600H SERIES OPERATOR MANUAL SET-UP
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.
10. Raise the boom to the horizontal position.
11. Extend boom approximately 1 foot (.3m).
12. Using tag line attached to jib sheave case, slowly swing
jib into stow position (parallel with 1
st
section boom),
Pins C1 are the jib pivot points during this operation.
:
13. Install jib swing pin B with spring clip through jib ear and
boom sheave case holes. This pin will keep the jib
assembly in line (parallel) with the I
st
section boom. Jib
swing pin B does not retain the jib in its stowed position
on the I
st
section boom.
14. Using boom telescope function, slowly retract boom.
The ramp/side stow bracket assembly on the side of the
1
st
section jib will engage the hook on the side of the 1
st
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.
15. 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.
16. 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.
17. Reinstall loadline over boom sheave case.

JIB REMOVAL
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.
When the jib is stowed on side of crane, always leave the
ram and handle sleeve of the jib jack pushed all the way
down to reduce exposure to rusting.
Jib Maintenance
1. Lubricate as outlined in Section 5.
2. Check for free rotation of jib sheave daily when using jib.
ANTI-TWO-BLOCK WEIGHT INSTALLATION
To prevent the hoist cable from slipping out of the ant-two-
block weight, rig the weight as shown in Figure 4-4.
CAUTION
Use caution when swinging jib to avoid unnecessary
impact with 1
st
section boom.
DANGER
Visually check all pin positions and make sure the 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.
CAUTION
The 41 ft (12.49 m) jib weights 960 lbs (435 kg) at 129 in.
(328 cm) when retracted from mounting pin holes.
FIGURE 4-4
The anti-two-block chain must be
