9.15 Hydraulic system
9.15.1 Safety
Hydraulic components under pressure may perform
uncontrolled movements in case of improper handling.
Furthermore, medium may squirt out under high pressure
from pressurised components in case of a malfunction. Risk
of serious injuries or even death.
•
Only an authorised workshop is allowed to carry out work
on hydraulic components.
•
Before carrying out any work,
–
depressurise; discharge residual energies.
–
make sure to prevent accidental outflow of the
medium.
–
secure lifted movable machine parts against
accidental lowering.
–
safely park the machine and secure it against
accidental rolling and starting.
•
Have all hose pipes checked for their operational safety
by an expert at least once a year.
•
Regularly check all pipes, hoses and screwed
connections for leakage and visible damage. Eliminate
damage immediately.
•
Never try to plug hose pipe leaks with your hands or
fingers. Media squirting out under high pressure may
penetrate the skin and enter the body, potentially causing
serious injuries.
•
Never detect leakages with your bare hands. Immediately
contact an authorised workshop if a leak is suspected.
•
Immediately contact the medical services if injuries
caused by hydraulic oil occur. Risk of serious infection.
•
Risk of explosion due to improper work on hydraulic
accumulators.
– Welding, soldering, drilling or other work which might
affect the mechanical properties is not allowed.
