MAINTENANCE INSTRUCTIONS FOR CZ 75
Stripping for Cleaning - Disassembly
POINT YOUR PISTOL IN A SAFE DIRECTION!
1. Remove the magazine. The pistol must not be disassembled with the magazine inserted!
2. Put the safety to "OFF" position, in order to release the movement of the slide (not valid for versions with no manual safety).
3. MAKE SURE THAT THERE IS NO CARTRIDGE IN THE CHAMBER!
4. Retract the hammer slightly back and then release it, until it stops on half-cock (safety) notch position. In this state the handling which follows will be easier.
5. Put your left thumb through the trigger guard and with the other fingers grasp the top of the front part of the slide firmly. Push the slide slightly back until the two vertical lines on the rear part of the frame and slide are in line with each other.
6. KEEPING THE LINES ALIGNED push (tap) the slide stop from the right hand side of the weapon, i.e. using the magazine base or pistol tool provided. Remove the slide stop from the left.
7. Pull the slide and the barrel forward off the frame.
8. Remove the recoil spring and guide and finally the barrel.
No further disassembly is needed for routine maintenance. When a great number of cartridges has been fired, it is advisable to also disassemble the firing pin and magazine.
Firing Pin Disassembly
Push in the rear end of firing pin using a suitable tool, below the level of the firing pin stop, and shift the firing pin stop approx. 2 mm down. Then cover the firing pin stop with your thumb in order not to lose the spring-loaded firing pin and with the other hand pull the firing pin stop completely off the slide. Be very careful at this stage of the disassembly procedure, as the firing pin is spring-loaded and could fly out, getting lost, or even causing injury. If you have a pistol with a firing pin block safety, entrust this disassembly procedure and cleaning to a competent gunsmith!
Magazine Disassembly
To remove the magazine base, push on the base lock which sticks out through a hole in the base and slide the base about 5 mm towards the front of the magazine. Cover the base with your thumb to prevent losing the magazine spring and with the other hand take off the base from its guiding rails. Be careful during the disassembly as the spring could fly out, or even cause an injury. No further disassembly of your pistol is recommended. Should your pistol require adjustment or repair be sure the task is entrusted to a competent gunsmith!
Cleaning the Pistol
Clean the pistol:
Each time you use it
If you get your pistol wet
As soon as possible after shooting
At least once a year in a temperate climate - As often as once a month in a tropical climate, or other demanding environment
Cleaning the Barrel Bore and the Cartridge Chamber
If the pistol has not been fired or if only a few cartridges have been fired, clean the barrel bore and cartridge chamber by the clean patch attached to the cleaning rod. Repeat the cleaning, changing patches, until the last patch comes out clean. When the barrel bore is very dirty, apply a gun cleaning solution using a cleaning brush. Let the solvent act for about 10 minutes (this time may vary depending on the solvent agent being used). Then thoroughly scrub out the barrel bore. Subsequently, dry the barrel bore and cartridge chamber with a clean patch and check that all powder residues or fouling have been removed. If necessary repeat this procedure. The cleaning rod and the brush must be inserted into the barrel bore from the chamber, to prevent wear or damage to the muzzle. Pass the brush all the way through the barrel bore before reversing the movement. If you try to change directions with the brush in the barrel, the brush could stick.
Cleaning of Other Pistol Parts
Other parts of the pistol (including the external surfaces of the barrel) should be cleaned with a dry cloth, old toothbrush, brass bristle brush or a wooden scraper. Preserving oil or paraffin oil can be used for proper cleaning. Never use the agent designed for barrel bore cleaning! These solutions could remain in the joints, and after some time could cause corrosion. Check that cloth particles or brush bristles have not become lodged in any part of the pistol.
