all obstructions on the ground and overhead and
avoid them.
Always, before operating any function, check the
area around and overhead for any obstructions or
electrical conductors.
Multifunction Controls
The UpRight SB-80 employs the use of multifunction
controls. This means that functions can operate at
full speed simultaneously.
The turret may be rotated while driving if necessary
to make turns in tight areas*. All other boom func-
tions will not operate while driving.
*NOTE: European model only. On Domestic mod-
els, all functions are available while driving.
