Introduction
We want you to be completely satisfied with your
new product, so feel free to contact your local
Authorized TORO Distributor for help with service,
genuine replacement parts, or other information you
may require.
The warning system in this manual identifies
potential hazards and has special safety messages that
help you and others avoid personal injury, even death.
DANGER, WARNING and CAUTION are signal
words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
DANGER signals an extreme hazard that will cause
serious injury or death if the recommended
precautions are not followed.
WARNING signals a hazard that may cause serious
injury or death if the recommended precautions are
not followed.
CAUTION signals a hazard that may cause minor or
moderate injury if the recommended precautions are
not followed.
Two other words are also used to highlight
information. “Important” calls attention to special
mechanical information and “Note” emphasizes
general information worthy of special attention.
The left and right side of the machine is determined
by standing behind the machine in the normal
operator’s position.

5. Reach underneath the hood and open the bleed
valve on the main valve at the rear of the
machine. Bleed the system until a steady flow of
water comes from the outlet, then close the
valve.
POTENTIAL HAZARD
•Chemicals can be hazardous and can cause
personal injury.
WHAT CAN HAPPEN
•Chemicals which are handled incorrectly
can pose a danger to personal health, and
can damage equipment.
HOW TO AVOID THE HAZARD
•Carefully read the directions printed on the
chemical manufacturer’s labels before
handling chemicals. Instructions on
chemical manufacturer’s container labels
regarding mixing proportions should be
read and strictly followed.
•Keep chemicals from skin. If chemicals
come in contact with body, wash off
immediately with clean water and
detergent.
•Always wear goggles and other protective
equipment as recommended by the
chemical manufacturer.
6. Carefully add the additives to the chemical tank,
then fill the tank with fresh filtered water for the
desired concentration. Refer to Application Rate
on page 15.
7. Adjust the mixing ratio as follows:
(Refer to the Application Rate and Calibration
sections.)
A. Remove the anti-rotation lock pin (Fig. 16).
B. Rotate the ratio adjuster sleeve up or down
until the top of the sleeve aligns with the
line under the desired mixing ratio
(Fig. 16).
C. Align the holes in the ratio adjuster sleeve
with the flats on the cylinder, then reinstall
the anti-rotation lock pin (Fig. 16).

Operation
15
IMPORTANT: Don’t force the ratio adjuster
sleeve above the maximum setting of 1%
(1:100) or below the minimum setting of 0.2%
(1:500) (Fig. 16).
Note: Settings in the gray zone (below 0.5%
or 1:200) will cause the pump to take
longer to prime. For faster priming, set
the mixing ratio to the maximum
setting (1% or 1:100). After the pump
is primed, reset the mixing ratio to the
desired setting.
The ratio adjuster sleeve can be moved
with water flowing, while the injector
is under water pressure or when the
bypass knob is in the bypass position
(Fig. 16).

8. Start the engine. Move the throttle to the Fast
position and disengage the parking brake.
9. Aerate normally.
10. When you’re finished injecting, add one (1)
quart or more of fresh filtered water to the
chemical tank. Operate the HydroJect3000
Aerator and injection system until the fresh
water is gone.
11. Rinse the chemical tank with fresh filtered water.
IMPORTANT: Additives allowed to remain in
an inactive injector can dry out and foul or
damage the lower end at the next start-up.
Application Rate
1. Adjust the HydroJect3000 Aerator to a
three-inch (3”) hole spacing. Refer to the
Maintenance section in the HydroJect3000
Aerator Operator’s Manual.
2. Determine how many ounces of additive per
1000 square feet you want to apply.
3. Refer to the Application Rate table on the
following page to determine the ratio adjuster
setting and tank mixture concentration (in
percent) needed to apply the desired number of
ounces of additive per 1000 square feet. Use 100
percent concentration whenever possible to
reduce additive handling and mixing.
4. Set the ratio adjuster to 1:100 (1.0%), 1:128
(0.8%), 1:200 (0.5%) or 1:500 (0.2%) as
required.
5. Add the required number of ounces of additive
to the chemical tank, then fill the tank with fresh
filtered water as required to the very top of the
neck, then stir.
Note: The decal on the injector is just a
starting point. Further calibration may
be required. See the Calibration
section.
Example
Say you want to apply an additive at an approximate
rate of five (5) ounces per 1000 square feet.
1. Refer to the 3.00” Hole Spacing table shown
below. The table shows that to apply additive at
a rate of five ounces per 1000 square feet, the
ratio adjuster should be set to 1:128 and the tank
mixture concentration should be 30 percent.

8. Calculate the amount of tank mixture used to get
a given application rate using the formula:

Operation
18
Ounces of Additive
per 1000 ft.2Path WidthPath Length xx
1000 x Tank Concentration
100
or, as in this example,
5 ounces per 1000 ft.2100 ft.2.75 ft. xx = 4.58 oz.
1000 x 30
100
The amount of tank mixture used for the
100-foot length should be approximately 4.6
ounces.
9. Aerate the 100-foot length normally.
10. Determine the amount required to refill the
chemical tank to the marked line (marked in step
6 on the preceding page).
11. Adjust the ratio adjuster if required and repeat
the calibration procedure from step 9 above until
the amount of tank mixture used to aerate the
100-foot length equals 4.6 ounces.
