CAUTIONS UNDER COLD WEATHER
• Remove snow from and defreeze the swing gear, boom and winch
related parts, and check the movements before work.
• Warm up enough.
Attempt to operate the operation levers and switches without
enough warm-up causes the Machine to react dull, and may result in
unexpected accidents.
• Avoid acutely accelerating the engine during short time after
starting the engine.
• Increase the oil temperature of the hydraulic circuit by relieving the
oil pressure (let the pneumatic oil to escape to the hydraulic oil tank
by raising to above the hydraulic circuit set pressure) by using
operation lever. Doing so improves the Machine reactions and
prevents improper operations.
• If the battery fluid is frozen, do not charge battery or start the engine
using other power source.
Such act may cause the battery to catch fire.
Before charging or starting up using other power source, defreeze
the battery fluid and check that failures such as battery fluid leak do
not exist.
• 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 freezes, the
Machine may operate improperly upon the next use and cause
unexpected accidents.
