1. Remove the 6 screws (70) around the outer edge of the battery compartment cover (69).

2. Lift out battery (66) and unplug connector.

3.7 Inspection and Cleaning

All weigher parts should be carefully cleaned and inspected prior to assembly to assure proper working

conditions.

All parts, with the exception of all electronic components, should be cleaned with kerosene only. Do not use

carbon tetrachloride, acetone, or any other organic cleaning agent. The use of organic-based agents is ex-

tremely detrimental to the nonmetallic elements within the unit and will cause premature failure. Electronic

components should be removed from the weigher and cleaned in alcohol and thoroughly dried before reas-

sembly. While cleaning electronic components, do not disturb the factory settings of the potentiometers.

Under no circumstances should the weigher be cleaned with steam or pressure type cleaners. Avoid using

caustic or acid base solutions as these can damage seals and other components.

location of numbered parts.

1. Inspect piston pivot (13) for excessive wear and proper fitting.

2. Inspect platform buttons (43) for excessive wear.

3. Inspect platform load strips (18) and (19) for signs of unusual wear at contact points and proper fitting

of resilient retainer (17). Depth of wear must not exceed 0.002 inch.
