SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
PREPERATION
▶Move the wheels to the tractor manufacturer's widest recommended settings to increase stability.
▶For better stability, always use a tractor equipped with a wide front axle, never use a tractor equipped
with a tricycle type front axle.
▶Add rear ballast or rear weight to the tractor to compensate for the load and increase stability.
▶Add recommended rear tire liquid weight or rear wheel weights for increased stability.
▶Do not modify, alter, or permit anyone else to modify or alter the loader, any of its components, or
any loader function without first consulting a LS Mtron dealer.
▶Assemble, remove, and reinstall the loader only as directed in this manual. Failure to do this could
result in serious personal injury or death.
▶The loader may shift during shipping and handling, making it unstable on the pallet. Support loader
with an overhead hoist or other suitable means prior to removing bands or attaching straps securing
loader to pallet. Failure do so could result in accidental tip-over of the loader that could cause serious
injury to you and/or bystanders.
BEFORE OPERATION
▶Before starting the engine of your tractor, make sure all operating controls are in park lock or neutral
position.
▶Be certain lights and safety markings, as provided by the tractor manufacturer, are clean and operating
when transporting the tractor/loader on public roads. Be certain that the Slow Moving Vehicle (SMV)
emblem is visible. Check with local law enforcement for specific requirements.
OPERATION
▶Add wheel ballast and/or rear weight to counterbalance tractor/loader for stability at maximum loader
capacity.
▶Additional counterweight requirements will vary with loader attachments and equipment application.
▶Move and turn the tractor at low speeds.
▶Carry loader boom at a low position during normal operation.
▶Never travel at high speeds with bucket loaded.
▶Use caution when operating the loader with a raised bucket or attachment.
▶Avoid driving over loose fill, rocks, holes, or anything that may be dangerous for loader operation or
movement.
▶Allow for the loader length when making turns.
▶Use caution when handing loose or unstable loads.
▶Gradually stop the loader boom when lowering or lifting loads.
▶When using remote hydraulic tractor valves on some tractors, the loader lift and dump cylinders will
continue moving unless the valve handle/handles are manually returned to neutral, or until relief
pressure is reached at the ends of piston strokes. Observe the bucket movement and maintain control
with valve handle/handles.
▶Travel speed should be such that complete control and machine stability is maintained at all times.
Where possible, avoid operating near ditches, embankments, and holes. Reduce speed when turning,
crossing slopes, and on rough, slick or muddy surfaces.
▶A loader attachment should be transported in a low position at slow ground speeds. Make turns
slowly and use the tractor brakes cautiously. A loaded attachment in the raised position alters the
center of gravity location of the machine and increases the possibility of mishaps.
▶Be careful during loading, transporting, and stacking to minimize rolling bales and tractor tip over.
▶Do not use buckets, forks, or other attachments without bale retaining devices.
▶Operate the tractor and loader such that complete control and machine stability is maintained at all
times.
▶When using a loader, be alert of bucket or attachment position at all times. Loader in raised position
with bucket or attachment rolled back can dump material onto tractor causing damage or injury to
tractor and/or operator.

SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
LARGE HEAVY OBJECTS
▶Never use loader for handling large heavy objects, such as large round or rectangular bales, logs, and
oil drums unless loader is equipped with attachment that is designed to handle such objects.
▶Handling large heavy objects can be extremely dangerous due to danger of rolling the tractor over.
▶Handling large heavy objects can be extremely dangerous due to danger of upending the tractor.
▶Handling large heavy objects can be extremely dangerous due to danger of the object rolling or
sliding down the loader boom onto the operator.
▶If you must handle large heavy objects, protect yourself by using caution, moving slowly, and avoiding
bumps and rough ground.
▶If you must handle large heavy objects, protect yourself by never lifting load higher than necessary to
clear the ground.
▶If you must handle large heavy objects, protect yourself by adding rear ballast to the tractor to
compensate for weight of load.
▶If you must handle large heavy objects, protect yourself by never lifting large heavy objects that may
roll or fall on the operator.
▶Never lift any load from any point of the loader with a chain, rope or cable unless loader is equipped
with a Factory approved attachment that was designed and built for this type of lifting. Always follow
lifting instructions included with these attachments.
▶Use only Factory bale probe or bale retaining devise handler attachment when handling round bales.
▶Do not handle large square bales without a retaining device handler attachment.
▶Do not use buckets, forks, or other attachments without bale retaining devices.
▶Do not use loader for handling large, heavy objects such as logs, tanks, etc.
SLOPES
▶Stay off of slopes too steep for safe operation.
▶Shift down before you start up or down a hill with a heavy load. Avoid "freewheeling".
▶Use extreme caution when operating on a slope.
▶Always operate up and down the slope, never across the slope.
ELECTRICAL
▶Avoid contact with overhead wires, power lines, and obstacles when loader bucket or attachment is
raised.
▶Electrocution from power lines can occur with or without contact.
▶Check for underground utilities before digging below grade level.
▶Contact with overhead power lines can cause severe electrical burns or death from electrocution. Make
sure there is enough clearance between raised equipment and overhead power lines.
HYDRAULIC
▶Do not tamper with the relief valve setting. This will void warranty and could cause damage to loader
and/or tractor.
▶Pouring hydraulic fluid under pressure can have sufficient force to penetrate the skin, causing serious
personal injury. Do not use HANDS to search for suspected leaks. If injured by escaping fluid, obtain
medical treatment immediately.
▶Visually check for hydraulic leaks and broken, missing or malfunctioning parts. Never use your hand to
check for suspected leaks under pressure. Use a piece of cardboard or wood for this purpose. Escaping
hydraulic fluid or diesel fuel leaking under pressure can have sufficient force to penetrate the skin and
cause serious infection or other personal injury. If injured by leaking fluid, seek medical attention
immediately.
▶To prevent personal injury, relieve all pressure before disconnecting fluid lines.
▶Before applying hydraulic pressure, make sure all hydraulic connections are tight and components are
in good condition.
▶Be sure to purge all the air from the hydraulic system before attempting to raise or lower this machine.

SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
▶When using remote hydraulic tractor valves on some tractors, the loader lift and dump cylinders will
continue moving unless the valve handle/handles are manually returned to neutral, or until relief
pressure is reached at the ends of piston strokes. Observe the bucket or attachment movement and
maintain control with valve handle/handles.
▶Raised loader or boom can fall due to hydraulic system failure.
▶To avoid serious injury or death: Block up or securely support loader and boom before working
underneath.
▶To avoid serious injury or death: Purge all air from hydraulic system before attempting to raise or
lower loader or boom.
▶To avoid serious injury or death: Stand clear if lowering or raising loader or boom.

immediately.
▶Lower the loader or boom and release hydraulic pressure before loosening fittings.
AFTER OPERATION
▶ Before leaving the tractor seat, lower attachment or loader boom to ground, stop engine, lock parking
brakes, put all controls in neutral, relieve hydraulic pressure, and remove key before leaving operator's
seat.
▶ Before disconnecting hydraulic lines, relieve all hydraulic pressure.
▶ Make sure all parked loaders on stands are on a hard level surface with all safety devices engaged to
prevent loader from falling and being damaged or injuring someone.
▶ Always park loader with bucket attached to loader.
▶ When a front loader is mounted on the tractor, enter and exit the operator's seat only from left side of
the tractor.
▶ Always park loader with a Factory attachment attached to the loader.
▶ Special care should be taken to park or store attachments with points or sharp edges in a safe manner.
▶ Make sure all parked loaders are on a hard level surface. Engage all safety devices to prevent loader
from falling and being damaged or injuring someone. Do not repair loader if it is not mounted on the
tractor. Loss of hydraulic fluid or removal of parts could cause loader to collapse resulting in injury.
REPAIR
▶ Visually check for hydraulic leaks and broken, missing, or malfunctioning parts. Make necessary repairs
before operation.
▶ To keep mounting kit hardware from loosening during loader operation, hardware must be torqued to
specifications notes in operator manual.
▶ Always wear safety goggles when servicing or repairing the machine.
▶ When servicing or replacing pins in cylinder ends, bucket, etc., always use a brass drift and hammer.
Failure to do so could result in injury from flying metal fragments.

