DO NOT HIT WORK EQUIPMENT
When working in places where there are height limits, such as
G
in tunnels, under bridges, under electric cables, or in garages,
be extremely careful not to hit the boom or arm.
ENSURE GOOD VISIBILITY
When working in dark places, install working lamps and head

allows the operation to be carried out safely.
OPERATE CAREFULLY ON SNOW
When working on snow or icy roads, even a slight slope may
