WashR DUO | How to maintain your unit (Maintenance Guide)

To ensure efficient operation and longevity of your Bigboi WASHR DUO, a routine maintenance schedule should be prepared and followed. If the equipment is used in unusual conditions such as high temperatures or dusty environments, more frequent maintenance checks will be required.

Pump Oil

• Change the pump oil regularly.
• Change the pump oil after the first 50 hours of work and subsequently every 100 hours. Ensure that the oil is changed at least once a year.
• Check with your nearest dealer for advice on the best pump oil to use with this equipment if you are unsure.

Nozzle Tips

If the nozzle becomes clogged with dirt and debris excessive pressure can build up. If the nozzle becomes partially clogged or restricted the pump pressure will fluctuate and can become harmful and dangerous.

Cleaning the Nozzle:

1. Shut off the engine and disconnect the water supply.
2. Pull the trigger on the gun to relieve any water pressure.
3. Disconnect the lance from the gun.
4. Remove the nozzle from the lance, remove any obstructions with the nozzle cleaning tool, and back flush with clean water.
5. Direct the water supply into the spray wand end to back flush loosened particles for 30 seconds.
6. Reassemble the nozzle onto the lance.
7. Reconnect the lance to the gun and turn on the water supply.
8. Start the washer pump and place the lance into the high-pressure setting to test.

Cleaning the Water Filter

• The water filter should be checked regularly and cleaned if necessary.

Cleaning the Water Filter:

1. Remove the filter by grasping the end and removing it from the water inlet on the pump.
2. Clean the filter by flushing it with water on both sides.
3. Re-insert the filter in the water inlet on the pump.

High Pressure Hose

Replace the high-pressure hose if any of the following conditions are present:

1. Cover damaged.
2. Burst.
3. Bubbles/blisters.
4. Kinked/collapsed.

Maintenance Schedule

ALWAYS shut off the water supply, bleed water pressure, and turn off the motor before cleaning, adjusting, or servicing the pressure washer. After servicing, make sure all guards and cover shields are replaced before using.
