Raising hydraulic pressure on this
machine above the factory approved
settings may cause death, severe
injury or property damage and will
void the warranty
The consequences of increasing hydraulic pressure are
serious. The function of the relief valves are to provide a
fuse action to protect the machine and the operator from
overloading. When overloaded, the machine can become
stressed to a level where part fractures cause death, se-
vere injury or property damage. This is an extremely
dangerous practice.
Accordingly, you are advised that the pressure settings of
this machine are limited to the factory approved settings.
Pressures in excess of these settings render each and all
Barko warranties null and void and constitute an obvious
misuse and abuse of our product.

KNOW YOUR MACHINE
The following is a list of ten important safety precautions and warnings you should read through and understand
before operating or servicing your machine.
1. Don't assume that because you know the control functions of other similar machinery, that you can run and/
or service the Barko Loader. All machines differ in some ways, and these differences must be noted and
acknowledged. Read this manual thoroughly and understand all safety, operating, and servicing procedures
before using the loader.
2. Know how to put your machine in a zero energy state for purposes of inspection, maintenance, or repair.
3. Clear operating area of all obstacles and personnel before operating loader.
4. Never approach power lines with any part of the machine or load! Current in a high voltage power line may arc
some distance to jump from the wire to a nearby "ground". KEEP WELL CLEAR!
5. Allow only the operator on the machine. Keep riders off. Riders on machine are subject to injury such as being
struck by foreign objects and being thrown off the machine. Riders also obstruct the operator's view, resulting in
the machine being operated in an unsafe manner.
6. Never use a boom or attachment for a work platform or personnel carrier. Serious injury or death may result.
7. When machine is not operating or when leaving cab, boom and attachment must be lowered to the ground.
Failure to do so may allow boom or attachment to move, causing property damage, injury, or death.
8. Donottamperwithanyhydrauliclinewhenitispressurized.Escapinguidunderpressurecanpenetratethe
skin, causing serious injury. Relieve pressure before unhooking hydraulic or other lines. Tighten all connections
beforeapplyingpressure.Keephandsandbodyawayfrompinholesandnozzleswhichejectuidsunderhigh
pressure. Use a piece of cardboard to search for leaks.
 Ifanyuidisinjectedintotheskin,itmustbesurgicallyremovedwithinafewhoursbyadoctorfamiliarwiththis
type of injury or gangrene may result.
9. UndernocircumstancesshouldanymodicationsbemadetoBarkomachinerywithoutfactoryauthorization.Any
modicationsmayvoidthewarranty.Thismachinewasdesignedtodoaspecicjobandalterationscouldresult
in property damage, injury or death.
10. Replace any safety decals that are faded, torn, missing, illegible, or otherwise damaged. See your machine's
Decals section for decal kits applicable to your machine and for locations of all decals.

SAFETY SUMMARY CONTINUED...
CALIFORNIA
Proposition 65 Warning
Diesel engine exhaust and some of its constituents are known to
the State of California to cause cancer, birth defects, and other
reproductive harm.
Do not exceed 15 PSI nozzle pressure when drying
parts with compressed air. Do not direct compressed air
against human skin. Serious injury could result.
Older air conditioning equipment may contain R-12, a
substance which harms public health and environment
by destroying ozone in the upper atmosphere. To re-
move R-12 from the air conditioning system, use service
equipmentcertiedtomeettherequirementsofS.A.E.
J2209 or J1990.
On machines equipped with an accumulator, release all
pressure before working on the system. After service
work is done, repressurize the accumulator(s) to the
properspecication.
When you work on slopes there are several important points to consider:
Always use a seat belt when provided.
Speed of travel or working tools – higher speeds or sudden starts and stops can tend to make the machine
less stable
Terrain – soft ground, slopes, uneven surfaces (stumps, fallen trees and slash, rocks, valleys/rises, drop-offs
or ledges, overhangs), changing soil types, moisture, ice and snow affect the machine stability. Irregular
terrain must be traveled at slower speeds.
Direction of travel - Avoid operating the machine across the slope. When possible travel up or down slopes.
Place the heaviest end of the machine uphill and keep the load low to the ground. Turning uphill with an
articulated machine can increase the chance of tip-over.
Loads and shifting loads – Do not overload. Keep the load low and close to the machine. Contact with
overhead wires, trees, fallen trees or the ground can cause the load to shift unexpectedly and reduce stability.
Machineconguration–Willaffecttheweightdistribution,thestability,theoperatingperformance,andthe
machine control on slopes.
Visibility – irregular, snow-covered or slash-covered terrain can reduce visibility in the path of the tracks or
wheels and to the surrounding area, the load, other vehicles, obstacles, and people.
Condition of the machine – Machine control and performance when operating on slopes may require special
machinemaintenanceormorefrequentintervals.Fluidlevels,tracktensionortireinationpressurecanaffect
machine control on slopes.
Donotoperateamachineonaslopewithoutpropertraining.Learnthestabilitylimitsofthemachinebyrst
working on gentle slopes. Gain experience and improve skills over time by gradually increasing the angle
of slopes on which you are working. As operating conditions change make the appropriate decisions and
adjustments to maintain safe machine operation.

