1-1. General
This manual provides instructions for the installation,
operation and maintenance of the Duff-Norton 6415
Series DC actuator. It includes proper procedures for
the disassembly, cleaning, inspection, rebuilding and
assembly of the actuator. To ensure efficient, long,
satisfactory use of this unit, these instructions should be
followed closely.
1-2. Industrial Use Only
The actuators described and illustrated in this manual
are intended for industrial use only and should not be
used to lift, support or otherwise transport people, unless
you have a written statement from Duff-Norton Company
which authorizes this actuator unit, as used in your
application, as suitable for moving people.
1-3. Factory Preparation
Each actuator is carefully assembled and tested at the
factory to ensure that the motor and the mechanical
components will function properly and that the actuator
will lift its rated load.
The brake is preset at the factory and no further
adjustment is required. With proper maintenance, this
brake prevents the actuator from self-lowering.
The actuator is pre-lubricated at the factory and thus
requires minimum maintenance.
Limit switches are checked at the factory for proper
functioning.
External wires are provided for customer hookup. Wires
are color coded as to direction of travel of the actuator
(see wiring diagram, Figure 6.2).
