Safety instructions and measures
1 Safety instructions and measures
Intended use
The SAMSON Type3273 Hand-operated Handwheel is mounted on a valve and is intended
for the following activities in combination with a pneumatic actuator (e.g. SAMSON
Type3271 or Type3277 Actuator):
− To manually move the valve to the closed or open position for maintenance or repair
work (e.g. while exchanging the actuator)
− To manually move the valve upon air supply failure
− To hold the valve in the fail-safe position while performing maintenance and repair work
on the pneumatic actuator
− Special version: to operate a mounted valve without pneumatic actuator
The side-mounted handwheel in combination with a pneumatic actuator is not suitable to
perform control tasks. The side-mounted handwheel is designed to operate under exactly de-
ned conditions (e.g. thrust, travel, actuator area). Therefore, operators must ensure that the
side-mounted handwheel is only used in operating conditions that meet the specications
used for sizing at the ordering stage. In case operators intend to use the handwheel in other
applications or conditions than specied, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The handwheel is not suitable for the following applications:
− Limiting the valve travel
− Controlling the ow rate through the valve (except for the special version without pneu-
matic actuator)
− Use outside the limits dened during sizing and by the technical data
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described

Safety instructions and measures
Qualications of operating personnel
The handwheel must be mounted, started up, serviced and repaired by fully trained and
qualied personnel only; the accepted industry codes and practices must be observed. Ac-
cording to these mounting and operating instructions, trained personnel refers to individuals
who are able to judge the work they are assigned to and recognize possible hazards due to
their specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.
Personal protective equipment
We recommend wearing the following protective equipment:
− Safety gloves due to the moving parts (actuator stem, threaded rod, plug stem, hand-
wheel)
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications of the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety devices
The side-mounted handwheel is locked by a locking bolt, which locks the gear, to prevent
accidental adjustment of the valve travel (see Fig. 11 and section7.1).
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the handwheel by the signal pressure or moving
parts by taking appropriate precautions. Plant operators and operating personnel must ob-
serve all hazard statements, warning and caution notes in these mounting and operating in-
structions.
Responsibilities of the operator
Operators are responsible for proper use and compliance with the safety regulations. Opera-
tors are obliged to provide these mounting and operating instructions as well as the refer-
enced documents to the operating personnel and to instruct them in proper operation. Fur-
thermore, operators must ensure that operating personnel or third parties are not exposed to
any danger.

Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the specied hazard statements, warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicable
health, safety and accident prevention regulations and comply with them.
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
− Mounting and operating instructions for the mounted actuator, e.g. for Type3271 or
Type3277 Pneumatic Actuator:

Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER
!
The handwheel poses no hazard with possible severe personal injury.
ÎObserve hazard statements in the associated valve and actuator documentation.
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The handwheel contains moving parts (actuator stem, threaded rod, plug stem, hand-
wheel), which can injure hands or ngers if inserted into it.
ÎDo not insert hands or nger into the yoke while the valve is in operation.
ÎWhile working on the handwheel, disconnect and lock the pneumatic air supply as
well as the control signal.
ÎUse the locking bolt to lock the handwheel.
Risk of personal injury due to incorrect removal of the anti-rotation xture with
clamps under tension.
Once the actuator has been mounted on the valve and the assembly is ready for use,
the clamps of the anti-rotation xture on the plug stem are under tension.
ÎFollow the instructions in this document during mounting or removal.
ÎFirst remove the actuator from the valve or ensure it cannot transmit any forces to
the actuator stem before removing the anti-rotation xture on the plug stem.
Exposure to hazardous substances poses a serious risk to health.
Certain lubricants and cleaning agents are classied as hazardous substances. These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.
ÎMake sure that an MSDS is available for any hazardous substance used. If neces-
sary, contact the manufacturer to obtain an MSDS.
ÎInform yourself about the hazardous substances and their correct handling.

Safety instructions and measures
1.3 Notes on possible property damage
NOTICE
!
Risk of handwheel damage due to the use of unsuitable tools.
ÎTo turn the handwheel, do not use any additional tools, such as a lever or wrench.
Risk of handwheel damage due to the use of excessive force.
ÎDo not turn the handwheel any further when it has reached its end position by ex-
erting force.
Risk of damage to control valve components due to excessively high or low tighten-
ing torques.
Observe the specied torques when tightening control valve components. Excessive
tightening torques lead to parts wearing out more quickly. Parts that are not tightened
far enough may loosen.
ÎObserve the specied tightening torques (uAB0100).
