Lower everything to the ground before leaving the operator's
seat.
Do not use hollow, cracked or unsteady wobbling supports.

Action When Abnormality Is Found During
Inspection
If any abnormality is found during inspection, always carry out
repairs. In particular, if the machine is used when there are still
problems with the brake or work equipment systems, it may lead
to serious injury.
If necessary depending on the type of failure, please contact
your
DOOSAN distributor for repairs.
Precautions with High-pressure Lines,
Tubes and Hoses
When inspecting or replacing high-pressure piping or hoses,
check that the pressure has been released from the circuit.
Failure to release the pressure may lead to serious injury.
Always do the following;
• Wear protective glasses and leather gloves.
• Fluid leaks from hydraulic hoses or pressurized
components can be difficult to see but pressurized oil
has enough force to pierce the skin and cause
serious injury. Always use a piece of wood or
cardboard to check for suspected hydraulic leaks.
Never use your hands or expose your fingers.
• Do not bend high-pressure lines. Do not strike
high-pressure lines. Do not install lines, tubes or
hoses that are bent or damaged.
• Make sure that all clamps, guards and heat shields
are installed correctly to prevent vibration, rubbing
against other parts, and excessive heat during
operation.
– If any of the following conditions are found,
replace the part.
– Damage or leakage from hose end.
– Wear, damage, cutting of covering, or exposure
of strengthening wire layer.
– Cover portion is swollen in places.
