PRECAUTIONS WHEN TRAVELLING ON
SNOW OR FROZEN GROUND
Always observe the following points to prevent
serious injuries or fatal accidents when travelling
over snow-covered ground or frozen roads for
unavoidable reasons:
• Travel as slowly as possible and avoid sudden
starts, stops, or turns when travelling on snow
or frozen surfaces. There is a risk of slipping
even on slight inclines. Travelling up and down
slopes is especially dangerous due to the risk
of slipping.
• Take care on frozen ground, as it tends to
soften as the temperature rises, causing a risk
of the machine toppling or becoming stuck.
• There is a risk of the machine toppling or
becoming buried if driven into deep snow. Be
careful when travelling away from road
shoulders or into snow drifts.
• Take care when travelling on snow, as there is
a danger of toppling and collision if road
shoulders or other structures are hidden by
snow.
• Do not directly touch metal surfaces with your
hands or fingers in cold conditions.
Touching metal surfaces of the machine in
freezing conditions may result in skin freezing
to the metal surface.
• Remove snow or ice build-up on the machine,
as this may make the safety nameplates hard
to read. Snow or ice on the boom in particular
should be completely removed, as there is a
risk of it falling off and hurting someone.
PRECAUTIONS WHEN PARKING
• When parking, select a location with flat and
solid ground.
• When parking, select a location without a risk
of landslide, rock fall, or flooding.
• When parking, arrange the machine in its
"travelling posture" as shown in the figure.
Make sure the boom is fully lowered and
retracted.
When parking the machine at the worksite,
secure the hook block in the stowed position
at the tip of the boom. When parking it away
from the worksite, secure the hook block to
the hook holder at the front end of the upper
slewing body.
• Strictly observe the following points as well
when stopping the machine on a slope for
unavoidable reasons:
Make sure the boom is facing downhill.
Chock the machine with blocks to prevent it
from moving.
• Strictly observe the following points when
leaving the machine:
Set the lock lever (1) to the "LOCK" position
(L), and stop the engine.
Be sure to close the cab door and lock
everything. Always remove the starter key to
prevent the machine from being operated by
unauthorized persons. Store the key in a
designated place.
