2.3.4 Hydraulic system
CAUTION! Only personnel certified in hydraulics are permitted to perform opera-
tions on the hydraulic system.
CAUTION! Never adjust pressure relief valves beyond the recommended values.
Make sure all defective hoses, valves or fittings are checked, repaired and
replaced before starting the equipment.
2.3.5 Lifting and moving loads
CAUTION! Only personnel with adequate lifting training are permitted to perform
lifting operation.
Make sure that the capacity of the lifting equipment is adequate and that the
equipment itself is in good working order.
If a lifting tackle has to be made up by joining separate components, make
sure that the joints are secure and have the same lifting capacity as the rest of
the tackle.
Always engage the safety clips on lifting hooks to prevent the tackle from
slipping off.
Use ropes or poles to steady and maneuver loads. Do not use hands or feet.
Make sure that the route and the destination are free from obstacles before
moving a suspended load. It must be possible to lower the load to the floor
quickly and safely in an emergency.
When depositing loads, keep the lifting equipment in place until the stability
of the load has been checked.
WARNING!
Oil pressure
Pressurized oil is dangerous if released incorrectly. Relieve all
pressure before carrying out maintenance or repair work on the
hydraulic system.
WARNING!
Oil temperature
Hydraulic oil can get very hot in operation. Allow the oil to cool before
working on the hydraulic system.
DANGER!
Hanging load
Never work or stand underneath a crane that is lifting material. Keep a
safe distance from a hanging load.
NOTE! Always use lifting tackle certified in accordance with local conditions.
