Verification of Control Movements
1. Mount loader to tractor: Remove mount pins
from loader uprights. Align tractor with loader and
slowly drive tractor into loader. Shut off tractor.
2. Connect loader feedline hoses to tractor hydraulic
remote control hydraulic couplers. See Figure 12
for hose connections.
3. Mount loader to tractor by activating bucket
cylinders to raise or lower the loader uprights into
the loader mounts. Slowly drive tractor forward,
activating appropriate cylinders to engage loader
completely into mounts. Insert mounting pins to
secure loader.
4. Comply with all Safety Rules and start the tractor.
5. Check that all hydraulic control lever positions
operate the loader movements correctly as
shown in Figure 13.
6. If loader movements do not respond correctly,
shut off tractor, relieve pressure, and reconnect
properly. Loader control movements must be
correct before proceeding.
7. Once all loader functions are correct, start the
tractor and operate the loader to check for leaks.
Purge any remaining air from the hydraulic
system and check oil level.
8. When hose routings and correct loader
operations are verified, place a matching colored
band around male and female quick-disconnect
couplers. The colored bands will make re-
installation easier when the loader is removed
from the tractor.
9. Be sure that adequate slack is left in the hoses so
they can move as the loader moves through its
full range of motion.
10. Before operating the loader, make sure that the
Pre-Delivery, Delivery, and Pre-Operation Check
Lists from the Loader Operator’s Manual have
been completed.
