If you have to perform Pick & Carry by
necessity, the load must be within the values
shown in the "Pick & Carry rated total load
chart" and Pick & Carry posture must be
strictly respected.
Not observing these cautions on Pick & Carry
can cause serious accidents.

Cautions on Worksite
The following ground and location present the
machine overturning hazard. Do not approach
those locations or perform Pick & Carry at those
locations.
Check the condition of the road surface and
ground in advance and place someone to guide
you at the hazardous location or the location with
poor sight.
• Slope, soft ground such as swamps, ground
with many obstacles, ground with distinct
irregularity such as river beds
• Near deep gullies and road shoulders
• Under water, shallow water, snowy area, frozen
road
Cautions on Operations
The following travelling operations involve the
danger of overturning the machine. Never
perform these operations.
Always be seated to the operation seat and
carefully perform the Pick & Carry operation.
• Do not perform the crane operation while
travelling. Keep Pick & Carry posture.
• Do not hold the load high. Hold the load near
the ground so that the load does not slew.
• Do not perform sudden starting, sudden stop,
or sudden steering. The load will slew and will
be dangerous. Keep the engine at low speed
and travel slowly.
• Do not go over an obstacle. The machine will
topple over easily. Always travel on the path
avoiding the obstacles.
