							Lubrication and Maintenance 
WARNING:Look into the ejection port and check the chamber and the magazine to make sure there
are no shells in the firearm before cleaning or storing. 
CLEANING 
The amount of shooting between cleaning will vary greatly depending on climate, weather conditions, ammunition
used and the amount of lubrication.
The Model 11-87™ Autoloading Shotgun and Model 1100™ Autoloading Shotgun are gas-operated firearms.
Gas operation provides significant recoil reduction by bleeding gases off the barrel to pressurize a piston
which unlocks and functions the action. These gases carry combustion residues which can foul the magazine
tube and/or piston/piston seal assembly, particularly when the firearm is subjected to: cold damp conditions,
over-lubrication or use with ammunition that is not clean-burning.
TO CLEAN THE BARREL:
1. Use the instructions and equipment provided in a good cleaning kit.
For recommendations, see your Remington®Authorized Gunsmith.
2. Select the correct gauge cleaning brush and attach the brush to
the cleaning rod. 
3. Put the cleaning brush into gun-cleaning solvent. 
4. Push the cleaning rod through the barrel several times. 
5. Remove the brush from the rod, attach tip with cleaning patch 
and push through the bore. 
6. Repeat several times, using a new, clean patch each time until 
the patch is not dirty. 
7. Remove all of the shooting residue from the locking notch 
in the barrel. See Picture 26.
8. Check the gas hole in the gas cylinder. Use a 1/16 diameter wire
to clean the gas hole. See Picture 27.
WARNING:After cleaning, make sure the barrel is free of obstructions.
TO CLEAN THE CHOKE TUBE:
1. Remove the choke tube from the barrel. 
2. Clean the choke tube, including the threads, with gun-cleaning solvent and wipe dry. 
3. Apply Rem™ Oil on threads and reassemble choke tube to the barrel following instructions on page 10.
