Cleaning and Preparation

Before storing your Hart pressure washer, it’s crucial to give it a thorough cleaning. Start by detaching the hose and nozzle from the machine. Then, run clean water through the system to flush out any remaining detergent or debris. Make sure to disconnect the power supply and let the machine cool down completely before performing any cleaning.

Use a soft brush to remove any dirt or grime from the exterior surfaces. Pay special attention to the vents and cooling fins to ensure proper airflow during operation.

Inspect the washer for any signs of damage or wear. Check the hoses, nozzles, and any connections for leaks or loose parts. If you notice any issues, address them before storage or seek professional assistance. Cleaning the machine helps prevent dirt or chemicals from clogging the system and minimizes the risk of corrosion during storage.

Drain and Flush the System

To prevent any residual water from freezing and causing damage during the off-season, drain and flush the washer’s system. Begin by removing the spark plug wire to eliminate accidental starting. Then, locate the drain plug or valve (usually found near the base of the pump) and remove it to allow the water to drain completely. Consult the owner’s manual for specific instructions regarding your Hart washer model.

After draining the water, connect a short garden hose to the water inlet of the pressure washer and turn on the water supply. Run clean water through the machine for a few minutes to flush out any remaining residue. This step helps prevent any detergent or cleaning solution from damaging the system over time.

Lubricate Moving Parts

Applying lubrication to the moving parts is essential for maintaining its performance and preventing rust and corrosion. Prior to storage, use a lubricant recommended by the manufacturer to coat the pump, engine, and other movable components. Remember to follow the manufacturer’s instructions and guidelines, as using the wrong type of lubricant can damage the equipment.

For the pump, remove the spark plug and add a few teaspoons of pump lubricant or engine oil into the spark plug hole. Gently pull the starter cord a couple of times to distribute the lubricant inside the pump. This will prevent the seals and pistons from drying out and cracking during storage.

For the engine, remove the spark plug and add a small amount of engine oil directly into the cylinder. Slowly pull the starter cord a few times to distribute the oil throughout the engine.

Protect the Pressure Washer

Now that your Hart pressure washer is clean, drained, and lubricated, it’s time to protect it from dust, dirt, and other elements that can potentially harm its functioning during the off-season. Follow these steps to protect your machine:

Store it in a Dry and Well-Ventilated Area

Choose a storage location that is protected from rain, snow, and extreme temperatures. Avoid storing it in direct sunlight, as prolonged exposure can lead to fading and damage to plastic components.

Use a Breathable Cover

Before storage, remove the battery from the device and store it separately in a cool, dry place. Check the battery’s charge level, and if it’s low, recharge it to about 50–75% capacity.

Storing a battery fully charged or completely depleted for an extended period can lead to reduced performance and lifespan. Additionally, inspect the battery terminals for any corrosion and clean them using a wire brush or a battery terminal cleaner. Place the battery in a sturdy, non-conductive container, and avoid storing it directly on concrete surfaces.

Pressure Washer Winterization Tips

If you live in an area with freezing temperatures during the off-season, take extra precautions to winterize your Hart washer. For storing pressure washers for winter Freezing water can cause severe damage to the pump, hoses, and other components.

Seal any openings or gaps in the storage area to minimize entry points. You can also place mothballs or cotton balls soaked in peppermint oil near them, as these scents are known to repel pests. Regularly inspect the storage area for signs of pest activity and address any issues promptly.

Moisture is the enemy of your pressure washer during storage. To ensure your machine stays dry and moisture-free, consider using a dehumidifier or moisture-absorbing products in the storage area. These can help reduce humidity levels and prevent condensation, which can lead to rust and mold growth.