TRACTOR PREPARATION
Rear Counterweight
CAUTION:
Add recommended rear tire liquid
weight, rear wheel or rear ballast for
increased stability.
CAUTION:
Do not exceed the manufacturer's
rating for maximum gross vehicle weight.
Refer to Operator's Manual or ROPS serial
plate provided with tractor.
CAUTION:
Certain specific conditions may not
permit safe use of loader at loader rating or
may require more careful restricted operation
at the rated load.
Refer to Tractor Operator's Manual for specific
recommendations on counterweight tractor.
▶ROPS System
The tractor must be equipped with an approved
ROPS System to ensure adequate operator's
protection
The use of adequate counterweight to counter
balance for maximum loader capacity is required for
safe loader operation.
Weight added to rear of the tractor provides better
traction and easier, more efficient loader operation.
The tractor can be counter weighted by filling rear
tires with liquid calcium solution and/or by the
installation of rear wheel weights.
Additional counterweight requirements will vary with
loader attachments and equipment applications.
Additional weight can be added by installation of
Three Point Hitch mounted ballast.
▶Tractor Hydraulic System
Tractor operation in a loader application significantly
increase demands on the tractor Hydraulic System.
Check the tractor Hydraulic system fluid level daily.
Refer to your tractor Operator's Manual maintenance
section for instructions regarding tractor hydraulic
system maintenance.
Adhere to recommendation in your Tractor
Operator's Manual concerning hydraulic fluid and
filter specifications, and change intervals.
CAUTION:
The tractor/loader must only be operated with all safety equipment properly installed.
▶TRACTOR TIRES
Selection of tires(size, profile, tread type) should be
restricted to tire recommendations as specified by LS
Mtron
▶Tire Inflation
Front tires must be maintained at the maximum
recommended inflation to maintain normal tire
profile with the added weight of loader/material.
Rear tires must be maintained at equal pressure
within the recommended tire inflation range.
Unequal rear tire inflation can prevent loader
attachment from contacting the ground across its
full width.
▶Wheel Tread Settings
Tractor front wheel tread setting must be restricted
to wheel tread spacing recommended in the tractor
Operator's Manual.
▶Front Counterweight
Use of front counterweight is not recommended
when tractor is being used in a loader application.
Front counterweight adds unnecessary front axle
load in loader applications.

LOADER OPERATION
CAUTION:
The tractor/loader should only be operated
with all safety equipment properly installed.
▶Precautionary Notes
Do not lower the edge of the bucket too low for
loading. Keep the bottom of the bucket level with
the ground when loading.
▶Important:
Do not use the bucket for pushing down material
with bucket cylinders partially extended. Damage to
the cylinders may result.
▶Important:
Do not operate bucket cylinders without bucket, it
may damage to the bucket cylinders.
▶Important:
Do not tip bucket cutting edge down(fully extended
bucket cylinders) during backfilling/backgrading
operations.
▶Important:
Operation with front tractor wheels off the ground is
not recommended.
Position vehicle to be loaded as near the pile as
possible and in such a direction as to minimize the
amount of tractor turning required dumping.
Do not lower the loader with the tractor engine shut
off.
Keep the unit clean and perform regular service.
Observe safety messages whenever cleaning,
servicing, or lubricating.
We urge you to follow this advice:
1. Read and understand this manual as well as the
Tractor Operator's Manual.
2. Remember and observe the Safety Precautions
brought to your attention in this manual, the tractor
manual and on the machinery itself.
3. Use good common sense in the everyday
operation of this unit.
Safety recommendations can never be all-inclusive
and you are responsible for watching out for and
avoiding unsafe conditions.
4. Never exceed the limits of a piece of machinery. If
its ability to do a job or to do so safely is in
question, don't try it.
5. Don't hurry the learning process or take the unit
for granted. Ease into it and become familiar with
your new loader and tractor.
CAUTION: When lowering a heavy load, ease
it downward slowly. Never drop a loaded
attachment and "catch it hydraulically".
Stopping a load after it has gained downward
momentum places undue strain on the unit and may
cause unnecessary damage to the loader or tractor
or even worse, personal injury.
CAUTION: Before disconnecting hydraulic
lines, relieve all hydraulic pressure. Escaping
hydraulic oil under pressure can have
sufficient force to penetrate the skin causing serious
personal injury. If injured by escaping hydraulic oil
seek medical attention immediately.
CAUTION: Do not operate the loader if the
fittings are leaking or if the hoses are
damaged. A sudden line burst would cause
the mainframe to drop suddenly, causing damage to
the tractor or loader or injury to personnel.
▶Initial Loader Operation
Before operating the loader, fully raise and lower the
boom two or three times. Then raise the bucket
approximately four(4) feet above the ground and
cycle the bucket cylinders three times. Lower the
bucket to the ground. Check the tractor hydraulic oil
and the correct oil level.
CAUTION:
Before leaving the machine, stop the engine, remove
the key, place all controls in neutral, and either set
the parking brake or place tractor in park as
equipped.
Always keep cylinders in a retracted position when
the loader is not in use to guard against rust and
contamination which may cause damage to the
cylinder rods or hydraulic system.
▶Cold Weather Operation
For smooth operation in cold weather, let the tractor
warm up. Slowly cycle the lift and bucket cylinders
several times to warm the oil in the hydraulic system.
The loader may operate erratically until the hydraulic
oil has warmed to operating temperatures.

