Investing in a commercial-grade pressure washer, especially a Hotsy unit from DSG Equipment & Supplies – means you’ve chosen durability and power. But even the best equipment needs routine maintenance to keep it running at peak performance. Proper care not only protects your investment but also extends the lifespan of your machine and prevents costly downtime.

Here’s a quick guide to maintaining your pressure washer the right way.

1. Check and Change the Oil Regularly

Just like any engine-driven equipment, your pressure washer needs clean oil to operate smoothly. DSG recommends:

• Checking engine and pump oil levels before each use.
  
• Changing pump oil after the first 50 hours of operation, then every 500 hours.
  
• Using Hotsy-approved oil for long-term performance.
  

Our service team at DSG can help you identify the correct oil type for your specific model.

2. Inspect Nozzles and Hoses for Wear

A worn nozzle can reduce cleaning power or cause erratic spray patterns. Damaged hoses pose safety risks and can lead to leaks or pressure loss. Check:

• Hoses for cuts, cracks, or bulges.
  
• Nozzles for clogs or erosion.
  
• Hose reel connections for tightness and security.
  

Replace worn parts promptly, DSG carries a full selection of pressure washer hoses, nozzles, and accessories.

3. Flush the System After Every Use

To prevent buildup and freezing, especially in colder months:

• Run clean water through your system after each job.
  
• Use antifreeze or pump saver if storing your washer in freezing conditions.
  
• Never let water sit inside the pump or coil.
  

Ask DSG about winterization services and cleaning detergents to keep your unit in top shape.

4. Clean or Replace Filters

Your pressure washer’s inlet water filter keeps debris from entering the pump. A clogged filter restricts water flow and stresses the pump. Clean it weekly or more frequently in dusty or dirty environments.

5. Schedule Preventive Maintenance with DSG
