1. Cause and Remedy of Simple Trouble
•
In principle, the machine should be operated
by only one person for troubleshooting.
If there are more than one, ensure good com-
munication by giving loud verbal instructions.
•
Troubleshoot the machine carefully, protect-
ing your hands from moving mechanisms
when the machine is powered up.
•
When the [OPERATION/SET UP] switch is
set to the "SET UP" side, it becomes pos-
sible to operate the machine with the main-
tenance cover open. Be sure to pay a spe-
cial caution while operating the machine.

Vacuum Pressure System
Check whether the vacuum pressure is correctly adjusted. *1
Set the operation mode to “PLACE” by pressing the [PASS/PLACE
CHANGE] key at the “AUTO OPN. SUB-MENU” display and turn
off all vacuum valves ([LA1-AXIS VACUUM/VACUUM BLOW],
[LA2-AXIS VACUUM/VACUUM BLOW], [LB1-AXIS VACUUM/
VACUUM BLOW], and [LB2-AXIS VACUUM/VACUUM BLOW]
Keys).
Confirm that “OFF” is set in the “STATUS” text boxes at the
“MANUAL SUBSYSTEM OPERATION” display.
Confirm that the vacuum pressure is -93 kPa (70 cmHg) or more
(Vacuum valve fully closed).
When the vacuum pressure is too low, it is required to replace the
vacuum pump with a new one.
Consult our sales personnel for the detailed information on how to
replace or repair the vacuum pump.
Check whether the vacuum pump is producing any abnormal sound. *2
Catch the sound of the vacuum pump and confirm that the sound is
not abnormal.
When abnormal sound is produced, consult our sales personnel for
