• Daewoo reserves the right to improve our products in a continuing process to provide the best possible product to the market place. These improvements can be implemented at any time with no obligation to change materials on previously sold products.
• It is recommended that consumers periodically contact their distributors for recent documentation on purchased equipment. This documentation may include attachments and optional equipment that is not available in your machine’s package.
• Please call your distributor for additional items that you may require. Illustrations used throughout this manual are used only as a representation of the actual piece of equipment, and may vary from the actual item.

General Safety Essentials Accessory Applications

The wheel loader has been designed primarily for moving earth with a bucket. For use as a grapple or for other object handling, contact Daewoo. Liftingwork applications are permitted in approved lift configuration, to rated capacity only, with no sideloading (unless prohibited by local regulation). 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. Working in rough terrain, use of an accessory hydraulic hammer (breaker), demolition applications, or other hazardous operation may require installation of additional protective structures to safeguard the operator.

Static Tipping Load

The machine can lift a maximum of 14,500 kg (31,967 lb) with the bucket in the Straight Ahead position, and a maximum of 12,000 kg (26,455 lb) with the bucket in the Fully Turned position. Hooks and slings must be attached to an eye that is in the center of the bucket. All lifts must be made with the machine standing on a firm and level surface. Loads must be balanced and supported evenly. Use taglines to keep the load steady if wind conditions and 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.

NOTE

Before using the wheel loader to make lifts, check the statutes at all levels of government that might have jurisdiction. Some governing bodies may require that all heavy lifting be done with a crane that is specifically designed for making lifts. When making lifts, always follow all 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, attach them again or replace them with a new label. Make sure replacement parts have current labels. 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
