3.6 QUICK ATTACH ASSEMBLY
This vehicle is equipped with a quick attach system for
easy attachment changes.
3.6.1 Disconnecting from an Attachment
1. Park the vehicle on a hard, level surface.
2. Ground the attachment, place the travel select lever
in the (N) NEUTRAL DETENT position and engage
the parking brake switch.
3. Extend the boom approximately 10 ft (3 m) and tilt
the carriage backward. Shut the engine OFF.
4. Exit the vehicle using both hand holds.
Note: If removing a standard carriage with forks, spread
the forks apart on the carriage shaft. This will help give
the carriage better support to stand alone.
5. Raise the quick attach pin lock lever (5) and pull out the
lock pin (6) at the bottom of the quick attach.
6. Return to the operator’s compartment, fasten the seat
belt and lower the attachment to the ground in a level
position. Tilt the attachment forward; this will rotate
the quick attach link back away from the attachment.
7. Lower and then retract the boom until the
attachment pivot pins have disconnected from the
attachment.
3.6.2 Connecting to an Attachment
1. Perform this procedure on a hard level surface.
Position the vehicle directly behind the attachment to
be mounted.
2. Tilt the quick attach backward.
3. Extend the boom approximately 10 ft (3 m), and drive
the vehicle forward until the attachment pivot pins are
below and between the two hooks on the attachment.
4. Raise the boom until the attachment pivot pins have
seated fully in the hooks on the attachment.
5. Tilt the attachment up slightly. The quick attach link
should be tight up against the rear of the attachment,
and the holes in the link and the attachment should
be aligned.
6. Place the travel select lever in the (N) NEUTRAL
DETENT position, engage the parking brake switch,
unbuckle the seat belt and exit the vehicle using both
hand holds.
7. Lift the quick attach lever (5). Insert the quick attach
pin (6) completely through the attachment and the
quick attach link. Be sure that the quick attach lock
lever (5) has lowered and seated itself into the
groove in the quick attach pin (6).
8. Return to the cab, fasten the seat belt and resume
operation.
