OPERATION 6
To release a bucket or attachment
1. If the bucket or attachment has any hydraulic connections to the machine these must be disconnected before
proceeding.
WARNING
Pressure in the system can cause injury. Follow all instructions in ATTACHMENT REMOVAL AND INSTAL-
LATION.
2. Position the attachment on the ground safely where it is to
be left. Take care that it will not roll or slide after release.
3. Operate the switch (1).
NOTE: The switch has a safety lock mechanism to prevent
accidental operation. Slide the lock towards you then
rock the switch. The lamp on the switch will come on
and a warning buzzer will sound.
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 pressure in the hydraulic system. If using the swing
function activate the Swing Lock first (See “Swing Lock Switch” on page 19.).
5. The quick coupler will now release the attachment/bucket.

3. 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 pressure in the hydraulic system. If using the swing
function activate the Swing Lock first (See “Swing Lock Switch” on page 19.). The quick coupler will move to
the 'released' position.
4. Position the quick coupler in the mating portion of the bucket or attachment, moving the bucket cylinder, arm
and boom as necessary. Follow the quick coupler manufacturer's instructions.
