CHECK OUTRIGGER PLACEMENT CONDITION
Always observe followings to prevent serious injuries and death
accidents when placing the outriggers.
• When placing the outriggers, always keep the Machine sternly level
while looking at the level gauge. Occasionally view the level gauge
and make sure to keep the Machine level during the crane works as
well.
• Place the outriggers at a maximum extension condition as the basic
rule.
In case of placing in a non-maximum extension condition for
unavoidable reason, always find the values outrigger middle
extension or outrigger minimum extension values in the rated total
load chart before work.
• Place the outriggers in a style that the rubber tracks are
approximately 50 mm above the ground.
• Make sure all of the outrigger position pins are securely fixed.
CAUTIONS WHEN PLACING OUTRIGGER
• Do not let people approach nearby when placing the outriggers.
Otherwise, serious accidents for instance the outrigger support
catching a foot may occur.
• Always set the emergency stop cancel switch at side of the
instrument panel to OFF (auto) position before outrigger operation.
Do not attempt any outrigger operation with the emergency stop
cancel switch at ON (cancel) position.
Inspections and maintenance works are the only occasions where
the emergency stop cancel switch is set to ON (cancel) position.
CAUTIONS HIGH TEMPERATURE OIL WHEN WORKING WITH CRANE
When hydraulic oil temperature exceeds 80 degrees, high pressure
hoses and seals can be damaged by heat, and it may cause burn by
spouted oil.
If temperature of hydraulic oil becomes over 80 degrees, stop
operation and wait until the oil cools down.
Continuous hook raising / lowering operation at high working lifting
height and a long time accelerated operation are easier to raise oil
temperature. Especially be careful for these operations.
