10. Fire Safety
CAUTION
Parts and attachments of the excavator reach high temperatures under normal operating conditions, particularly
the engine and the exhaust. Damaged electrical installations or electrical installations that have not been
maintained can be the cause of a spark discharge or arc. The following fire safety guidelines help you to maintain
your equipment efficient and to minimize the risk of fire.
•
Remove dirt in the area of hot parts such as the engine, exhaust, exhaust manifold and exhaust pipes, etc. The
machine should be cleaned more often with working with a heavy load.
•
Accumulations such as leave, straw, pine needles, branches, bark and other flammable materials must be
removed from the machine. This must be done especially in the vicinity of the exhaust system but also in the
superstructure and undercarriage and on the boom.
•
Check that all fuel lines and hydraulic lines are in good condition and for wear. If there are any defects, they
must be replaced immediately to prevent leaks.
•
Electrical cables and connections must be inspected regularly for damage. Damaged parts and lines must be
replaced or repaired BEFORE commissioning the machine. All electrical connections must be kept clean and
secure.
•
Exhaust pipes and the exhaust muffler must be inspected daily for leaks, damage and loose or missing screw
couplers. Leaking or damaged parts of the exhaust system must be replaced or repaired BEFORE operating the
machine.
•
Always keep a multifunctional fire extinguisher on near the machine. Become familiar with the operation of the
fire extinguisher. A fire in the electrical installation or the hydraulic system must be extinguished with a CO
2
fire extinguisher.
•
Two threads have been installed to the left of the driver’s seat to fasten a fire extinguisher.
NOTE
The fire extinguisher bottle is not part of the basic equipment of the machine.
