CAUTIONS UNDER COLD WEATHER
• After end of the work, wipe off and put on a cover 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.
• Remove snow and defrost the slewing gear, boom and
winch. Check their movements before starting work.
• Warm up enough.
Operating levers and switches with a cold engine causes the
machine to be lethargic, and may result in unexpected
accidents.
• Avoid sudden acceleration of the engine immediately after
engine start.
• Increase the oil temperature of the hydraulic circuit by
relieving the oil pressure (let the pressure oil to escape to
the hydraulic oil tank by raising to above the hydraulic circuit
set pressure) by using the operation lever.
Doing so improves the Machine reactions and prevents
improper operations.
• If the battery fluid is frozen, do not charge the battery or start
the engine using other power source.
Such act may cause the battery to catch fire.
Defreeze the battery fluid and check for battery fluid leak
before charging or starting the engine.
PRECAUTIONS CONCERNING DPF REGENERATION
• Exhaust gas will be at elevated temperatures irrespective of the load. Be careful not to get
burn.
• Sound will be generated at the start and end of regeneration control because opening degree
of intake throttle and EGR valves have to be controlled. This sound indicates normal
operation.
• The odor of the exhaust gases is different from the conventional diesel exhaust odor.
• During regeneration operation, CO can build up in enclosed or partially enclosed spaces. Pay
attention to avoid CO poisoning.
