The gear unit must not be put into operation unless:
■ no damage caused, for example, by storage or transport, is apparent.
■ in particular, the shaft seals, cover caps, and guard hoods are not damaged.
■ no leaks or loss of oil are visible.
■ no corrosion or other indication of improper storage or storage under damp conditions is present.
■ all of the packaging materials were removed.
■ oil drain plugs and vent plugs must be fully accessible!
As a general rule, drive shafts and ange surfaces must have all corrosion protection products and dirt cleaned from them,
standard commercial solvents can be used.
The gear unit may only be operated in the specied mounting position, which may be found on the nameplate. The moun-
ting position must not be changed during operation.
Every Urelast spring must be mounted with a pre-stressing of 2 mm (F02, F03) or 3 mm (F04, F05, F06, F07).
If the gear unit will be painted or partially repainted, make certain that the vent plug and the shaft seals are carefully mas-
ked. Remove the masking tape after the painting work is completed.
In order to prevent excessive heating of the gear unit, the following must be observed:
■ Sufcient clearance must be provided around the gear unit.
■ The cooling air for gear unit motors must be able to ow unhindered around the gear unit.
■ The gear unit must not be completely boxed in with a housing.
■ The gear units must not be exposed to hot exhaust air from other units.
No heat must be transferred into the gear unit.
It must be ensured that there are no foreign bodies, dirt or moisture in the terminal box. Open entries are to be sealed
with an O ring or a suitable at gasket so that dust and water cannot enter, whereas the terminal box itself is to be sealed
against dust and water with the original seal.
It must be ensured that the terminal box, terminal board and cable connections etc. inside the terminal box are not dam-
aged!
ATTENTION!
The sealing lips on the shaft seals must not be allowed to come in contact with the solvent!
Material can be damaged!
WARNING!
The terminal box must be sealed so that dust and water cannot enter!
