Hytork XL actuators are only intended for use in large-scale xed installations excluded
from the scope of Directive 2011/65/EU on the restriction of the use of certain hazardous
substances in electrical and electronic equipment (RoHS 2).
Installation, adjustment, putting into service, use, assembly, disassembly, and maintenance
of the actuator is strictly reserved to qualied personnel.
Before installation, operation and maintenance, read the relevant sections of:

!
CAUTION
Always disconnect the air and electrical supplies before carrying out any form of
maintenance on an actuator.
When removing any ball valve or plug valve assemblies from a pipe system,
isolate the piping system on which the actuator is installed and relieve any media
pressure that may be trapped in the valve cavities before removing the actuator
for maintenance.
Always contain the spring tension with Hytork retractor rods as explained in
Section 9.1 (Disassembly Procedure). Follow instructions for using the retractor
rod carefully. Only Hytork manufactured or approved retractor rods are to be
used for spring removal. As with any threaded tool that is frequently used retractor
rods should be checked to ensure that the threads are not worn or damaged in any
way and greased regularly. Any damaged or worn rods must not be used and must
be destroyed.
Never attempt to “BLOW OUT” the pistons or the end caps from the actuator body
by using air pressure.
Never turn the stop screws completely out when the actuator is under pressure.
