5. Check the boom cylinder.
Check for leakage inside the boom cylinder (1)
a. With the bucket cylinder fully retracted and the
arm cylinder extended slightly from the fully re-
tracted position, lower the bucket tip to the
ground.
b. Disconnect hose (A) from the rod side only and
drain oil from the piping. Insert a plug (1) into the
disconnected hose.
c. Retract the arm cylinder to lift the bucket off the
ground. If oil leaks from the cylinder piping from
which the hose was disconnected and the boom
cylinder rod retracts, the cylinder is leaking inter-
nally. If no oil leaks from the cylinder piping and
the boom cylinder rod retracts, the control valve is
leaking internally.
Check for leakage inside the boom cylinder (2).
a. Set the machine in the posture shown in the fig-
ure.
