Checking the Hydraulic Oil
Service Interval:
Every 40 hours - Check the hydraulic oil level.
1. Position the machine on a level surface.
2. Move the speed control lever to the neutral position
to stop the machine.
3. Disengage the PTO, engage the parking brake, stop
the engine, and wait for all moving parts to stop.
4. Allow the engine and the hydraulic system to cool
for 10 minutes.
NOTE: To get the correct reading, check the
hydraulic oil level when the machine is not
hot.
5. Tilt the seat forward and raise the hopper.
6. Clean the area around the dipstick of the hydraulic-
system reservoir.
7. Remove the dipstick from the hydraulic reservoir.
8. Wipe the dipstick off and thread the dipstick into the
reservoir.
9. Remove the dipstick and look at the end. If the oil
level is at the add mark, slowly pour only enough oil
into the hydraulic reservoir to raise the level to the
full line.
IMPORTANT: Do not overfill the hydraulic units with
oil as damage may occur. Do not run the machine with
the oil below the add mark.
10. Install the dipstick (Figure 20).

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 promptly.
• 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.
