c) Use of washer and corrosion-resistant measures
• At the location where a bolt's head or nut comes in contact with the scanner
chassis' legs and the mount base, insert a plain washer which fits the bolt;
and, at the location where the nut comes in contact with the plain washer,
insert a spring washer, and then securely tighten the nuts (Fig 2-8).
• To prevent corrosion due to the contacts between different metals, such as
the scanner chassis' legs, installation surface, bolts, nuts, etc., cover the
bolt's head and nuts with sealant (Fig2-8).
