4.1 Safety Precautions
c WARNING: Read this Installation, Operation and Maintenance Manual completely before attempting to install,
operate, or troubleshoot the Flowserve Limitorque gearbox.
c WARNING: Potential HIGH-PRESSURE vessel — be aware of high-pressure hazards associated with the attached
valve or other actuated device when installing or performing maintenance on the gearbox. Do not remove the
gearbox mounting bolts from the valve or actuated device unless the valve or device stem is secured or there is no
pressure in the line.
c WARNING: For maintenance and/or disassembly of the gearbox while installed on the valve, ensure that the
gearbox is not under thrust or torque load. If the valve must be left in service, the valve stem must be locked in
such a way as to prevent any movement of the valve stem.
c WARNING: Do not manually operate the gearbox with devices other than the installed handwheel. Using force
beyond the ratings of the gearbox and/or using additive force devices such as cheater bars, wheel wrenches, pipe
wrenches, or other devices on the gearbox handwheel may cause serious personal injury and/or damage to the
gearbox and valve.
c WARNING: Do not exceed any design limitations or make modifications to this equipment without first consulting
Flowserve Limitorque.
c WARNING: Use of the product must be suspended any time it fails to operate properly.
a CAUTION: If a motor actuator is driving the gearbox, do not operate the valve under motor operation without first
checking and setting the limit switch setting and checking for correct motor rotation.
a CAUTION: Do not use replacement parts that are not Flowserve Limitorque parts, as serious personal injury and/or
damage to the gearbox and valve may result.
