Maintenance Operation & Maintenance Manual

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.
Compressor Oil Filter
Refer to the MAINTENANCE INTERVAL CHART in this section for the recommended
servicing intervals.

WARNING
!
Do not remove the filter(s) without first making sure that the machine is
stopped and the system has been completely relieved of all air pressure.
(Refer to STOPPING THE UNIT in the OPERATING INSTRUCTIONS
section of this manual).
Clean the exterior of the filter housing and remove the spin–on element by turning it in a
counter–clockwise direction.
