Water Supply
Recommended source with 7-8 gallons per minute.
A minimum pressure of 30 p.s.i. at the machine is
required for the pump to engage. Maximum allowable
pressure of 200 psi. Although irrigation water pumped
from ponds or effluent holding pools can be used, not
all conditions can be handled by the filtration system.
Additional or alternative filtration may be required.
Operating Procedure
1. Make sure that the wires are installed on the spark
plugs and the fuel shut-off valve is open.
2. Uncoil a garden hose, making sure that there are no
kinks or bends in the hose. Lay out the hose so that
there are no obstructions between the machine and
the area to be aerated. Turn on the water supply to
purge any air from the hose. Turn off the water.
3. Connect the hose adapter (Figure 12) to the garden
hose, then connect the adapter to the quick coupler
on the side of the machine.

4. Turn on the water supply and check the water
pressure. The water pressure must be at least 30
p.s.i.. If the system pressure is not 30 p.s.i., make
sure that the hose is not kinked or obstructed, the
water supply is turned on, and the water filter is not
plugged.
Do not operate the engine while bleeding the
filter head.
5. Reach under the fuel tank and press the bleed
button on top of the water filter head (Figure 13).
Hold the bleed button down until all air is purged
from the filter and water comes out of the opening.

6. Reach under the hood and open the bleed valve
on the main valve at the rear of the machine
(Figure 14). Bleed the system until a steady flow of
water comes from the outlet; then close the valve.

7. If desired, the valve on the pre-filter (Figure 15) may
be opened slightly (cracked) to provide continuous
flushing during operation of the machine.
