Decrease speed to a safe setting and avoid
sudden starts and stops.

WARNING! Exposure Hazard. Do not touch
metal surfaces with bare skin in cold
weather. Always wear gloves when working
in cold weather.
Use extreme caution when operating in cold
weather. Frozen ground surfaces become soft
when air temperature rises. The load that is to be
hoisted could be stuck to the ground.
NOTICE: When cold, always perform the
warm-up operation. Sufficient warm-up
operation is necessary when starting in cold
temperatures. Insufficient warm-up operation
will slow down the movement response of the
travelling system or crane system to the
operation levers, resulting in machine damage
or personal injury.
NOTICE: Hydraulic oil operating temperature is
50° to 80°C. When operating at low
temperatures, increase the temperature of the
hydraulic oil to a minimum of 20°C. Increase the
hydraulic oil temperature by relieving the oil
pressure. Allow the oil to flow to the hydraulic oil
tank by using the operation lever. This will
improve the machine hydraulic actions and
prevent abnormal operation.
NOTICE: After daily operation in cold weather,
wipe and clean all condensation, snow, ice and
mud from the wire harness, connector (1),
switches and sensors.
