Connecting the Hydraulic Hoses
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected into
the skin must be surgically removed within a few
hours by a doctor familiar with this form of injury;
otherwise, gangrene may result.
•
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure
hydraulic fluid.
•
Use cardboard or paper to find hydraulic leaks;
never use your hands.
CAUTION
Hydraulic couplers, hydraulic lines/valves, and
hydraulic fluid may be hot. If you contact hot
components, you may be burned.
•
Wear gloves when operating the hydraulic
couplers.
•
Allow the traction unit to cool before touching
hydraulic components.
•
Do not touch hydraulic-fluid spills.
If the attachment requires hydraulics for operation, connect
the hydraulic hoses as follows:
1.
Shut off the engine.
2.
Move the auxiliary-hydraulics lever forward, backward,
and back to the neutral position to relieve pressure at
the hydraulic couplers.
3.
Move the auxiliary-hydraulics lever forward into the
D
ETENT
position.
4.
Remove the protective covers from the hydraulic
couplers on the traction unit.
5.
Ensure that all foreign matter is cleaned from the
hydraulic connectors.
6.
Push the attachment male connector into the female
connector on the traction unit.
Note:
When you connect the attachment male
connector first, you relieve any pressure buildup in the
attachment.
7.
Push the attachment female connector into the male
connector on the traction unit.
8.
Confirm that the connection is secure by pulling on
the hoses.
9.
Move the auxiliary-hydraulics lever to the N
EUTRAL
position.
Maximum Material Density at Capacity
The density of materials being moved by the bucket varies
and therefore so will the amount of a given material that can
be carried by the bucket before the maximum load rating is
reached. The first table lists the density of material that can
be carried, both heaped and struck (i.e., leveled off), in the
bucket. The second table lists common materials and their
densities.
To move materials with densities greater than the maximum
allowed for the bucket, reduce the volume of material placed
in the bucket.
