SAFE OPERATION -1 SAFE OPERATION Careful operation is your best insurance against an accident. Read and understand this manual carefully, before operating the excavator. Every user, however experienced, should carefully read and understand this manual and those of the attachments and accessories before operating the excavator. The owner is obliged to inform all operators of these instructions in detail. Keep this manual in the storage location.
-2 SAFE OPERATION 9. Check the surroundings carefully before using the excavator or when attachments are being attached. A Pay attention to the overhead clearance with electric wires. A Check for pipes and buried cables before digging. Use your local utility service to check for such items (if available). A Check for hidden holes, obstacles, soft underground, and overhangs. A Do not allow any persons within the working range of the excavator during operation. 10.
SAFE OPERATION 2. OPERATING THE EXCAVATOR Operator safety is a priority. Safe operation, specifically with respect to overturning hazards, entails understanding the equipment and environmental conditions at the time of use. Some prohibited uses which can affect overturning hazards include traveling and turning with implements and loads carried too high etc. This manual sets forth some of the obvious risks, but the list is not, and cannot be, exhaustive.
-4 SAFE OPERATION 7. When the working light and CAB light alone do not provide sufficient visibility, prepare additional stationary artificial lighting and observe safety rules for night work. 8. When towing the excavator or pulling a load, the load must be less than the strength of the towing line attached to excavator. Max. drawbar pull at coupling hook 72 kN (7340 kgf) Max. vertical load at coupling hook 40 kN (4080 kgf) 5. Never allow children to operate the machine even under adult supervision.
SAFE OPERATION 4. SAFE LOADING AND TRANSPORT OF THE EXCAVATOR 1. Observe all regulations concerning the transport of excavators on public roads. 2. Use adequately long and robust ramps when loading on the machine. (for details see "TRANSPORTING THE EXCAVATOR ON A VEHICLE") 3. Do not change the running direction and to avoid tipping over, do not try to swing the attachment crosswise to the loading ramps. 4. Lower the attachment on the loading bed and release the pressure from the hydraulic system.
-6 SAFE OPERATION 9. Oil under high pressure can penetrate the skin and may be harmful to your health if not treated immediately. 10. Leaking hydraulic fluid has enough pressure to penetrate the skin and cause serious injuries. Leakages from pin holes can be totally invisible. Do not use hands for checking for leaks. Always use a piece of wood or cardboard. It is strongly recommended that you use a face mask or eye protection.
SAFE OPERATION A Inspect all fuel lines and hydraulic hoses for wear or for deterioration. Replace them immediately if they begin to leak. A Examine electrical wiring and connectors frequently for damage. Repair any wires that are loose or frayed before operating the machine. Clean all electrical connections and tighten all electrical connections as necessary. A Inspect the exhaust system daily for any signs of leakage.
