Operating Instructions
Proper Operation includes knowledge of TMA use in Work Zones, both Moving and Stationary, including
the proper spacing, to allow for “roll
-
ahead”. Before use, the Operator should have prior knowledge/
discussion of the Work Zone in which the TMA will be deployed and that the TMA model used has been
tested and passed to Test Level 2 PLUS, 50 mph/80 kph. TMA’s should only be operated by individuals
properly trained in their use in work zones.

Use Inspection
1. Walk around the unit inspecting for damaged, loose, or missing bolts, pins, cotter pins and safety
snaps.
2. Inspect for damage to the energy absorbing modules and aluminum tubes, checking for deep
gouges, deep scratches, warping, or cracking.
3. Inspect the steel structure for damage, looking for warping, cracks, breaks or other damage.
4. Inspect all lights for proper operation (including arrow/message board if applicable).
5. Cycle the unit from stowed to deployed and back to stowed position (see directions below),
ensuring proper sequence and function (including arrow/message board lift system if attached) pay
close attention for any binding or “slop” during operation and that the alarm is functioning
properly.
6. Check road clearance of TMA in deployed mode, to ensure it is in specification (12 inches ±1 inch).
7. Ensure that retroreflective sheeting is in place and meets requirements for job.
8.
Check visually for hydraulic leaks.
9.
Check to ensure that there are no loose items on the truck that can become a projectile during an

10. Make sure items in the cab of the vehicle are secure and cannot come loose and become a
projectile should an impact occur.
