Default 229L lowers really FAST

I read somewhere on this forum that the lowering time is factory set for 12 seconds. Mine lowers in about 4 or 5 seconds. Is there any way to slow this down a bit. It is pretty smooth but is a little scary dropping that fast. Other than that, I have not really experienced any problems going up and down.

Freddie, I believe that the raise time is approximately 12 seconds, not the lowering time. If you think your unit is lowering too fast, just take your finger off of the lowering switch. The top will stop going down at that point. Push the switch again to resume lowering.

I believe there is a valve that regulates that. It's like the valve on a bottle jack. I have never messed with that so I don't know for sure.

Default lowering problem

Rich is correct. On my pump there is an adjuctment that controls how fast the top lowers. Since HiLo used different pumps thru the years I can't say about yours. If I remember correctly that adjuctment is in the owners manual. If you can't find it get back here and I will look it up. On my pump there is an adjuctment to set the pump output pressure. Don't change this control as you can over pressure the hydraulic system.

Thanks for the link to the manual. I saved it on my computer and am going to print it out out and read over it tonight. This is great to have for my file folder on my camper. Am sure it will answer a lot more of my questions in the future.

The valve mentioned on the motor is for manual lowering only to my knowledge. The switch itself is actually wired up to solenoid that controls a gate. That gate is what controls the lowering when using the lowering toggle switch. The manual valve has to be tightened down all the way at all times or it will bypass that gate. I'm not sure of all the hydraulic plumbing though and how that actually works. If you are having issues with it being to fast the factory hydraulic plumbing may have been replaced on the output side. I could see this being the case if they used a larger diameter pipe allowing the fluid to dump to fast back into the reservoir. If I let mine drop as fast as it wants to, the reservoir overflows for some reason. i could be wrong in regards to your actual setup but thats how it is on my 1998 model. Mine was completely gutted when I got it. It didn't have a single wire going to the motor and the entire control panel was gone. Thats been about a year ago, but at that time I was very familiar with how it all worked. I had to rewire the entire thing, and a lot more goes on up there that most realize. It was not fun trying to figure it out.
