1. Move the machine onto a level surface and set the
parking brake.

3. Remove the cap from the filler neck and look inside to
check if there is fluid in the reservoir (Fig. 40).
4. If there is no fluid, add fluid to the reservoir until it
reaches the Cold level of the baffle.
5. Run the machine at low idle for 15 minutes to allow any
air to purge out of the system and warm the fluid. Refer
to Starting and Stopping the Engine on page 20.
6. Check the fluid level while the fluid is warm. The fluid
should be between the Cold and Hot levels.
7. If required, add fluid to the hydraulic tank.
Note: The fluid level should be to the top of the Hot
level of the baffle when the fluid is hot (Fig. 40).
8. Install cap on filler neck.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
•
If hydraulic fluid is injected into the skin, it
must be surgically removed within a few hours
by a doctor familiar with this type of injury;
otherwise, gangrene may result.
•
Keep your body and hands away from pin hole
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.
•
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.
Warning
Replacing the Hydraulic Filter
Change the hydraulic filter:
•
After the first 8 operating hours
•
After every 200 operating hours
Use a summer filter above 32
°
F (0
°
C)
Use a winter filter below 32
°
F (0
°
C)
1. Disengage the 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
position.
Important
Do not substitute an automotive oil filter for
a hydraulic filter; this can severely damage the hydraulic
system.
3. Place a drain pan under the filter, remove the old filter,
and wipe the filter adapter gasket surface clean
(Fig. 41).
