Use jack stands to support the machine and/or
components when required.
CAUTION
Raising the machine for service or
maintenance relying solely on mechanical
or hydraulic jacks could be dangerous.
The mechanical or hydraulic jacks may not
be enough support or may malfunction
allowing the machine to fall, which could
cause injury.
Do not rely solely on mechanical or
hydraulic jacks for support. Use adequate
jack stands or equivalent support.
•
Carefully release pressure from components with
stored energy.
•
