4.1.6 Airproof Rubber Ring Replacement
Caution
If the Airproof rubber ring is damaged, make
sure that there is no water-ingression in the
scale.
1. Remove the 8 Screws (M4x10) on the SUS
ring inside.
2. Remove the Diaphragm and SUS ring
outside.
3. Perform the procedure in reverse for
assembly.
Caution
When re-assembling the scale, fasten screws
tentatively, then tighten them completely one by
one in a diagonal sequence.
If you strongly tighten a particular point first, the
water proofing property will be deteriorated
because you cannot push in the packing
between the upper case and the base evenly.
