Hot water pressure washers are ideal for removing grease and oil from equipment and very dirty surfaces. This video and guide will show you the proper startup, operation, and shut down procedures for an electric hot water pressure washer.

Before You Begin → Safety First

1. Never operate this pressure washer in an enclosed area. Always make sure there is adequate ventilation.
2. Wear safety goggles and closed-toe shoes, and protect yourself from the possibility of direct spray.
3. Do not come in contact with the motor or heat exchanger.
4. Make sure the pressure washer is on a flat surface.
5. Check the pump oil level before each use. It is recommended to use Mi-T-M pump oil or a 30W non-detergent oil.
6. Add either #1 or #2 diesel fuel or kerosene to the burner supply tank.
7. Connect a garden hose to the pressure washer, and the other end to your water supply.
8. A 20-40 PSI inlet pressure supply is required.
9. Now connect the male end of the high-pressure hose that comes with the unit into the coil outlet on the pressure washer.
10. Make sure the trigger gun is in the ‘locked’ or ‘off’ position.

Getting Ready → Preparing The Equipment

1. Select the high-pressure nozzle best suited to your cleaning task.
2. Pull back the collar, attach the nozzle, and release the collar, making sure it snaps into place.
3. Plug the machine into a properly grounded outlet, and make sure the GFCI is set.
4. Turn on the water, and move the trigger gun lock to the ‘on’ position.
5. Squeeze the trigger on the gun to purge the system of excess air before starting the unit.

Ready To Go → Starting The Pressure Washer

1. Turn the pump switch to the ‘on’ position.
2. Make sure the burner switch is in the ‘off’ position.
3. Right now, the unit is operating as a cold water pressure washer. It is important the unit is not in bypass mode for more than two minutes.
4. To operate as a hot water pressure washer, move the burner switch to the ‘on’ position.
5. Adjust the thermostat to the desired temperature and squeeze the trigger gun.

Extra Cleaning Power → Using Detergent

1. For even better cleaning power, use Mi-T-M detergent that is specifically developed for use with your hot water pressure washer.
2. First move the burner switch to the ‘off’ position.
3. Put the detergent hose into the detergent container and open the detergent valve on the pressure washer.
4. Squeeze the trigger gun.
5. After using the detergent, close the detergent valve and rinse the surface thoroughly.

Project Completion → Turning The Unit Off

1. Be sure to cool down the coil of your pressure washer by turning the burner off, and squeezing the trigger for about 60 seconds, or until the metal lance feels cool to the touch.
2. Turn the pump switch to the ‘off’ position and turn off the water supply.
3. Squeeze the trigger gun to release pressure.
4. Disconnect the high pressure hose and garden hose.
