Daily maintenance items
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.

1. Checking the nozzle
Solder sticking to the nozzle tip or a clogged nozzle hole can cause component pickup errors and
recognition errors. Poor nozzle spring action can also cause pickup and mounting errors. To prevent such
problems periodically inspect and clean each nozzle.
