9.7.1 D2000 Swivel Joints
Each D2000 swivel joint is provided with a bolt (Item #6) in the ball race plug
(Item #5). To visually check the lubrication, remove bolt (item #6) only. Do not
remove the ball race plug (item #5) as balls may fall out.
The D2000 swivel joints are provided with grease sufficient for 5 years of service
provided that the seals are intact and pressure and temperature limits are not
exceeded. For heated or chemical applications the swivels are warranted for 1
year of service. In these applications the grease should be checked and re-
greased annually.
D2000 grease kits include a grease nipple and standard tube of grease specific
to the application. Use the grease nipple at the swivel joint casing to lubricate
the swivel joint. Rotate the swivel joint while greasing to distribute the lubricant.
9.8 Spring Cylinder Maintenance
The spring cylinder balances the A-length of the loading arm and enables smooth
movement within the operating range of motion. The loading arm is neutrally
balanced at the factory to maintain its position when at rest.
Grease the pivot joints and the cylinder rod every six months. Check the spring
cylinder for damage.
Make sure that the warning placard is attached to the spring cylinder. Replace it
immediately when damaged or missing.
Warning
The spring cylinder contains stored
energy. When adjusting use extreme
care or severe injury could result
Only authorized persons shall maintain
the spring cylinder who have been
trained by EMCO WHEATON
