Checking The Interlock System - Toro 09802 HydroJect 3010 Operator's Manual

6. Reach under the hood and open the bleed valve on the
main valve at the rear of the machine (Fig. 11). 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 (Fig. 12) may be
opened slightly (cracked) to provide continuous
flushing during operation of the machine.

8. Start the engine; refer to Starting and Stopping the
Engine, page 18. 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.

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.
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 down
to allow multiple shots while machine is stopped.
Important Hole depths can reach 20 inches or more
when 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.
