Operation Instructions
Before operating the Safe-Stop 180 TMA, thoroughly read
and understand these instructions and the safety section
of this manual. Verify that the system is properly in-
stalled and in working order. For proper impact perfor-
mance, the TMA must be equipped with one Safe-Stop
Type A Cartridge and one Safe-Stop Type B Cartridge, in
their proper positions as shown in Figure 19 on page 15.
The Safe-Stop 180 TMA has been equipped with a hy-
draulic pump that can be used to fold the TMA from its
extended position. The controls are located on one side
of the support frame. A set of controls is also located in
the truck cab. The controls on the support frame should
be mounted to the non-traffic side of the system. To
change the mounting, see "Connect the Lights and Con-
trols" section in the Installation Instructions.
While folding or unfolding the Safe-Stop 180 TMA from
outside the cab, the operator must stand on the non-
traffic side of the truck. Always stay clear of moving parts.

CAUTION: Make sure the area above and be-
hind the system is clear of all objects be-
fore proceeding. Under no circumstances
should anyone be allowed behind the system
when it is being folded or unfolded. When
operating from the cab, always be aware of
objects behind the Safe-Stop 180 TMA.
Note: The Safe-Stop 180 TMA will not operate
unlass the cab control pendant is plugged in.
Folding the system: There is one "FOLD" button on each
set of controls. To fold the system up, press and hold the
"FOLD" button for a few seconds. Once the system has
begun to operate, it will completely fold and then shut
off, without the need to continue holding the button.
Unfolding the system: There is one "UNFOLD" button on
each set of controls. To unfold the system, press and
hold the "UNFOLD" button for a few seconds. Once it has
begun to operate, it will completely unfold and then shut
off, without the need to continue holding the button.
The system will not serve its intended purpose when
folded. The TMA must be unfolded during shadow or
barrier vehicle operations. The truck and Safe-Stop 180
TMA combination offers the best driving characteristics
when folded. Driving with the system in the folded posi-
tion is permissible and recommended during restricted
city driving and extended high-speed travel. Be sure to
unfold the system either before, or as soon as possible
after, entering into a site. Remember that it is recom-
mended that the support vehicle be stopped for TMA fold-
ing and unfolding.
The Safe-Stop 180 TMA should only be operated while
the truck is at rest. Jarring or severe bumping of the sys-
tem while folding or unfolding may cause damage to the
system or injury to the operator.
