9.4. Coupling

It is recommended to lubricate all coupling parts regu-
larly (approx. once a week) with waterproof grease
to prevent leaks and damage of packings. If the unit
is equipped with a spray gun the piston of the gun
should also be lubricated.
In leaking quick couplings the packings should be
replaced.
