Before installing the quick coupler and gauge, wrap 1-2 turns of packing tape around the threaded connections to prevent air leakage

  • This oil-free vacuum pump has a mechanism in place to avoid overloads. A machine that works continuously for a long time could automatically switch off due to a high internal temperature. Before restarting the motor, allow it to cool for 15 minutes.

  • 1: the machine is not positioned correctly. Solution: Firmly cushion the machine's four legs;

    2: The crank's fixing screw is unsecured. Solution: Tighten the crank's screw.

  • 1: There is an air leak at the machine's air circuit connection. Solution: Tighten the air circuit's connecting pipes.

    2: Excessive wear on the piston ring or cylinder. Solution: Replacement of the ring or cylinder on the piston.

  • When installing the vacuum gauge and quick-adaptor, the complimentary raw material tape should be wrapped around it before installing it in order to provide a complete sealing effect so that the pressure can reach -85kpa.

There was so much included in this kit. I really appreciate all the extra parts, the Gage is very easy to read and not ambiguous at all. The pump itself doesn't make a whole lot of noise and so I don't have any issues running it in my garage while doing work on parts, I found it really easy to hook up to and doesn't seem to generate a lot of heat. Overall it has very strong build to it seems durable and I don't expect this thing to blow out Anytime soon,does exactly as I expected to and I'm happy with that.

I hadn't had a chance to use this from the time that I got it but I finally got to use it just doing some experiments at home and it worked fine I had no trouble doing my little experiment. At first I had trouble hooking it up and getting it to work but once I figured everything out read the manual it worked great. The machine is definitely built with the little quality and doesn't make that much noise I mean there's noise but it's not irritating are super loud

I got this for our workshop as we're planning on getting into resin work. From the small tests we ran, this works great. I used a chamber I bought off Amazon, the vacuum pump is a bit loud, but only as it reaches max negative pressure.

This is a quite little pump - smaller than I would have guessed - It's very light weight and portable.There is some assembly required - adding the muffler to the output side and a hose fitting to the inlet - then adding the pressure gauge to the last port.Several sizes of hose fitting are included as well as a roll of teflon tape for sealing the threads - assembly took about five minutes.The pump noise is quite low - surprisingly low to me - the muffler works well to deaden the air flow out of the pump and once a hose is connected to something on the inlet, that side quiets down nicely.Motor is running smoothly and very little vibration - it stayed where set.The power cable is fairly short and is spliced to the motor wiring - its safe but not very protected - there's no significant strain relief and it could be damaged - or pull on the wires inside the motor - so I added a cable tie to hold it to the motor along the bolt at the bottom.The in line switch works fine and is convenient.There is a small "don't touch" sticker on the side of the motor - the motor and pump heads do get hot with use - too hot to touch comfortably - Which does mean that the pump needs to cool off before being picked up or moved (no protected handle) but it takes a while to heat up and cools down reasonably quickly - hasn't been a big issue.Oilless design means that the pump can be stored in any position and won't leak oil or have the oil contaminated by use.Overall, I think this is a nice little pump - maybe short on features but effective and quiet - for small jobs and intermittent use, its a nice option -

This is an open frame vacuum pump that feels a bit sketchy, with a capacitor zip-tied to the outside, and the lead wiring lacking any strain relief and lacking a proper vinyl or sjo cover over the leads from the unit to the AC supply store, being covered with a single layer of shrink to fit tubing.The pump does work, but came with a single page printed sheet of instructions with no images. I had to look at the listing photos to see what was supposed to attach where. The vacuum gauge is damaged beyond use and I've had to buy a replacement.The quick connect fittings are clever and work with stiff plastic tubing - I've not seen them before but they are easier to use than barbed fittings.It's noisy, but not ear damage noise levels. The muffler makes a slight difference.

This is a great value for a complete pump with a variety of quick-connect adapters. I initially received a buggy unit, but the seller sent a working replacement in days. Satisfied and grateful!

Product arrived fast and as described. I had no trouble setting it up for use. The vacuum is quieter than expected. Seems like it was made with quality materials because I have used this a few times and it is still running great. Good value for the money. I have tried a couple other oil-less diaphragm pumps off of amazon, including the expensive ones.. I think this beats those.
