HANDLE QUICK COUPLER
Quick coupler operation can be dangerous. There is a risk of death to exposed persons. Follow these
instructions strictly.
•
Use only quick couplers which comply with European standard EN474. In particular, it must be possible to
confirm from the operator's position that the locking of the attachment or bucket has been completed.
•
Use only the quick coupler which is with the pilot operated check valve in the rocking cylinder. This is to
ensure that there is no risk of the bucket or attachment coming loose in the case of loss of hydraulic pres-
sure. If in doubt consult the manufacturer of the coupler.
•
Read the instruction manual of the quick coupler carefully and follow the recommendations. If in doubt
about the installation or operation consult your Komatsu distributor.
•
Pressure regulation valve (2) allows the attachment pressure and the release pressure for the quick coupler
to be limited according to the coupler manufacturer's recommendation respectively. Check that the valve is
correctly set.
•
Ensure that the quick coupler is installed by a suitably qualified technician. If in doubt please contact your
Komatsu distributor.
