2.2.1 Handling the FC Motor
Handling and lifting of VLT DriveMotors (FC motors) must
only be undertaken by qualified personnel. Full product
documentation and operating instructions must be
available together with tools and equipment necessary for
safe working practice. Eyebolts and/or lifting trunnions
supplied with the FC motor are designed to support only
the weight of the FC motor, not the weight of the FC
motor and any aucillary equipment attached to it. Be
absolutely sure that cranes, jacks, slings and lifting beams
are capable of carrying the weight of equipment to be
lifted. Where an eyebolt is provided with the motor, this
should be screwed down until its shoulder is firmly against
the face of the stator frame to be lifted.

2.2.2 Bearings
The standard solution is fixed bearing in the drive side of
the motor (shaft output side).
To avoid static indention, the storage area should be
vibration free. Where exposure to some vibration is
unavoidable, the shaft should be locked. Bearings may be
fitted with a shaft locking device which should be kept in
place during storage. Shafts should be rotated by hand,
one quarter of a revolution, at weekly intervals. Bearings
are despatched from the works fully charged with lithium
based grease.
