Cox Hose Reels – What Maintenance Should I Do?

Avoid Cox Hose Reel Problems with these Real Hose Tips

1. Swivel – The hose reel swivel (on the side of the reel) allows the drum to turn when rolling and unrolling the hose. The swivel contains rubber o-rings that are exposed to heavy use, chemical exposure and temperature extremes. The o-rings will wear out, allowing chemical to leak. The leak starts as a drip but quickly becomes a steady flow.
   1. Standardize swivels on all vehicles for ease of maintenance
   2. Use viton o-rings for longer life
   3. Keep an extra set of swivel o-rings in stock so that repairs can be completed promptly
   4. Ensure technicians know that even small leaks must be reported and repaired immediately.

2. Hose – A few simple tips can extend hose life and reduce chemical spills
   1. When rewinding hose, run the hose through a rag to remove grit, and debris that will reduce hose life
   2. Inspect hose, particularly the first 20 feet for wear and damage. If it looks bad, don’t wait for it to leak, cut it off. This will prevent chemical spills and downtime.
   3. Reversing the hose periodically will even the wear and can extend hose life.

3. Reel Safety- Manual Reel
   1. Inspect the Cox Hose reel lock. Is it there? Is it intact? Does it operate properly, i.e., does the lock fit completely and securely into the receiving hole on the reel disk?
   2. Instruct technicians to check and secure the reel after each stop. Failure to do so can result in the hose unrolling on the road behind the vehicle, leading to equipment damage, downtime, repair expenses and lawsuits.
   3. Our experience is that these reel locks have more problems on trailer sprayers, possibly due to increased bouncing from a rougher ride.

4. Reel Safety – Electric Reels
   1. Electric reels do not have a reel lock. If they did, you would be buying a new reel every time your tech burned out the motor trying to rewind a locked reel. Since there is no lock, it is critical that the spray gun (other other tool) be well secured in the vehicle. If the gun were to bounce out of the truck, there is no brake to prevent the entire hose from winding out behind the truck. This is particularly important for trailer sprayers.
   2. Ensure the hose is evenly wound around the reel drum. If the hose is wound on one side of the reel, it can push the reel off center. This will eventually destroy the drive gear and result in significant repair expense.
