SAFETY
comes fi rst
.
While most hazards that may occur when operating an M2 Series
motorized unit setup can be avoided by using extreme care and common sense, the use
of safety accessories, such as a rest platform and appropriate guardrails and plank support
outriggers, is recommended when areas and activities involve heights or positioning of the
setup that put workers at risk.
Face guardrail supports must be installed when the distance
between the end of planking (or deck, if not using planks)
and the structure is greater than what local regulations allow
or 6" (15 cm) (ex. recess in a wall, end of a building, etc.),
the most stringent of conditions taking precedence over the
others. On all M2 Series motorized units and bridges, the
face guardrail supports can be installed at the
bottom
or
top
outrigger position.

Installation
1-
If there are no outriggers installed, install the outriggers at the top or bottom position,
as required. Refer to p. 95 for instructions on the installation of outriggers. Make sure
not to install any plank stop pins. If outriggers are already installed, remove the plank
stop pins and proceed to step 2.
