SAFETY NOTICE SN708

 

DATE: 3/3/2022

REVISED:

 

TO: Owners, Users, Dealers, and Installers

MODELS AFFECTED: OM, TCX, & Optima HRX

 

SUBJECT: Dual Platform Emergency STOP

 

Issue:

Terex model OM, TCX, and Optima HRX dual platform aerial devices, produced from June 2016 through November 2021, may have Emergency STOP controls that fail to stop all functions at the upper controls.  The Emergency STOP controls will stop the function of the controls at its respective control station but may not stop the function of the controls in the other control station.  Failure to correct the operation of the Emergency STOP controls may result in the inability to stop inadvertent machine movement.

 

Action:

What the Owner Must Do:

The owner must inspect their equipment and correct if required.

  1. Immediately inform all users, operators, and supervisors that the operation of the Emergency STOP must be inspected from both platforms within 10 days of receiving this bulletin. This bulletin only applies to OM, TCX, and Optima HRX models with dual platforms.
  2. Inspect the operation of the Emergency STOP control from both platforms. If the Emergency STOP is activated in either platform, the boom controls should not operate from either platform.
  3. If activation of either Emergency STOP control allows boom operation from either platform, this bulletin applies.
    1. If your machine is equipped with Engine Stop/Start only at one platform control station, contact Terex using one of the contact methods listed in the “What Terex will Do” section within 10 days of receiving this bulletin to arrange for installation of Field Service Kit Z1648. See the continued use section for further instructions until Field Service Kit Z1648 is installed.
    2. If your machine is equipped with Engine Stop/Start at both platform control stations, refer to the Field Service Kit Z1649 instructional drawing to install Emergency STOP placards at the upper control stations and for Emergency STOP validation. After completing the placard installation and Emergency STOP validation, complete the enclosed Completion Form and return it to Terex.  Once this is complete, the unit can be used following all operator, maintenance, and inspection requirements as specified in the manuals.
  4. If activation of either Emergency STOP control prevents boom operation from both platforms, this bulletin does not apply. The unit can be used following all operator, maintenance, and inspection requirements as specified in the manuals.

 

Continued Use:

  1. Inform the users of the content of this bulletin and remind them of the daily pre-shift inspection requirements.
  1. If the Emergency STOP control does not stop all boom functions, utilize one of the following procedures to stop all boom functions:
    1. Activate the Emergency STOP control in both platforms or press the Engine Stop/Start plunger at either platform control (if equipped).
    2. At the lower control station, move the selector to Lower or Emergency STOP.
    3. At the rear of the chassis, press the Emergency STOP button or move the selector to the outrigger position; if safe to do so, if in contact with the ground.
  2. Always follow inspection and maintenance requirements as specified in the manuals.

 

What Terex will Do:

Terex will provide Field Service Kit Z1648 or Z1649 for installation on your unit at no cost to the owner.

Field Service Kit Z1648 will add a Stop/Start plunger to the passenger’s control station and will add

Emergency STOP placards to both upper control stations.  Field Service Kit Z1649 will add Emergency STOP placards to both upper control stations and is intended for machines that are already equipped with Engine Stop/Start plungers at both upper control stations.

Chronology :

The issue was first identified by a Terex team member on April 21, 2020 when testing an Optima-HRX aerial device. On May 19, 2020 the decision was made to research how the Emergency Stop functioned on other models of aerial devices with dual baskets. On September 1, 2020 the research into how the E-Stop functioned on other models was completed. On September 22, 2020 the research into a modified E-Stop for the Optima model began. On April 20, 2021 the research into a modified E-Stop for the Optima was completed. On June 1, 2021 research began to determine if the modified system could be retrofitted to older field units. Production changed to the modified E-Stop on December 1, 2021. On November 9, 2021 it was determined that an alternative method of modifying field units would be to use the Engine Stop/Start to stop all oil flow for the Emergency Stop. The Engine Stop/Start is already indicated in the Operator’s Manual as an acceptable method of stopping machine function. Research and documentation of field retrofit kits for the Engine Stop/Start completed February 2, 2022. Even though there are no reports of issues, a decision to recall was made on March 3, 2022.
