The following maintenance section gives suggested guidelines for operational maintenance on your machine. It is not
intended for use as a service manual.
In severe conditions (extreme dust, heat, cold, humidity, etc.) you will need to service your machine more often. Your
experience will dictate a more severe servicing program.
Safety while servicing your machine is your responsibility. Only qualified and authorized personnel should be
permitted to maintain, repair, adjust and inspect machine.
Read and understand warnings and safety precautions in Safety Summary and elsewhere in this manual before doing
any service on machine. The following precautions should be used as a reminder to safe servicing.
SAFETY WHILE SERVICING
REMEMBER: SAFETY FIRST!
Always shut down the machine and lower the boom and
attachment to the ground before working on the ma-
chine. If necessary to work on a lifted boom or attach-
ment, securely support the boom and attachment so that
they cannot move or fall in any way.
Don't leave loose tools and rags on the
machine. Ensure that all walking and climbing surfaces
are clean.
Handle fuel carefully. Do not smoke while filling fuel tank
or working near fuel.
Refer to Fluid Specifications whenever
replacing oils, fluids, or filling fuel tank.
Do not weld on any structural member unless specifi -
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 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 death, severe injury or property damage.
Relieve all hydraulic pressure before breaking any hy-
draulic connection, opening the reservoir access cover,
or performing any maintenance on the machine.
- Lower boom to ground.
- Shut down machine to a zero energy state.
- Remove key from ignition.
- Disengage servo lever.
- Allow machine to cool.
- Relieve all hydraulic pressure.
- Disconnect battery using battery disconnect switch.
- Remove, block or guard against body contact with all
other sources of hazardous pressure, temperature,
electricity, or machine motion.
- Ensure machine, boom or attachment are not
supported on props that may collapse. Ensure boom
and attachment are grounded.
