The Battery Filling System direct fill link (part# DF710S and
DF710ST) is a compact version of the water delivery gun.
A one-piece on/off valve replaces the trigger nozzle of the gun. The link also
comes with the optional connectors. The
DF710S quick connector has a grey connector (09KUM1) that pulls back to connect
and disconnect. The G1000ST has a blue
connector (09FBLU1) that is easier to use – it just snaps in to connect and has
a push button to release.
