The last screw holding the 2 halves of the drill is located underneath the handle grip (see image). Carefully remove handle grip. (see image)

Disconnect black and red wires off of the motor. (see image)

Replace it with new trigger either by soldering or using electrical tape. (trigger replaced using electrical tape)

Screwdriver, Adjustable wrench, Ratchet wrench and sockets (sizes differ per model), Teflon Tape

Turn OFF and unplug the compressor.

Remove motor shroud. (see image)

Disconnect high pressure tube from the cylinder head using adjustable wrench. (see image)

Use ratchet wrench and socket (sizes vary) and remove head bolts. (see image)

Locate valve plate (it's located in between the cylinder head and cylinder approx. 1/8" thick. (see image)

Remove 2 Phillips-head set screws. (see image)

Re-install everything back together using Teflon tape specifically when connecting high pressure tube back together onto the cylinder head.

Reassemble your unit in the reverse order. To avoid an air leak, use Teflon tape when connecting the high pressure back to the cylinder head.

Plug the compressor back in and turn ON, check for leaks.

Let the compressor build air to its maximum pressure. Leave switch to the AUTO/ON position, it should automatically turn OFF once it reaches the max pressure (approx. 90-115 PSI).

Relieve some of the air from the tank (either by draining it using a drain valve located either on the bottom of the tank or on the manifold or by using an air tool). The compressor should automatically turn back on once it reaches cut-in pressure.

Tip: You may have dirty water release when you relieve the air from the tank. Use a bowl on top of a large piece of cardboard or towel to collect the water and protect your floor.
