How do you relieve hydraulic pressure on an electric over hydraulic plow?
Permalink  

The plow on my new to me 94 Chev is electric over hydraulic (electric motor powers hydraulic pump). To remove the blade from the mount you need to disconnect the hydraulic lines. There appears to be two quick disconnects. 

I have no idea how to relieve the pressure in the lines or is there any pressure in the lines when the motor is not running?

Any suggestions?

Thanks

If you have quick disconnects it wont matter if you relieve the pressure or not. They are designed to work under full pressure with very little leakage when swapping something out.

There should be a little red button on the control box other than the toggle switches.

You should be able to just pull on the coupler sleeves (sometimes they take a little persuasion, especially if they haven't been removed for a while) and pop them off. They self seal.

I assume these are the quick disconnects?

I'm not sure what these lines are for as there is an electrical harness going into the truck from the other side of the plow. See arrows:

There's no buttons on the controller. Just a joystick that goes left/right (blade angle), forward/backwards (up/down):
