Simplest hydraulic question from newbee

[hondarider]

I have a Fermec/Terrex 650 skip loader with a few leaking hydraulic hose that I'm aware of. I would like to take care of the small problem before it becomes a big problem.

I don't know anything about hydraulics.

So how do I de-pressurize these hose before attempting to remove them?

Any tips on removing them?

THanks!

Just relaxing all the cyl is a good start, by putting the valve handles through full motion, should relieve any pressure. Keep in mind that heat can build in a circuit and build some pressure.

Certain pieces of equipment have a hyd accumulator, that stores fluid under pressure, so just be aware of this. It is used to apply brakes or release brakes, or spin hyd starters, etc.

Use a rag over the fittings when removing. Safety glasses, etc.

Like JJ says...
You will probably find that one end (at least) of the hose has a turnable fitting, the other is attached firmly to the hose. Loosen the turnable one first.

Always use a piece of cardboard when detecting hidden leaks. Placing a piece of cardboard in front of a leak is better than injecting high pressure hyd. oil into yor hand. This has happend and results in serious surgery to remove the oil.

...results in serious surgery to remove the oil.

Good to know. Thanks.

Obvious note: Do what J_J suggested with stopped engine.
