GENERAL SAFETY INSTRUCTIONS and PRACTICES
A careful operator is the best operator. Safety is of primary importance to the manufacturer and should be to
the owner/operator. Most accidents can be avoided by being aware of your equipment, your surroundings, and
observing certain precautions. The first section of this manual includes a list of Safety Messages that, if
followed, will help protect the operator and bystanders from injury or death. Read and understand these Safety
Messages before assembling, operating or servicing this Implement. This equipment should only be operated
by those persons who have read the manual, who are responsible and trained, and who know how to do so
responsibly.
The Safety Alert Symbol combined with a Signal Word, as seen below, is used throughout this
manual and on decals which are attached to the equipment. The Safety Alert Symbol means:
“ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!” The Symbol and Signal
Word are intended to warn the owner/operator of impending hazards and the degree of
possible injury faced when operating this equipment.
Practice all usual and customary safe working precautions and above all---remember safety is up to
YOU. Only YOU can prevent serious injury or death from unsafe practices.
Indicates an imminently hazardous situation that, if not avoided, WILL result in DEATH OR
VERY SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, COULD result in DEATH OR
SERIOUS INJURY.
Indicates an imminently hazardous situation that, if not avoided, MAY result in MINOR
INJURY.
Identifies special instructions or procedures that, if not strictly observed, could result in
damage to, or destruction of the machine, attachments or the environment.
NOTE: Identifies points of particular interest for more efficient and convenient operation or repair. (SG-1) str
READ, UNDERSTAND, and FOLLOW the following Safety Messages. Death or serious
injury may occur unless care is taken to follow the warnings and instructions stated in the
Safety Messages. Always use good common sense to avoid hazards. (SG-2) str

SAFETY
AGR-BGR-BRGR 08/22 Safety Section 1-3
SAFETY
© 2022 Alamo Group Inc.
Operate this Equipment only with a Tractor equipped with an approved roll-over-
protective system (ROPS). Always wear seat belts. Death or serious injury could
result from falling off the tractor, particularly during a turnover when the operator
could be pinned under the ROPS. (SG-7) str
Never allow children to operate, ride on, or come close to the Tractor or
Implement. Usually, 16-17 year-old children who are mature and
responsible can operate the implement with adult supervision, if they have
read and understand the Operator’s Manuals, been trained in proper
operation of the tractor and Implement, and are physically large enough
to reach and operate the controls easily. (SG-11) str
Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in death or serious injury. (SG-10)str
Never allow children to play on or around Tractor or Implement. Children can slip or fall off
the Equipment and be killed or injured. Inadvertent contact with controls can cause the
Implement to shift or fall crushing themselves or others. (SG-25) str
DO NOT use drugs or alcohol immediately before or while operating the
Tractor and Implement. Drugs and alcohol will affect an operator’s
alertness and coordination and therefore affect the operator’s ability to
operate the equipment safely. Before operating the Tractor or Implement,
an operator on prescription or over-the-counter medication must consult
a medical professional regarding any side effects of the medication that
would hinder their ability to operate the Equipment safely. NEVER
knowingly allow anyone to operate this equipment when their alertness or
coordination is impaired. Serious injury or death to the operator or others
could result if the operator is under the influence of drugs or alcohol. (SG-
27) str
Never walk or work under any raised boom or bucket. The Boom could fall and cause serious
bodily injury or death. Always lower the boom and bucket flat on the ground or support the
Boom and bucket on safety stands. Unload all hydraulic actuators prior to performing any
maintenance. To do this, set the bucket on the ground then kill the tractor engine. Push and
pull the control levers in and out several times to remove pressure. Do not work under raised
Boom or Bucket unless components are securely blocked up to prevent inadvertent dropping.

OPERATOR SAFETY INSTRUCTIONS AND PRACTICES
Never operate the Tractor or Implement until you have read and
completely understand this Manual, the Tractor Operator’s Manual, and
each of the Safety Messages found in the Manual or on the Tractor and
Implement. Learn how to stop the tractor engine suddenly in an
emergency. Never allow inexperienced or untrained personnel to
operate the Tractor or Implement without supervision. Make sure the
operator has fully read and understood the manuals prior to operation.
(SG-4)str
The operator and all support personnel should wear hard hats, safety
shoes, safety glasses, and proper hearing protection at all times for
protection from injury including injury from items that may be thrown by the
equipment. (SG-16)str
PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE PERMANENT
HEARING LOSS! Tractors with or without an Implement attached can
often be noisy enough to cause permanent hearing loss. We recommend
that you always wear hearing protection if the noise in the Operator’s
position exceeds 80db. Noise over 85db over an extended period of time
will cause severe hearing loss. Noise over 90db adjacent to the Operator
over an extended period of time will cause permanent or total hearing loss.
NOTE: Hearing loss from loud noise [from tractors, chain saws, radios,
and other such sources close to the ear] is cumulative over a lifetime
without hope of natural recovery. (SG-I7)str
Always read carefully and comply fully with the manufacturer’s instructions
when handling oil, solvents, cleansers, and any other chemical agent. (SG-
22)str
Never run the Tractor engine in a closed building or without adequate ventilation. The
exhaust fumes can be hazardous to your health. (SG-23) str
Battery posts, terminals and related accessories contain lead and lead compounds and
chemicals known to the state of California to cause cancer, birth defects or other reproductive
harm. (SG-31)
Prolonged operation may cause operator boredom and fatigue affecting safe operation. Take
scheduled work breaks to help prevent these potentially impaired operating conditions.
Never operate the Implement and Tractor in a fatigued or bored mental state which impairs
proper and safe operation. (SG-32) str

