Stowing Procedure
NOTE: When lowering the boom below horizontal, two
persons may be required. With the telescope
control in neutral, the boom may creep out when
below horizontal.
1. Using lift function, lower boom so that jib tip is close to
the ground.
2. For manually extendable jibs, pull extension retention
pin and fully retract extendable 2nd section 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 hoist up
function until the 2nd section is fully retracted.
3. Reinstall extension retention pin E 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 connector at
rear of 1st section jib. Connect twist lock connector to
anti-two-block switch connector on boom tip. Move
weight/chain assembly to boom tip.
6. Attach tag line to sheave case end of jib.
7. Remove spring clips from pins C2 on both upper 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 necessary to remove pins.
Always use proper eye protection during this step.
9. Using lift function, raise boom to a horizontal position.
10. Using extend function, extend boom approximately 1 ft
(0,3 m).
11. Using tag line attached to jib sheave case, slowly swing
jib into stow position (parallel with 1st section boom).
Pins C1 are the jib pivot points during this operation.
Use caution when swinging jib to avoid
unnecessary impact with 1st section boom.
12. Install jib swing pin B with spring clip through jib ear and
boom sheave case holes. This pin will keep the jib
assembly in proper alignment with the 1st section boom.
Jib swing pin B does not retain the jib in its stowed
position on the 1st section boom.
13. Using boom telescope function, slowly retract boom.
The ramp/side stow 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
side stow bracket and the boom hook completely upon
full retraction of the boom.
14. Install stow pin A with spring clip into the ramp/ side stow
bracket assembly on the jib. Complete engagement 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 remove pins.
Always use proper eye protection during this step.
16. Reinstall loadline over boom sheave case.
Visually check all pin positions to assure Jib is fully
retracted into side stow brackets, jib stow attachment is
secure, and all pins and spring clips are in their proper
locations. Failure to proper secure the jib during
stowing and erecting may allow the jib to fall. Serious/
Personal injury or death could result.
Always have at least one, if not both of the following
in place at all times:
• Side stow bracket completely engaged into stow
hook with stow pin A properly in place.
• Both pins C1 in upper and lower jib holes
properly in place through mating holes on boom tip.
JIB MAINTENANCE
1. Lubricate sheave pin on jib with grease gun containing
chassis grease weekly.
2. Check for free rotation of jib sheave daily when using jib.
JIB REMOVAL
The 30 ft jib weight is 850 lb (385 kg) at 157 in (398 cm)
from mounting pin holes. The 54 ft jib weight is 1450 lb (657
kg) at 167 in (424 cm) when retracted from mounting pin
holes. Should jib removal from the boom become necessary,
proceed as follows:
1. Unstow and swing jib into position on the boom
tip according to Steps 1 -10 in the preceding jib
deployment section.
2. Support and raise the jib at its balance point and remove
the two swing around pins. Jib is now free of boom.
3. To install, proceed in reverse order of removal.
