Power Washer Recommendations

Pressure Washer Recommendations:

Check oil level and condition:

Possibly the most important aspect of using and maintaining a power washer is checking the engine oil. The oil level should be checked before every use. Most power washer engines have a capacity of less than 2 quarts, with many having a capacity of 1 quart or less. Therefore, even a slight loss of oil through leakage or normal consumption during operation can lead to lubrication issues which could result in increased wear or internal damage to the engine.

Due to the wet environment that most pressure washers are operated in, it is also very important to monitor the oil for signs of moisture contamination.

Many pressure washers have an oil lubricated pump in which the level and condition of the oil should be checked regularly as well.


Check hose connections:

All hose connections should be checked regularly. O-rings will wear and degrade over time which can cause leaks possibly affecting performance or causing injury due to the pressures developed by the unit.

Most pressure washers are equipped with a screen in the inlet hose fitting. This screen should be checked regularly for debris or corrosion buildup which could restrict the volume of water available to the unit. If too much restriction is present it can lead to starvation and or cavitation of the pump causing performance problems and potential damage to the internal parts of the pump unit.

Preparing for storage:

The primary cause of pump damage is freezing of retained water in the pump unit. Therefore, it is very important to make sure all water is drained from the hoses and pump unit when being stored.

A pump lubricant/winterizer is also highly recommended for longer storage periods, especially if freezing conditions are to be expected. When used as specified, these products help to purge remaining water from the pump unit. Most of these products also contain anti-corrosion and lubricating additives which help to keep seals and pumping mechanisms from corroding and degrading during storage.
