3.1.18 MACHINE OPERATION IN ADVERSE WEATHER CONDITIONS
1. Operation in Extreme Cold
a. Follow procedures in the section "3.1.7.B Start Up in Cold Conditions" as starting engine may be
difficult due to extremely cold temperatures
b. Use an engine oil, hydraulic oil and diesel fuel designed for use in cold climates. See
maintenance section, "4.3 LUBRICANT, FUEL & COOLANT SPECIFICATIONS" for reference.
Also, keep battery fully charged.
c. Make certain to perform machine warm-up procedures as described in the section "3.1.7
STARTING ENGINE" to prevent premature wear or damage to pumps, motors and other
components.
d. Make certain that the engine coolant mixture is sufficient to keep the machine safe. Take into
consideration wind chill factors when mixing coolant ratios.
e. Keep battery terminals free of ice and snow. Ice and snow could cause the terminals to short
circuit and cause extensive damage to the machine systems. Check the battery electrolyte (acid)
level frequently and fill as necessary with distilled water. If the machine will be left outside
overnight, it is recommended to remove the batteries and store in a warm area.
In regard to above c.:
In extremely frigid climates, covering the radiator is a method to aid the machine warm-up. IF
NECESSARY TO MAINTAIN OPERATING TEMPERATURES, COVER THE OUTER EDGES OF THE
RADIATOR, LEAVING AN OPENING IN THE CENTER PART OF THE COVER - THUS AVOIDING
FAN OVERLOADING. Keep a close watch on the gauge cluster for warning icons during operation. It
may be necessary to use a coolant heater, fuel heater, engine heater jacket, and/or additional battery
power to aid engine starting.
In regard to above d.:
Mix coolant to a protection temperature of 5C degrees (9F degrees) lower than the machine will
experience during operation, storage or transport.
