4.5.3 Lubricating the spline shaft (as needed)

NOTE

Basically, the lubricating the spline shaft (Z-axis) is not required. However, the grease on the spline shaft surface is

removed by touching with hand or by sprinkling solvent. As a result, the spline shaft gets easily rusted. Apply the

speciﬁed grease (NSL) slightly for anti-rusting as needed.

Move the head unit.

1. Press the emergency stop button and

then open the machine safety cover.

2. Move the head unit forward.

Remove the head cover.

Remove the fixing bolts (six locations) of the

head cover with the hex wrench (3).

Be aware that a loud air exhaust sound is heard when

disconnecting the air coupler. Use care to prevent oil,

water, and impurities, etc., from being sprayed out.

Check the inside of the filer cup.

Check if oil or water is in the cup. When oil

or water is dirty, clean it by following Step 3
