4.3.5 Connecting compressed air connection

See Figure 4
The compressed air connection on the MDR
lubricant reservoir comes standard with an
SKF plug connector for a 6 mm tube. The
compressed air line (provided by customer) is
connected as described below.
The SKF plug connector attached to the com-
pressed air connection of the lubricant reservoir
is designed for plastic tubing. A locking claw
on the collet secures the plastic tube in the
plug connector, which prevents the tube from
accidentally slipping out.
• Cut the plastic tube (1) straight using a
suitable tube cutter (see Chapter 12,
Accessories).
In the following installation of the plastic
tube, a noticeable resistance must be over-
come when passing through the first O-ring
(2), the locking claw (5) of the collet (4).
• Use one hand to manually insert the plastic
tube (1) fully into the collet (4) of the plug
connector until it clears the first O-ring (2)
and the locking claw (5) of the collet (4) and
reaches the mechanical stop (3).
To remove the plastic tube (1), press the collet
(4) inward into the plug connector. To do this,
also press the plastic tube (1) inward into the
plug connector fitting, which releases the collet
(4) from the plastic tube (1). The plastic tube
(1) can now be pulled out of the collet (4) of
the plug connector.
Before reassembling, shorten the end of the
plastic tube by at least 7 mm to ensure that
the locking claw of the collet functions
properly.
