to the neutral locked position and set the parking
brake.
3. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4. Allow the engine and hydraulic system to cool for
ten minutes.
Note: The oil level on the dipstick will be incorrect
when the oil is checked and the unit is hot.
5. Move the seat forward.
6. Clean the area around the dipsticks of hydraulic
system reservoirs (Figure 84).

WARNING
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.
