AIR EJECT MAINTENANCE
The Air Eject is a precision device designed and manufactured for many years of reliable
service. Periodic servicing, cleaning and lubricating are important.
It is suggested that the cylinder assembly be inspected regularly and cleaned and
lubricated at a minimum once every six months.
In applications where contamination by water and road dirt are excessive, more frequent
servicing may be required.
Lubrication should be only with non-petroleum based lubricants such as Dow Corning DC4 Silicone grease, Silicone or Teflon spray.
