3.3. MAINTENANCE PROCEDURES

3.3.1. PS28 MAINTENANCE

The PS28 maintenance consists of external inspection of its com-

ponents for serviceability, cleaning and installation of the standard

and optional accessories. Maintenance instructions covered else-

where in this manual (PMCS, troubleshooting, etc.) are not repeat-

ed in this section.

CAUTION
The PS28 is a precision electro-optical instrument and must be

handled carefully at all times to prevent damage.

3.3.2. CLEANING PROCEDURES

A. Cleaning of the PS28

1. Gently brush off any dirt from the sight body using only a clean

soft cloth.

2. Moisten the cloth with fresh water and gently wipe the external

surfaces (except glass surfaces).

3. Dry any wet surfaces (except lenses) with another dry and clean

soft cloth.

4. Using lens brush, carefully remove all loose dirt from glass sur-

faces.

5. Slightly dampen a cotton swab with ethanol and lightly and slow-

ly wipe the lenses and the light sensor. Clean the glass surfaces

by circular movements from the centre to the edge, not touching

the lens holders and changing cotton swab after each circular

stroke. Repeat this step until the glass surfaces are clean.

B. Cleaning of Accessories

Clean accessories with a soft brush (cloth) and soap and water as

required.

CAUTION
Dry thoroughly each item before replacing into the storage

case.
