WARNING
!
To avoid serious injury or death:
To avoid serious injury, keep fingers and other body parts
away from articulating areas around grapple arms (#1),
grapple towers (#2 & #3), and hydraulic cylinders (#4).
1. Before assembling components, remove from inside
the bucket all unassembled components.
2. Lay grapple arm and tower assemblies on one side
or face down on the floor (not shown).
3. Remove port plugs “A” from hydraulic cylinders (#4).
Keep port plugs for reuse in steps 7 & 13.
4. Rotate left-hand tower (#2) on its back and then
rotate arm (#1) up until hydraulic cylinder (#4) is fully
extended as shown Figure 1-1.
5. Attach hoist or other suitable lifting device around
tower (#2) in the area designated “LIFT POINT”.
6. Rotate arm (#1) onto its side until it is resting on the
floor.
7.
Replace port plugs “A” in hydraulic cylinder (#4) to
help keep the cylinder from retracting while lifting the
arm and tower assembly.
8. Pick tower and arm assembly up with the lifting
device. If needed, lower unit to the floor and readjust
its straps around the lift point before transporting.
Refer to Figure 1-2:
9. Attach left-hand tower (#2) between brackets (#5)
with upper mounting pin (#8) and then the lower
mounting pin (#8). Secure mounting pins with
linchpins (#7).
Refer to Figure 1-1:
10. Rotate right-hand tower (#3) on its back and then
rotate arm (#1) up until hydraulic cylinder (#4) is fully
extended as shown Figure 1-1.
