3. Using a shotgun cleaning rod with tip and patch large enough for a
snug fit in the bore, insert the rod and a lightly oiled patch in the
breech end of the barrel and run back and forth through the bore
several times. Remove and wipe the choke tube, threads and barrel
threads with a nylon brush and lightly oil.
4. Inspect the bore from both ends for leading and plastic residue that
often remain in the bores from the shot cups in modern shells. Leading
and plastic residue will appear as longitudinal streaks and are usually
more predominant near the muzzle and just forward of the chamber. A
normal amount of either is common and not serious.
5. If leading or plastic residue seems excessive you can remove it by
brushing the bore with a bronze brush. Soak the brush or spray the bore
with a powder solvent first. Scrub until clean. To prevent bristles from
breaking off, push the brush fully through the barrel each time before
pulling it back through.
MOST SOLVENTS ARE HIGHLY FLAMMABLE. WEAR EYE
PROTECTION AND PRACTICE APPROPRIATE SAFETY
MEASURES WHEN WORKING WITH SOLVENTS TO AVOID
SERIOUS INJURY.
6. After all leading and plastic residues have been removed, run a clean,
dry patch through the bore. Follow this with a final, lightly oiled patch.
7. Reassemble the shotgun and wipe all exposed metal surfaces with an
oiled cloth making sure to wipe away all finger marks where moisture
could accumulate.
8. Inspect the barrel and chamber to be certain no patches have
inadvertently been left in them. Remove any that remain.
9. Lightly oil your firearm at the points described under “Periodic
Lubrication” on page 42. Regular, light oiling is extremely important
to the durability and reliable operation of your shotgun.
Normal maintenance can be accomplished with the barrel still attached to
the receiver (oiling and wiping down). More careful cleaning requires
removal of the barrel from the receiver (cleaning the barrel), and the
removal of the gas piston, piston sleeve and piston sleeve spring
components. A complete cleaning requires removal of the bolt and
trigger group. Do not disassemble the SLP beyond what is shown in
Figure 21 on page 40.
If a malfunction occurs, perform a thorough cleaning to see if it solves the
problem before contacting the FNH USA Service Facility in Arnold, Missouri,
your departmental armorer or a qualified gunsmith.
1. Place the “safety” in the on safe position. Open the action and
inspect the chamber and magazine to make certain they do not
contain any shells. Keep the muzzle pointed in a safe direction.
2. Remove the forearm and barrel as explained under “Disassembly”
on page 36.
