| 1. Power on light does not light.
Unit will not start: |
| a. Check to see that the unit is
plugged in. |
| b. Check to insure that the power
switch is "ON". |
| c. Check power circuit breaker or
fuses to outlet that the unit is plugged into. |
| d. Check fuse under top panel. |
|
2. Oil level indicator is
inaccurate: |
| a. Follow procedures for initial
start-up and calibration. |
| b. Check condition of level sensing
float in onboard holding tank. |
| c. Check to insure that the float
assembly moves up and down freely. |
| d. Contact John Read at (925)

3. Evacuation Slow or Doesn't
Occur. Vacuum gauge reads low: |
| a. Check for maximum reading by
blocking the end of the wand; Note vacuum. |
| b. Remove wand from hose and black
end of hose. Note vacuum. If higher reading, check wand condition
carefully for obstructions, splits, tears, kinks, etc. |
| c. If still low, remove evacuation
hose from Y-strainer of machine. Plug hole on machine, note vacuum
read. If higher than previous reading, carefully check condition
of evacuation hose. |
| d. Clean out Y-strainer - take out
plug with screen attached and blow out debris in the screen with
an air hose. |
| e. Close intake valve for proper
operation. |
| f. If reading is still low, contact
John Read at (925) 734-5800 |
|
4. Evacuation does not occur.
Vacuum gauge reads 26" or higher: |
| a. Wand or evacuation hose
obstructed. A piece of rod will clear the wand, (use carefully;
blunt end of a rod with file). |
| b. Suspended ceiling support wires
available in 10' lengths can be purchased at most lumber yards or
hardware stores. |
| c. If wand is clear and condition
persists, remove hose from machine and clear as necessary. |
|
5. High level light is lit.
Evacuation does not occur: |
| a. Set mode switch to discharge to
return evacuated oil to the facility waste oil tank. |
| b. Remove back cover, visually check
oil level, note position of the electrically actuated valves. See
description on Page23 for valve versus mode position. If valves
are not in the proper position, depress the "Clutch"
button on the actuator and manually move the valve to the desired
position. The tank should now be empty and the high level light
should go off. |
