Safety
26 Series 505G2 SilentFlo™ Hydraulic Power Unit
Use appropriately sized fuses
Whenever you replace fuses for the system or supply, ensure that you use a fuse that is appropriately
sized and correctly installed. Undersized or oversized fuses can result in cables that overheat and
fuses that explode. Either instance creates a fire hazard.
Provide adequate lighting
Ensure adequate lighting to minimize the chance of operation errors, equipment damage, and
personal injury. You need to see what you are doing.
Provide means to access out-of-reach components
Make sure you can access system components that might be out of reach while standing on the floor.
For example, ladders or scaffolding might be required to reach load cell connectors on tall load units.
Wear appropriate personal protection
Wear eye protection when you work with high-pressure hydraulic fluid, breakable specimens, or when
anything characteristic to the specimen could break apart.
Wear ear protection when you work near electric motors, pumps, or other devices that generate high
noise levels. Some systems can create sound pressure levels that exceed 70 dbA during operation.
Wear appropriate personal protection equipment (gloves, boots, suits, respirators) whenever you work
with fluids, chemicals, or powders that can irritate or harm the skin, respiratory system, or eyes.
Handle chemicals safely
Whenever you use or handle chemicals (for example, cleaning fluids, hydraulic fluid, batteries,
contaminated parts, electrical fluids, and maintenance waste), refer to the appropriate MSDS
documentation for that material and determine the appropriate measures and equipment required to
handle and use the chemical safely. Ensure that the chemical is disposed of appropriately.
Know system interlocks
Interlock devices should always be used and properly adjusted. Interlock devices are designed to
minimize the chance of accidental damage to the test specimen or the equipment. Test all interlock
devices for proper operation immediately before a test. Do not disable or bypass any interlock devices
as doing so could allow hydraulic pressure to be applied regardless of the true interlock condition. The
Reset/Override button is a software function that can be used to temporarily override an interlock
while attempting to gain control of the system.
Know system limits
Never rely on system limits such as mechanical limits or software limits to protect you or any personnel.
System limits are designed to minimize the chance of accidental damage to test specimens or to
equipment. Test all limits for proper operation immediately before a test. Always use these limits and
adjust them properly.
Do not disturb sensors
Do not bump, wiggle, adjust, disconnect, or otherwise disturb a sensor (such as an accelerometer or
extensometer) or its connecting cable when hydraulic pressure is applied.
