10.7. EXTENDED PERIODS OF STANDSTILL
When gear units are at standstill for an extended period, the protective oil
film containing anti corrosion additives gradually disappears and the unpro-
tected internal parts become subject to corrosion. Adverse ambient condi-
tions such as humid, marine, tropical and chemically aggressive environ-
ments will accelerate the process.
A periodic visual inspection through the inspection cover is required.
Corrosion of the internals can be avoided by letting run the gear unit for a
few minutes every two weeks (depending on the ambient conditions) thus
allowing the formation of a new oil film.
Install a special breather (marked with the label shown below) to prevent
moisture from entering the gear unit.
If it is not possible to run the unit regularly and the risk for corrosion is immi-
nent, during extended periods of standstill the unit must be protected as
follows :
- an oil soluble concentrate including corrosion inhibitors which are active
both in the liquid and in the vapour phase has to be added. A 2% volume
concentration is considered to be normal. Consult your oil supplier about
lifetime, compatibility with the actual oil and about volume concentration.
- seal all gear unit openings (dipstick, breather etc.) hermetically .
Before new starting-up: read chapters 9 and 10, release her-
!
metical seals.
10.8. SERVICE AFTER SALES
For technical assistance or additional information, the HANSEN sales centres
are at your disposal. When you contact them, please specify the complete
type code and the manufacturing number mentioned on the gear unit's name-
plate.
10.9. REPAIRS
Any repair should only be carried out by qualified personnel.
Only original HANSEN spares should be used.
No products or substances may be used in the gear unit that could bring for-
eign ingredients (particularly solid or friction reducing additives amongst oth-
!
er things) in the oil.
