PRECAUTIONS DURING SEASONAL CHANGES
Where temperature changes are drastic or seasonal especially in colder climates it is necessary to take some countermeasures
meant to limit any damage resulting from low or extremely high temperatures.
COLD SEASONS
When the end of the work day approaches especially during extremely cold weather it is important to follow several simple
steps to assure a good start-up the next work day.
• Remove any mud or water from the machine especially the undercarriage area.
• Park the machine in a protected area if possible.
• Drain any condensation from filters and water traps. See “DRAINING WATER SEPARATOR” on page 3-29.
• If possible, remove the battery and store in a warmer location if temperatures will be extremely cold.
• Always allow the machine time to warm up during cold seasons See “WARMING THE MACHINE UP” on page 2-33.
FUEL AND LUBRICANTS
• In colder climates it is advisable to use winterized fuel DSTM D975 N 1 when ambient temperatures are below -10°C
(14°F) (Do not mix gasoline with diesel fuel. This will damage the fuel system)
• Change the engine oil with a suitable viscosity oil for the climate. See “FUEL, COOLANT, AND LUBRICANTS” on
page 3-7.
COOLANT
The required standards for permanent antifreeze are SAE-J1034 and Federal Standard O-A-548D. See “CHANGING COOL-
ANT” on page 3-53.
Never mix antifreezes or add additives to the cooling system.
Remark
Never use flammable liquids in the cooling system.
BATTERY
When ambient temperatures decrease, the battery capacity decreases accordingly and, if the battery charge is low, the electro-
lyte may freeze. Keep the battery completely charged and insulated to protect it from low temperatures so that the machine can
be started without problems the following day.
To Measure The Specific Gravity Of The Electrolyte Refer To The Following Table.
To avoid explosions due to the presence of gas, do not create sparks, smoke or have open flames near the
battery.
