grease evenly.
When moving the swivel frame, make sure no person or material is in the swivel area.

Grease at each 90° position of the pitch bearing.
Using the grease gun, apply 5 shots at every
position. See the "Recommended lubricants"

person or material is in the swivel area. Turn the
starter switch to the STOP position and remove the
