Cleaning Instructions (General)
Keeping the generator set clean of any oil and dirt is recommended for both appearance and
maximum service life of the equipment. The frequency of cleaning will be dependent on local
conditions and the severity and frequency of operation.
NOTE: Do not use high pressure water, steam, or solvent on the exterior
finish of the unit housing.
EXTERIOR FINISH CARE
This unit was painted and heat cured at the factory with a high quality, thermoset polyester
powder coating. The following care will ensure the longest possible life from this finish.
1. If necessary to remove dust, pollen, etc. from housing, wash with water and
automotive shampoo or mild dish washing liquid detergent. Do not scrub with
a rough cloth, pad, etc.
2. To remove grease, a fast evaporating alcohol or chlorinated solvent can be
used. Note: This may cause some dulling of the paint finish.
3. If the paint has faded or chalked, the use of a commercial grade, non-abrasive
car wax may partially restore the color and gloss.
Field Repair of Texture Paint
1. The sheet metal should be washed and clean of foreign material and
thoroughly dried.
2. Clean and remove all grease and wax from the area to be painted using Dupont
3900S Cleaner prior to sanding.
3. Use 320 grit sanding paper to repair any scratches or defects.
4. Scuff sand the entire area to be painted with a red Scotch Brite Pad.
5. Wipe the area clean using Dupont 3900S.
6. Blow and tack the area to be painted.
7. Apply a smooth coat of Dupont 1854S Tuffcoat Primer to all bare metal areas
and allow to dry.
8. Apply 2 medium -wet coats of Dupont 222S Adhesion Promoter over the entire
area to be painted, with a 5 minute flash in between coats.
9. To apply the texture coat, use Dupont 1854S Tuffcoat Primer. The proper
technique to do this is to spray the Tuffcoat Primer using a pressure pot and
use about 2-5 pounds of air pressure. This will allow the primer to splatter,
causing the textured look.
