1.
Refuel the machine immediately after operation. This will reduce condensation inside the fuel tank.
2.
Park the machine in a sheltered area, if possible. Cover to protect engine, accessories, and controls from snow and ice.
3.
Park the machine on high, dry ground, or on planks or brush. This will prevent the tires from freezing to the ground.
4.
Block up the front loader bucket, to prevent it freezing to the ground.
5.
Clean wet snow or mud from the tires and the hydraulic cylinders before it freezes.
6.
In extremely cold weather, notify Field Maintenance to remove the batteries and store them in a moderately warm area.
Have the batteries reinstalled just prior to starting the engine.
