ment.

REMARK
The switch has a safety lock mechanism to prevent acci-
dental operation. Slide the lock towards you then rock the
switch. The lamp on the switch will come on and a warning
buzzer will sound.
3. With switch (1) in position "B" press and hold button (2) on
the left hand lever, to activate quick coupler.

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 ("Lamp Switch (3-78)"). The quick cou-
pler will move to the 'released' position.
5. 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 manufac-
turer's instructions.
6. Release button (2). The quick coupler will lock onto the
bucket or attachment, if necessary operate one of the
machine control levers to raise the system pressure.
Return switch (1) to position "A" (OFF). The lamp will go off
and the buzzer stop.
7. If the bucket or attachment needs a connection to the
hydraulic system of the machine follow all instructions in
"REMOVAL AND INSTALLATION OF ATTACHMENT (6-
