CAUTION
M1046983 04/08
Replacing a caster requires at least two people to maneuver and tip the machine.
Personal injury and/or machine damage is possible if one person attempts this
procedure alone.
1. Disconnect all pipeline hoses from the wall and the machine, close all gas cylinders,
unplug the power cord, and set the system switch to standby.
2. Remove the absorber, the Aladin cassettes, gas cylinders, drawers and all auxiliary
equipment.
To prevent damage, do not tip the Aisys machine more than 10 degrees from
vertical.
3. Block the opposite wheels; then, block up the machine until there is enough room to
remove the defective caster.
To block up the machine, tip and slide blocks under the caster base. Raise both
sides evenly until the unit is high enough to remove the caster.
4. The casters are threaded into the base
and held with a Loctite compound.
Remove the caster with an
appropriately sized open-end wrench.
5. If required, clean the threads of the new
caster with denatured alcohol.
6. Apply Loctite 242 to the threads of the
new caster. Install the caster securely
into place.
7. Make sure the caster turns freely.
8. Carefully lower the machine to the floor.
9. Perform the checkout procedure (Section 3).
