Inspection Performed - Warranty and Safety Procedures Explained - Installation Complete
•I have informed the Purchaser of this product of Warranty terms, provisions, and procedures that are applicable, reviewed the contents of the Operator’s Manual
including safety equipment, safe operation, and maintenance, reviewed the Safety Signs on implement (and tractor if possible), and Purchaser’s responsibility to
train his operators in safe operation.
•IMPLEMENTS: I have explained that Deflectors, Chain Guards, or Solid Skirts must be maintained in good repair and installed except in areas where persons,
vehicles, livestock, or other property will not be endangered by thrown objects and where such safety equipment would prevent the mower’s reasonable performance
of its assigned task.
•DRIVELINES: I have made certain that all driveline, gearbox, and other shields are in good repair and fastened securely in place to prevent injuries from
entanglement or thrown objects.
•HYDRAULIC MACHINES: I have explained the necessity of using clean hydraulic oil, changing filters as instructed, stopping leaks, damage caused by
operating with over-heated oil, caring for hoses, using hoses of proper rating, the necessity of maintaining the specified operating pressure, and the potential hazard
of oil's penetrating the skin.
•BOOM-TYPE or FOLDING-TYPE IMPLEMENTS: I have explained that it is not possible to guard against thrown objects when the head is lifted off ground
and that operator is responsible to watch out for persons in the area. I have explained that the lifted mower head or boom can contact overhead obstructions with
damage to cables and telephone lines and possible injury. I have explained that the extended head or boom or retracted boom can contact power lines with resulting
electrocution injury or death and that operator is responsible for keeping clear of such hazards.

PELIGRO! ¡LEA EL
INSTRUCTIVO!
DANGER! 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 too operate the Tractor and Implement without supervi-
sion. Make sure the operator has fully read and understood the
manuals prior to operation. (SG-4)
WARNING! Always maintain the safety decals in good readable condition. If the
decals are missing, damaged, or unreadable, obtain and install replace-
ment decals immediately. (SG-5)
WARNING! Make certain that the “Slow Moving Vehicle” (SMV) sign is installed in
such a way as to be clearly visible and legible. When transporting the
Equipment use the Tractor flashing warning lights and follow all local
traffic regulations. (SG-6)
WARNING! Operate this Equipment only with a Tractor equipped with an ap-
proved roll-over-protective system (ROPS). Always wear seat belts.
Serious injury or even death could result from falling off the tractor-
-particularly during a turnover when the operator could be pinned
under the ROPS. (SG-7)
WARNING! Do not modify or alter this Implement. Do not permit anyone to
modify or alter this Implement, any of its components or any Imple-
ment function. (SG-8)
DANGER! BEFORE leaving the tractor seat, always engage the 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)
DANGER! Never allow children or other persons to ride on the Tractor or Implement.
Falling off can result in serious injury or death.
(SG-10)

SAFETY
DANGER! Never allow children to operate or ride on the Tractor or Implement.
(SG-11)
WARNING! Do not mount the Tractor while the tractor is moving. Mount the
Tractor only when the Tractor and all moving parts are completely
stopped. (SG-
12)
DANGER! Start tractor only when properly seated in the Tractor seat. Starting a
tractor in gear can result in injury or death. Read the Tractor operators
manual for proper starting instructions. (SG-13)
DANGER! Never work under the Implement, the framework, or any lifted
component unless the Implement is securely supported or blocked
up to prevent sudden or inadvertent falling which could cause serious
injury or even death. (SG-14)
DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is
expensive and its presence could present a hazard. Do not check for
leaks with your hand! Use a piece of heavy paper or cardboard.
High-pressure oil streams from breaks in the line could penetrate the
skin and cause tissue damage including gangrene. If oil does
penetrate the skin, have the injury treated immediately by a physician
knowledgeable and skilled in this procedure. (SG-15)
WARNING! 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 thrown by the
equipment. (SG-16)

Safety Section 1-5
SAFETY
HYDRO 88 & 96 03/94
© 2003 Alamo Group Inc.
SAFETY
CAUTION! 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)
WARNING! Transport only at safe speeds. Serious accidents and injuries can result
from operating this equipment at unsafe speeds. Understand the Tractor
and Implement and how it handles before transporting on streets and
highways. Make sure the Tractor steering and brakes are in good
condition and operate properly.
Before transporting the Tractor and Implement, determine the safe
transport speeds for you and the equipment. Make sure you abide by
the following rules:
Be aware of the operating conditions. Do not operate the Tractor with
weak or faulty brakes. When operating down a hill or on wet or rain slick
roads, the braking distance increases: use extreme care and reduce
your speed. When operating in traffic always use the Tractor’s flashing
warning lights and reduce your speed. Be aware of traffic around you
andwatch out for the other guy. (SG-19)
Test the equipment at a slow speed in turns. Increase the speed
through the turn only after you determine that it is safe to operate
at a higher speed. Use extreme care and reduce your speed when
turning sharply to prevent the tractor and implement from turning
over. Determine the maximum safe turning speed for you and this
equipment before operating on roads or uneven ground.
Only transport the Tractor and Implement at the speeds that you
have determined are safe and which allow you to properly control the
equipment.
Test the tractor at a slow speed and increase the speed slowly.
Apply the Brakes smoothly to determine the stopping
characteristics of the Tractor and Implement.
As you increase the speed of the Tractor the stopping distance
increases. Determine the maximum safe transport speed for
you and this Equipment.

