a. Remove the 10 screws that secure the
Zaxis cover to the Zaxis module.
b. Carefully pull up vertically to remove the
Zaxis cover.
NOTE: Removing the four (4) screws near
the bottom of the Zaxis cover releases
the Zaxis bottom plate; place your hand
underneath the plate to catch it.

Clean and Grease the ZAxis Components (R / RV Series Only)
2
Clean the Zaxis as follows:
a. Use a clean nonwoven cloth to clean any
dust and grease from the Zaxis ball screw,
spring, spring shaft, and Raxis ball spline.
b. Pull the Zaxis head down, exposing
all components listed above that were
previously inaccessible, and clean the dust
and grease with the nonwoven cloth.
NOTE: Keep the Zaxis head in the down
position.
c. Use the brush and grease from the
maintenance grease kit to liberally apply
grease to the Zaxis ball screw, spring,
spring shaft, and Raxis ball spline.
d. After greasing, release the Zaxis head from
the down position and move the Zaxis
module up and down to disperse the grease
evenly on each component.
e. Use a clean nonwoven cloth to remove
excess grease.

rotational shafts previously inaccessible
and clean the grease and dust with the
nonwoven cloth.
NOTE: Keep the Raxis in the rotated
position.
c. Use the brush and grease from the
maintenance grease kit to liberally apply
grease to the rotational ball screw and
rotational shafts.
d. After greasing, release the Raxis from the
rotated position and then rotate the Raxis
