WARNING
!
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 is 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 parts fracture causing death, severe 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
The following is a list of 10 important safety precautions and warnings you
should read through and understand before operating or servicing your machine.
Don't assume that because you know the control functions of other similar machinery, that
you can run and/or service the BARKO machine. 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 machine.
Know how to put your machine in a zero energy state for purposes of inspection,
maintenance, or repair.
Clear operating area of all obstacles and personnel before operating machine.
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!
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.
Never use a boom or attachment for a work platform or personnel carrier. Serious injury or
death may result.
When machine is not operating or when leaving cab, boom or lift arm 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.
Do not tamper with any hydraulic line when it is pressurized. Escaping fluid 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 fluids under high pressure. Use a piece of cardboard to search
for leaks.
If any fluid is injected into the skin, seek professional medical attention immediately!
Under no circumstances should any modifications be made to BARKO machinery without
factory authorization. Any modifications may void the warranty. This machine was designed to
do a specific job and alterations could result in property damage, injury or death.
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...)
ŸTerrain – 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.
SAFE OPERATION ON SLOPED TERRAIN
ŸDirection 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.
ŸVisibility – 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.
When you work on slopes there are several important points to consider:
ŸAlways use a seat belt when provided.
ŸSpeed of travel or working tools – higher speeds or sudden starts and stops can tend to make the machine
less stable
ŸLoads 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.
ŸCondition 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 inflation pressure can affect
machine control on slopes.
ŸDo not operate a machine on a slope without proper training. Learn the stability limits of the machine by first
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.
ŸMachine configuration – Will affect the weight distribution, the stability, the operating performance, and the
machine control on slopes.
WARNING
!
Any unauthorized welding, alterations, additions or
modifications made to Barko machinery will void
warranty. This machine was designed to do a specific job
and alterations could result in death, severe injury or
property damage. See WELDING SAFETY next page.
CAUTION
!
Check the Air Cleaner Assembly daily for cracks,
loose clamps, or any other damage. If debris is able to
bypass the Air Cleaner for any reason, it can damage the
engine.
WARNING
!
ŸTo remove R-12 from the air conditioning system, use
service equipment certified to meet the requirements of
S.A.E. J2209 or J1990.
Older air conditioning equipment may contain R-12, a
substance which harms public health and
environment by destroying ozone in the upper
atmosphere.
WARNING
!
On machines equipped with an accumulator, release
all pressure before working on the system. After
service work is done, pre-pressurize the accumulator(s) to
the proper specification.

FIRE PREVENTION
Always keep a fire extinguisher and first aid kit where
they can be easily reached in case of fire and keep
these items properly maintained.
ŸOperating personnel should be instructed on what to
do in case of fire and be required to demonstrate how
to use fire extinguisher and fire suppression equipment.
ŸAny portable fire extinguisher or fire 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
fires start after shut-down.
Do not use the machine in areas with explosive dust
or gases that can be ignited by arcs, sparks, hot
components, or exhaust fumes.
Read the Engine Manual that comes with every
machine for complete engine operating and engine
safety instructions.
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.
Inspect daily all fuel and hydraulic oil tubes, hoses,
and fittings for damage and leakage. Tighten or
replace as necessary. Always clean fluid spills.
Do not use ether or starting fluids on diesel engines
with glow plugs. These starting aids can explode and
injure bystanders.
Inspect the machine daily for flammable debris,
removing any twigs, leaves, straw, rags, fluid spills or
leaks, dirt or grime. Pay special attention to areas such
as the engine, engine cooling system, exhaust system,
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 connections for damage. Keep the battery terminals
clean and tight. Replace or repair any damaged part.
Use proper battery connection and disconnection
procedures.
ŸClean the machine often. High pressure washing of the machine is suggested every 1000 hours (or 6 months)
and always after a spill.
This machine may have several components which are at high temperatures under normal operating
conditions, such as the engine, exhaust system, brake system and transmission.
