G
Risk of accidents due to outrigger beams sliding out!
Completely retract all outrigger beams and secure them. This prevents the
outrigger beams sliding out when driving around corners and causing seri-
ous accidents.
G
Risk of accidents if outrigger beams cannot be seen
Cordon off the area where you intend to extend and retract the outrigger
beams. Nobody is allowed to be in this area.
Observe the moving outrigger beams or have them observed by a banks-
man who is in visual contact with you.
G
Danger of overturning if improperly supported
Always extend all outrigger beams to the required outrigger span required
for the specified rigging mode, even if you are only working on one side.
Otherwise the rear stability for the rigging mode according to the displayed
rigging mode is no longer guaranteed.
S
Risk of damage to the outriggers
Before extending the outrigger beams, always check whether they have
been released. This prevents damage to the locking bars.
S
Risk of damage to driver's cab
Always bring the outrigger pads to the driving position before retracting
the outrigger beams.
This prevents the outrigger pads damaging the driver's cab when the
outrigger beams are retracted.
