1. Pre-filter
8. Start the engine; refer to Starting and Stopping the
Engine. Move the throttle to the FAST position and
disengage the parking brake.
9. Engage the traction bail and approach the area to
be aerated. Make sure that there are no obstructions
between the aerator and water supply. Always
maintain awareness of what lies ahead in the
direction of forward travel.
10. Engage and hold the transport/aerate toggle switch
to fully lower the machine onto the rollers. Release
the switch when the machine is fully lowered; then
press the engagement button to start water injection.
Note: The injection operation starts approximately
4-5 seconds after the pump engages. Also, the
injection system will automatically stop if the
traction bail is not engaged within 3-4 seconds after
starting the water system.
11. When aerating, work moving perpendicular from
the water supply to avoid running over the garden
hose. Use the front edge of the hood or rear corner
of the frame to align rows, if desired. When at the
end of a row, make an "S" maneuver and reverse the
direction of the aerator. Do not make sharp turns
on a green or scuffing from the tire may occur.
Always maintain awareness of what lies ahead in the
direction of forward travel.
12. Regulate the roller spray wash, if required, to
remove debris from the rollers.
Note: A small amount of water from the regulator
bypass may come out of the spray wash nozzles
even with the spray wash in the OFF position.
13. In areas where greater hole depth or more frequent
holes are desired, the engage button can be held
2. Valve
down to allow multiple shots while machine is
stopped.
Important: Hole depths can reach 20 inches
or more when stationary or making multiple
shots, so be aware of what is buried below the
turf. Also, an excessive amount of holes and
muddy turf conditions may occur when making
multiple shots.
14. To stop water injection, press the red button. The
system continues for a few seconds after the button
is pressed. Raise the machine to the transport
position, disconnect the supply hose, and move to
the next location.
Checking the Interlock System
If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly, causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
The purpose of the safety interlock system is to prevent
the engine from cranking or starting unless the traction
bail is in NEUTRAL and prevents the water system
from engaging if the machine is in the transport (raised)
position. It also stops aeration if the traction bail is
released while operating or if the machine is raised to
the transport position.
To do a functional check of interlock system:
1. Position the machine in a flat, open area on rough
turf and away from buried wires, plumbing, etc.
Stop the engine.
2. Move the traction bail up and down while trying
to start the engine. If the engine cranks, there is a
malfunction in the interlock system that must be
corrected. If the engine does not crank, proceed
to step 3.
3. Connect the water supply to the machine. Turn
on the water supply and bleed all air out of the
system. The water pressure must be 30 psi or more.
Start the engine. Raise the machine to the transport
position (up off the rollers). Push the aerate
ENGAGE button. If the water pump engages and
the machine begins aerating, there is a malfunction
