Accessory Applications:
- The excavator has been primarily designed for moving earth with a bucket. For use as a grapple or for other object handling, contact Daewoo.
- Lifting work applications (unless restricted or prohibited by 330-111 Shop Manual SAFETY local regulations) are permitted in approved lift configuration, to rated capacity only, with no sideloading.
- DO NOT use the machine for activities for which it was not intended.
- DO NOT use the bucket for lifting work, unless lift slings are used in the approved configuration.
- Use of an accessory hydraulic hammer (breaker), work in rough terrain, demolition applications or other hazardous operation may require installation of additional protective structures to safeguard the operator.
- Refer to Section 3 for additional information on Falling Object Protective Structures (F.O.P.S.) and other reinforcement systems.
Lifting Capacity Rating Configuration:
- Lifting-capacity ratings that are printed at the end of this safety section are based on the machine being level, on a firm supporting surface, with hooks and slings attached in approved configuration.
- Loads must be balanced and supported evenly.
- Use taglines to keep the load steady if wind conditions and a large surface area are a problem.
- Work crew hand signals, individual tasks, and safe procedures, should all be universally understood before the lift is made.
IMPORTANT:
- Before using the excavator to make lifts check municipal and regional regulations or statutes that could apply.
- Governing ordinances may require that all heavy lifting be done with single purpose equipment specifically designed for making lifts, or other local restrictions may apply.
- Making heavy lifts with a general purpose excavator that can be used for digging, loading, grading or other work may be expressly forbidden by a regional injunction or other legal prohibition.
- Always follow all of the other instructions, guidelines and restrictions for Safe Lifting in the Operation and Maintenance and Shop Manuals.
Locations of Safety Labels:
- Always keep these labels clean.
- If they are lost or damaged, replace them with a new label.
- There are other labels in addition to the safety labels that follow, so handle them in the same way.
- Safety labels may be available in languages other than English.
- To find out what labels are available, contact your Daewoo distributor.
