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 driver's blind spot, especially follow
uctions and signs of the work supervisor and
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
• Remove snow from and defrost the surface of the slewing gear, boom and around winch, and
ensure that their movements before starting work.
• Check the brake of winch 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 of engine warm-up, refer to "OPERATION 3.4.1 WARM-UP OPERATIONS FOR
ENGINE" and "OPERATION 3.4.2 WARM-
UP OPERATIONS FOR HYDRAULIC
EQUIPMENT".
• 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.
