QUICK COUPLER SYSTEM
3.
Keep the button (2) on the left joystick pressed to activate
quick coupling.
4.
Depending on the design of the quick coupler it may be
necessary to operate one of the hydraulic functions of the
machine (bucket, boom, arm or swing) to raise the pres-
sure in the hydraulic system.
The quick coupler will now release the attachment/bucket.
TO PICK UP A NEW BUCKET OR ATTACHMENT
• European safety standards require that it is possible to check the locked position of the quick cou-
pler from the operator's position. Failure to check could cause the death of exposed persons.
Check carefully that all the locking of the quick coupler is complete and secure. Follow the manu-
facturer's instructions carefully, including the installation of any safety device, if required.
• Check daily that the hoses and fittings in the quick coupler piping system are in good condition.
Pay particular attention to the hoses and fittings at the arm end as these can be damaged easily. In
case of damage or leakage of oil stop work. Loss of oil could lead to the bucket or attachment fall-
ing 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. Whenever the alarm indicator for the hydraulic attachment and level is
displayed on the monitor "L03", stop the machine immediately and contact your Komatsu dealer to
get an inspection carried out.
