EVACUATE OIL FROM HYDRAULIC SYSTEM.
The following procedure creates a
vacuum in the hydraulic reservoir.
The vacuum draws hydraulic oil from
pumps, motors, and hoses, into the
reservoir. This procedure is required
if replacing hydraulic hoses or tubes
to the propulsion pumps or motors,
auxiliary vibration pump.
Turn on electric vacuum cleaner and tap
vacuum cleaner hose (1) with hammer to
evacuate all loose dust and debris. Turn
vacuum cleaner off. Wipe outside and inside
of nozzle with a cleaning cloth.
Cleaning solvent, P-D-680, is TOXIC
and flammable. Wear protective
goggles and gloves. Use only in a
well ventilated area. Avoid contact
with skin, eyes, and clothes, and do
not breathe vapors. Keep away from
heat or flame. Never smoke when
using solvent; the flashpoint for Type
lII cleaning solvent is 200°F (93,3°C).
Failure to do so may result in injury
or death to personnel.
If personnel become dizzy while
using cleaning solvent, immediately
get fresh air and medical help. If
solvent contacts skin or clothes,
flush with cold water. If solvent
contacts eyes, flush eyes with water
and get immediate medical attention.
Use a cleaning cloth and cleaning solvent to
clean contaminants from nozzle of vacuum
