Remove the VK cover using one of the re-
commended 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.
