The issue suggests that the head gasket is blown between the two cylinders or the reed valves are not seating or broken. The only other condition that would cause this is a leak. Here are a couple of simple tests. For leak spray soapy water on all connections and fittngs including the pressure regulator and the bottom of the pressure switch while unit is running. Repair as needed. If no leak is found, run compressor untill it reaches 60 or stops increasing and feel for suction at the air filter intake. The best way to check for suction is to remove the air filter and feel for suction at intake port-hole. The suction should be very strong. When valves are leaking it almost feels that the air is blowing out thru intake. If little or no suction, remove head and valveplate and replace parts as needed. Parts are available at www.chpower.com or www.toolpartsdirect.com. Good luck and post again if you have other question.

First take off the head on the air pump and check the reed valves on the valve plate. If they got hot and warped or cracked they'll work to a point then no more pressure can be built up. Next check the pistion ring and cylinder wall. If either is damaged you'll only get so much pressure build-up then it will leak past the piston.

I'd pull the cover off to expose top of cylinder head and have a look at any intake air filter. In parts diagram, It appears there is a small one that would likely clog during the texturing process.

Something may be wrong with the 'unloader' function in the air pressure control--it should drain air pressure within the exhaust tube from the compressor. You may also be running the unit on too small wiring (extension cord) and it is starving for power when the heavy load restart occurs. Hope this helps!

WILL NOT BUILD UP AIR PRESSURE PAST 20 LBS.


Check to see if air is leaking past 'pressure relief' valve. It's probably leaking and that's where all the air is going.

Tank will not build pressure beyond 25 lbs. Just runs


IS YOUR AIR FILTER CLOGGED. SOUNDS LIKE THE VALVES IN YOUR HEAD ARE NOT CLOSING ALL THE WAY. THEY ARE MOST LIKELY REED VALVES, THIN STRIPS OF METAL THAT OPEN AND CLOSE WHEN THE PISTON MOVES. MAKE SURE THEY ARE CLOSING ALL THE WAY (NOT CARBONED UP). DID YOU REMOVE THE HEAD AND DID YOU PUT BACK LIKE YOU FOUND IT - NOT TURNED OR FLIPPED OVER. SEE IF YOUR FINGER WILL GET SUCKED UP TO THE INTAKE HOLE.
