All the replacement parts kits are identical for the double and single action versions and for all aluminum 
actuators.  RADIUS also recommends a spring replacement kit for each model.  These spring must be 
replaced in complete sets.  In each kit of springs, both springs and pre-tensors are supplied.

STORAGE

 

 
When an actuator is not put in service immediately (or is used intermittently), it is recommended that the 
actuator is operated at least three times a month using compressed air or nitrogen.  When it is not possible 
to operate them with air or nitrogen, and they can be operated manually (see PRINCIPLES OF MANUAL 
OPERATION).  It is recommended that they are stored indoors when space is available.  Care must be 
taken to plug up the openings to prevent the entry of foreign material and humidity.  The actuators must not 
be stored in places where the atmosphere is detrimental to the elastic seals.
