Before you pull the trigger, ensure your setup is solid to prevent pump damage:

: If you live in a freezing climate, never store the unit with water inside. Run a small amount of pump guard or antifreeze through it, or store it in a heated garage. Frozen water expands and will crack the aluminum pump casing. ⚠️ Safety First

: Before turning the power ON , squeeze the gun trigger until water flows out in a steady stream. This removes trapped air. 🛠️ Key Operating Tips

: Check the mesh filter where the garden hose connects. If it's gunky, your pump won't get enough water.

A: The manual specifies a maximum ambient temperature of 104°F (40°C). It gives no specific run time limit, but common sense from the manual dictates: after 30 minutes of continuous use (e.g., cleaning a driveway), let the motor cool for 15 minutes. This unit is S1-rated (intermittent duty).

Only use splash-proof extension cords approved for outdoor use. Connect the machine to a single socket rather than a multiple-plug adapter to prevent overloading. Water Connection:

The RE115K is a low-maintenance machine, but the manual lists three non-negotiable tasks.
