Operating the Machine
5. Rotate the Quick-Disconnect Hitch to seat the rear of
the latch over the rear attachment pins (D).
CAUTION: Do not raise the attachment without
acceptable wedge engagement. The attachment
can fall causing possible injury to people in the
vicinity of attachment.
6. Move the latch switch to the latch position and move
the control in order to carefully curl the
Quick-Disconnect Hitch and the attachment to full
extension of the bucket cylinder. This will place oil over
relief and divert oil to the hydraulic latch cylinder in
order to engage the wedge into the attachment.
NOTE: Keep the attachment close to the ground during
all latch and unlatch operations.
CAUTION: Wedge must be engaged into
attachment.

mechanically secure the attachment in
the event of hydraulic system failure.
The machine should not be operated
without the safety lock pin in the locked
position (E).
7. The safety lock pin lever is at the rear of the
Quick-Disconnect Hitch. Carefully rotate the spring
loaded safety lock pin lever toward the excavator to
engage the lock pin.
