MAINTENANCE
USE WARNING TAG DURING SERVICE
Alert others that service or maintenance is
being performed and tag operator’s cab controls
– and other machine areas if required – with a
warning notice.
Warning tags for controls are available from
Daewoo distributors; see Figure 21.
DO NOT RUN ENGINE IF REPAIRS OR WORK ARE BEING PERFORMED ALONE
You should always have at least two people working together if engine must be run during service. One
person needs to remain in operator’s seat, ready to work controls or stop machine and shut "OFF" engine.
ALWAYS USE ADEQUATE EQUIPMENT SUPPORTS AND BLOCKING
Do not allow weight or equipment loads to remain suspended. Lower everything to ground before leaving
operator’s seat. Do not use hollow, cracked or unsteady, wobbling weight supports. Do not work under any
equipment supported solely by a lift jack.
DO NOT WORK ON HOT ENGINES OR HOT COOLING OR HYDRAULIC SYSTEMS
Wait for engine to cool off after normal operation. Park wheel loader on firm, level ground and lower all
equipment before shutting down and switching "OFF" controls. When engine lube oil, gearbox lubricant or
other fluids require change, wait for fluid temperatures to decrease to a moderate level before removing
drain plugs.
NOTE:
Oil will drain more quickly and completely if it is warm. Do not drain fluids at temperatures
exceeding 95°C (203°F), however do not allow full cool down.
COOL DOWN IS REQUIRED PRIOR TO
RADIATOR OR RESERVOIR CHECKS
Shut down engine and allow heat to dissipate
before performing service on engine radiator or
hydraulic fluid reservoir. Both assemblies have
air vent levers at or near filler cap for venting
built-up air pressure. Release levers before
trying to take off filler caps and LOOSEN CAPS
SLOWLY, before removal.
