It is important to keep your hydraulic hoses clean so that they are kept in good working order, the same goes for your connections. Also in cleaning the hose it allows you to inspect the hose for any signs of wear and tear that may have occurred and that could potentially cause a failure of the hose when under pressure.
As always with anything electric turn off the power then start to get to work cleaning it. Then after you have done that start to make up a bucket full of soapy water much like a normal washing up solution or you can put hot water with specialised pipe cleaning solution if you have some at hand.
Dip a cloth into the bucket and use it to wash down the hoses, make sure to remove all of the accumulated dirt, oil and grease as best as you can you may have to swap cloths and repeat a few times depending on how old the hose is. Be careful because the pressure is still in the system and could be potentially dangerous. Make sure that you clean the hose thoroughly and especially clean the fitting into which the hose is housed because this will board well when getting a new replacement and will work better.
After you have done that make sure that the connections are all tight and intact. Then inspect the hose for any damage or abrasions, try to look at the hose as much as you can as there might be a start of a break and then if you do find something replace it accordingly. In the unfortunate event that you may find something wrong then you need to remember never to disconnect any hydraulic hose until you release the pressure out of the system.
After you have checked that everything is secure, in working order and not going to break down anytime soon then you can start to rise the hose this just makes It that bit cleaner before you start to use it again.
