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.
AVOID HIGH-VOLTAGE CABLES
Serious injury or deat h 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 da ngerous side load
conditions and possible tipover and injury. Travel without a load or balanced load may also be hazardous.
