Green: Aerate start (engage) switch closed. If the red
and yellow lights are on, the green light will stay on
until either the red or yellow goes off.
Yellow: Pump start limit switch closed (machine
lowered to aerate position) and water pressure switch
closed (water pressure of more than 30 psi) and
accumulator charge pressure switch (nitrogen pressure
more than 1800 psi).
Transport Operation
Use the traction bail to slow the machine while crossing
undulating terrain to avoid loss of control. The smooth tires
do not grip turf very well so use caution when transporting
the machine. Always approach rough areas at a reduced
speed and cross severe undulations carefully.
Inspection and Clean-Up After
Use
At the completion of operation, thoroughly wash the
machine with a garden hose without a nozzle so excessive
water pressure will not cause contamination and damage to
seals and bearings. After cleaning, it is recommended the
machine be inspected for possible hydraulic fluid or water
leaks and damage or wear to hydraulic, water, and
mechanical components.
Pushing or Towing the Machine
In an emergency, the machine can be pushed or towed for a
very short distance. However, we do not recommend this as
standard procedure.
Important Do not push or the tow machine faster than
3 MPH because pump damage may occur. If the machine
must be moved a considerable distance, transport it on a
truck or trailer or pull it with the traction wheel raised and
secured to a dolly. Whenever the machine is pushed or
towed, the bypass valve must be opened. The hook on the
front of the handle is used as a tie-down only, not a hitch
point.
1. Unlatch and raise the hood.
2. Locate the bypass valve cap on the left side of the
hydraulic pump (Fig. 14).
3. Rotate the valve cap counterclockwise, move the
machine to the desired location, and close the valve cap.
4. Lower the hood and secure the latches.
Important Do not run any chemicals through the
Hydroject water system (except Toro Wetting Agent
86–8530). Chemicals can have corrosive effects on
machine components and environmental laws and concerns
exist when injecting chemical sub–surface.
