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.
• Ensure that all hydraulic-fluid hoses
and lines are in good condition and all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
• 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 machine 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 and remove the key.
2. Move the auxiliary-hydraulics lever forward,
backward, and back to the N
relieve pressure at the hydraulic couplers.
3. Remove the protective covers from the hydraulic
connectors on the machine.
4. Ensure that all foreign matter is cleaned from
the hydraulic connectors.
5. Push the attachment male connector into the
female connector on the machine.
Note:
When you connect the attachment male
connector first, you relieve any pressure built
up in the attachment.
6. Push the attachment female connector onto the
male connector on the machine.

7. Confirm that the connection is secure by pulling
on the hoses.
Removing an Attachment
1. Park the machine on a level surface.
2. Lower the attachment to the ground.
3. Shut off the engine and remove the key.
4. Disengage the quick-attach pins by turning them
to the outside.
5. If the attachment uses hydraulics, move the
auxiliary-hydraulics lever forward, backward,
and back to the N
pressure at the hydraulic couplers.
6. If the attachment uses hydraulics, slide the
collars back on the hydraulic couplers and
disconnect them.
Important:
Connect the attachment hoses
together to prevent hydraulic system
contamination during storage.
7. Install the protective covers onto the hydraulic
couplers on the machine.
8. Start the engine, tilt the mount plate forward, and
back the machine away from the attachment.
