how to repair a bostitch framing nailer

Air tools make the task of learning in the past few years simple.
The frame DingTalk can cut the rough work in the frame from a single room or a small garden shed into a whole house in half.
The Bostitch nail gun, manufactured and sold by hardware giant Stanley, lightens the task for amateur and professional carpenters.
The most common problem with most DingTalk, including Bostitch, is air leakage caused by degraded O-rings and trigger valve seals.
Remove the four mounting screws and fix the exhaust cover to the back of the frame DingTalk, just above the handle.
Remove the screw using the Allen key and turn the screw counter-clockwise.
Lift the lid from the back of the DingTalk.
Pull the piston cylinder from the gun.
It looks like a white plastic tray right behind the nail gun.
If you need to lever up, use a small flat screwdriver, then grab the back of it, pull hard and remove the piston from the chamber.
Check the O-ring for deterioration.
If any O-rings are showing signs of wear, please replace them all.
The O-ring is a round black gasket mounted around the piston cylinder.
Depending on your nail gun model, there will be one or two at the back of the cylinder and one or two at the front.
The kit also comes with a flat rubber gasket suitable for the front of the cylinder.
Also change the washing machine.
Apply a small amount of Bostitch air tool oil to each O-ring and rubber gasket using a cotton swab and install them on a cylinder in the same position as the original.
The placement of different models may vary.
Please consult the maintenance manual for more details.
Re-insert the piston into the back of the tool and reinstall the ventilation cover to wear four mounting screws back to the main body of the DingTalk.
Tighten them with Allen keys.
Use a small metal punch and ball hammer to move the two rolling pins that hold the trigger to the gun.
One is directly behind the trigger, and the second is the last Rolling pin facing the handle directly above the trigger.
Tap the pin onto the other side until the trigger is loose and pull the trigger from the DingTalk.
Leave the pin in the hole for reuse.
Pry open the valve assembly, a green or white plastic tray that is visible at the top of the handle once the trigger is removed.
Pry it out with a small screw knife.
Apply the air tool oil to the O-ring on the replacement valve assembly using a cotton swab.
Slide it into the hole and align the gap on the outer lip with the roll pin.
Knock the rolling pin back into place with a hammer and punch, and work slowly with a tap to avoid bending the pin.
