SAFETY NOTICE SN681A

 

DATE: 4/6/2020

REVISED:      5/27/2020

 

TO: Owners, Users, Dealers, and Installers

MODELS AFFECTED: TM Aerial Devices

 

SUBJECT: Leveling Sensor Installation

 

Issue:

On Terex TM aerial devices, manufactured from February 2011 through April 2020, the basket level limit sensors at the boom tip may have been assembled in the incorrect orientation.  The limit sensors prevent the platform from going more than 15 degrees from level if the electrical system malfunctions or there is damage to components.  The incorrect mounting of the level sensors may cause an out of level basket to continue moving more than 15 degrees out of level.  If the leveling system malfunctions it may cause the occupants to fall from the platform.

 

Action:

What the Owner Must Do:

The owner must inspect their equipment and correct if required within 10 days of receiving this bulletin.

  1. Inform all users, operators, and supervisors that the basket level sensors must be inspected within 10 days on TM aerial devices and follow the continued use section of this bulletin until the unit is corrected. This bulletin applies to TM Aerial devices with the hydraulic generator at the boom tip and applies to machines with an end mount platform or dual side mount platforms.
  2. Inspect the unit to determine if your unit has the incorrectly installed level sensors.

  1. If your unit has the light colored potting visible on the top sensor, or the sensor labeled A on the bottom; this bulletin applies. Correct following the instructions in Field Service Kit Z1562. Take a picture before correcting the issue and another picture after correcting the issue.  Send both pictures with the completion form including the serial number and date of correction to [email protected].
  2. If your unit has the light colored potting visible only on the bottom sensor with the wires coming out of the sensors above the mounting screw and with sensor labeled A on top this bulletin does not apply and use can continue without restriction.

 

Continued Use:

  1. Inform the users of the content of this bulletin and remind them of the daily pre-shift inspection requirements.
  2. If the leveling system malfunctions and the platform gets more than 15 degrees out of level utilize one of the following procedures to stop the leveling system:
    1. Release the enable lever and use the manual level adjustment control to correct the level of the platform.
    2. From the lower controls shut off the upper controls and use the lower controls to level platform and lower boom.
    3. Repair issue that caused the malfunction and correct leveling sensor per the Field Service Kit Z1562 instructions.
  3. Always follow inspection and maintenance requirements as specified in the manuals.

Dear Terex Equipment Owner,

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

Terex is recalling certain 2014-2019 TM vehicles. The limit switch was installed upside down and may not stop platform level movement if the platform level exceeds 15 degrees as intended, potentially causing uncontrollable movement.

 

REASON FOR NOTICE

SN681 is for the platform leveling system on Terex TM end mount aerial devices. One of the two basket level limit sensors at the boom tip may have been assembled upside down. The limit sensors prevent the platform from going more than 15 degrees from level if the electrical system malfunctions. The incorrect mounting of the level sensor may cause an out of level basket to continue moving more than 15 degrees out of level. If the leveling system malfunctions it may cause the occupants to fall from the platform, increasing the risk of an injury.

 

WHAT TEREX WILL DO

No parts are required to reposition the sensor if required. Terex will provide Field Service Kit Zl 562, sensor repositioning and testing instructions, and labor at no charge to the customer.

  2. Inspect the unit to determine if your unit has an incorrectly installed level sensor.
  1. If your unit has both sensors mounted with the light colored potting visible, this bulletin applies. Correct following the instructions in Field Service Kit Zl 562. Take a picture before correcting the issue and another picture after correcting the issue. Send both pictures with the completion form including the serial number and date of correction to [email protected].
  2. If your unit has the light colored potting visible only on the top sensor, and the wires coming out of the sensors below the mounting screw this bulleting does not apply and use can continue without restriction.

 

CONTINUED USE

  1. Inform the users of the content of this bulletin and remind them of the daily pre-shift inspection requirements.
  2. If the leveling system malfunctions and the platform gets more than 15 degrees out of level utilize one of the following procedures to stop the leveling system:
    1. Release the enable lever and use the manual level adjustment control to correct the level of the platform.
    2. From the lower controls shut off the upper controls and use the lower controls to level platform and lower boom.
    3. Repair issue that caused the malfunction and correct leveling sensor per the Field Service Kit Zl 562 instructions.
  3. Always follow inspection and maintenance requirements as specified in the manuals.
