noise generation.
Installation : Flat level location sturdy enough so no vibration occurs during operation.
Wooden floors in particular are unsuitable.
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. We strongly recommend
you perform periodic inspections and cleaning to ensure the machine is used under optimal conditions.