LOADER OPERATION
CAUTION:
Operate controls only when seated in the
operator's seat.
▶Loading Bucket
For the most efficient loading, slowly drive the
tractor straight into the material to be loaded and
increase speed only after contact has been made.
Roll the attachment back a small amount and slowly
lift to break away the material. As the load increase,
continue rolling the attachment back so as to get
the maximum load. Remove the top levels first when
loading from large piles of material. When bucket is
full, raise loader so the bucket is clear of material
and slowly back out of the pile.
▶Dumping Bucket
When in the dump area slowly drive the tractor
forward and raise the loader at the same time. Raise
the loader to the height needed to dump the bucket.
Make sure to keep a level bucket position to prevent
spilling from the bucket. Dump the bucket, and keep
all movements smooth.
▶Transporting a Loaded Bucket
Transport material with the bucket as low as possible
to prevent spilling and keep maximum stability. The
loader must be in a position that will not block the
operators' vision. A loaded bucket must not be
transported in the upright position or at excessive
speed.
Observe the following safety warning when
transporting a loaded bucket.
CAUTION:
When using a loader, be aware of bucket location at
all times. When raising a loader with bucket rolled
back, material can dump onto tractor causing
damage to tractor or injury to operator.
WARNING:
Contact with overhead power lines can cause severe
electrical burns or death from electrocution. Make
sure there is clearance between raised equipment
and overhead power lines.
CAUTION:
Stop the loader arms gradually when
lowering or lifting.
WARNING:
A loaded Bucket should be transported in a low
position at low ground speeds. Make turns slowly
and use the tractor brakes cautiously. A full bucket in
the raised position alters the center of gravity
location of the machine and increases the possibility
of accidents.
CAUTION:
Do not stand, walk or work under a raised loader
unless it is securely blocked or held in position.
Accidental movement of a control lever or leak in th
hydraulic system could cause the loader to drop, or
attachment to dump, resulting in serious injury or
death.
▶Scraping
When scraping, the Boom lever must be used to
keep the bucket on the ground horizontally. The
bucket must be kept level to the ground during
scraping operations.
▶Backfilling/Backgrading
When "Backfilling" or "Backgrading", position the
bucket so it is level on the ground. Do not dump
material from bucket following each pass, as
additional weight of material in bucket will assist in
"Backgrading" and increases loader efficiency during
"Backfilling".
▶Controlled Rate of Loader Functions
By "feathering" the control lever, reduced operational
speeds can be controlled. This action controls the
position of the valve spool in the valve body and
regulates flow of oil to/from cylinders. It is important
utilize this operational practice when lowering loader
boom when the bucket is loaded with material.

