General Precautions for Removing and Installing the Hydraulic
System Components
Before Repairing or Replacing the Components
CAUTION
Before disconnecting or performing any work on the hydraulic
system, shut off the engine and press the motion control pedals
to release the pressure in the system and avoid injury from the
pressurized hydraulic fluid.
1. Before removing any parts from the hydraulic system, park the machine on a
level surface, shut off the engine, engage the parking brake if equipped or
remove the spark plug wire from the spark plug.
2. Clean the machine before you disconnect, remove, or disassemble the
hydraulic components.
Note:
Cleanliness is necessary whenever you work on the hydraulic
equipment. Ensure that you clean the hydraulic components, hoses,
connections, and fittings.
3. Label all the disconnected hydraulic lines and hoses for proper installation
after repairs are completed.
4. Record the orientation of the hydraulic fittings (especially elbow fittings) on
the hydraulic components before removal.
Note:
Mark the parts, if necessary before removal and ensure that they are
aligned properly when installing the hydraulic fittings, hoses, and tubes.
5. The hydraulic fluid may be hot. Be careful when you loosen and remove
the hydraulic system components.
6. Install clean caps or plugs on the hydraulic lines, hydraulic fittings, and
components that are left open or exposed to prevent hydraulic system
contamination. Cap the opening as soon as the line or port is exposed.
After Repairing or Replacing the Components
IMPORTANT
Drain and fill the hydraulic tank and change the oil filter if the
component failure is severe or the system is contaminated; refer to
Flushing the Hydraulic System (page 5–38)
.
1. Check the hydraulic fluid level in the hydraulic tank and add correct quantity
of fluid if necessary. Use hydraulic fluids that are specified in the GreensPro
Operator's Manual
.
2. When disposing of hazardous waste products (hydraulic fluid), take them
to an authorized disposal site. Waste products must not be allowed to
contaminate surface water, drains, or sewer systems.
3. On GreensPro 1260 machines, If a component failure occurs, filtering the
traction circuit is necessary; refer to
Filtering the Closed-Loop Traction Circuit
(GreensPro 1260) (page 5–39)
