CAUTIONS UNDER COLD WEATHER
• Defrost and remove snow from the slewing gear, boom and winch.
Check their movements before starting work.
• 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.
• When the battery electrolyte is frozen, do not recharge the battery
or start the engine with another power source. Such act may
cause the battery to catch fire or explode. De-freeze the battery
electrolyte and check for fluid leak before re-charging or starting
the engine by using another power supply.
• 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.
CAUTIONS WHEN STARTING UP USING BOOSTER CABLE
Wrong booster cable connection method may result in fire, so always
observe the following.
• When using a booster cable for engine start, perform the 2-person
operation by one person on the operator’s seat and another on the
battery side.
• When starting the engine using other machine, be careful to
prevent contact between the normal machine and broken
machine.
• Keep the starter switch key of both the normal machine and the
broken machine in “OFF” position when the booster cable is
connected.
• Do not connect to wrong side [connecting (+) to (
−
), (
−
) to (+)]
when connecting the booster cable.
• Start connecting from (+) terminal first, but start disconnecting
from (
−
) terminal (ground) first.
• For the final earth connection, connect to the negative (
−
) terminal
of the battery of the failed machine.
Refer to the description under “Operation 8.3.4 Starting Engine
with Booster Cable”.
• Avoid contact between clips of the booster cable, and contact
between a clip and the machine when disconnecting the booster
cable.
