Assembly
Read and understand all instructions before beginning assembly.
Theweightof thevehicleshallbe between6,120kg and11,340kg fortested performance.
Refer to the Australian Design rules – Vehicle Standards Bulletin 6 (VSB6) for the Australian
regulations regarding chassis modifications and attachments. The system may be attached to the
truck by attaching parts to the vehicle frame, using specified hardware in the VSB6. Do not weld
any TMA components to the truck frame. It is recommended the use of side fishplate to mount the
unit to the chassis (as per page 13, figure 8). The addition of the side fishplates allows for the
removal and replacement of the mounting system, if the unit was to be damaged in a TMA impact.
Use certified or professional welders to ensure durable attachment of the TMA system.
Disconnect the truck battery before any welding on truck or TMA.
The truck frame must be suitable and accessible for mounting aTMA. If there are any questions
regarding the suitability, contact the Customer Service Department for input as to your
specific application.

Revision ANovember 2019
Preparation
1A) Assembly Must Be Performed On Level Surface
The system’s framework is very heavy.
1B) Truck Ballast
Use abubble level to verify that the truck is parked on alevel surface. The truck shall be as close
to the final driving weight as possible. If ballast must be added to achieve the minimum weight, add
it at this time. Ballast must be properly anchored to the truck to keep it in place during an impact.
Ideally, an adequately sized truck, that requires no ballast, should be used. Because the 910
kg weight of the rearward protruding TMA is supported by the back of the shadow vehicle,
care must be taken not to exceed the manufacturer's published maximum axle loads. To ensure
that the driving characteristics of the vehicle are maintained, the manufacturer’s recommended
center-of-gravityzone shall be followed completely.
2) Interference Check
Before attempting to assemble the Underride, check for interference concerns.
The TMA folds so the Impact Face is very closeto themounting location(p. 24, Figure 25).If you
are not using astandard Socket Receiver Hitch Underride skip to Step 8.
Temporarily position the Underride Socket Receiver undertruckframe as shown(p.13,Figure8)
and check for interference concerns. Interference concerns with tail lights, springs, dump bodies
(in the folded or unfolded positions), etc., shall be corrected before proceeding.

3) Underride Assembly
With the truck at its actual driving weight and parked on a level surface, measure the distance from
the ground to the bottom of the truck frame. A distance of 711mm ± 25 mm is required. Spacer
Tubes may be added to the bottom of the frame to achieve this height (p. 14, Figure 10).
Note: The truck’s springs may settle with the weight of the TMA, sometimes as much
as 50 mm. Adjust the height to compensate for anticipated settling.
Measure distance from the back end of the frame forward to the rear-most leaf spring hanger. Look
for any obstruction on the bottom of the frame that may interfere with the Socket Receiver. A
minimum of 305 mm is required (Underride Assembly drawing on p. 60).
It is important to check for obstructions before mounting the socket receivers. Position the Socket
Receiver at the rear end of the frame so that the 76 x 387 mm flat bar is along the outside of the
frame member and the Socket Receiver Assembly is flush with the end of frame. If spacers are
required, weld them to the Socket Receiver and lap the Spacer Splices (pieces of 10 x 51 x 103
mm flat bar) across the Socket Receiver and Spacer at the rear most location (p. 47). The top of
the Socket Receiver shall be 711mm ± 25 mm from the level ground for proper system height (p.
14, Figure 10).
Important: Welding must be performed by professional or certified welder.
All welds must be then primed and painted.
Australian chassis modification regulations may differ to that explained in this manual. It is always
recommend that you follow your local design rules when modifying the vehicle's chassis and
installing any TMA. Ensure that the vehicle and any modifications carried out meet the compliance
requirements for your region.
To provide addition strength to the rear of the chassis, it is recommend that the Underride Socket
Receivers have the flat mounting bar removed, then weld the Underride Socket Receivers to a large
16mm thick steel fishplate (similar as shown below in figure 8). Remember to position holes in the
fishplates for the pins to pass through the socket receiver. Then bolt the fishplates to the chassis and
if possible, also the tray sub frames. Once bolted on, install an extra cross-brace on the inside
between each Underride Socket Receiver. This will provide a rigid rear mount assembly (without
welding to the chassis), while allowing the removal and replacement of the receivers if damaged in
a TMA impact.

An example of modified Underride Socket Receiver mounts are shown below.They are a
suggested guide on how to install the Underride Socket Receivers without welding to the
vehicle chassis.
Installation of the Underride Socket Receivers may vary on each vehicle due
to chassis, suspension and body variations. You should allow seek the
direction of a engineer as to the best installation for your selected vehilce,
prior to beginning installation.

be necessary to add shims to the Socket Hitch in order to level the Frame (Figures 3 & 12).
8) Connect the Lights and Controls
Locate the female TMA Socket Connector in aconvenient location on the truck so that lifting or
lowering the TMA will not damage the electrical cable. Make sure that the electrical cord on the
TMA can reach this location.
For support vehicles with combined tail and clearancelights, connect a jumperbetweenpins 2 and
6on the backside of the male TMA plug connector (VIEW A-A and Figure 14). Connect the
7-pinplugtothesocket on thetruck.
The truck battery must be of the proper voltage. The SS180®Mis available in 12 and 24 volt
versions. Be sure the system and truck are compatible. Use standard safety practices when
attaching the battery cables. Attach positive terminal first when connecting and remove the
negative cable first when disconnecting the battery. Do not run the battery cables around sharp
corners, metal work, or in other areas that could pinch or cut the cables. Connect the battery cable
to the pump motor. Consult the Hydraulic Assembly drawing package.
Caution: For over-current protection, the positive cable lead coming off the
truck battery should be protected with a70 amp fuse or circuit breaker within
450mm of the truck battery.
The controls at the rear of the truck are mounted to bothsides of theSupportFrame.Securely
fasten cable ties to secure any loose wiring to the SS180®Mframe. Mount the cab switch box
