Safety
24 Series 505G2 SilentFlo™ Hydraulic Power Unit
Have first aid available
Accidents can happen even when you are careful. Arrange your operator schedules so that a properly
trained person is always close by to render first aid. In addition, ensure that local emergency contact
information is posted clearly and in sight of the system operator.
Know potential crush and pinch points
Be aware of potential crush and pinch points on your system and keep personnel and equipment clear
of these areas.
Remember, when hydraulic power is interrupted on a servohydraulic system, it is likely that stored
accumulator pressure will persist for some time within the system. In addition, it is likely that as stored
energy dissipates, gravity will cause portions of the system to move.
Be aware of component movement with hydraulics off
The actuator rod can also drift down when hydraulics are turned off hitting anything in its path. This
uncommanded movement is because of oil movement between the pressure/return ports and oil blow
by across the piston hub. Be aware that this can happen and clear the area around the actuator rod
when hydraulics are turned off.
Know electrical hazards
When the system electrical power is turned on, minimize the potential for electrical shock hazards.
Wear clothing and use tools that are properly insulated for electrical work. Avoid contact with exposed
wiring or switch contacts.
Whenever possible, turn off electrical power when you work on or in proximity to any electrical system
component. Observe the same precautions as those given for any other high-voltage machinery.
Make sure that all electrical components are adequately grounded. Grounds must remain connected
and undisturbed at all times.
Keep bystanders safely away
Keep bystanders at a safe distance from all equipment. Never allow bystanders to touch specimens or
equipment while the test is running.
Wear proper clothing
Do not wear neckties, shop aprons, loose clothing or jewelry, or long hair that could get caught in
equipment and result in an injury. Remove loose clothing or jewelry and restrain long hair.
Remove flammable fluids
Remove flammable fluids from their containers or from components before you install the container or
component. If desired, you can replace the flammable fluid with a non-flammable fluid to maintain the
proper proportion of weight and balance.
