Question about Craftsman Air Tools & Compressors

1 Answer

Craftsman spray gun (919155190) tip is leaking fluid when trigger is NOT depressed. This happens at 8psi as well as 40psi. If I turn the fluid control knob "off", then there is no leak. If it is even a little "on", there is plenty of leak. Help!

The tip as well as the pressure, are regulated in part be the viscosity and consistency of the product being sprayed. If the orifice is clogged, then it will not shut off properly and will cause splotchy spray when turned back on.

If the mixture is not smooth, the lighter part will leak out while the heavier parts remain behind... This of a lumpy gravy, the lumps hold the orifice valve open while the gravy leaks out.

Remix your solution, and pay attention to the viscosity requirements for your tip.

Good luck and don't forget to vote.

Bostitch just blows air when trigger is pulled


Air leaking from trigger when attempting to fire the gun is normal and should cause nailer to fire, however if the trigger pin is not depressed all the way in,the gun may not respond. Easy test. Remove the nails and remove the trigger. Connect the gun to air and quickly depress the valve pin all the way in with finger. If the gun fires, adjust the safety foot so that the trigger pin is depressed all the way in. If the gun still does not fire, then remove the head cap and pull out the headvalve. Apply plenty of white grease to orings and retest. If the gun fires, then replace the headvalve orings. When the headvalve orings are worn, air will leak from bulkhead chamber to the headvalve chamber causing the gun to not respond to the trigger. The addition of grease to worn orings will make them temporarily seal. Good luck

How to repair of air leaks out in the plug in of hand held air tools when i depressed the trigger


This problem occurs when the orings in the headvalve and/or trigger valve are worn or just needs lubrication. This also happens when the safety foot does not push the trigger valve all the way in. Easy test. Remove nails and air pressure. Remove the trigger exposing the firing pin on the trigger valve. Connect air and with a very quick motion, depress the firing pin all the way in. If the gun fires adjust the safety foot. If the gun does not fire, remove the head and pull out the head valve. Lube orings in head with plenty of white grease. Reinstall head and test. If the gun fires, time for oring kit or just keep applying grease. If the gun still does not fire, most likely problem is trigger valve orings. Good luck

I have the 2 1/2 Hitachi for nailing siding. The nail gun had not been used for a couple of years, but now will only drive the nail half way in. Sounds like an air leak when driving the nail. I have...


Remove the nails and air supply. With side door open notice position of driver. Driver should be at top position with tip not visible. If driver is down and it moves within cylinder when you tilt nose up then down again, time to replace orings. If driver is down, it should extend past the nose about 1/4 inch (if driver is broken at the tip the end will look rough and nail will not drive in all the way). If driver extends past the nose more than 1/4 inch then lower bumper may be breaking up /cracked. Easy test for proper function. With nails removed and side door open, connect air to gun and dry fire gun against hard rubber or old coiled air-hose (with air connected and trigger depressed, no air should leak from trigger area, if air leaks when trigger is depressed, look for fault at trigger pin). Feeder should move back then forward in quick motion almost matching speed of driver and driver should not creep down between shots. No air should leak from nose of the gun (push nose against hard rubber and depress trigger and hold in this position, driver should stay down with very little or no air leaking out of nose, when you release trigger, driver will return). If air leaks out of nose while holding in this position, replace lower bumper. If a quantity of air leaks from valve in front of trigger, cylinder orings may need replacing or outer part of cylinder has fine scratches (remove scratches with 400 grit paper). Parts are available at www.toolpartsdirect.com. Good lucki

GX 08 spray gun problem


drain your system of pressure. remove your air cap and nozzle from the gun. slowly increase fluid pressure till it comes out of gun. this will clean out debri from gun. reduce pressure so you don't wast anymore fluid.
clean nozzle properly / completely
clean aircap. properly / completely
inspect needle tip for abnormal wear.
if cleaned properly you will find your gun works much better.

Spray guns


hey do not see any answers so here you go -First I am not an apprentice on this matter- I spray cars as a hobbie- controls can be determined this way-follow these steps look at the trigger typically the needle that is lowest on the handle will be the air -top most will be paint.Paint will be adjusted by feel- the air is easy to adjust-back the knob off all the way- hold trigger on fully depressed(without being hooked to air) turn knob until you feel it touch trigger-stop- this is now adjusted.

I do recommend you lose the syphon system -gravity will sevre you better- you will use less paint and it is better for enviroment.

Go to web site for new book- best of luck -I will watch for you- what are you trying to paint?
