Parking Recommendations
Always park the crane in the proper area. Park the machine on wooden planks. The planks
will keep the tires from freezing to the ground.
Battery Recommendations
The temperature of the batteries affects the battery’s cranking power. When the battery is
too cold, the battery will not crank the engine, even though the engine is warm. Batteries
may be stored in a warm environment or use of the Battery Blanket is recommended.
Keeping the battery warm by use of the “Battery Blanket”, specified in
Cold Weather
Package Specifications on page 124 , will maintain the battery’s cranking power.
NOTE: Make sure your battery blanket voltage matches your source voltage.
Whenever an engine is being operated in cold weather, use a battery charger to keep the
batteries charged. A full charge prevents the batteries from freezing.
Be sure to keep your batteries charged to a correct specific gravity of 1.250 or above.
Tire Inflation Recommendations
Make sure your tires that are inflated to the correct pressures for the cold temperatures. If
tires are below the recommended pressure they will have a shortened life. A tire that is
inflated to the correct pressure in a 18°C to 21° C (64°F to 70°F) shop area will have a lower
tire pressure in freezing conditions.
Terex recommends the use of dry nitrogen gas to inflate the tires for cold conditions. When
nitrogen gas (N2) is used, there will not be a build up of ice crystals around valve stem
which could hold the valve open.
Tire inflation should be done in a heated shop area. The tire bead will seat better when the
tire bead is warm. The initial tire pressure should be 15% to 20% higher than the operating
pressure in order to seat the bead against the rim. Deflate the tires to operating pressure
before operating the crane. The contact surface of the tires will become flat in cold weather
when a machine is parked. To return the tire to a normal shape, move the machine gradually.
