Cleaning and Maintenance
NOTE: The service life and performance of the HK45 is dependent upon the
correct handling and proper care by the operator.
Materials Required - At a minimum, the following materials are suggested to
properly clean the HK45.
• Cleaning rod with handle and patch holder
• Nylon toothbrush
• Bronze bristle bore brush (.45 caliber)
• Cleaning patches (.45 caliber)
• Lint-free wiping rag
• Cleaning solvent/lubricant, MIL-L-63460 (CLP) + MIL-L-14107 (LAW)
• Cotton swabs
CAUTION: Use safety goggles when using solvents and hearing protection
if using compressed air.
Modular Pistol Cleaning Kits (HK article no. 701958 .45 ACP pistol) are
available from HK for thorough cleaning of the HK45 and other firearms.
Cleaning Intervals -There are two types of operator cleaning for the HK45.
Normal and Major cleaning.
Normal Cleaning - Performed after each firing, every 500 rounds (without
sound suppressor, 250 rounds with sound suppressor) or every twelve (12)
months.
Major Cleaning - Often referred to as "detailed cleaning". Performed after
the firing of 1000 rounds (500 suppressed) or when the pistol is exposed to, or
laden throughout with sand, dust, water (especially salt water), or other visible
contaminants or foreign matter.
Normal Cleaning
Slide
• Gently scrub all internal surfaces of the slide using the nylon
toothbrush moistened with solvent.
• Remove all loose fouling from all surfaces of the slide using a rag
and cotton swabs.
Recoil/buffer spring assembly
• Remove all visible fouling using solvent, a nylon toothbrush, a rag
and cotton swabs.
Barrel (with locking block)
• Moisten a bronze bore brush with solvent and scrub the bore from
chamber to muzzle at least six (6) passes, back and forth.
• Remove the loose fouling from the bore using cleaning patches.
HK45 & HK45 Compact SECTION 7
• Gently scrub the exterior of the barrel and locking block with the
nylon toothbrush moistened with solvent.
• Remove all loose fouling from the exterior of the barrel and barrel
threads (where applicable) using a rag and cotton swabs. Place a
drop of lubricant on the barrel O-ring during cleaning and replace
the O-ring after 5,000 rounds of suppressor use (20,000 rounds
of standard use). Spare O-rings are provided with each new HK45
series pistol. Prolonged use of +P ammunition through the pistol
with the sound suppressor attached is not recommended.
Frame
• Gently scrub all internal surfaces where carbon fouling is present
using the nylon toothbrush moistened with solvent. Concentrate on
the area normally covered by the slide.
• Using a rag and cotton swabs, remove all loose fouling from all areas
of the frame.
Magazine
• Gently scrub the top of the magazine, concentrating on the follower
and feed lips, using the nylon toothbrush moistened with solvent.
• Using a rag and cotton swabs, remove all loose fouling from all
surfaces of the magazine.
Major Cleaning
Major Cleaning is the same as normal cleaning except that:
• The magazine is disassembled for cleaning.
• All parts should be rinsed with, or immersed in solvent and
thoroughly scrubbed with a nylon brush. The parts can then be dried
using compressed air or with a rag and cotton swabs.
NOTE: Parts of the HK45 can be immersed in any cleaning solvent that it is
safe to put your hands into, including ultrasonic cleaning solution. Painted
surfaces of the pistol (i.e. control lever, white index line on frame, and
extractor markings) can be removed by using ultrasonic cleaning machines,
so care must be taken to protect these painted surfaces.
