IMPORTANT:

  Do not oil or grease the 

pivot points which have special nylon 
bearings.  Viscous lu bri cants will attract 
dust and dirt that will short en the life of the 
self-lu bri cat ing bearings.  If you feel they 
must be lu bri cat ed, use only a dry, pow-
 dered graphite type lu bri cant spar ing ly.
