GOGGLES TO ENSURE THE GREASE WILL NOT COME IN CONTACT WITH THE EYES.
w
WARNING
INFLAMMATION MAY OCCUR IF THE GREASE OR LUBRICANT COMES INTO CONTACT WITH SKIN. BE SURE TO WEAR
PROTECTIVE GLOVES TO PREVENT CONTACT WITH SKIN.
w
WARNING
DO NOT TAKE ORALLY OR EAT THE GREASE OR LUBRICANT. EATING WILL CAUSE DIARRHEA AND VOMITING.
n
Cautions
c
CAUTION
Always stop the machine before installing the parts feeder into the machine. Hands or other parts of your body might
otherwise be caught in the moving parts.
c
CAUTION
During operation only press the emergency stop button in cases of emergency.
c
CAUTION
Always turn off the power with the correct procedure. Using hasty or incorrect procedures to turn off power might
damage the flash disk in the machine.
c
CAUTION
When installing push-up pins on the push-up plate, set them in positions where they will not interfere with the conveyor
rails or other parts when the push-up plate is raised.
c
CAUTION
When the machine you are using is not equipped with a nozzle station, you must change the nozzle by hand if it is not
a specified nozzle. In this case, always first press the emergency stop button.
c
CAUTION
If an abnormality occurs during warm-up, immediately stop the machine, find the cause of the problem and eliminate it.
c
CAUTION
When storing the grease after use, tightly close the cap of the grease tube or container to prevent dust and moisture
from entering inside. Store it in a dark place to avoid direct sunlight, and keep away from fire and heating sources.
c
CAUTION
After copying board data or system data into a USB flash memory, do not leave that data in the USB flash memory for
a long time. Use the USB flash memory just as a copy medium for backup data. Prepare other backup media
(CD, DVD, MO, etc.) to store backup data more safely.
c
CAUTION
You can also clean and grease the ball screw after removing the push-up plate. However, the push-up plate is heavy.
So, take great care during handling.
c
CAUTION
A strong air flow is exhausted during the cleaning blow. Always remove all nozzles attached to the heads before
starting the cleaning blow. Starting the cleaning blow while the nozzles are still attached may blow the nozzles away
from the heads causing the nozzles to break or become lost.
