1. Retract the boom and set the outriggers.
2. Boom down to minimum boom angle.
3. Loosen the two (2) cap screws on the left side of the upper and lower sheave shafts.
This will require a 3/ 4 inch hex wrench.
4. Reeve the hoist line over the top center sheave on the boom head, around the jib
sheave, and attach to the eye on the bottom of the jib tip.
5. Winch up to take the slack out of the hoist line and to take the weight of the jib off of
the jib offset pins.
NOTE: To prevent damaging the jib, do not winch up any more than is
necessary to loosen the jib offset pins.
6. Remove the jib offset pins from the 0° offset hole and place in the 15° hole or if you
are using 30° offset then place pins in tool box.
Never Remove Either 30° Pin
7. With the engine at idle, slowly winch down to pay out hoist cable. This will lower the
tip of the jib until the jib comes in contact with the jib offset pins.
NOTE: While lowering the tip of the jib, it may be necessary to raise the boom
to prevent the tip of the jib from touching the ground.
8. Remove the hoist line from the tip of the jib and reeve the hoist line as needed.
DECREASING OFFSET
Reverse above procedure to return jib to 0° offset position.
