Safety rules

Hazards coming from the hydraulic system

If hydraulic oil gets into the eyes, rinse them immediately with clear water and subsequently seek medical aid.
Do not allow hydraulic oil to contact the skin or clothing. Skin parts which may have come in contact with hydraulic
oil must be washed with water and soap immediately, if possible. Do this thoroughly and repeatedly, otherwise
there is a risk of damage to the skin.
Immediately take off any clothes dirtied or soaked with hydraulic oil.
Persons who have inhaled hydraulic oil vapours (mist) should be taken to a doctor immediately.
If leaks have occurred in the hydraulic system, the excavator may not be taken into operation or, if in operation,
operation must cease at once.
Do not use the naked hand to search for leaks; always use a piece of wood or cardboard. Protective clothing (eye
protection and gloves) must be worn when seeking leaks.
Leaking hydraulic oil must be bound immediately with an oil binding agent. The contaminated oil binding agent
must be stored in suitable containers and in accordance with the valid regulations.

Fire protection

The excavator components and attachments (in particular the engine and the exhaust system) reach
high temperatures even at normal working conditions. An electric installation which is damaged or
STOP
not properly serviced may lead to flashovers and/or electric arcs. The following Fire Protection Guide-
lines may help you ensure the maintenance and efficiency of your equipment and minimize fire haz-
ards.
Remove any accumulated dirt adjacent to hot components, e.g. engine, muffler, exhaust manifold/tubes, etc.
!
If the machine is being used to full capacity, the cleaning procedure should be performed more frequently.
Accumulated residues from plants and trees, or any other flammable materials, should be removed from the
!
machine. This must be observed in particular in the proximity of the engine and the exhaust system, but also
at the swivel frame, the track frame, and the boom.
Check the condition and wear of all fuel lines and hydraulic hoses. Any defective parts should be replaced
!
immediately in order to avoid leakage.
Electric lines and connections must be checked regularly for signs of damage. Damaged components and
!
lines must be replaced or repaired before starting up the machine. All electric connections must be kept clean
and solid.
Exhaust pipes and mufflers must be checked daily for leaks, damage and any loose or missing joints. Leaking
!
or damaged exhaust system components must be replaced or repaired before starting up the machine.
Always keep a multipurpose fire extinguisher at or close to the machine. Make yourself familiar with the op-
!
eration of the fire extinguisher. In the event of fire in the electrical or hydraulic system, use a CO
guisher to combat the fire.
For attaching a fire extinguisher (1) two threads (2) have been inserted in the cab construction on the left side
!
behind the driver's seat.
