R
When connecting hoses from power
source to the tool. It is
recommended that you connect the
return hoses first and disconnect last
to minimize or avoid trapping
pressure within the tool.
When connecting the quick couplers,
the flow should run from male
coupler to the female coupler. The
female coupler on the tool is the
inlet. Quick couplers are marked
with a flow direction arrow.
CAUTION: DO NOT PULL ON
HOSES TO DRAG POWER TOOL.
NOTE: When possible, connect the
free ends of uncoupled hoses to
prevent build up in the hoses. The
sun can also increase pressure in
the hoses and make connecting
them difficult.
