To be strictly honest, unless I've done it wrong, mine has been a P.I.T.A.
Disconnect the power supply and take note from which plug you remove the cable.
Remove the solution tube from both jets.
Undo the lock-nuts from both long bolts that hold the spraying system onto the frame.
MAKE SURE YOU KEEP ALL WASHERS/SPACERS, ETC; IN CORRECT ORDER & DIRECTION FOR WHEN YOU ARE GOING TO REPLACE SAME.
There is a schematic diagram in the manual of correct placement of all items.
You may still want to remove the jets from the top of the cowling/base plate.
I think that's all.
I downloaded the manual from:

Orbot SprayBorg Bottle Cartridge Anti-Vibration System
The Orbot SprayBorg Bottle Cartridge Anti-Vibration System was designed to eliminate vibration in the handle.
If you need to take off or assemble the system, please mount the fasteners, dampers, springs, and nylon washers in the exact order as shown in the diagram below (see figure 24).
Failure to fasten the system in the order shown in the diagram will lead to possible operator discomfort.
When mounting the system to the Orbot, fasten tightly; not too loose nor too tight.
Do not tighten so that the spring coils are closed. Allow approximately 1/16” (.060”) between each coil.
Hope this helps.
