5. Connect the hydraulics.
Using the provided hydraulic hoses, make connections between the pressure and release ports on the
grip and the pressure and release ports on the load unit or the external hydraulic grip supply. See the your
load unit product manual or hydraulic grip control manual for their port locations.
6. Install the wedges.
See the appropriate procedure to install wedges into the grips.

Warning:
The grips and their components can be heavy, which can make handling them awkward.
Dropping a grip or one of its components can cause injury to personnel and damage to equipment.
Ensure that you take appropriate precautions while moving and positioning the grips and their
components.
Installation of Model 647.250 Grips varies depending on system configuration. Contact MTS for additional
information. However, there are some considerations that are common to all installations:
• You typically need swivel hoist rings screwed into the provided threaded holes to attach a lifting device.
• It is recommended to have an overhead lifting device or fork lift that can support the weight of the grip.
Important:
NO STANDARD EYEBOLTS should be used to lift the grip.
Install the Grips in an Environmental Chamber
About Installation of the Grips in an Environmental Chamber
The all-temperature grips are designed to be used over a wide range of temperatures. To achieve a given
temperature, an environmental chamber is needed. Environmental chambers are available with or without
U-plugs. A Uplug is a removable panel that allows the chamber to be installed after the grips are installed.
