Remove the two remaining upper mounting bolts at the top of the assist assembly and lift
the assembly from the mast tube.
NOTE:
The assist assembly weighs approximately 70 lbs (32Kg). It is
recommended two people lift the assembly from the mast. A hoist or
some other mechanical method may also be used.

Once the assist assembly is removed, components may easily be disassembled and ser-
viced as needed. Do not disassemble the gas spring cylinders.
WARNING!
The gas spring cylinders are pressurized. Disassembly of
cylinder may result in injury or damage to the cylinder.

When service is complete, reinstall the assist assembly in the reverse order of the disas-
sembly procedure. Reattach the chain with the master link. Replace the lower mounting
bracket and bolts (do not tighten bolts yet). Tighten the tension bolt until the end of the
bolt is flush with the top of the threaded block of the mounting plate. Tighten the mounting
bolts.