SAFETY
AGR-BGR-BRGR 08/22 Safety Section 1-5
SAFETY
© 2022 Alamo Group Inc.
Use extreme caution when getting onto the Implement to perform repairs, maintenance and
when removing accumulated material. Only stand on solid flat surfaces to ensure good
footing. Use a ladder or raised stand to access high spots which cannot be reached from
ground level. Slipping and falling can cause serious injury or death. (SG-33) str
Use extreme care when loading, carrying or handling any agricultural
fertilizers, chemicals or biological residue. Follow the manufacturer’s
handling instructions and wear appropriate Personal Protective Equipment
including gloves, safety glasses and respirator when required. If you are
using a tractor equipped with a cab, make sure the cab is rated for
appropriate environmental exposure. Be safe and always wear proper
protection. Short or long term exposure to certain chemicals and materials
can result in serious injury or death. (SL-19) str
Repeated or substantial breathing of hazardous dusts, including crystalline
silica, could cause fatal or serious respiratory disease including silicosis.
Concrete, masonry, many types of rock, and various other materials contain
silica sand. California lists respirable crystalline silica as a substance
known to cause cancer. Operation of this equipment under certain
conditions may generate airborne dust particles that could contain
crystalline silica. In those conditions, personal protective equipment
including an appropriate respirator must be used. If excessive dust is
generated, a dust collection or suppression system should also be used
during operation. (SG-41) str
EQUIPMENT OPERATION SAFETY INSTRUCTIONS AND PRACTICES
This Implement may be wider than the Tractor. Be careful when operating or transporting this
equipment to prevent the Implement from running into or striking sign posts, guard rails,
concrete abutments or other solid objects. Such an impact could cause the Implement and
Tractor to pivot violently resulting in loss of steering control, death, or serious injury. Never
allow the Implement to contact obstacles. (S3PT-12)str
Never grasp control levers when mounting the machine. (SBH-4) str
The Boom is designed only to position and operate the Bucket which is attached to it. Never
attempt to lift, pull, or push other solid objects with the boom or bucket. Serious injury could
result from a structural failure when the Boom is used for purposes other than those for which
it was designed. (SBH-9) str
Operate this Implement only in conditions where you have clear visibility in daylight or with
adequate artificial lighting. Never operate in darkness or foggy conditions where you cannot
clearly see at least 100 yards in front and to the sides of the tractor and implement. Make sure
that you can clearly see and identify passersby, steep slopes, ditches, drop-offs, overhead
obstructions, power lines, debris and foreign objects. If you are unable to clearly see these
types of items discontinue operating this equipment. (S3PT-21) str

BEFORE leaving the tractor seat lower the implement, set the parking
brake and/or set the tractor transmission in parking gear, disengage the
PTO, stop the engine, remove the key, and wait for all moving parts to stop.
Place the tractor shift lever into a low range or parking gear to prevent the
tractor from rolling. Never dismount a Tractor that is moving or while the
engine is running. Operate the Tractor controls from the tractor seat only.
(SG-9)str
Do not mount or dismount the Tractor while the tractor is moving. Mount the
Tractor only when the Tractor and all moving parts are completely stopped.
Dismounting a moving power unit can result in a crushing hazard that can
cause death or serious injury. (SG-12) str
Start tractor only when properly seated in the Tractor seat. Starting a tractor in
gear can result in death or serious injury. Read the Tractor operators manual
for proper starting instructions. (SG-13) str
Operate the Tractor and/or Implement controls only while properly seated in the Tractor seat
with the seat belt securely fastened around you. Inadvertent movement of the Tractor or
Implement may cause death or serious injury. (SG-29)str
DO NOT operate this Implement on a Tractor that is not properly maintained. Should a
mechanical or Tractor control failure occur while operating, immediately shut down the
Tractor and perform repairs before resuming operation. Serious injury and possible death
could occur from not maintaining this Implement and Tractor in good operating condition. (SG-
36) str
Do Not operate this equipment in areas where insects such as bees, may attack you and/or
cause you to lose control of the equipment. If you must enter in such areas, use a tractor with
an enclosed Cab and close the windows to prevent insects from entering. If a tractor cab is
not available, wear suitable clothing including head, face, and hand protection to shield you
from the insects. Attacking insects can cause you to lose control of the tractor, which can
result in serious injury or death to you or bystanders. Never dismount a moving tractor. (SG-
40) str
Keep bystanders 10 feet away from the tractor and loader while
operating. The bystanders could enter the path of the tractor or items
could fall from the loader resulting in serious injury to the bystander. (SL-01
