THIRD MEMBER ATTACHMENT MOUNTING PROCEDURE
1. Locate flat, hard ground (e.g., concrete floor) for installation. Place the attachment on the ground and use
blocking if necessary.
2.
Remove the bucket or other attachment from the end of the excavator stick following the manufacturer’s
recommended procedure.
3. Take care to properly plug any hydraulic hoses when disconnected to prevent contamination from entering
the hydraulic system.
4. With the jaws of the attachment facing the excavator, bring the excavator into position, carefully lining up
the stick tip with the proper connection on the attachment mounting bracket.
5. Pin the excavator stick tip to the mounting bracket stick connection using the pin provided.
6. Carefully extend the bucket cylinder to move the bucket linkage forward far enough to position the link
into the mounting bracket linkage connection (see Figure 3-2). It may be necessary to use a lifting device
(overhead hoist, forklift, etc.) to correctly position the link.
7.
Pin the link to the linkage connection using the pin provided.
On third member mounting brackets, the stick and
link-age connections can be difficult to tell apart,
because they often have the same dimensions. In
nearly all cases, the linkage connection is the one
closest to the rotation components.
NOTICE
Never move or operate the attachment without
all collars and hardware installed on the connect-
ing pins.