SAFETY
WARNING! Periodically inspect all moving parts for wear and replace when
necessary with authorized service parts. Look for loose fasteners,
worn or broken parts, and leaky or loose fittings. Make sure all pins
have cotter pins and washers. Serious injury may occur from not
maintaining this machine in good working order. (SG-21)
WARNING! Always read carefully and comply fully with the manufacturers instructions
when handling oil, solvents, cleansers, and any other chemical agent.
(SG-22)
DANGER! Never run the tractor engine in a closed building or without adequate
ventilation. The exhaust fumes can be hazardous to your health.
(SG-23)
DANGER! KEEP AWAY FROM ROTATING ELEMENTS to prevent entanglement
and possible serious injury or death. (SG-24)
DANGER! Never allow children to play on or around Tractor or Implement. Children
can slip or fall off the Equipment and be injured or killed. Children can
cause the Implement to shift or fall crushing themselves or others. (SG-25)
WARNING! Do not exceed the rated PTO speed for the Implement. Excessive PTO
speeds can cause Implement driveline or blade failures resulting in
serious injury or death. (SG-26)
DANGER! NEVER 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)

Safety Section 1-7
SAFETY
HYDRO 88 & 96 03/94

SAFETY
DANGER! 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
serious injury or death. (SG-29)
WARNING! Mow only in conditions where you have clear visibility in daylight or with
adequate artificial lighting. Never mow in darkness or foggy conditions
where you cannot clearly see at least 100 yards in front and to the sides
of the tractor and mower. 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
this type of items discontinue mowing. (SGM-1)
WARNING! 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)
WARNING! 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
gound level. Slipping and falling can cause serious injury or death.
(SG-33)
WARNING! Avoid contact with hot surfaces including hydraulic oil tanks, pumps,
motors, valves and hose connections. Relieve hydraulic pressure
before performing maintenance or repairs. Use gloves and eye
protection when servicing hot components. Contact with a hot
surface or fluid can cause serious injury from burns or scalding.
(SG-34)
WARNING! Perform service, repairs and lubrication according to the maintenance
section. Ensure the unit is properly lubricated as specified in the
lubrication schedule and all bolts and nuts are properly torqued.
Failure to properly service, repair and maintain this Implement in good
operating condition could cause component failure and possible
serious injury or even death. (SG-35)
DANGER! 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)
WARNING! Use caution and wear protective gloves when handling sharp objects
such as blades, knives, and other cutting edges. Be alert to worn
component surfaces which have sharp edges. Sharp surfaces can
inflict severe laceration injuries if proper hand protection is not worn.
(SG-37)

Safety Section 1-8
SAFETY
HYDRO 88 & 96 03/94

SAFETY
WARNING! Mow at the speed that you can safely operate and control the tractor and
mower. Safe mowing speed depends on terrain condition and grass
type, density, and height of cut. Normal ground speed range is from 0
to 5 mph. Use slow mowing speeds when operating on or near steep
slopes, ditches, drop-offs, overhead obstructions, power lines, or when
debris and foreign objects are to be avoided. (SGM-7)
WARNING! Avoid mowing in reverse direction when possible. Check to make sure
there are no persons behind the mower and use extreme care when
mowing in reverse. Mow only at a slow ground speed where you can
safely operate and control the tractor and mower. Never mow an area
that you have not inspected and removed debris or foreign material.
(SGM-8)
DANGER! Replace bent or broken blade with new blades. NEVER ATTEMPT
TO STRAIGHTEN OR WELD ON BLADES SINCE THIS WILL
LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE WITH
SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM
THROWN BLADES. (SGM-10)
WARNING! Do not mow with two machines in the same area except with Cab tractors
with the windows closed. (SGM-11)
DANGER! The rotating parts of this machine have been designed and tested for
rugged use. However, the blades could fail upon impact with heavy,
solid objects such as metal guard rails and concrete structures.
Such impact could cause the broken objects to be thrown outward
at very high velocities. To reduce the possibility of property damage,
serious injury, or even death, never allow the cutting blades to
contact such obstacles. (SGM-4)
WARNING! Extreme care should be taken when operating near loose objects
such as gravel, rocks, wire, and other debris. Inspect the area
before mowing. Foreign objects should be removed from the site to
prevent machine damage and/or bodily injury or even death. Any
objects that cannot be removed must be clearly marked and care-
fully avoided by the operator. Stop mowing immediately if blades
strike a foreign object. Repair all damage and make certain rotor or
blade carrier is balanced before resuming mowing. (SGM-5)
WARNING! Many varied objects, such as wire, cable, rope, or chains, can become
entangled in the operating parts of the mower head. These items could
then swing outside the housing at greater velocities than the blades.
Such a situation is extremely hazardous and could result in serious injury
or even death. Inspect the cutting area for such objects before mowing.
Remove any like object from the site. Never allow the cutting blades to
contact such items. (SGM-6)

