ATTACHMENTS (Using the X–Change System)
Removing Bucket or Attachment
The excavator is equipped with the X–Change system.
The X–Change is used for fast changing of buckets and
attachments.
NOTE: Removal and Installation of the bucket is
shown. The procedure is the same for other
attachments. Disconnect any hydraulic lines
that are operated by hydraulic power before
removing any attachments (breaker, auger,
etc.).
Stop the machine on a flat level surface. Put the bucket on
the ground.
Install the X–Change tool (Item 1) [A] in the latch. (The
tool is stored in the tailgate.)
Pull the tool (Item 1) [A] to unlock the latch. Remove the
tool.
Start the engine, lift the boom approximately one foot, and
extend the bucket cylinder until the X–Change pins (Item
1) [B] engage the hooks (Item 2) [B] on the bucket.
Retract the bucket cylinder and lower the boom and arm
until the bucket is on the ground, and the X–Change pins
(Item 1) [C] are disengaged from the hooks (Item 2) [C].
Move the arm toward the machine until the X–Change
pins are clear of the bucket.
