WARNING
The upper part of the enclosure can fall down
The bracket stops the upper part of the enclosure from falling. If the bracket is removed
when the machine is in a vertical position, or if the machine is placed in a vertical position
without the upper part of the enclosure secured by the bracket, the upper part of the
enclosure can fall. Death, serious injury, or material damage can result.
Only remove the bracket when the machine is in a horizontal position.
1. In machines of vertical construction type, remove the bracket for the upper part of the
enclosure when the machine is horizontal.
2. Do not remove the fixing screws on the machine enclosure until then.
3. When assembling the machine, replace the bracket before the machine is placed in a
vertical position. Lock the bolts.
● Only use the lifting lugs welded onto the upper part of the housing to lift it. The weight of
the upper part of the housing can be found in the "Technical specifications" section.
● Before lifting off the upper part of the housing, loosen the equipotential bonding conductor
and the fixing bolts on the stator housing.
Assembly
● Fit the air intake cowl before the upper part of the enclosure. Only fit the upper part of the
enclosure and the air intake cowl when the machine is in a horizontal position.
● Do not change the arrangement of the flexible components underneath the bolt heads.
● Apply a soluble adhesive to the set screws e.g. Loctite 243. Tighten the set screws so
that the joins with the stator housing are tight all the way round.
● Only use the hoisting lugs welded onto the upper part of the enclosure to lift it. The weight
of the upper part of the housing can be found in the "Technical specifications" section.
● After putting it down, secure the equipotential bonding conductors and the fixing screws
on the stator housing.
● When securing, ensure that the tensioning straps and the spherical disks are arranged
correctly. Tightening torque for the fixing screws is 10Nm.
