Check bolt ratings and torques

To ensure a reliable product, fasteners (such as bolts and tie rods) used in MTS-manufactured systems are

torqued to specific requirements. If a fastener is loosened or the configuration of a component within the

system is modified, refer to information in this product manual to determine the correct fastener, fastener

rating, and torque. Over torquing or under torquing a fastener can create a hazardous situation due to the

high forces and pressures present in MTS test systems.

On rare occasions, a fastener can fail even when it is correctly installed. Failure usually occurs during torquing,

but it can occur several days later. Failure of a fastener can result in a high velocity projectile. Therefore, it

is a good practice to avoid stationing personnel in line with or below assemblies that contain large or long

fasteners.

Lift Equipment Safely

Grips that are too heavy to be lifted by hand are to be lifted with double swivel eyebolts supplied by MTS,

part number 100-263-718.

Warning:

Large capacity grips are heavy, and must be lifted using hoist rings.

Such grips should be lifted with hoist rings supplied by MTS Systems Corporation.

If hoist rings other than those provided by MTS are used, the customer must ensure that the

other grips are suitable for the purpose.

Practice good housekeeping

Keep the floors in the work area clean. Hydraulic fluid that is spilled on any type of floor can result in a

dangerous, slippery surface. Do not leave tools, fixtures, or other items not specific to the test, lying about

on the floor, system, or decking.

Do not exceed the Maximum Supply Pressure

For hydraulic grips and fixtures. make sure that the hydraulic supply pressure is limited to the maximum

pressure defined by the grip or fixture identification (ID) tag.

Do not disable safety devices

Your system may have active or passive safety devices installed to prevent system operation if the device

indicates an unsafe condition. Do not disable such devices as it may result in unexpected system motion.

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.
