Unpacking
Unpacking
Carefully remove the positioner from the shipping container and inspect the unit for any evidence of
shipping damage. Report any damage immediately to your local authorized distributor. Please save
the shipping container for damage inspection or future transportation.
Incorrect handling of the positioner may adversely affect the performance of the unit in its application.
Please observe the following guidelines for handling and mounting of your new positioner.
DO NOT allow the positioner to drop onto the mounting surface. Dropping the positioner can gener-
ate impact loads that may result in flat spots on bearing surfaces or misalignment of drive com-
ponents.
DO NOT drill holes into the positioner. Drilling holes into the positioner can generate particles and
machining forces that may effect the operation of the positioner. Parker will drill holes if neces-
sary; contact your local authorized distributor.
DO NOT subject the unit to impact loads such as hammering, riveting, etc. Impacts loads generated
by hammering or riveting may result in flat spots on bearing surfaces or misalignment of drive
components.
DO NOT lift the positioner by the cables. Lifting positioner by the cables may effect electrical con-
nections. The unit should be lifted by the base structure only.
DO NOT expose positioner to mist, spray or submersion in liquids.
DO NOT disassemble positioner. Unauthorized adjustments may alter the positioner’s specifications
and void the product warranty.
