Cylinder Replacement
When you check the column balance, if you find that gas needs to be added fre-
quently, you may need to replace one or more of the three cylinders in the col-
umn.
Remove the yellow dust caps and test each cylinder with a pressure gauge. If
one or more cylinders is low relative to the others, use the following procedure
to replace it.
1. Lower the column to minimum height and power down the pedestal.
2. Fully discharge the gas from the cylinders using the procedure in chapter 3.
3. Remove the payload and head from the pedestal. Refer to the documenta-
tion for the payload equipment and the User Manual for the pan/tilt head
for specific instructions.
DANGER: DO NOT REMOVE THE SCREWS IN STEP 4 IF
THE COLUMN IS PRESSURIZED. YOU CAN CAUSE
SERIOUS INJURIES AND DAMAGE TO THE PEDESTAL.
4. Use a 3 mm hex key to remove the four socket head cap screws from the
top plate over the cylinders being replaced. Set the top plate and screws
aside.
5. Remove the cylinder from the column.