LOADER REMOVAL
CAUTION:
Never park loader without bucket attached
to the loader.
CAUTION:
Never allow weight of tractor to be put on
parking leg when removing loader.
▶Park the tractor and loader on hard level surface.
▶Raise the boom until the bucket is about 2 feet
off the ground.
▶Remove the Pin and R-pin from „K‟.
Open the Stand „X‟ by the Bracket „Y‟.
Assembly the Pin and R-pin at the „L‟
▶Lower the boom until the Parking legs make
contact on the ground.
Tip the bucket until the bucket cutting edge touch
the ground.
▶Remove the latch pin while move the control lever
back and forth slightly to make the latch pin easy.
▶Pull the control lever to raise the loader until the
post lift off mounting frame.
Adjust the bucket until the bottom surface of bucket
touch the ground.
▶Move the tractor backward slowly and stop to
avoid the hydraulic hoses being tighten.
▶Stop the engine and move the control lever back
and forth, left and right several times to reduce the
hydraulic pressure in the hoses.
▶Disconnect the quick couplers on the hydraulic
hoses.

LOADER MOUNTING
CAUTION:
Never allow weight of tractor to be put on parking
leg when mounting loader.
▶Carefully drive the tractor into the loader to a
position where the hydraulic hoses(Quick coupler)
can be connected to the control valve block.
▶Stop the engine and move the control lever back
and forth, Left and right several times to reduce the
pressure in the hydraulic hoses. Connect the
hydraulic couplers match the color code rings.
▶Start the engine and move the boom and bucket
to adjust the height of post.
Be sure to check the pin welded of post is slightly
higher than the hook on mounting frame.
▶Move the tractor forward to put the post into the
mounting frame. Stop the tractor
When the hook is right over the pin.
Lower the mounting frame with moving the boom
and bucket until it hooked securely each other.
▶Align the latch pin holes with moving the bucket
and boom.
Insert the latch pins.
Rubber hammer can be used to put the pin in if
needed.
▶Remove pin and keeper holding the parking legs
and return to storage position. Make secure by using
pin and keeper.

LUBRICATION AND MAINTERNANCE
CAUTION:
Do not perform and service or maintenance
Operations with loader raised off the ground. For
additional access to tractor components remove
loader.
▶Important:
Lower the loader to the ground and relieve pressure
in loader hydraulic lines prior to performing any
service or maintenance operations on the tractor or
loader.
CAUTION:
Escaping fluid under pressure can have sufficient
force to penetrate the skin, causing serious injury.
Before disconnecting lines, be sure to relieve all
pressure. Before applying pressure to the system, be
sure all connections are tight and that lines, pipes
and hoses are not damaged. Fluid escaping from a
very small hole can be almost invisible. Use a piece
of cardboard or wood rather than your hands to
search for suspected leaks. If injured by escaping
fluid, seek medical attention immediately. Serious
infection or reaction can develop if correct medical
treatment is not administered immediately.
Refer to "Lubrication and Maintenance Chart" for
quick reference to Maintenance Operations.
CAUTION:
Do not operate the loader if the fittings are leaking
or if the hoses are damaged. A sudden line burst
could cause the mainframe to drop suddenly,
causing damage to the tractor or loader or injury to
personnel.
CAUTION:
Operate the loader from the tractor seat only.
CAUTION:
Do not stand or walk under a raised loader.
Accidental movement of control lever or leak in
hydraulic system could cause mainframe to drop,
causing severe injury.
Check the tractor hydraulic system as outlined in the
Tractor Operator's Manual.
Note:
When checking hydraulic system oil level, the loader
should be on the ground and bucket fully
retracted(all cylinders in retracted position).
Grease all loader pivot points daily(10 hours). Refer
to Tractor Operator's Manual for lubricant
recommendations.
Inspect hydraulic hoses, connections, control valve
and cylinders for evidence of leakage.
Tractor tires should be maintained at maximum
recommended inflation to maintain normal tire
profile with added weight of loader/material.
Unequal rear tire inflation can result in bucket not
being level to the ground.
