INTRODUCTION

The following instructions are designed to assist in
unpacking, installing and performing maintenance
as required on Optimux Spring Cylinder Rotary
Actuators. Product users and maintenance
personnel should thoroughly review this bulletin
prior to installing, operating or performing any
maintenance on the actuator. 

This publication does not contain information on
Optimux positioners. Refer to the appropriate
maintenance bulletin for installing, calibrating,
maintaining, troubleshooting and operating
Optimux positioners.

Unpacking

1. While unpacking the actuator, check the

packing list against the materials received.

2. When lifting the actuator from the shipping

container, position lifting straps and hoist to
avoid damage to tubing and mounted
accessories.

WARNING

:

When lifting an actuator

with lifting straps, be aware the
center of gravity may be above the
lifting point. Therefore, support
must be given to prevent the
actuator from rotating. Relieve
spring compression by removing
adjusting screw.

3. Contact your shipper immediately in the case

of any shipping damage.

4. Contact your Optimux representative with any

problems.