SAFETY
DANGER! Always disconnect the main PTO Driveline from the Tractor before
performing service on the Mower. Never work on the Mower with the
tractor PTO driveline connected and running. Blades or Drivelines could
turn without warning and cause immediate entanglement, injury or
death. (SRM-3)
Follow these guidelines to reduce the risk of equipment and grass fires
while operating, servicing, and repairing the Mower and Tractor:
-Equip the Tractor with a fire extinguisher in an accessible location.
-Do Not operate the Mower on a Tractor with an underframe exhaust.
-Do Not smoke or have an open flame near the Mower and Tractor.
-Do Not drive into burning debris or freshly burnt areas.
-Ensure slip clutches are properly adjusted to prevent excessive slippage
and plate heating.
-Never allow clippings or debris to collect near drivelines, slip clutches,
and gearboxes. Periodically shut down the Tractor and Mower and clean
clippings and collected debris from the mower deck. (SGM-12)
WARNING!
WARNING! DO NOT weld or repair rotating mower components. Welds and other
repairs may cause severe vibration and/or component failure resulting
in parts being thrown from the mower causing serious bodily injury.
See your Authorized Dealer for proper repairs. (SGM-13)
DANGER! The Mower is designed for certain mowing applications and is rated to
cut up to a specific size vegetation (see Mower Standard Equipment
and Specifications). DO NOT use this Mower to cut vegetation above
the Mower’s rated capacity or to cut any type of non-vegetative
material. Only operate this Mower on a properly sized and equipped
Tractor. Operating this Mower in an application for which it is not
designed and/or operating the Mower with the wrong size Tractor can
cause Mower component damage and equipment failure resulting in
possible serious injury or death. (SGM-14)
WARNING! Do not let the Blades turn when the Mower Deck is raised for any
reason, including clearance or for turning. Raising the Mower
deck exposes the Cutting Blades which creates a potentially
serious hazard and could cause serious injury or even death from
objects thrown from the Blades. (SRM-7)

SAFETY
WARNING! Do not operate Mower if excessive vibration exists. Shut down PTO
and the Tractor engine. Inspect the Mower to determine the source
of the vibration. If Mower blades are missing or damaged replace
them immediately. Do not operate the mower until the blades have
been replaced and the Mower operates smoothly. Operating the
Mower with excessive vibration can result in component failure and
broken objects to be thrown outward at very high velocities. To
reduce the possibility of property damage, serious injury, or even
death, never allow the Mower to be operated with blades missing.
(SFL-4)
DANGER! All Safety Shields, Guards and Safety devices including
(but not limited to) - the Deflectors, Steel Guards,
Gearbox Shields, PTO integral shields , and Retractable
Door Shields should be used and maintained in good
working condition. All safety devices should be inspected
carefully at least daily for missing or broken components.
Missing, broken, or worn items must be replaced at
once to reduce the possibility of injury or death from
thrown objects, entanglement, or blade contact. (SFL-5)
DANGER! Do not put hands or feet under mower decks. Blade Contact can result
in serious injury or even death. Stay away until all motion has stopped
and the decks are securely blocked up. (SFL-2)
DANGER! There are obvious and hidden potential hazards in the operation of this
Mower. REMEMBER! This machine is often operated in grass and
in heavy weeds. The Blades of this Mower can throw objects if shields
are not properly installed and maintained. Serious injury or even
death may occur unless care is taken to insure the safety of the
operator, bystanders, or passersby in the area. Do not operate this
machine with anyone in the immediate area. Stop mowing if anyone
is within 100 yards of mower. (SFL-1)
WARNING! Only tow the Implement behind a properly sized and equipped Tractor
which exceeds the weight of the Implement by at least 20%. DO NOT
tow the Implement behind a truck or other type of vehicle. Never tow the
Implement and another Implement connected in tandem. Never tow the
Implement at speeds over 20 MPH. (STI-6)
