How to maintain your Wildfire or SmokeChaser firefighting backpack pump

Applies to:

Wildfire Poly Tank Fire Pump (Model OT4-N) and SmokeChaser Chief Fire Backpack (Model 190790).

What causes this:

Firefighting backpack pumps need routine maintenance after each use so they work reliably in an emergency. Skipping cleaning can let debris or freeze damage disable the pump.

How to fix it:

1. After each use, pump clean water through the system to flush dirt, debris, or fire-retardant residue.
2. Apply a few drops of light oil or grease at the gland nut on the pump shaft to ease operation.
3. Inspect the nozzle for dirt that affects the spray pattern; clean or replace as needed.
4. Check the hose for cracks, swelling, or wear and replace if damaged.
5. Tighten the hose clamps at both the pump and tank ends.
6. Rinse the tank with clean water and check the cap vent valve and gasket, replacing worn parts.
7. For winter storage, add a small amount of automotive permanent anti-freeze to the tank and work the pump several times to coat internal components. Do not use anti-freeze with a leak-stop additive.
8. Store the pump and tank clean and dry, out of direct sunlight, excessive heat, or freezing temperatures.
