1-1. General

This manual contains maintenance instructions
for Duff Norton translating machine screw actuators
of two ton to 75 ton capacity. It describes and details
procedures for installation, disassembly, cleaning,
inspection, and assembly of these actuators.

1-2. Applications

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 which
authorizes the specific actuator unit, as used in your
application, as suitable for moving people.

Section I
These actuators are intended for a clean, non-
corrosive environment with ambient temperatures
ranging from -20 to 200 ° F. If your environment is
dirty and/or contains abrasive particles it is impor-
tant to protect the screw with a boot. If your atmo-
sphere is corrosive it is important to specify a non-
corrosive material or finish. Duff-Norton can provide
stainless steel, nickel plated or epoxy coated actua-
tors. If your duty is high or your use severe, more
frequent lubrication should be employed. Duff-
Norton publishes a Mechanical Actuator Design
Guide, Catalog No. 2003, which you may find helpful
in the selection and application of mechanical
actuators. If you need additional help, please con-
tact Duff-Norton at (800) 477-5002.
