Even though power and water are disconnected there may be pressurized water in the hose. Discharge this pressure by pulling the trigger on the gun in a safe direction.
Make sure your work area is clean and appropriate for the work you are about to do. There will usually be a small amount of water inside the pump and hose.

1. Old or new hose setup?
To determine whether you have a new (swivel kit) or old swivel connector, you must first unwind the hose to see the swivel assembly:
Pull the hose completely until the entire hose is out of the reel, allowing you to see the swivel connector.
A) The new setup includes a separate hose, brass female quick connector, and male quick connector.
B) The old setup has a female square head quick connector in galvanized steel connected to the hose.
If you have this setup and need to replace the swivel, the hose will also need to be replaced. The new hose comes with a female coupling; please refer to the instructions here for removal. Then you end up with setup A/new swivel kit.
Note! New swivel kits are complete with swivel, square head quick connector, and C-clip.
2. Remove reel wheel hose cover (d)
A) New reel: Use a T25 to unscrew 4 screws.
B) Old reel: Use a T25 to unscrew 2 screws.
3. Disconnect hose with new swivel
a) Push in the quick connector spring.
b) While pressing the quick connector spring, pull the hose out simultaneously.
C-D in Step 4 can be applied to a new machine if disassembling the swivel proves challenging.
4. Disconnect the hose with old swivel
a) Carefully use a flat screwdriver or special tool to loosen the C-Clip.
b) Pull the hose end off the swivel. An O-ring in the swivel may make it difficult to remove the hose end. In that case, do the following:
c) Place a wrench approximately size 21 or similar on the back of the swivel.
d) Tap on the wrench with a hammer or similar until the swivel loosens. The swivel must be as straight as possible to the swivel's axial direction. Check that the swivel hasn't been bent after the hose is disconnected.
Steps c-d can also be applied to a new machine if disassembling the swivel proves challenging.
5. Install the quick connector kit
a) Put the quick connector, onto the hose reel swivel. If the hose swivel is difficult to fit into place, use the wrench on the outside of the swivel and gently tap with a hammer until the hose swivel is in place. The hose swivel is in place when the groove for the E-clip is visible on the outside. If possible, apply a thin layer of acid-free Vaseline or equivalent to the swivel O-rings.
b) Secure the hose swivel by installing the E-clip into the groove.
NB. Inspect the O-rings before assembly, if they are visibly damaged, they must be replaced. You will find 2 O-rings in AVA First Aid Kit
6. Install new quick connector hose
a) Push the hose end into the quick connector until it clicks in place.
b) If it is too hard to push, you can deactivate the locking system by pushing in the quick connector spring. If possible, apply a thin layer of acid-free Vaseline or equivalent to the quick connector O-ring.
