To disconnect an air hose or an air tool:

Confirm that the outlet pressure is at zero (0) psi.

When disconnecting a hose from 1/4-in. quick coupler,
always firmly hold release end of hose.

Pull back on the release sleeve on the 1/4-in. quick
coupler.

With a firm grip, pull out the quick-connect air fitting that
is attached to the quick coupler.
BREAK-IN PERIOD
Before first use, install a fully charged 4.0 Ah battery pack,
then run the air compressor at zero tank pressure with the
drain valve fully open for 30 minutes or until the battery pack
is completely discharged, whichever happens first.
TURNING THE AIR COMPRESSOR ON/OFF
See Figure 3, page 14.

Install the battery pack.

Move the Auto On/Off switch to the AUTO ON (I) position
to power the compressor on.

To turn the air compressor off, move the Auto On/Off
switch to the OFF (O) position.
NOTE: When the compressor is in the AUTO ON (I) position,
the air compressor will automatically turn back on when
the designated tank air pressure drops below the preset
pressure limit. It will also shut off again when the cut-off
pressure is reached.
WARNING:
Never exceed the air tool’s pressure rating as recom-
mended by the manufacturer. When using this air com-
pressor as an inflation device, always follow the maximum
inflation guidelines stated by the manufacturer of the item
being inflated.
WARNING:
Always ensure the switch is in the OFF (O) position and
the regulator pressure gauge reads zero before changing
air tools or disconnecting the hose from the air outlet.
Failure to do so could result in possible serious personal
injury.
