Follow these best practices to make sure your machine is ready for winter.
Check the label to make sure you’re using coolant that complies with ASTM standard D-621, with a freeze point low enough for your climate. If coolant freezes, it can crack the engine block and ruin the engine.
Fuel conditioner prevents your fuel from freezing and makes sure your engine starts in the cold. Check the manufacturer’s recommendations for the amount of conditioner required. Match the fuel conditioner to the type of fuel you’re using (e.g., low sulfur).
If the fuel filter is clogged, moisture can build up and freeze in the winter, causing your machine to run improperly or fail to start. Empty the water traps in the filters before cold weather arrives. To avoid downtime, keep an extra set of fuel filters in your cab.
Diesel engines spray ether into the air system to help the engine start in cold weather. For older machines that have ether spray bottles, check the bottle to make sure it isn’t empty. For new machines with an automatic ether system, inspect the connections and hoses for cracks or loose connections.
Block heaters keep fluids at the right temperature and viscosity. If it isn’t working, the oil can thicken, making it harder to turn the engine over and adding stress on the battery. Plug in the block heater to check it, and then touch the hoses to make sure they are warm.
Large dust particles and debris can build up during the summer and should be removed. Otherwise, snow and ice could collect around them, allowing moisture into the air system, which could cause engine failure.
Corrosion around battery connections causes less voltage to be transmitted, and increases the strain on the battery. Corroded connections can drain the battery, preventing your machine from starting. Periodic inspections for corrosion reduce the chance of having a drained battery.
If you have a diesel engine, either drain it or leave it completely full during winter months. Draining the fuel tank takes time and effort but eliminates the possibility of condensation forming in the fuel tank and spreading. Condensation can clog the fuel filter, which can clog fuel lines, carburetors, and injectors.
Run your machine’s engine after cleaning the engine and replacing the oil so that a protective film of oil coats the internal parts. The oil coating acts as a rust preventative. Pour a 50/50 mixture of water and antifreeze into the coolant system before running as well, to protect the cooling system to -34°F.
Never store discharged batteries. Colder temperatures slow the discharge rate of fully charged batteries.
Avoid starting the machines in extremely cold weather. Find a time when temperature is above freezing to start the machine and fully warm hydraulics after the engine comes to operating temperature.
The result can be powertrain damage.
If you can’t keep your machine inside when it’s not in use, at least keep a weather resistant tarp over the engine. With snow comes condensation, which can cause problems for the entire engine.
Cold weather makes the earth harder, and frost can penetrate roadways and aggregates to make utility, road, and crushing jobs much more difficult and time consuming. Winter months have less daylight, so manage your time wisely.
It is imperative to keep jobsites neat and clean during winter months. When not working, leave a layer of snow on the ground—to keep frost from penetrating the ground the snow will actually insulate the ground beneath. When working, make sure to clear all snow and ice to avoid accidents.
Clean up debris or equipment that will be hidden by fallen snow. Mark any areas of concern with reflective stakes, so snow removal crews can easily identify and stay away from those areas.
Frozen chunks of ground need to be placed in designated areas. The frozen chunks of earth contain water that can cause major problems in the spring, such as sinkholes.
Make sure you are using high quality winter diesel fuel. The fuel conditioner should match the type of fuel you are using (e.g., low sulfur) and should be approved by manufacturer.
Make sure block heaters and cold weather starting devices are working properly.
Let machines come up to operating temperature before working.
Keep an extra fuel filter in the cab, and follow installation instructions in your operator’s manual.
Check for ice or snow buildup in exhaust or intake if applicable. Inspect and clear ice or snow from throttle and brake area.
Steering response on equipment with hydraulic steering may become very slow at low temperatures, even when the correct oils are used. Once the engine is started, let the machine idle until the engine reaches operating temperature.
Mount and dismount your machine using three points of contact. Remember that you are working with snow, and ice slips and falls are a common cause of injuries. Wear your seatbelt when operating equipment and stay alert.
