15. Route loadline over jib sheave and install keeper.
Install line block to end of loadline.
16. Remove anti-two-block weight/chain assembly
from boom tip switch and install on jib tip switch.
17. Disconnect twist lock quick coupler on anti-two-
block cord going to boom anti-two-block switch
and attach to quick coupler on jib anti-two-block
wire on rear of jib between the upper and lower
jib ears.
18. Install pin B and keeper into jib ears.
19. Unwrap ATB cord on side of jib to allow manu-
ally extending jibs to be deployed without dam-
age to the cord.
20. For manually extendable jibs, pull extension re-
tention pin E, and extend second section out by
pulling on sheave case. The second section jib,
as it extends, will hit a mechanical stop that al-
lows for extension pin E installation. Install pin
and keeper.
21. Make ATB cord connections as required.

1. Using lift function, lower boom so that jib tip is
close to the ground .
2. For manually extendable jibs, pull extension re-
tention pin and fully retract extendable 2nd sec-
tion jib into the 1st section. Retraction of 2nd
section may be facilitated by attaching loadline
wedge socket to attachment point F on the jib
sheave case. Slowly activate the winch up func-
tion until the 2nd section is fully retracted
3. Reinstall extension retention pin through the 1st
and 2nd section jib assembly and install spring
clip.
4. Remove loadline from jib sheave case. Place
loadline in area to avoid possible damage from
stow procedure.
5. Disconnect twist lock anti-two-block wire connec-
tor at rear of 1st section jib. Connect twist lock
connector to anti-two-block switch connector on
boom tip. Move anti-two-block weight assembly
to boom tip switch.
6. Attach tag line to sheave case end of jib.
7. Remove spring clips from pins C2 on both up-
per and lower jib ears.
8. Remove pins C2 from upper and lower jib ears.
Do not remove C1 pins at this time. C1 pins will
be used as a pivot point to swing jib into stow
position. A slight hammer strike may be neces-
sary to remove pins. Always use proper eye pro-
tection during this step. Utilization of the jib jack
at this time will aid in pin hole alignment to facili-
tate pin removal.
9. Using lift function, raise boom to a horizontal po-
sition.
10. Using extend function, extend boom approxi-
mately 1 foot.
11. Using tag line attached to jib sheave case, slowly
swing jib into stow position (parallel with 1st sec-
tion boom). Pins C1 are the jib pivot points dur-
ing this operation.

12. Install t-handle pin B through jib ear and boom
sheave case holes. This pin will keep the jib as-
sembly in line (parallel) with the 1st section boom.
Pin B %$ retain the jib in its stowed posi-
tion on the 1st section boom.
13. Using boom telescope function, slowly retract
boom. The ramp/bracket assembly on the side
of the 1st section jib will engage the hook on the
side of the 1st section boom, first lifting the jib
and then engaging the jib stow bracket and the
boom hook completely upon full retraction of the
boom.
14. Install stow pin A with spring clip into the ramp/
bracket assembly on the jib. Complete engage-
ment of stow brackets and proper installation of
pin A is critical for secure jib stow attachment.
15. Remove pins C1 from upper and lower jib ears.
A slight hammer strike may be necessary to re-
move pins. Always use proper eye protection
during this step.
16. Reinstall loadline over boom sheave case.

1. Lubricate sheave pin on jib with grease gun con-
taining chassis grease weekly.
2. Check for free rotation of jib sheave daily when
using jib.
