PRECAUTIONARY STATEMENTS
Listed below are the definitions for the various levels of hazards. It is important that the operators of this equipment and
people who service units read and understand all warnings as they relate to this equipment operation.
DANGER – indicates a hazardous situation, which if not avoided WILL result in DEATH or SERIOUS INJURY if you do
not follow proper instructions.
WARNING – indicates a hazardous situation, which if not avoided COULD result in DEATH OR SERIOUS INJURY if you
do not follow proper instructions.
CAUTION – indicates a hazardous situation, which if not avoided COULD result in MINOR to MODERATE INJURY if you
do not follow proper instructions.
NOTICE – addresses practices not related to personal injury, such as property damage or damage to the equipment.
The following warnings are generally in the Operator’s Manual for each specific unit or are generic safety messages if an
Operator’s Manual does not have these safety messages. Other safety alert messages may be in other sections of the
Parts and Service Manual or in an Operator’s Manual. You must read and obey all safety alert messages in any manual
produced by Heil to support your unit.
WARNING
Failure to follow all instructions and safety precautions in this manual, in the Service Manual, in other manufacturer’s
manuals and on the safety decals attached to the product could result in serious injury or death to operators or bystanders
and/or damage to property. Do not operate this vehicle before you read and understand the Operation Manual, the Parts
Service Manual for this unit, other applicable manufacturer’s manuals and the safety decals on the product. Each operator
of this unit must read and understand all directions in this manual before they first operate this vehicle. Keep this manual
in the cab for new operators and to remind all operators about safe use.
WARNING
Never weld on a compressed natural gas vehicle unless the compressed natural gas fuel system has been purged with
inert gas.
DANGER
Do not operate the unit or perform repair or maintenance procedures on the unit until you read and understand all of the
instructions in this manual. Failure to do so can result in death or serious injury to operators or bystanders.
DANGER
Make sure the unit is on firm, stable ground before you raise the body and clear the area of all unnecessary people. Do not
prop a body unless it is on firm, stable ground. A unit not on firm, stable ground can roll when raising or propping the body.
This can cause death or serious injury to you or bystanders.
DANGER
Always prop the tailgate when you leave it raised for maintenance, service or cleaning procedures. Any part of your body
between the unit’s body and the tailgate while you prop the tailgate or when the tailgate is propped is dangerous. Death or
serious injury can occur if any part of your body is between the tailgate and the body if the tailgate suddenly closes.
DANGER
A tailgate in motion is dangerous. Serious injury or death can occur if a person is struck by a moving tailgate or becomes
trapped between the tailgate and the body. Clear the area near the tailgate of all unnecessary people before you lower the
tailgate.

DANGER
The packer and crusher panels are dangerous. They can cause death or serious injury if a person is inside the hopper.
Make sure no one is inside the hopper before you begin a packer or crusher function. Put the unit in the Lock-Out/Tag-Out
mode if it is necessary to enter the hopper area.
DANGER
Keep all parts of your body out from underneath the unit’s body and away from the cylinders when raising or lowering the
body. Serious injury or death will occur if the unit’s body suddenly lowers and traps a part of your body.
DANGER
Do not raise a body that has refuse while you do maintenance or service procedures. Refuse in the body can make the
unit unstable. Always unload refuse from the body before you raise it for maintenance or service procedures. Always use
the body props when you raise the body for maintenance or service procedures.
DANGER
A full or partially full load of refuse is dangerous while you lower the body with inoperative controls. Refuse in the body can
make the unit unstable and cause it to overturn. Serious injury or death can occur if the unit overturns due to instability
caused by the loaded refuse. REMOVE the refuse before you block the body.
DANGER
Lifting equipment that does not have sufficient lifting capability is dangerous. Equipment can fail and cause death or
serious injury to the operator or bystanders. Make sure the lifting equipment has sufficient lifting capability and clear ALL
persons not involved with the procedure away from the area.
DANGER
The lifting equipment can fail. Serious injury or death can occur if the lifting equipment breaks and the body falls or the unit
rolls over. Do not place your body or limbs between the unit’s body and chassis while you remove the body-supporting
timbers. Be attentive and prepared to move quickly away from the unit in the event there is an equipment failure.
DANGER
Contact of the unit with overhead electric lines is dangerous. Death or serious injury can occur. Make sure there is
adequate overhead clearance before you raise the container. If the unit does make contact with overhead electric lines do
not touch any metal in the cab. Stay in the unit until help arrives..
WARNING
Make sure the unit is in the Lock-Out/Tag-Out mode when you do maintenance or service procedures, or when you go in
the hopper, climb in or on the body or on equipment. Equipment can be operated when the unit is not in the Lock-Out/Tag-
Out mode. When the unit is not in the Lock-Out/Tag-Out mode, equipment operated while you do maintenance or service
procedures, go in the hopper or climb in or on the body or on equipment can cause death or serious injury.
WARNING
Moving equipment can be dangerous to bystanders. Death or serious injury can occur if a person is in the wrong area or is
not attentive to the operations. Clear the area of all unnecessary people before you operate the controls.
WARNING
Raising the body with the tailgate closed can damage the underride bumper. The under ride bumper can hit the ground
when the tailgate is not fully raised before you raise the body. Death or serious injury can occur and also cause damage to
the unit.

