Read all manuals
Study the contents of this manual and the other manuals provided with your system before attempting to
perform any system function for the first time. Procedures that seem relatively simple or intuitively obvious
may require a complete understanding of system operation to avoid unsafe or dangerous situations.
Locate and read hazard placards/labels
Find, read, and follow the hazard placard instructions located on the equipment. These placards are placed
strategically on the equipment to call attention to areas such as known crush points, electrical voltage,
and high pressure hazards.
Specimen Temperature Changes
During environmental testing, the specimen temperature can become hot enough to cause burns. Wear
personal protection equipment (gloves) when handling specimens.
Know facility safe procedures
Most facilities have internal procedures and rules regarding safe practices within the facility. Be aware of
these safe practices and incorporate them into your daily operation of the system.
Know controls
Before you operate the system for the first time, make a trial run through the operating procedures with
the power off. Locate all hardware and software controls and know what their functions are and what
adjustments they require. If any control function or operating adjustment is not clear, review the applicable
information until you understand it thoroughly.
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.
