Dipstick locations
Hydraulic oil escaping under pressure can
penetrate skin and cause injury.
•
If hydraulic oil is injected into the skin it
must be surgically removed within a few
hours by a doctor familiar with this type of
injury. Gangrene may result if this is not
done.
•
Keep body and hands away from pin hole
leaks or nozzles that eject high pressure
hydraulic oil.
•
Use cardboard or paper to find hydraulic
leaks.
•
Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
•
Make sure all hydraulic oil hoses and lines
are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to hydraulic system.
Replacing the Hydraulic Filters and
Hydraulic Oil
Service Interval:

Every 500 hours
To replace the hydraulic oil, the filters need to be
removed. Replace both at the same time. Refer to the
oil specifications under Servicing the Hydraulic System
for the correct oil.
1. Disengage the blade control switch (PTO), move the
motion control levers to the neutral locked position
and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating

3. Raise the machine and support it with jack stands
(Figure 83).

4. Remove both the mower belt and the pump drive
