Easy oil fill, dosen't matter if you fill through the oil fill or exhaust port. Requires a 10-30 second break in period prior to first use... Anytime you remove the oil fill cap, always inspect the o-ring as mine fell off the cap and luckily I happened to notice. Also, double check drain plug prior to first oil filling out of box as mine seeped a little oil, don't over tighten, just snug as you may potentially damage o-ring... The pump comes with a hex drain bolt unlike a knurled bolt shown in image...
Pump will pull a vacuum within 20 -30 minutes on a/c auto systems. After 30 minutes of operation, the unit is safe to touch ( lukewarm ). I was initially concerned with the plastic handle but it has a solid, sturdy feel. The pump will occasionally mist oil out the exhaust port, more so at vacuum start up or if overfilled. As for oil usage, I performed 5 30 minute vacuums w/o any noticeable oil loss. As for loudness, it relatively quiet and safe for indoor use, minus occasional oil mist...
I've only pulled a vacuum on five auto 134a a/c systems since purchasing, 3 of these jobs were compressor burnout replacements while the other 2 were refrigerant loss / leak repairs and the oil has just now shown signs of needing to be replaced. I know every manufacturer recommends you change the oil after every use, they also recommend you use only thier brand oil.
As I was saying, during the 5th vacuum I pulled I noted the oil was getting milky during vacuum operation upon visual inspection through the sight glass, although the oil was clear after shutdown. Time to change the oil as that is where all the moisture remains that doesn't get boiled off during vacuum, while the frequency of oil change intervals is debatable.... the oil will need to be changed when showing signs of cloudiness in color, poor performance or you can routinely change after every use as recommended should that be the maintenance interval you prefer, no doubt the pump will pull a quicker vacuum with fresh oil.. The pump comes with a bottle of oil that is enough for 1 1/2 fill ups....
Hint: Buy a pump oil that contains no additives, as additives breakdown and contaminate quicker when mixed with moisture.
Also, ensure that you install the dust cap on the pumps fitting while not in use to keep moisture out as failure to do so will shorten the oil life span
One thing I've noticed is this pump pulls a vacuum pretty quick for its size, you can hear the change in the pump when the pump has pulled most of hte moisture out of the system. On the 3 a/c systems where I replaced the receiver driers and compressors, the pump pulled a vacuum down to 29 µm and 28 µm on the systems w/o drier / compressor replacement.
See pics below of vacuum in progress, oil fill port, sight glass and drain plug.....
I would have loved to have bought a higher end pump but funds were tight. None the less, I am very satisfied with my purchase, very smooth transaction...The only shortcoming I found.... Made in China
Update: Performed 17 auto a/c vacuums since purchase, no complaints ....
