The counterbalance air spring and rod ends should be replaced every two (2)
years.
1. Verify that the Axis is at 0 degrees before beginning. Press E-stop before
doing any disassembly.
2. Remove sheet metal cover and lo osen the two 3/8-16 SHCS (1).
3. Back out the 1/4-20 SHCS (2), and tighten the two 3/8-16 SHCS (1) this will
keep the pre-load cam secure while the next step is accomplished.
4. Remove 3/8-16 SHCS that mount Air Spring and Rod Ends (3).
5. Tighten the rod ends onto the Air Spring and secure the Air Spring using the
two 3/8-16 SHCS removed in step 4.
6. Slightly loosen the 3/8-16 SHCS (1). Screw in the 1/4-20 SHCS to force pre-
load cam counterbalance down (this will push the air spring inward). Tighten
this adjusting bolt until the slots in the cam have contacted the tops of the
mounting bolts. Tightening the two 3/8-16 SHCS (1), these will hold the pre-
load cam in place.
7. Replace the sheet metal, reset the E-stop and clear the alarms.
