Has anyone else had an issue with gas "flying" out of can when opening after carrying it? It seems to pressurize, and when you pull on handle, look ou

Set the can on the ground and slowly open the valve to release pressure. Then Use

Just like any gas can, you should not fill it all the way to the top if you plan to store it in a place where the temp changes frequently. I noticed an odor with mine when I first got them because I had done this. Some of the fuel had permeated the seals and there was a strong odor coming from the cans. I corrected this issue by leaving some room at the top of the can for expansion due to changes in temperature. Also, be careful if the cans are completely full and you open them! Gas will spew out once the seal is broken on the full can if the temperature is higher than when you filled the can! Also, if you fill the can when it is very warm outside and put them away for storage in a cool place, the can will contract a little but return to original shape and volume once the pressure equalizes with the outside temperature.

I encountered this problem and while reading the manual I found that fresh gas must be used for proper operation. I replaced the gas and it performed well.

I have had a the same thing happen, only mine didn't happen until several months after use. I'm not sure if this is the right thing to do, but I just "pop" it down with my hand kind of hard and it starts. As Scott said, it started doing that after I didn't get it sealed and it leaked. So I am guessing that there is just some "gunk" in there causing it to stick. If you wouldn't mind, please post what you find out from customer service. I am still able to use mine, but it continues to stick occasionally.

Mine never worked well. It always had to go around 2 or 3 times to open a can. Working at all, it lasted about 3 months. I purchased mine in mid may, it is now mid august. I'm here on amazon looking for a replacement because it barely opens cans anymore.

The first time I used the Mastrad it distorted the seal & gas escaped. I discovered that I hadn't screwed the cap on all the way. The seal should not be visible when it is tightened & actually continues to rotate 1-2 more times before it is truly sealed. Then before i put the cartridge on I press the release valve in go make sure it is not stuck. Make sure not to cross thread the cartridge holder. After gassing I leave the cartridge in place, shake the canister & put it in the fridge for several hours. When ready don't try to open it until you press the pressure release valve until no more gas escapes. Then open the lid & replace it with the storage cap. If this doesn't help then I suggest you contact Mastrad. Oh yeah, use the white funnel provided to fill & only fill until the liquid touches the bottom of the funnel.

mines still in a shed from October so I haven't seen it in a while, but I had a problem too theres a choke and a fuel switch, play around with the fule switch. I think mine was backwards maybe or something

That was a symptom I had when there were either air bubbles in the system or an obstruction somewhere. Eventually the valve, or whatever the mechanism was internally, froze in place and it wouldn't generate pressure at all, despite clean system. That's when I returned it to Costco, only a year old. Went with a more expensive gasoline unit instead, much better power for cleaning and longevity.

In my case excessive vacuum inside the bottle has been the culprit. If you notice the walls of the bottle collapsing in on itself, the pump of the sprayer may not be able to refill itself before the next trigger pull. Usually happens when the fluid level within the bottle is low. Just pull the bottle back out and loosen the cap to vent air back inside (tighten cap before reinserting).

Is yours leaking any fluids by chance? Mine started to shoot just puffs of air 90% of the time and I noticed that it had oil / grease leaking from the black plastic bit just above where the connection is on the gun. Only used it 2x, no jams, never used higher than 100 psi etc. In the process of sending it back and getting a porter-cable.

Am so sorry I cannot answer your question. I bought this as a gift for my son. Guessing you have kind of a vapor lock. Maybe put a very thin knife in and try to release the pressure that has built up. Know I need to do that when I open goods I have canned. Good luck.

Make sure the lighter is upside down and hold it firm. Make sure u insert can direct down not sideways and push it down and hold it for about 3 second bursts about 5 times. Mine works amazing. Some times if it's not upside down a and straight and can tilts it can happen. Push can down firm. I only use premium fuel cans

where is the leak in the bottom cap , if so check to see if the gasket is there. and also see if its not ripped/ torn anywheres along the edges . if it the little plunger make sure there is no scale build up on it that might keep it open when you turn the reservoir back over when you carry it . other wise it may have a crack some place .

You are probably filling it too tight, I have noticed when I do, the handle gets very hard to push-pull. I have only had to clean out mine once, cause of this and try not to fill it too tight. Try this and see if it works better for you. Also after every use I lift a corner of the mat and empty the dust and particles that collect there.

I would have to agree, it sounds like the gasket isn't sealing properly. Just be sure there is no obstruction in either the lid vent or the vent hole of the weight. Mine has worked very well with no problems for a while now. Sounds like the seal isn't quite aligning.

hi Sangki,Iv'e had my pan for several months. The handle still seems tight as it should. If yours is loose Iwould exchange it for a new one. To be honest with you its a great pan, cleans easily. Iwould buy another. I think it' the best. thanks jimmy

Did you put the fine film of oil on the lid? I originally missed that on my AA. I have only gotten a slight steam leak once or twice, but it seemed to stop when I got up to pressure. Sorry I can't help more.
