Since we discussed this in PM wanted to put a reply here for any others who may experience issues. It sounds like the thread tape needs to be removed and reapplied. You'll want to open the release valve on the pump to make sure no pressure is in the line, then close the release valve and disconnect the hose from the cylinder. Verify all the bolts on the bottom cylinder mount are tight. Tilt the press forward in drip tech position, then use a crescent wrench to remove the female coupler on the back of the cylinder. Once the coupler is removed, remove the tread tape on the fitting, and reapply new tape. Finally reinstall the coupler in the back of the cylinder and tighten it completely, connect the hose back up to the cylinder and retest for leaking.
Depending on how much fluid leaked out, you may want to empty the hydraulic fluid from the pump, measure it, then refill with the manufacturers recommended amount.
Also, depending on how much use the pump gets, the oil should be checked once per year and replaced if heavy use in a production environment.
@LongDraw glad you are getting along well with your press! It is a lot of fun, I will be soon pressing some skunk #1 that I have big hopes for! I am glad to see you moving into newer material, you will notice a difference in terpene content and effects =)
