1. Outline of Maintenance

This session describes how to perform inspections, cleaning, lubrication,

and adjustment to keep the machine in good shape. It is recommended that

periodic maintenance of the machine should be ensured.

1.1 Notes on Maintenance

WARNING

• Only qualiﬁed personnel should perform the maintenance

work carefully for the machine in compliance with the speciﬁed

instructions.

•

It is highly dangerous for either the power or air supplies to be

turned on by other people during maintenance.

Before performing any maintenance work, be sure to lock the

power breaker and the air source with padlocks.

Power Breaker :

Set the power breaker to the "OFF" side and

lock it with a padlock.

Air Source : Stop the air supply and set the main valve to

the "SHUT" side. After that, be sure to lock it

with a padlock.

• Designate a person who can have charge of the padlock keys.

• If the provided padlock is lost or damaged, purchase its

substitute.

Note

Preliminary preparation is required for some maintenance tasks with the

power being supplied.

Check each maintenance method.

Although the load power to the motors, etc., is turned OFF when the door

is opened, the maintenance must be performed carefully because you have

to put your hand(s) inside the machine.

CAUTION

Even when the power breaker is set to "OFF", the primary line is

powered, making it possible to cause an electric shock.

Be sure to completely stop the power supply to the machine before

maintenance work.

Residual voltages may remain behind for a few minutes in the

internal devices of the machine after power interception.

Before performing maintenance work, wait until the charge lamps of

the DC power supply and the servoampliﬁer go "OFF" in 10 minutes or

more after the power breaker is set to "OFF".

1.2 Preparation for Maintenance

1.2.1 Preparation for Cleaning

•

Greasing Brush

Use a brush whose bristles do not come off if possible.

•

Rag (a waste piece of cloth)

Use a rag made of such material as cotton, etc., that produces as less waste

thread as possible.

A clean rag is also required, depending on the spots to be cleaned.

Notice

The remaining waste thread if any will cause the machine to break

down.

•

Oiled Rag

Use a rag made of such material as cotton, etc., that produces as less waste

thread as possible.

Too much grease should not be applied and any different type of grease

should not be mixed into the speciﬁed one.

Notice

The remaining waste thread if any will cause the machine to break

down.

•

Air Gun

Do not use the air gun for any spots other than the speciﬁed ones.

If dirt and dust are dispersed, they may adhere to the sensors and moving

mechanisms, causing the machine to break down.
