SAFETY AND ACCIDENT PREVENTION 2
MHL360 E 2.21
Wear protective gloves when searching for
leaks. A fine jet of pressurized fluid can
penetrate the skin.
Do not loosen any lines or screw couplings
until the loading equipment has been set
down, the diesel engine has been turned off
and pressure has been released from the
hydraulic system. Once the diesel engine
has been turned off, place the ignition key in
the contact position and move all joysticks
and similar devices (four-way control levers
and pedals) in both directions to release the
control pressure and dynamic pressures in
the hydraulic circuits. Then reduce the pres-
sure inside the container as described in
these operating instructions.
2.6.5 Electrical system
Check the electrical system regularly. Have
all faults such as loose connections, blown
fuses and filament lamps, or singed or worn
away cables repaired by specialist person-
nel immediately.
Use only original fuses with the recom-
mended current rating.
Work on electrical equipment must only be
performed by an electrical specialist or
trained persons under the supervision of an
electrician in accordance with electrical re-
quirements.
When working on live parts, enlist the assis-
tance of a second person to press the
emergency stop or battery isolator switch in
the event of an emergency. Close off the
work area with a red-and-white safety cor-
don and a warning sign. Use only electrical-
ly insulated tools.
Start by checking live parts to ensure they
are free of voltage. Then ground them and
short-circuit them. Isolate adjacent parts
that are under voltage.
Protect the control units before arc welding.

2.6.6 Hydroaccumulators
All work on hydroaccumulators must be
performed by trained specialist personnel
only.
Unsuitable mounting and handling of hy-
droaccumulators can result in serious acci-
dents.
Do not put damaged hydroaccumulators
into operation.
Before working on a hydroaccumulator, re-
duce the pressure in the hydraulic system
as described in these operating instructions.
Do not weld or solder onto the hydroaccu-
mulator and do not perform any mechanical
work. The hydroaccumulator can be dam-
aged by the effects of heat and can burst
due to mechanical processing. DANGER
OF EXPLOSION!
Only specialist personnel are permitted to fill
the hydroaccumulator with nitrogen. Using
oxygen or air will result in DANGER OF
EXPLOSION!
The body of the accumulator may become
hot during operation, resulting in a risk of
burns.
New hydroaccumulators must be filled with
the necessary pressure for the intended
purpose prior to putting the machine into
operation.
Operating data (minimum and maximum
pressure) must be constantly indicated on
the hydroaccumulators. The indicator must
remain permanently visible.
2.6.7 Hydraulic hoses and hose lines
It is forbidden to repair hydraulic hoses and
hydraulic hose lines!
All hoses, hose lines, and screw couplings
must be regularly inspected every 2 weeks
(or immediately if damage is suspected) for
leaks and externally visible damage! Re-
place any damaged parts immediately!
Spraying oil can cause injuries and/or fires.
