DUTY CYCLE CHART
1-1. General
This page provides instructions for operation and mainte-
nance of Duff-Norton® 3405 and 6405 Series electro-
mechanical actuators. To ensure efficient, long and satis-
factory use of this unit, read and understand the informa-
tion herein, and follow the instructions 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 which author-
izes the specific actuator unit, as used in your applica-
tion, as suitable for moving people.
1-3. Factory Preparation
Each actuator is carefully assembled and tested at the
factory to ensure that the electrical and mechanical com-
ponents will function properly and that the actuator will
lift its rated load. The motor current draw is checked to
make certain that it is within Duff-Norton standards.
Every effort has been made to deliver this unit to
you in its factory approved state. You should, however,
carefully inspect the actuator for damage that may have
occurred during transit.
1-4. Friction Disc Clutch
The friction disc clutch is set so that the actuator will lift
its rated load, or a lighter load if so specified, but will slip
should the actuator be run into a jamming position at the
end of its travel. Thus, under overloads, or jamming con-
ditions, the clutch will slip while the motor continues to
run. If necessary, the clutch can be set to slip at a lighter
load by connecting an ammeter in the line at the motor,
loading the actuator, and, while operating, loosening the
clutch hex nut slightly until ammeter reads the required
current draw. (See table below.) Clutch is not effective
at loads of 50 pounds or less.
1-5. Warranty and Warranty Repair
Subject to the conditions stated herein, Duff-Norton will
repair or replace, without charge, any parts proven to
Duff-Norton’s satisfaction to have been defective in
material and workmanship. Claims must be made within
one year after date of shipment. Duff-Norton will not
repair or replace any parts that become inoperative
because of improper maintenance, eccentric loading,
overloading, chemical or abrasive action, excessive heat,
or other abuse.
Equipment and accessories not of Duff-Norton’s
manufacture are warranted only to the extent that they
are warranted by the manufacturer, and only if the
claimed defect arose during normal use, applications and
service. Equipment which has been altered or modified
by anyone without Duff-Norton’s authorization is not war-
ranted by Duff-Norton. EXCEPT AS STATED HEREIN,
DUFF-NORTON MAKES NO OTHER WARRANTIES,
EXPRESS OR IMPLIED, INCLUDING WARRANTIES OR
MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.
If you have any questions concerning warranty
repair, please contact Duff-Norton.
Authorization for return must be received from
Duff-Norton before returning any equipment for inspec-
tion or warranty repair.
2-1. To install the actuator, simply support and secure it
# Total inches travel (up and down) per hour with equally timed intervals
between cycles.
