Truck Modification Safety

Modifications, including welding, affecting capacity or safety must have prior written approval from the manufacturer per OSHA.

Clark will not approve:

  • Mico brake locks
  • Toggle ignition switches
  • Jib boom or similar attachments
  • Welding on the upright
  • Removal of overhead guard, seat belt or safety seat
  • Use of non-CLARK parts

Any modification, including addition of attachments, which affect capacity will require a new data/capacity plate.

Check with your CLARK dealer before making any modifications.
