CHAPTER 8 : MAINTENANCE Before any intervention on the P90® submachine gun, ensure to be fa miliar with the safety information given in chapter 4 of this Maintenance Manual.
The frequency at which the P90® su bmachine gun should be cleaned and lubricated depends on the ammunition used, the weather and shooting conditions and other external factors. When using normal ammunition under normal conditions, it is a good rule to clean and lubricate the submachine gun after every use or, in case of inten sive shooting, after each 2000 rounds : correct maintena nce will enhance the longevity of the gun.
NOTE : When using subsonic ammunition, which results in a much quicker soiling of a weapon, the cleaning frequency should be conside rably increased : the condition of the submach ine gun should be followed up all along the shooting seq uence.
Before cleaning the P90® submachine gun, ALWAYS ensure that it is unloaded (refer to§ 6.4).

CLEANING AND LUBRICATION BEFORE FIRING The following procedure assumes thot the P9Q®submochine gun has correctly been cleaned and lubricated the lost time it has been used (also refer to§ 8.3). If the P9Q® submochine gun is used for the first time upon purchase, it is assumed that the procedure described in chapter 5 hos been carried out. • Carry out the field stripping procedure (refer to chapte r 7). •
Using the cleaning tools OREA 85 1 and clean rags (pieces of flannel), remove the maintenance lubricant from the inside of the barrel (131) until the lost rag is clean .
•
Dry the inside of the barrel ( 13 1).
• Rem ove the maintenance lubricant from the moving parts group [ 3]. • Slightly lubricate the moving parts group [ 3 ] by proceeding as follows : - Apply 2 drops of functional lubricant to each breech block assembly guide rod (C2), just behind the breech block assembly (4 20) . - Move the breech block assembly (420) at least three times back and forth. Apply 1 drop of f unctional lu bri ca nt to the ejector (443), to the extractor (435) and to the ho les of the breech block assembly (420).
The other ports of the submochine gun do not require lubrication. • Reassemble the gu n.
The P90® submochine gun o nly requires minimal lubrication. Excessive lubrication of the weapon or the presence of a lubricant inside the magazine [ 5 ] will have on unfavourable effect on the rel iabil ity of the weapon and the longevity of its parts.
Before each shooting sequence, A LWAYS check the barrel ( 131) for obstructions and ensure that it is dry and clean.

Reassembly
If it is necessary to handle the tritium light source (714), the normal radiation hazard procedu res should be carried out. Also ensure to be fami liar with the safety information especially applying to the tritium lig ht source (7 14) (refer to § 4.3) .
• If the tritium light source (7 14) has been removed, re install a new one by proceeding as follows: - Insert the tritium light source (714), with its painted side facing upwards, into its opening in the optical sight body (A2). - Seal the opening with the tritiu m light source (71 4) by using silicone rubber 3145 RV - After having applied the silicone rubber, gently push the tritium light source (714) against the light wedge of the optical sight. This ensures that there will only be o thin foyer of silicone rubber between the tritium light source (7 14) and the light wedge. - In o dark place, check the open lill umination of the optical sight.
If necessary, and as long os the silicone rubber has not hardened, gently change the position of the tritium light source (714) in order to optimize the open T-illuminotion of the optical sight. Let the silicone rubber harden for at least 48 hou rs. •
If the 2 sig ht adjustment screws (715) have been removed, screw them bock into position by using th e sight ad justm ent spanner OREA 849 (Fig. 9. 1.1).
If the some sight is used again and small marks have been mode, use these marks to ensure that the screws ore screwed bock into their original position. •
If the optical sight (7 11) has been removed from the barrel support body (1 2 1), fit it back into position and then fix it with the 2 hexagonal socket head screws (712) (fig. 9.1.m).
Use the hexagonal wrench OREA 8498 to correctly secure the 2 hexagonal socket head screws (712).
