Hydromechanical System Precautions
Hydraulic systems have the capacity for rapid and forceful movement. Systems contain equipment that
can be hazardous to persons and damaging to equipment, if improperly used.
Warning:
Do not perform calibration, maintenance, or repair procedures with the hydraulic system
operating.
This can cause injury to persons or damage to equipment or both (due to unexpected actuator
movement).
Ensure that you read the following precautions.
Follow these precautions:
• Do not permit untrained people to operate, or service the system.
• Ensure that the Hydraulic Power Unit (HPU) is turned off before you service or go near hydraulic
equipment. When servicing multi-channel HSMs, MTS recommends that you install a shut-off valve
and lock-out tag on each HSM to ensure that HPU pressure is not applied to the HSM being serviced.
• Remove from the test area all devices which can be damaged by full force, rate, distance, or rotational
movement of the actuator.
• Hydraulic system fluids can be irritating to skin and eyes and are poisonous if taken internally.
• Hydraulic systems operate at high pressures and the spray from even a small leak can cause cutting
or piercing injuries. If possible, test new equipment at low pressure and only when no one is near the
system.
• Use only specified parts for replacement. Replacement parts found in hardware stores are not suitable
for HSM maintenance and may rupture explosively when pressurized. Contact your MTS service
representative or MTS Systems Corporation for part numbers.
Model 293.32 HSM Main Filter Cleaning
The main filter is a metal screen, mesh-type filter which should be removed and cleaned (or replaced if
damaged) at six-month intervals.
The replacement filter kit is MTS part number 052-957-901. It includes a 25µ (absolute) filter and a seal
for the filter bowl.
