GENERAL SAFETY ESSENTIALS
ACCESSORY APPLICATIONS
The excavator has been primarily designed for moving ear th with a bucket. For use as a gr apple or for
other obj ect ha ndling, contact Daew oo for p roper i nstallation and application. Lifting-work appl ications
(unless restricted or prohi bited by local regulations) are permitted in approved lift configuration, to rated
capacity only, with no side-loading. 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 ac cessory hydraulic hammer (breaker), work in rough terrain, demolition applications or ot her
hazardous operation may require installation of additional protective structures to safeguard the operator.
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 s upported evenly. Us e taglines to keep t he l oad steady if wi nd c onditions an d l arge
surface area are a problem. Work crew hand s ignals, individual tasks and s afe 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.

SUMMARY OF SAFETY PRECAUTIONS FOR LIFTING
IN DIGGING MODE
To lift safely while in Digging Mode, the following items must be evaluated by the operator and the work-site
crew.
• Condition of ground support
• Excavator configuration and attachments
• Weight, lifting height and lifting radius
• Safe rigging of the load
• Proper handling of the suspended load
Taglines on opposite sides of the load can be very helpful in keeping a suspended load secure, if they are
anchored safely to control points on the ground.
CAUTION!
Hot surfaces. Do not touch.
DANGER!
Unsafe use of the excavator while making rated lifts could cause serious, potentially fatal
injuries or extensive damage to the machine or nearby property. Do not let anyone operate the
machine unless they’ve been properly trained and understand the information in the Operation
and Maintenance Manual.
HAOA050L
15. 2022-7144E Operation and Maintenance Manual Safety 1-11
Always engage the "Digging Mode" control on the Instrument Panel before using the excavator for lifting
work.
UNAUTHORIZED MODIFICATIONS
Any modification made without authorization or written approval from Daewoo can create a safety hazard,
for which the machine owner must be held responsible.
For safety’s sake, replace all OEM parts with the correct authorized or genuine Daewoo part. For example,
not taking the time to replace fasteners, bolts or nuts with the correct replacement parts could lead to a
condition in which the safety of critical assemblies is dangerously compromised.
WORK-SITE PRECAUTIONS
ATTACHMENT PRECAUTIONS
Options kits a re a vailable through y our deal er. Co ntact Daew oo f or information on av ailable on e-way
(single-acting) and two-way (double-acting) piping/valving/auxiliary control kits. Because Daewoo cannot
anticipate, identify or test all of the attachments that owners may wish to install on their machines, please
contact Daewoo for authorization and approval of attachments, and their compatibility with options kits.
WARNING!
NEVER wrap a tagline around your hands or body.
NEVER rely on taglines or make rated lifts when wind gusts are in excess of 48.3 km/hr (30 mi/h).
Be prepared for any type of wind gust when working with loads that have a large surface area.
WARNING!
If you need more information or have any questions or concerns about safe operating
procedures or working the excavator correctly in a particular application or in the specific
conditions of your individual operating environment, please consult your local Daewoo
representative.
16. 1-12 Safety 2022-7144E Operation and Maintenance Manual
AVOID HIGH-VOLTAGE CABLES
Serious injury or death can result from contact
or pro ximity to h igh-voltage electric l ines. T he
bucket does not have to make physical contact
with power lines for current to be transmitted.
Use a s potter and hand s ignals t o stay aw ay
from pow er lines no t c learly v isible t o t he
operator.
Use these minimum distances as a guideline only. Depending upon the voltage in the line and atmospheric
conditions, strong current shocks can occur with the boom or bucket as far away as 4 - 6 m (13 - 20 ft) from
the power line. Very high voltage and rainy weather could further decrease that safety margin.
NOTE: Before s tarting any type of operation near po wer l ines (ei ther abov e ground or buried
cable-type), you should always contact the power utility directly and work out a safety plan
with them.
BEFORE STARTING TO DIG, CONTACT AUTHORITIES
Below ground hazards also include natural gas lines, water mains, tunnels and buried foundations. Know
what’s underneath the work-site before starting to dig.
BE AWARE OF HEIGHT OBSTACLES
Any type of object in the vicinity of the boom could represent a potential hazard, or cause the operator to
react suddenly and cause an accident. Use a spotter or signal person working near bridges, phone lines,
work-site scaffolds, or other obstructions.
USE CARE ON LOOSE SUPPORT
Working heavy loads over loose, soft ground or u neven, broken terrain can cause dangerous side load
conditions and possible tipover and injury. Travel without a load or balanced load may also be hazardous.
If temperatures are changing, be cautious of dark and wet patches when working or traveling over frozen
ground. Stay away from ditches, overhangs and al l other weak support surfaces. Halt wor k an d i nstall
support mats or blocking if work is required in an area of poor track support.
USE SOLID SUPPORT BLOCKING
Never rely on lift jacks or other inadequate supports when work is being done. Block tracks fore and aft to
prevent any movement.
