Hydraulic System
Maintenance

Hydraulic System Safety

•
Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
•
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.
•
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Checking the Hydraulic
Lines and Hoses
Service Interval: Before each use or daily
Check the hydraulic lines and hoses for leaks, kinked
lines, loose mounting supports, wear, loose fittings,
weather deterioration, and chemical deterioration.
Make all necessary repairs before operating.
Checking the Level of the
Hydraulic Fluid
Service Interval: Before each use or daily
The reservoir is filled at the factory with high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before you first start the engine and daily thereafter.
1. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Clean the area around the filler neck and cap of
the hydraulic tank (Figure 80).
1. Hydraulic-tank cap
3. Remove the cap from the filler neck.
4. Remove the dipstick from the filler neck and
wipe it with a clean rag.
5. Insert the dipstick into the filler neck; then
remove it and check the fluid level.
The fluid level should be between the 2 marks
on the dipstick.
6. If the level is low, add the appropriate fluid to
raise the level to the upper mark.
7. Install the dipstick and cap onto the filler neck.
