3HAC063331-001 Revision: B
Action
Fit the lifting accessory to the shackle and
raise to unload the weight.
Action
Remove the both VK covers using one of
the recommended methods:
• Drive a screwdriver (or similar)
through the VK cover, as close as
possible to the center of the VK
cover, and bend out the cover. If not
making a hole in the center of the
VK cover, there is a risk of damaging
the bearing inside. The damaged VK
cover must be replaced with a new.
• Remove the protection screw from
the vent hole and use air pressure
through the hole to blow out the
cover. The cover can be reused if
not damaged.
Wipe off any residual grease inside the re-
cess.
