Low Engine Fuel Level Switch
At three month intervals, test the low engine fuel level switch circuit as follows:
•
Start the machine.
NOTE: Do not press the load button.
•
Disconnect the switch, the machine should shutdown.
•
Re-connect the switch.
At twelve month intervals, test the low engine fuel level switch by removing and operating the
float manually.
CAUTION
!
Never remove or replace switches when the machine is running.
Scavenge Line
The scavenge line runs from the combined orifice/drop tube in the separator tank, to the orifice
fitting located in the airend.
Examine the orifice, check valve and hoses at every service or in the event of oil carryover into
the discharge air.
It is good preventative maintenance to check that the scavenge line and tube are clear of any
obstruction each time the compressor lubricant is changed as any blockage will result in oil
carryover into the discharge air.
