IMPORTANT : During the lubrication procedure, inspect the bearings and ball screw for any
damage or signs of wear.
DANGER : Use extreme caution when you operate the stage without the hardcover.
1. Drive the stage table to one end of travel and remove power to the stage.
2. Remove the cover attached to the rear end plate on the side opposite of the motor (
Figure 4-1 ).
3. Remove the hardcover screws ( Figure 4-2 ).
4. Carefully slide the hardcover away from the stage ( Figure 4-3 ). This can be done without removing the
table.
5. Remove any accumulated dust or debris from the inside of the assembly.
6. Remove any dirty or dried lubricant from the ball screw.
l
Use a clean, lint-free cloth with a side-to-side motion.
l
Use a swab soaked in Isopropyl Alcohol to remove stubborn debris.
7. Move the stage to the opposite end of travel. If the stage has an optional brake, the stage cannot be
moved by hand.
l
If the stage has a brake: restore power to the stage, drive it to the desired position, then remove
power
l
Redo Steps 5 and 6 for any areas covered by the previous table position.
8. Clean the end of the ball-screw nut and wiper with a clean, lint-free cloth or swab.
9. Clean the linear bearing guides with a clean, lint-free cloth or swab.
10. Apply a thin, continuous film of lubricant to the ball-screw threads and linear bearing guides. Aerotech
recommends that you use a good quality, natural bristle artist's brush.
11. Move the stage to the opposite end of travel. If the stage has an optional brake, the stage cannot be
moved by hand.
l
If the stage has a brake: restore power to the stage, drive it to the desired position, then remove
power.
l
Redo Steps 8 through 10 for any areas covered by the previous table position.
12. Refasten the hardcover. First Generation Stages Only : Torque the hardcover screws to 36 - 42 in-lbs
to ensure proper support.
IMPORTANT : For GEN II PRO series stages with travel lengths greater than or
equal to 800 mm . The hardcover mounting surfaces in the stage end plates have been
machined in such a way as to negate the natural sag due to gravity of the hardcover. As the
mounting screws are tightened, the cover gently conforms to the shape of the end plates.
Ensure that the cover is fully seated on the end plate mounting surfaces before you
operate the stage. Check each mounting screw for full engagement by tightening the screw
while holding the long side of a standard hex wrench.
13. Restore power to the stage and drive the stage table back to its original position to redistribute lub-
ricants.
