3.2 Cleaning the spline shaft
Although depending on the air supply conditions and operating time, dust or grime adheres to the air path of
the spline shaft and may cause component pickup or mounting errors. The inside of the spline shaft should be
cleaned once every 6 months.

shaft maintenance.
There are 6 bolts used to plug the cleaning

Prepare the cleaning tool (KV8-
M8860-00X).
1. Pour IPA (isopropyl alcohol) into the
container of the cleaning tool. (Never
pour other solvent into the container.)

the cleaning tool so it is positioned 110 to
150mm away from the nozzle tip.

spline shaft to be cleaned. (This prevents
IPA from flowing out downwards.)
