1. Screw male coupling onto the machine. Do not
overtighten.
2. Screw female coupling onto male end of garden
hose. Be sure the hose end is in good condition so
a leak does not occur. Do not overtighten.
3. To connect, push female coupling onto male
coupling all the way until it clicks twice to assure
full flow of water to the pump.
Caution: Failure to push female coupling on all
the way can damage the pump if allowed to run
dry.
4. Turn on water supply: If leak occurs, retrace
steps 1 to 3, making sure connections are tight
and that couplings are not reversed.
Caution: The male and female connection are
not the same thread size. Reversing the con-
nections will damage the coupling and cause a
water leak preventing the pump from priming
properly.
Suction: Observe the following if you are drawing
water from an open container:
1. Unscrew the union element from the water
connection of the appliance, and attach a suc-
tion hose with filter (order no. 4.440-238) directly
to the appliance.
2. Allow the pump to operate without the high-
pressure hose until water appears at the high-
pressure outlet without any more bubbles.
3. Then re-attach the high-pressure hose.
