Limitaon and Warnings
TrafFix Devices Inc. (TDI), in compliance with the Manual for Assessing Safety Hardware
(MASH) recommended procedures for the Safety Performance of Highway Features. TDI
contracts with ISO accredited testing facilities to conduct crash tests, evaluation of tests, and
submittal of results to the Federal Highway Administration for Eligibility for Federal-Aid
Reimbursement. The Scorpion II Metro Truck Mounted Attenuator (TMA) system was tested
to meet the safety evaluation guidelines of MASH. The Scorpion II Metro has been tested at
TL-2 PLUS (50 mph/80 km/hr) speed conditions. These tests are intended to evaluate product
performance by simulating those impacts outlined by MASH involving a range of vehicles on
the roadways. From cars with an approx. weight of 2425 lbs (1100 kg) to trucks with an
approx. weight of 5004 lbs (2270 kg). The Scorpion II Metro TMA is a TL-2 PLUS tested
device is capable of decelerating and stopping light and heavy weight vehicles 2425 lbs [1100
kg] and 5004 lbs [2270 kg] in accordance with the criteria of Tests 2-50, 2-51, 2-52, and 2-53
for FHWA Eligibility (Reference FHWA Eligibility Letter CC-158). TrafFix Devices does not
represent nor warrant that the results of these controlled tests show that vehicle impacts with
the products in other conditions would necessarily avoid injury to person(s) or property.
Impacts that exceed the system’s specifications may not result in acceptable crash performance
as outlined in MASH; relative to structural adequacy, occupant risk, and vehicle trajectory. TDI
expressly disclaims any warrant or liability for injury or damage to person(s) or property
resulting from any impact, collision, or harmful contact with products, other vehicles, or nearby
hazards or objects by any vehicle, object or person, whether or not the products were installed
by third parties. The Scorpion II Metro TMA system is intended to be assembled, and
maintained in accordance with specific State and Federal guidelines. TDI offers a reflective
delineator panel for its TMA line of products. However, the material is only intended to
supplement delineation required by the Department of Transportation’s “Manual on Uniform
Traffic Control Devices” (MUTCD). The appropriate highway authority approved engineer
should be careful to properly select, assemble, and maintain the product. Careful evaluation of
the speed, traffic direction, and visibility are some of the elements that require evaluation for
the proper selection of a safety appurtenance by the appropriate specifying highway authority.

Operang Instrucons
Proper Operaon includes knowledge of TMA use in Work Zones, both Moving and Staonary, 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.
Pre-Use Inspecon
1. Walk around the unit inspecng for damaged, loose, or missing bolts, pins, coer 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 operaon (including arrow/message board if applicable).
5. Cycle the unit from stowed to deployed and back to stowed posion (see direcons below),
ensuring proper sequence and funcon (including arrow/message board li system if aached) pay
close aenon for any binding or “slop” during operaon and that the alarm is funconing
properly.
6. Check road clearance of TMA in deployed mode, to ensure it is in specicaon (12 inches ±1 inch).
7. Ensure that retroreecve sheeng 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 projecle during an
impact.
10. Make sure items in the cab of the vehicle are secure and cannot come loose and become a
projecle should an impact occur.
11. Adjust the headrest properly for the driver of the vehicle.
12. Any deciencies should be corrected before use.

To Raise (“Store”) the Unit for Transport
1. Ensure that both the truck bed and area above the rear of the host vehicle is clear.
2. Locate the desired controller, either the in-cab controller (if installed) or the rear plug-in. If using
the rear plug-in, and it is not already plugged in, plug it into the socket on the TMA near the rear
passenger side of the truck.
3. If the unit is to be transported, ensure that the drop jacks are fully retracted and pinned and that
the swivel jacks are fully retracted and rotated to the stored and locked posion.
4. If using the rear plug-in controller unplug and store in the cab.
To Lower (“Deploy”) the Unit for removal or Use
1. Ensure that both the area above and to the rear of the host vehicle is clear.
2. Plug in the controller (see #2 above) or locate the in-cab controller (if installed).
3. If the unit is being removed, the swivel jacks should be rotated to the deployed posion and the
drop jacks lowered and pinned to the correct height. If the unit is being deployed for use, all
jacks should remain in the stored posion.
4. Being careful to avoid the pinch points, push the “Down” buon unl the TMA is fully deployed
to a horizontal posion.
5. Connue to hold the Down buon for 4 more seconds aer the Arrow/Message Board Li System
(if aached) or the TMA has stopped moving. This will ensure the TMA is fully deployed and the
hydraulic system is at the proper pressure to hold it in posion.
6. Make sure the Arrow/Message Board is displaying the proper message.
Note: TMA must be in the stowed posion for travel to and from the Work Zone

SAFETY INSTRUCTIONS & PRECAUTIONS
A. Before aempng to install or operate the Scorpion II Metro TMA this manual should be read and
understood. Those areas with warnings or cauons should be carefully followed.
B. Before raising or lowering the TMA the operator should check that the area around the TMA is clear and
that personnel are not in or near the area.
C. Before operaon on the roadway, check all 1” diameter pins and bolts at the back-up and hinge areas for
ghtness and excessive wear. Also, check that all coer pins are in place.
D. Check that the two drop jacks are fully retracted and that the safety pins are in place. Also, check that the
crank jacks are fully retracted and rotated to the up and locked posion.
E. For correct operaon of the TMA in the deployed posion (horizontal posion), the TMA should be 12" ±
1” above the ground and horizontal to the roadway.
F. The responsible agency for the support vehicle should check that the following specicaons are met:
The support vehicle should weigh a minimum of 7,300 lbs (3,300 kg). If the support vehicle is ballasted,
the ballast should be properly anchored to the support vehicle frame to prevent movement during an
impact. The support vehicle should be equipped with proper operator safety equipment such as seat
belts, headrest, etc.
G. The support vehicle should have a straight frame design. An over axle (bent) frame design is not
appropriate for use on a TMA support vehicle.
H. Before disconnecng the TMA from the support vehicle, make sure the TMA is in the horizontal posion
with all jack fully deployed
Special Warnings
1. Aer a vehicle impacts the TMA, do not drive the support vehicle with the damaged TMA. Remove the
TMA at the backup and have the TMA transported back to the maintenance yard.
2. Check the TMA model to make sure that the posted speed matches the TMA capacity.
Scorpion II Metro = TL-2 PLUS, 50 mph (80 kph).
