NOTE: If too much grease is applied, excess grease may scatter around during machine’s running. Apply proper

amount so that thin coat of grease is made over the surface.

NOTE: If grease is applied on the ball screw surface (out of ditch), the grease will be coming out, not being caught

by ball bearing inside. That may cause insufficient lubrication condition. Then Apply grease onto the ditch

of the ball screw.

① Perform “Ageing” in Manual > Warm Up with the less than 20% axis speed for more than 10 minutes.

Speed setting can be done by sliding the “Axis Speed” gauge at [Setting] tab.

② Then wipe off the pushed-out dirty grease with a nonwoven cloth and apply new grease into the nut

again.

③ Remove excessive grease gathered on the nut or both ends of the ball screw with a nonwoven cloth,

and perform “Ageing” by increasing axis speed gradually.

④ By Axis command in Manual Menu, move the Head Assy. from an end of axis to the other end for

several times, so that the applied grease is spread over whole of the work range. However, the spread

grease cannot reach the actual end of each axis because of the out of work range of the nut. Then add

some grease there by hand with a nonwoven cloth etc.

NOTE: If a cotton-swab or a woven cloth is used to wipe off the dirty grease, waste threads of cloth may be caught

in the ball screw. Use a nonwoven cloth.

NOTE: Use proper grease for lubrication, specified as our standard. (See the “Specified Lubricants” list at the end

of this chapter.)

NOTE: Remove the excess grease gathered on the nut or both ends of the ball screw by wiping it off with a

nonwoven cloth to avoid grease scattering.

■ Application of grease on a Nozzle Holder

【Steps】

⑧ Rub the inside of the Nozzle Holder with materials like a dry cotton swab to clean out the grime, such

as old grease.

⑨ Use the head vacuum breaker to blow out the dust, such as fibers from a cotton swab.

NOTE: The head vacuum breaker can be executed by clicking the button at required head on the window of Main

Menu > Manual Menu > Actuator > On/Off > Head Vacuum.

⑩ Apply silicon grease evenly on the new cotton swab and rub the inside of the Nozzle Holder softly and

evenly with it.

⑪ After grease is applied, insert a nozzle and confirm that the nozzle escaping works smoothly.
