2.- Follow the decompression procedure
explained on page 1.

at the rear (outside the gun body) are horizontal.
9.- Assemble the piston-cover, insert in the
horizontal planes of the needle.
10.- Tighten the rear nut with the female tube
accessory wrench.
11.- Place the diffuser head and tighten this
