Dry cleaning solvent P-D-680 is toxic and flammable. Wear protective goggles, face mask, and
gloves and use only in a well ventilated area. Avoid contact with skin, eyes, and clothes and
don't breathe vapor. Do not use near open flame or excessive heat. The flashpoint for type I dry
cleaning solvent is 100°F (38°C) and for type II is 140°F (60°C). If you become dizzy while using
cleaning solvent, get fresh air immediately and get medical aid. If contact with eyes is made,
flush eyes with water and get medical aid immediately.
Electrical parts, such as coils, connectors, junction blocks, insulated wiring and switches, should not be
soaked or sprayed with cleaning solutions. Clean these parts with a clean lint-free cloth moistened with dry cleaning
solvent P-D-680 (item 31, Appendix E).
When cleaning ball or roller bearings, place in a basket and suspend in a container of dry cleaning solvent,
P-D-680 (item 31, Appendix E). If necessary, use brush to remove caked grease or chips. Avoid rotating bearings
before solid particles are removed to prevent damage to races and balls. When bearings have been cleaned, spin
immediately in light lubricating oil (item 27, Appendix E) to remove solvent.
Do not clean preformed packings or other rubber parts in dry cleaning solvent. Wipe with clean, dry lint-
For exterior cleaning of frame and structural components, use detergent (item 17, Appendix E), in a
solution as recommended on the container. Leave application on items surface for approximately 10 minutes before
rinsing. Rinse with hot or cold water under pressure. If available, use hot water under 80 to 120 lb (36 to 54 kg)
pressure. An ordinary garden hose may be used if no other equipment is available. If pressurized water supply is not
available, wash painted surfaces with a solution of 1/4 cup of soap chips (item 7, Appendix E), to one gallon of water.
Before disassembly of sweeper, clean exterior parts of sweeper thoroughly with dry cleaning solvent P-
D680 (item 31, Appendix E) to remove accumulated mud, tar and grease.
Do not use gasoline, diesel fuel, or other petroleum base products to clean or preserve hydraulic
system components. Use of petroleum base products can change the lubricating quality of
hydraulic oil and cause failure or damage to equipment.
When cleaning hydraulic system components, use petroleum-free solvents. Clean and dry parts
thoroughly to make sure no residue remains. If preservative coating is required before reassembly, apply a light film of
preservative oil, (item 27, Appendix E). If petroleum-free solvents are not available for cleaning, use hydraulic fluid
compatible with that used in the sweeper system.
Removal and Disassembly of Components.
When unpacking items, remove all packing material, barrier paper, tape, plastic bags, protective caps, and
protective grease coatings.
