6. Repair Precaution & Examination
The primary complain occurring in the operation is mainly because of mechanical
parts and hydraulic parts problem.
Mechanical difficulties appears in each boom, CRACK occurred in other structures
and destroy, etc, hydraulic defects is hard to find, so check them well.
A. Check Points before Operation
A) Is hydraulic pressure oil in the oil tank sufficient?
Fill the Hydraulic pressure oil less than the minimum. (In this case less than the
middle of Oil pressure gauge on the tank)
Inspection of Hydraulic pressure oil check the outrigger on refold.
B) Isn't there oil leakage from connecting parts such as hydraulic pressure hose,
pipe, valve or cylinder?
Damage pipes and hoses need to replace, when poor connection make it
tighten.
C) Is there crack or damage of the structure?

pin etc?
G) Isn′t there damage of wires and cables?
B. Check Points during Operation
A) Is there leakage of hydraulic pressure oil?
B) Is there generation of suspicious noise during operation?
C) Isn't the temperature of hydraulic pressure oil very high?
D) During boom operation, does lifting of outrigger foothold appear in
phenomenon?
C. Check Points after Operation
A) Is the condition good as much as the next operation?
B) Is there crack or damage of the structure?
C) Isn't there oil leakage from connecting parts such as hydraulic pressure hose,
pipe?
