SERVICE PROCEDURE
5. Turn the starting switch to ON position (B).
6. Set the work equipment lock lever to FREE position (F), then
operate the blade control lever fully in LOWER direction and
check that the work equipment is completely in contact with the
ground.
7. If the work equipment goes down under its weight and contacts
the ground, the accumulator is normal.
If the work equipment does not go down or stops in midway,
the charged pressure of the gas in the accumulator for the
hydraulic circuit has probably dropped.
Ask your Komatsu distributor for inspection.
8. This completes the inspection. After completion of the inspection, set the work equipment lock lever to LOCK
position (L) and turn the starting switch to OFF position (A).
