Hazard - Do not place a testing system off-line from computer control without first
ensuring that no actuator or crosshead movement will occur upon transfer to
manual control.
The actuator or crosshead will immediately respond to manual control settings when the
system is placed off-line from computer control. Before transferring to manual control,
make sure that the control settings are such that unexpected actuator or crosshead
movement cannot occur.
Rotating Machinery Hazard - Disconnect power supplies before removing the
covers to rotating machinery.
Disconnect equipment from all power supplies before removing any cover which gives
access to rotating machinery. Do not reconnect any power supply while the covers are
removed unless you are specifically instructed to do so in the manual. If the equipment
needs to be operated to perform maintenance tasks with the covers removed, ensure that
all loose clothing, long hair, etc. is tied back. Refit covers as soon as possible.
Hazard - Shut down the hydraulic power supply and discharge hydraulic pressure
before disconnection of any hydraulic fluid coupling.
Do not disconnect any hydraulic coupling without first shutting down the hydraulic
power supply and discharging stored pressure to zero. Tie down or otherwise secure all
pressurized hoses to prevent movement during system operation and to prevent the hose
from whipping about in the event of a rupture.
Hazard - Shut off the supply of compressed gas and discharge residual gas
pressure before you disconnect any compressed gas coupling.
Do not release gas connections without first disconnecting the gas supply and
discharging any residual pressure to zero.
Hazard - Ensure components of the load string are correctly pre-loaded to
minimize the risk of fatigue failure.
Dynamic systems, especially where load reversals through zero are occurring, are at risk
of fatigue cracks developing if components of the load string are not correctly pre-loaded
to one another. Apply the specified torque to all load string fasteners and the correct
setting to wedge washers or spiral washers. Visually inspect highly stressed components
such as grips and threaded adapters prior to every fatigue test for signs of wear or fatigue
damage.
