Hydraulic System Safety
• Seek immediate medical attention if uid is injected
into skin. Injected uid must be surgically removed
within a few hours by a doctor .
• Ensure that all hydraulic-uid hoses and lines are
in good condition and all hydraulic connections
and ttings 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
uid.
• Use cardboard or paper to nd hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.

Checking the Hydraulic
Fluid
Service Interval : Every 50 hours —Check the
hydraulic-uid level.
1. Park the machine on a level surface, disengage
the blade-control switch (PT O), and engage the
parking brake.
2. Shut of f the engine, remove the key , and wait
for all moving parts to stop before leaving the
operating position.
3. Allow the engine and the hydraulic system to
cool for 10 minutes.
Note: The oil level on the dipstick is incorrect
when the oil is checked and the machine is hot.
4. Move the seat forward.
5. Clean the area around the dipsticks of
hydraulic-system reservoirs ( Figure 101 ).
6. Remove 1 dipstick from the hydraulic reservoir
( Figure 101 ).
7. Wipe the dipstick of f and thread the dipstick into
the reservoir .
8. Remove the dipstick and look at the end ( Figure
101 ).
Important: Do not overll the hydraulic
units with uid, as damage may occur . Do
not run the machine with uid below the add
mark.
9. If the uid level is at the add mark, slowly pour
only enough uid into the hydraulic reservoir to
raise the level to the full or H line.
10. Install the dipstick.
1 1. Repeat the procedure for the opposite dipstick.
