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.

Safety
Safety Instructions
POTENTIAL HAZARD
•Incorrect injection ratios can produce an
unsafe concentration level in the outlet
water.
WHAT CAN HAPPEN
•Unsafe concentration levels in outlet water
caused by incorrect injection ratios can
pose a danger to personal health, and can
damage equipment.
HOW TO AVOID THE HAZARD
•Determine the correct solution injection
ratios.
•Adjust the injector to obtain the desired
solution concentrations in the outlet water.
•Ensure that the correct injection ratios are
being maintained.
The HydroJectInjection System is a water-driven
liquid injector designed to inject proportionate
amounts of liquid additives that are recommended
and approved. It is the responsibility of the operator
to determine correct solution injection ratios, adjust
the Injector to obtain the desired solution
concentrations in the outlet water, and ensure that
proper injection ratios are being maintained. Incorrect
injection ratios can be harmful to personal health, the
environment or equipment.
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.
Hazard control and accident prevention are dependent
upon the awareness, concern, and proper training of
the personnel involved in the operation, transport,
maintenance, and storage of the machine. Improper
use or maintenance of the machine can result in injury
or death. To reduce the potential for injury or death,
comply with the following safety instructions.
IMPORTANT: It is the responsibility of the
operator to comply with federal, state and
local ordinances or regulations pertaining to
application.

Safety

1. Read and understand the contents of this
Operator’s Manual, and the Operator’s Manual
for the HydroJect3000 Aerator before
operating the machine. Become familiar with all
controls and know how to stop quickly. Free
replacement manuals are available by sending
the complete Model and Serial Number to:
The TORO Company
8111 Lyndale Avenue South
Bloomington, Minnesota 55420
2. Keep all shields and safety devices in place. If a
shield, safety device or decal is damaged or
missing, repair or replace it before operating the
machine. Also tighten any loose nuts, bolts or
screws to ensure that the machine is in safe
operating condition.
3. Wearing safety glasses, safety shoes, ear
protection and a helmet is advisable and required
by some local ordinances and insurance
regulations. Always wear goggles and other
protective equipment as recommended by the
chemical manufacturer.
4. Never use additives in the water supply system
other than those listed in this manual as
recommended and approved.
5. Make sure all hydraulic line connectors are tight,
and all hydraulic hoses and lines are in good
condition before applying pressure to the system.
6. Make sure all waterline connectors are tight, and
all water and additive hoses and lines are in good
condition before applying pressure to the system.
7. Before disconnecting or performing any work on
the water system, relieve all pressure in the
system by stopping the engine and opening the
bleed valve. Opening the bleed valve allows any
trapped water to escape from the system, and
also allows the accumulator piston to move to
the bottom of the accumulator cylinder.
8. Perform only those maintenance instructions
described in this manual. If major repairs are
ever needed or assistance is desired, contact an
Authorized TORO Distributor. To ensure
optimum performance and safety, always
purchase genuine TORO replacement parts and
accessories to keep the TORO all TORO.
NEVER USE “WILL–FIT” REPLACEMENT
PARTS AND ACCESSORIES MADE BY
OTHER MANUFACTURERS. Look for the
TORO logo to ensure genuineness. Using
unapproved replacement parts and accessories
could void the warranty of The TORO Company.
