The SS180
®
M has been equipped with a Hydraulic Pump to fold / unfold the unit. The controls
are located on both sides of the Support Frame. A set of controls may also be located in the truck
cab.
While folding or unfolding the SS180
®
M from outside the cab, the operator must stand on the
non-traf
fi
c side of the truck. Always stay clear of moving parts. Never stand underneath the TMA.
Folding and Unfolding the System
Caution :
Make sure the area above and behind the system is clear of all objects
before proceeding. Under no circumstances shall anyone be allowed behind
the system when it is being folded or unfolded. When operating from the cab,
always be aware of objects behind and above the SS180
®
M.
Folding and unfolding the system: The Rocker Switch operates by pushing and holding the switch
down on the end towards the desired position.
The system will not serve its intended purpose when folded. The SS180
®
M must be unfolded
during shadow or barrier vehicle operations. The truck with a folded SS180
®
M offers better driving
performance. Driving with the system in the folded position is recommended during restricted city
driving, driving to and from the work site, and when there is a period of extended high-speed travel
between work sites. Be sure to unfold the system before entering a site. The support vehicle must
be stopped each time the SS180
®
M is folded or unfolded.
Important:
The SS180
®
M hydraulic system is only to be operated while the truck
is stopped. Jarring or severe bumping of the system while folding or unfolding will
cause damage to the system and possible injury to the operator.
The pump is not intended for continuous operation. The folding and unfolding operation
has an automatic stop feature. Hold the rocker switch down until the pump motor stops
at the fully folded or unfolded position.
