ATTACHMENT REMOVAL AND INSTALLATION
WARNING
Check daily that the hoses and fittings in the quick coupler piping system are in good condition. Pay par-
ticular attention to the hoses and fittings at the arm end as these can be damaged easily. In case of dam-
age or leakage of oil stop work. Loss of oil could lead to the bucket or attachment falling and killing an
exposed person. The damage or leakage must be repaired before continuing work.
This machine has a system installed to give a warning if there is a failure to maintain pressure in the quick
coupler system. If the buzzer sounds in the cab make sure that the cause is clarified before continuing
work. In particular check for leaks in the system. If in doubt call your Komatsu dealer.
