Re: [A/S] Power Jack info and maintenance

[Crcattell@xxxxxxx]

Thanks Arnie, I have done more research on this topic and manufacturer's 
directions for maintenance can be found at: http://www.barkermfg.com/  next, click 
on to Product Instructions. Apparently, Barker owns H & H. Here are the 
directions the manufacturer gives: Under Maintenance, 

Once a year, the power head should be removed and a liberal amount of grease 
(preferably a grease with high melting point) applied directly to the coupling 
on which the pin rests.  DO NOT POUR OIL into top of Super Power jackpost. 
This may damage brake and cause jack to lower unexpectedly.

Once a year, the housing cover should be removed and the gears inspected for 
proper lubrication.  Remove 4 screws and tap around edges of housing to free 
the cover--DO NOT insert screwdriver blade--this may damage mating surfaces.  
Before replacing cover, clean mating surfaces. If lubrication is needed, use a 
Lithium based gear grease.
They warn and give directions: if Powerhead is removed, Powerhead must be 
synchronized with the jackpost.  They also give directions on how to do that.
Sorry to take so much room, since I started this discussion I felt it was 
necessary to set the record straight.
