9. Roll a NEW tissue into a tapered rod of appropriate size. Force the tissue through the
cylinder bore whilst rotating. Ensure that the tissue is a tight fit inside the bore so that
dirt and contamination is removed.
10. Repeat step 9, using a NEW tissue, but from the opposite end of the cylinder.
11. Immerse the cylinder in a suitable, clean solvent.
12. After removal from the solvent, using a NEW tissue, repeat the cleaning procedure in
step 9 & 10.
Piston Reassembly
13. Holding the piston by the larger “head” end, dip the other end into a container of
clean operating fluid, and transfer to the bore in the underside of the cylinder.
Allow the fluid to run through the bore. Repeat this 2 or 3 times to ensure an even
film of fluid exists in the cylinder bore.
14. Carefully introduce the piston into the underside of the cylinder, and push gently
through (the piston will normally slide freely through due to its own weight).
15. NEVER FORCE THE PISTON INTO ITS CYLINDER OR DAMAGE WILL
RESULT.
16. If resistance is felt, re-clean piston, cylinder or both. If, after repeated cleaning, the
piston still will not slide freely within the cylinder, then permanent damage may have
occurred. In which case, the parts should be returned to the factory for evaluation or
replacement.
17. Place cylinder retainer over the piston, and locate on the stepped end of the cylinder.
18. Ensure that the weight carrier (1) is clean (especially the central mounting hole), and
locate on the recessed end of the piston. Secure with set screw — Do not over-tighten.
19. Carefully screw the assembly into the instrument, ensuring that the PCU seal inside
the housing is clean, undamaged, and correctly re-fitted.

Caution
The piston and cylinder assembly is a matched pair, which is
calibrated and adjusted to a calculated mass figure. If, for any
reason, the piston or cylinder becomes damaged, then the
entire assembly must be replaced. The replacement assembly
consists of the following components: Item numbers
