Action
Note
1. Check the seal to ensure that:
•
the seal is of the correct type (provided with cutting
edge).
•
there is no damage to the sealing edge (feel with a
fingernail).
2. Inspect the sealing surface before mounting. If scratches or
damage are found, the seal must be replaced since it may
result in future leakage.
3. Lubricate the seal with grease just before fitting. (Not too
early - there is a risk of dirt and foreign particles adhering to
the seal.)
Fill 2/3 of the space between the dust tongue and sealing lip
with grease. The rubber coated external diameter must also
be greased, unless otherwise specified.
Art. no. is specified in

leakage.
