• Remove snow from and defreeze the swing gear, boom and winch related parts, and check the
movements before work.
• Check the operation of winch brake.
• Warm up enough. Attempting to operate the operation levers, pedals and switches without enough
warm-up causes the Machine to react dull, and may result in unexpected accidents.
For details of warm up operation, see “Operation 3.4.1 Engine Warm Up”, “Operation 3.4.2
Hydraulic Equipment Warm Up”.
• Accumulation of snow within the working range of the crane can cause turnover of the unloaded load
or the workers around may trip over. Remove snow sufficiently before starting crane operation.
• If the load to be hoisted is stuck to the ground because it is covered with snow or frozen, do not force to
hoist the load. Thoroughly remove the snow or unfreeze before the crane operation.
• After end of the work, wipe off and apply wraps if substances such as condensation, snow or mud are
stuck to the wire harness, connector (1), switches, sensors or similar part.
If the infiltrated condensation and/or similar substance freeze, the Machine may operate improperly
upon the next use and cause unexpected accidents.
