BE CAREFUL OF TRIPPING ON UNSTABLE GROUND
Always observe the following to prevent serious injuries and death accidents when travelling over an
unstable ground for unavoidable reasons.
• Do not enter soft ground area. The machine may get stuck.
• The ground near cliff, roadside and deep gully is unstable, so avoid going near such ground as much
as possible.
The machine may trip or fall when the ground loosens due to mass and/or vibration of the machine. Be
especially careful after rain, use of dynamite, or earthquakes, as the ground will be unstable.
• Avoid going near the earth fills or vicinity of dug gutter that are instable.
Crumbles caused by mass and/or vibration of the machine may cause the machine to tilt.
CAUTIONS WHEN TRAVELLING SNOW COVERED OR FROZEN GROUND
ALWAYS observe the following to prevent serious injuries and death accidents when travelling over
snow covered ground or frozen road for unavoidable reason.
• The snow covered grounds and frozen roads cause slips even when the inclination is small, so
decrease the speed when travelling and avoid sudden starting/stopping/slewing. Uphill and downhill
are especially likely to cause slips and thus dangerous.
• Frozen ground tends to be weak with the increase of atmospheric temperature, and may cause the
machine to tumble or obstruct the operator to get off. Be very careful.
• Moving into an area covered with deep snow may cause the machine to tumble or dive into the snow.
Be cautious of erroneously deviating outward from the road shoulder or driving into a snow drift.
• Running on a snowbound site may encounter the risk of tumbling or collision because of an invisible
road shoulder or snow-covered installations. Be very careful.
• Refrain from directly touching metal surface with your hands or fingers in cold and harsh weather
conditions.
Touching metal surface may result in skin freezing to the metal surface.
• Remove snow and/or ice laid on the machine that causes the safety nameplates to be hard to read. Be
especially careful to securely remove those that are on the boom and thus may fall.
CAUTIONS WHEN PARKING
• For parking, select an area with flat and solid ground.
• For parking, select an area without the risk of landslide, rock fall
and water submersion.
• When parking, set the machine to the “travelling posture” as
shown in the figure at the right.
• Make sure the boom is fully lowered and retracted.
• When parking the machine for a short period of time, fix the
hook block in the retracting position at the tip of the boom.
When parking for a long time, fix the hook block in the hook
holder at the front end of the upper slewing body.
• When inevitably stopping the machine on an inclined area, strictly
observe the following:
• Make sure the boom is fully lowered and retracted.
• When parking the machine for a short period of time, fix the
hook block in the retracting position at the tip of the boom.
When parking for a long time, fix the hook block in the hook
holder at the front end of the upper slewing body.
• Direct the boom toward the valley.
• To keep the machine immobile, apply a block as a chock.
• When leaving the machine, strictly observe the following:
• Set the lock lever (1) to “LOCK” position (L), and stop the
engine.
• Apply all locks. Do not fail to remove the starter key to prevent
the machine from operated by other personnel without
approval, and keep it in a specified place.
