Grease the Steer Axle
Wheel Bearings, 2WD Models
Genie specifications require that this procedure be
performed every 2000 hours or 2 years, whichever
comes first.
Maintaining the steer axle wheel bearings is
essential for safe machine operation and service
life. Operating the machine with loose or worn
wheel bearings may cause an unsafe operating
condition and continued use may result in
component damage. Extremely wet or dirty
conditions or regular steam cleaning and pressure
washing of the machine may require that this
procedure be performed more often.

them.