WARNING
Clear all people of the area before you lift a refuse container. Make sure the refuse is secure in the refuse container before
you lift the container. Loose refuse can fall and cause death or serious injury.
WARNING
The hydraulic fluid can be under pressure and can spray while you open the connection. Hydraulic fluid can cause
damage to your eyes, hands or skin. Wear protective eye glasses, gloves and other clothing as necessary to protect you
from the hydraulic fluid.
WARNING
A unit that needs service or repair can malfunction and create a dangerous condition. A part failure during operation can
cause death or serious injury to a person or damage to the unit. Repair or replace any failed or defective part immediately
WARNING
Improper dumping of the refuse can cause the unit to tip or rollover. Death or serious injury can occur if the unit rolls or
tips over. Empty as much refuse as you can with the packer panel before you raise the body.
WARNING
Do not move the unit forward or backwards excessively fast (lurch) to dump the refuse load. Excessively fast movements
with the body raised can make the body unstable and tip or roll the unit over. This can result in death or serious injury to
the operator and damage the unit. Use only sufficient movement to loosen the load so that it will leave the body.
WARNING
Isopropyl alcohol is flammable and is harmful to eyes and skin. Keep isopropyl alcohol away from heat or open sources of
ignition. Flush eyes and skin with water for 15 minutes after contact. Seek immediate medical help.
WARNING
A container that is not locked to the container lift mechanism is dangerous. The container can fall off the container lift
mechanism and cause death or serious injury. Make sure you engage and lock the container latch bars before you lift the
container.
WARNING
Grabbing a refuse container with too much pressure can damage the container. Pieces of the container can “fly” off the
container and cause moderate or minor injury to a bystander. Use enough pressure with the grabber to raise the container
with the lift arm and not damage the container.
NOTICE
Do not move the unit forward or backwards excessively fast (lurch) to dump the refuse load. Excessively fast movements
with the body raised puts a very high load on the body raise cylinders and could damage one or both cylinders and make
the body unstable unable to lower. Inspect the cylinders after you dump each load and replace if necessary.
NOTICE
Do not operate the unit or perform repair or maintenance procedures on the unit until you read and understand the
instructions in this manual. Failure to do so can result in damage to the unit or other property. If you do not understand a
procedure or instruction, tell the owner or the designated person immediately. Do not operate the unit if you do not
understand all procedures and instructions in this manual. The owner or designated person can contact your Heil dealer or
Heil for additional help. See the Operator’s Manual or Service Manual for contact information.

NOTICE
Grabbing a refuse container with too much pressure can damage the container. The container can become unusable. Use
enough pressure with the grabber to raise the container with the lift arm and not damage the container.
NOTICE
Always use your employer’s Lock-Out/Tag-Out procedures. If your employer does not have Lock-Out/Tag-Out procedures,
use the procedures that follow. Contact your supervisor or ESG Technical Service if you have any questions about Lock-
Out/Tag-Out procedures.
NOTICE
You can order Lock-Out/Tag-Out Tags through your Heil Dealer or through Heil.
