capacity.
Never position yourself, walk or work underneath suspended loads.
Never use damaged lifting devices or devices which are not sufficient to carry the load.
Always wear gloves when handling wire cables.
Ask only experienced personnel to attach loads and guide and signal the crane operator. The
guide must be within the visibility range of the operator and /or must be in direct voice
contact with the operator.
When working overhead, use appropriate and safe ladders, scaffolding or other working
platforms designated for this purpose.
When working high above ground, make sure you are fitted with ropes and appropriate safety
devices which will prevent a possible fall.
Always keep handles, steps, railings, platforms and ladders free of dirt, snow and ice.
When working on the attachments, makes sure the attachment is supported properly. Never
use metal on metal support.
Never work underneath the machine if it is raised or propped up with the attachment. The
undercarriage must be supported with wooden blocks and supports.
If it is necessary to repair the track, block the chain with wedges and lock the upper-carriage.
Fluid escaping from a small hole can have enough force to penetrate the skin. So never check
for leaks with your bare hands, always wear gloves or make indirect check by other
instruments.
If it is necessary that the machine must be repaired on a grade, block the chains with wedges
and secure the upper-carriage to the undercarriage with the lock pin.
Never loosen or remove lines or fitting before the working device has been lowered to the
ground and the engine has been turned off. Then turn the ignition key to contact position,
move all servo controls (hand-control lever and foot pedals) in both direction to release
pressures. Then release the tank pressure as outlined in this Operation and Maintenance
Manual.
Always disconnect the battery cable before working on the electrical system or before any arc
welding on the machine. Always disconnect the negative cable first and reconnect it last.
HYDRAULIC LINES AND HOSES
All the hoses, lines and fittings must be checked regularly. It is better to check before start, to
check monthly, to check annually for leaks and any externally visible damage! Any damaged
sections must be replaced immediately! Escaping oil can cause injuries and fires!
Even if hoses and lines are stored and used properly, they undergo a natural aging process.
For that reason, their service life is limited.
Improper storage, mechanical damage and improper use are the most frequent causes of hose
failures.
The service life of a hose may not exceed six years, including a storage period of not more
than two years (always check the manufacturer’s date on the hoses).
Using hoses and lines close to the limit ranges of permitted use can shorten the service life
(for example at high temperatures, frequent working cycles, etc).
Hoses and lines must be replaced if any of the following points are found during an
