Turn HIGH POWER (ARM POWER) off.
2.
Remove the quill cover and move the quill to its fully-raised
position.
3.
Apply a thin coating of grease to the ballscrew threads and move the
ballscrew up and down several times to ensure an even spread of

Lubrication of Joint 4
1.
Turn HIGH POWER (ARM POWER) off.
2.
Move the quill to its fully-raised position.
3.
Using a 5/16-inch Allen wrench, remove the grease fitting access
plug from the side of the Joint 4 housing. See Figure 4-1.
4.
While looking through the access plug hole, rotate the quill until the
zerk fitting is accessible.
5.
Insert the tip of a grease gun and apply grease until excess grease
squeezes out from the quill seal.
6.
Remove the grease gun.
7.
Reposition the quill to the bottom of its travel and wipe excess grease
from the quill.
8.
Replace the access plug.
The quill MUST be in the fully-raised position before
lubricating.
Improper quill positioning could result in
excessive lubricant getting on the Joint 4 brake, which
could cause its failure.
