MAINTENANCE
With minimal but important maintenance, the F6-DP can provide many seasons of reliable
service� After each use, clean the F6-DP with a damp cloth to remove dirt and oils�
Do not use gasoline or other hazardous solvents to clean F6-DP; this can damage the
plastic enclosure� Standard household detergent or isopropyl alcohol may be used, but
do not allow liquid to penetrate the outer case�
Make sure the inlet and discharge ports are protected during transit and storage; keep the
inner diameter and the outer threads clear and clean�
NOTE:
For best results, leave the filter connected to the inlet port,
and change the filter regularly�

HP switch has opened
5. Electronics failure in motor
1. Attach power cord
2. Verify voltage at job site
3. Identify cause of breaker
activation, rectify and reset
4. Reduce pressure; rotate V2 to
Purge, then back to Recovery
5. Factory service required
Compressor starts,
but falters within
minutes; pressure
indication on HP
gauge is high
1. Recovery tank valve is not open
2. Discharge hose blocked
3. Air in system/tank
1. Open tank valve
2. Check and clear blockage
3. Bleed air from system/tank
Compressor stops
intermittently
