OPERATION
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 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.
SAFETY PRECAUTIONS
SAFETY PRECAUTIONSSAFETY PRECAUTIONS
SAFETY PRECAUTIONS
For better stability, always use a tractor equipped with a wide front axle, never use a tractor equipped
with a tricycle type front axle.
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.
OPERATION
OPERATIONOPERATION
OPERATION
▶
▶ 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.
▶
▶ 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.
▶
▶
▶
▶ 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.
▶
▶
Add wheel ballast and/or rear weight to counterbalance tractor/loader for stability at maximum loader
capacity.
Avoid driving over loose fill, rocks, holes, or anything that may be dangerous for loader operation or
movement.
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.
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.

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.
Operate controls only when seated in
the operator s seat.
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.

WARNING:
By "feathering" the control lever, reduced

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.
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".
Contact with overhead power lines can cause
severe electrical burns or death from
electrocution. Make sure there is clearance
between raised equipment and over head
power lines.
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.
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.
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.
Observe the following safety warning when
transporting a loaded bucket.

Contaminates in hydraulic oil can cause valve spools to stick. Be alert when operating loader and
follow your Tractor Operator s Manual maintenance schedule.
The loader hydraulic valve lift Cylinder circuit incorporates a "float" position which allows the
loader bucket to follow ground contours. The "float" position is engaged by shifting the control
lever forward into "detent" until the operator pulls the control lever out of the "Detent" position.
