For clarity in this illustration,
the air hose and regulator
to the pump are shown
above the level of the air
inlet. For efficient operation,
these parts must be level
with the air inlet of the
pump.

The system in Fig. 2 is for the fast evacuation of gear
oil from vehicles. One centrally mounted Graco Husky
1040 pump can have suction line drops to as many as
four service bays, when activated singly. One control
valve at each bay remotely activates the pump and
quickly suctions the gear oil. Interchangeable, nylon
suction wands are available to fit most differentials and
transmissions; see page 8. This system can also be
used to remove waste oil from rolling waste oil drain
carts, using a high capacity wand, or Suction Tube
222–178; see page 10.
Installation
See pages 7 to 11 for detailed information on installing
the evacuation system accessories.
Starting and Adjusting the Pump
1.
Be sure the pump is properly grounded and
bonded. Read and follow FIRE OR EXPLOSION
HAZARD, on page 3.
2.
Be sure all fittings are tight. Use a compatible liquid
thread sealant on all male threads. Do not over-
tighten the fittings into the pump.
3.
Install a ground wire and clamp.
4.
Attach an appropriate wand to the control valve.
See Suction Differential Kit 221–146.
5.
Connect the quick coupler of the Air Supply Kit
221–147, to the pump air inlet. Open and set the air
regulator to about 3.5 bar (50 psi).
6.
Place the suction wand in the differential, transmis-
sion, or fluid to be suctioned.
7.
Pull down the handle of the Evacuation Control
Valve, 220–969, to start the pump.
8.
Adjust the regulator until you get good suction. Do
not use higher air pressure than needed.
9.
If you are using a Husky 1040 pump, perform the
Vacuum Test given in the pump manual.
10.
Always push the control valve handle up when you
are finished. Place the wand in the holder on the
control valve.
NOTE:
Be sure the control valve handle is closed
when the evacuation is completed. Failure to close it
may prevent other service bays on the line from work-
ing at optimum performance.