resuppressionequipment.
Anyportablereextinguisherorre
suppression system carried on the machine
that has been used, should be recharged
or replaced before the machine resumes
operating. Fire extinguisher manufacturers
recommended service intervals should be
followed.
Allow machine to cool down by idling the
engine for a while before shut-down. Many
engineandtransmissionresstartafter
shut-down.
Before adding fuel, shut down the engine and
allow it to cool. Never smoke while handling
fuel or working on either the fuel or the
hydraulic system.
Do not use the machine in areas with explo-
sive dust or gases that can be ignited by
arcs, sparks, hot components, or exhaust
fumes.
Dailyinspectthemachineforammable
debris, removing any twigs, leaves, straw,
rags,uidspillsorleaks,dirtorgrime.
Pay special attention to areas such as the
engine, engine cooling system, exhaust sys-
tem, battery, electrical connections, brake
systems, transmission/drivetrain, fuel system
and hydraulic system. Clean as often as
necessary to help prevent overheating and
combustion.
The electrical system (battery, electrical
connections, etc.) can be a source of arcs or
sparks if damaged or incorrectly maintained.
Daily inspect all electrical wiring and connec-
tions for damage. Keep the battery terminals
clean and tight. Replace or repair any dam-
aged part. Use proper battery connection and
disconnection procedures.
Daily inspect all fuel and hydraulic oil tubes,
hoses,andttingsfordamageandleakage.
Tighten or replace as necessary. Always
cleanuidspills.
Donotuseetherorstartinguidsondiesel
engines with glow plugs. These starting aids
can explode and injure bystanders.
Before doing welding of any kind, clean
machine and disconnect battery cables.
Coverrubberhoses,battery,andotheram-
mable parts. Never ground an arc welder or
electrical accessories through turntable or
boom bearings as arcing may occur causing
bearing damage.
Do not weld on any structural member unless
specicallyauthorizedbyBarko
Hydraulics. Any unauthorized welding or
welding procedures will void the warranty, and
may cause structural damage.
Read the Engine Manual that comes with ev-
ery machine for complete engine operating
and engine safety instructions.
INSTALLATION OF FIRE EXTINGUISHER BRACKET
Thecabshaveanoptionalreextinguishermounting

replacingoils,uids,orllingfueltank.
Donotweldonanystructuralmemberunlessspeci-
cally authorized by Barko Hydraulics. Any unauthorized
welding or welding procedures will void the warranty,
and may cause death, severe injury, property damage or
structural damage to the machine.
Do not support the machine on cinder blocks, hollow
tiles, or props that may crumble under a load. Do not
work under a machine that is supported solely by a jack.
Check the Hour Meter regularly to determine when the
machine needs periodic maintenance. Use the intervals
on the Service Schedule except when operating in ex-
treme conditions; then shorter intervals must be used.
Undernocircumstancesshouldanymodicationsbe
made to Barko machinery without factory authorization.
Anymodicationsmayvoidthewarranty.Thismachine
wasdesignedtodoaspecicjobandalterationscould

BEFORE INSPECTION OR MAINTENANCE:

Operation and Maintenance ManualLast Updated - 08/31/2016
495B ML TM (S)
18
Preventive maintenance is really just a simple matter of common sense. If you keep any piece of mechanical
equipment clean and properly lubricated, and promptly replace any worn or damaged parts, you are going to "prevent"
deterioration and promote long life and safe, productive service. The only other requisite to such a program is the
regular scheduling of such maintenance.
Obviously, when you are operating under severe job conditions, such as a dusty job site, in extreme heat or cold, a
long operating day, or extremely heavy loads, the recommended intervals in the schedule should be shortened.
The suggested schedule on the following page is designed to be just a reminder of what should be done. For detailed
instructions on each item, consult the Table of Contents for where each is located in this manual.
AFTER THE FIRST 100 HOURS OF OPERATION OF A NEW MACHINE
Anewmachineneedsaspecialmaintenanceprocedureaftertherst100hoursofoperation.
1. Do a complete inspection of the loader. Rectify any problems, replace any damaged parts.
2. Check torque (retorque if necessary):
- Turntable Bearing Mounting Bolts
- Mounting Bolts/Nuts on major machine components (gearboxes, motors, pumps, booms,
attachment, turntable bearing, lower assembly, tires, etc.)
3. Check torque of loader mounting bolts. Retorque if necessary.
  4. Changealllterelements.
Resume the normal maintenance intervals after this. See the Service Schedule for more information.
SPECIAL NEW-MACHINE INSTRUCTIONS
PREVENTIVE MAINTENANCE
Instructions are necessary before doing service on loader. See
warnings and instructions both at the beginning and throughout
this manual. After doing service or making repairs or adjustments
always check function of loader.
Safety glasses or goggles are always needed for eye protection
from electric arcs, from shorts or welding, battery acid, compressed
springs,uidsunderpressure,andyingdebrisorloosematerial
