SUPER LONG FRONT BOOM AND ARM
TRANSPORT & STORAGE OF SUPER LONG FRONT MACHINE
INSTALLATION OF SUPPORTING LINK
q
For transportation or storage, always use the supporting
link to secure the arm and boom as shown. This will help
to prevent excessive force bearing on the boom and arm.
q
Other precautions for transport and storage can be found
in "TRANSPORTATION PROCEDURE" 3-169. of the stan-
dard machine manual.
Procedure for installing link
1. Lower the boom and extend the arm cylinder to set in the stow posture.
2. When the arm cylinder is almost at the end of the stroke,
lower the boom slowly to bring the bucket or bucket link
into light contact with the ground.
3. Remove the A end of the supporting link from the boom
(held by a pin), then install it to the arm with the pin. When
doing this, raise the boom slightly and retract the arm cylin-
der slightly from the end of its stroke (5 mm - 10 mm) to
align the holes correctly.
4. It is dangerous to carry out this operation with the arm
raised from the ground.
