When you buy an air hose reel, you will realize that maintenance is very important. Once you buy one, you need to have the manual with you to familiarize yourself with the parts and how to use it, replace and store. In this article, we are going to look at various aspects of the retractable air hose reel maintenance.
Parts of the air hose reel
The best start is to know the parts. They include:
- Outlet hose
- Hose stopper
- Hose guide bracket
- Guide arms
The recoil tension
This will need to be adjusted. To achieve this, you have first to close the air supply from the valve that allows in air. This is known as the air inlet valve.
The hose reel is pulled out a few feet so as to lock the reel spool. This is important as you will prevent it from retracting. Sometimes you need to increase the tension. This time round, you need the unlatch the spool. This is done in anti-clockwise direction. The clockwise latching is for decreasing tension. Having this information is important ad especially for the first time owners of the air hose reel.
The reel has a part that we call the O-ring. It sometimes gets damaged due to wear and tear. Once again, you will need to turn off the air supply at the air inlet valve as above. The O-ring is opened and removed so that a new one is installed.
Re-assembling should be easy for you as all you need is to do the reverse of the above.
The hose replacement
The hose, just like other parts of this equipment, gets damaged. To start off, you need to secure and stabilize your reel. This should be followed by the disconnection of the air supply.
After stretching out the entire hose, the spool is locked in place.
There is hose clamp which holds the reel in place. This is the one that you should unscrew. Two other parts you will come across is the inlet –end of the spool as well as the bracket rollers. The hose reel should come through this inlet that lies in between them. Once you are done, the hose reel will come off easily. You can now go for the other parts to be removed. In this case, the guard spring, hose clamp and stopper. Since all these parts are still in pristine condition, you do not have to throw them away; simply fit them inside a new hose reel.
The next bit would now be to direct the inlet through the guide brackets of the spool. Before connecting the air outlet valve to the hose connector, it is advisable to apply a sealing tape or sealant.
Lastly, the hose clamp is attached back to the spool of the air hose reel and the whole equipment will be ready for use the normal way.
Replacing a broken spring
This could give a headache to replace unless you have a manual or has handled a similar problem before. The first 3 steps are basically the same as those of adjusting the recoil spring. The locking cam should be unlatched in a gradual manner; otherwise the unwinding process might be messy… This should happen slowly so that there is release of tension and at the same time the spool comes to a halt.
There have been cases where injuries and damage have occurred when unlatching the locking cam was done rather quickly.
The hose reel should be removed from the mounting location in a safer way. The hose reel is placed on a flat surface but ensure that the air inlet is facing downwards.
The guide arm and the support leg are the nest parts which should be removed, save for inlet parts. The main spring hub is the next out followed by the nuts, pull spring cover and finally, the worn out spring is fished out.
The new main spring is now ready to be installed. You should ensure that the correct position is used such that there is engagement with hook.
Once greased, the parts are returned in place through reverse process.
