I have a CH HJ 300200 that will not build pressure, there seems to be pressure building in the tank but the Pressure gauge does not move. I removed the pressure line going to the tank, it gets hot and...


Bill:

I would remove the pressure gauge and check the bottom of the air gauge fitting. The small hole at the bottom of the gauge fitting may be clogged. Sometimes when the pressure gauge is installed a piece of Teflon tape (used to seal the threads) can get lodged over the pressure gauge air port.

Why wont my steelcraft 13 gallon 5hp model ta25 build up no more then 20 pound of pressure and all i did was change the oil?


Check all connections for air leak including the water drain valve with soapy water. If no air leaking from connections, spray soapy water on head area where head attaches to the cylinder checking for gasket leaks. If no leaks are found, most likely problem is in the head /valves /internal gasket leak. If head gasket or valves are leaking, you will notice that air seems to blow out of the intake filter (normally there is good suction at the intake). Good luck

You can unscrew it without removing the plastic part - just use thin vice grips and get a piece of the metal nut, unscrew down (counter clockwise) and it should come off with average pressure. I checked mine, not much to go wrong there, then screwed back in. I have similar problem with pressure, it is likely a worn O ring. Seems to be in the outlet valve as I replaced some of the inlet valve rings and same effect. Research says the outlet valve is the problem if paint comes out of the squeezed nozzel while in Prime mode, which mine does, and is likely not building the pressure as some paint is flowing back through the worn outlet parts.

Husky comp on 1st start builds up 75 lbs and wont restart


Check the reset button on the motor to see if it tripped. The motor may be overheating. Some motors have an internal breaker and they have to cool off before they restart. Also check the pressure switch. Move the switch back and forth ( on and off ) and listen for a click. If it doesn't click with low to no air pressure then the switch is bad.

WILL NOT BUILD PRESSURE


Many craftsman compressor are built by champbell hausfeld using a dry type of cylinder and piston (no oil, no crankcase). If dry type, check for worn cylinder and piston ring. Pieces of the vinyl ring can jamb between the reed valves in the head causing air to escape from the intake. If your compressor has a crankcase and oil, check for broken reed valves in head. Spray soap solution on hoses, checkvalve, drainvalve, and fittings to check for leaks. Most likely problem is reed valves broken or open. Parts are available from sears or match parts to chpower.com. enjoy
