For the elbows where the nozzles are mounted, those are all supposed to be set to an angle of about 30 degrees in the same direction. As that manifold is supposed to be free spinning, it's rotated by the inertia generated from the angle of the nozzles. If someone has straightened them so they...
At the MAC panel on the right side of the machine, turn off the air going to the machine, then dump the residual air from the system. Does the TB drop? It should drop completely. If not, I'd suspect you have either a bind in the bearings, or something catching on the counterweight to prevent...
I don't know what vintage machine you have, but if it's one with an FX3U PLC and there are arming options for a "onboard drive thru dry" that can be added to each individual package. If it's intermittent, does it follow a specific wash package? If so, just turn off that arming bit for that...
It sounds like your tire photoeye PLC input X20 isn't transitioning properly.
In the brush sequences, as the machine travels reverse, it's monitoring that set of photoeyes so it will decelerate properly when they detect the rear tires and slow the machine down while it washes around the rear of...
If you go with on-board dry, and you have 30'-6" free and clear space, a Softgloss MAXX would be able to wash up to an 18'-6" long vehicle completely (top brush coming off the back of an SUV). Slightly longer on sedans.
You should be able to wash longer vehicles with a 5 brush as the machine...
I replaced my Genie about 5 years ago and put in a Liftmaster. Not sure model, but it's belt drive and similar to the 8550WLB they have today. It's been reliable for me so far, and I do like the battery backup. The batteries don't seem to last more than 2 years, but it's helpful when the...
On the older machines, the clutched portion was the upper half to help prevent grabbing antennas or mirrors. For the lower portion, I agree with the comments above where it's most likely tangling into a rear trailer hitch or similar. You may want to ensure the rear arms are level though as if...
If your emitter and receivers are mounted on different height stands, make sure the receiver is the one mounted high and angled down towards the emitter. Many sites have the receiver looking "up", and the sunlight will affect those.
If you remove the polytube from the top of the blue-white pump, put your finger over the top and run it using the manual switch. If both check valves (inlet and outlet) are good, you won't be able to hold back the pressure. If either is bad or needs cleaned, you will be able to hold it back...
Use a small flat blade screwdriver (1/8" or less) into the square hole below where the wire is. It should insert about 3/8" or so. Slightly tip your screwdriver away from the wire, and it should release.
There are still a handful of those around, as well as the even older Model 4 and 5. Those were before my time, but I believe there were actually 4 versions of the R784. Those models often had saddle tank for detergent/wax, and they had the electrical and pneumatic panels on the same side and...
I agree with Slash. It could also be the needle valve on the TB air cylinder used to soften the lift so it doesn't have hard contact when it raises. If that needle valve setting has moved, it could be set too restrictive.
Any coinbox with relay arming can work with a Softgloss. It really depends on what vintage of machine you have for the steps you will need to take. If you can send me a PM with your serial number and program/rev inside the PLC, I can send you the info you will need to make the transition.
If you replaced your VFD, did you program it? When you manually drive the machine, are you using the enable switch? If it's just not changing directions, I'd suspect that relay K3 may not be functioning correctly as this controls direction. If you didn't program the new VFD, and if the relay...
