CAUTIONS WHEN WORKING ON A SLOPE
When inevitably perform operation on a slope, provide an earth fill
(B) to create a horizontal, solid and strong footing for installing the
machine in order to prevent it from tumbling.
Attempting a diagonal hoisting without ensuring the horizontal
installation of the machine not only disturbs the normal functioning
of the moment limiter (overload prevention device), but also affect
the machine with an unexpected force, resulting in tumbling or
damage of the machine.
FOLLOW INSTRUCTIONS AND SIGNS WHEN WORKING
• When operating the crane, appoint a work supervisor and mutual
signs beforehand, and follow the work supervisor and signs during
operation.
• When operating at a operator’s blind spot, especially follow the
instructions and signs of the work supervisor and operate with
caution.
• When operating the crane, there is a danger of colliding with
slewing boom and upper slewing body and of the gaps between
movable parts of the derrick cylinder that may catch body parts
such as your arm or finger.
The operator is requested to make sure no one is within the
working radius of the crane before operating.
CAUTIONS UNDER COLD WEATHER
• Defrost and remove snow from the slewing gear, boom and winch. Check their movements before
starting work.
• Check the winch brake to ensure that it works properly.
• Operating the machine without sufficient engine warm-up causes slow response of the machine to the
operation of levers and pedals, and thus unexpected motion may occur against the operator’s will. Do
not fail to execute the engine warm-up. The engine requires an adequate warm-up time especially in
cold climates.
For details concerning warm-up, refer to “Operation 3.3.1 Warm-up”.
• Avoid revving up the engine immediately after starting it.
• Deposited snow within the crane operation range may cause tumbling of unloaded objects or catching
feet of operators around the machine. First remove snow before starting a crane operation.
• In cold weather conditions, check that the load before being hoisted is not frozen to the ground or other
substance. Attempt to hoist without knowing the load is frozen and stuck to the ground or other
substance is dangerous.
• At the end of the work, if substances such as condensation, snow or mud are stuck to the wire
harnesses, connectors, switches, sensors or similar parts, wipe them off and put covers on them. If the
infiltrated condensation and/or similar substance freeze, the machine may operate improperly upon
the next use and cause unexpected accidents.
