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 a firm, level surface 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.
HYDRAULIC CYLINDER SEALS REQUIRE PERIODIC REPLACEMENT
Check cylinder drift rate at regular intervals. Overhaul seal kits are available through
DOOSAN
.
HIGH PRESSURE HYDRAULIC LINES CAN STORE A GREAT DEAL OF ENERGY
Exposed hydraulic hoses on arm could react with explosive force if struck by a falling rock, overhead
obstacle or other job site hazard. Extra safety guards may be required. NEVER allow hoses to be hit, bent
or interfered with during operation.
