Video, Safety

4

Washers, 1/4 in. (for height of cut adjustment)

Parking Safely

1. Stop machine on a level surface, not on a slope.

2. Disengage mower blades.

3. Lock the park brake.

4. Stop the engine.

5. Remove the key.

6. Wait for engine and all moving parts to stop before you leave the operator’s station.

7. Close fuel shut-off valve, if your machine is equipped.

8. Remove the spark plug wire (for gasoline engines) before servicing the machine.

Checking Tire Pressure


MIF

c CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly:

• Do not attempt to mount a tire without the proper equipment and experience to perform the job.

• Do not inflate the tires above the recommended pressure.

• Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel.

• Do not stand in front or over the tire assembly when inflating. Use a clip-on chuck and extension hose long enough to allow you to stand to one side.

1. Check tires for damage.

2. Check tire pressure with an accurate gauge.

3. Add air, if necessary:

Tire Size

Pressure

Front 9x3.5-4

124 kPa (18 psi)

Rear 18x8.5-8

103 kPa (15 psi)


Check Fluid Levels

NOTE: Refer to the Service sections of the operator’s manual for information regarding check locations and proper fluid levels.

• Check engine oil level.

• Check hydraulic oil level.

Check Hydraulic System

c CAUTION: Avoid injury! Do not attempt this adjustment unless you are a qualified and properly trained technician. Improper adjustment can result in an unsafe machine.

Please make sure the unit is properly adjusted prior to operation. The hydraulic system may have air trapped in the system and reduce machine performance. If air has not been purged entirely, the unit may not track or neutral properly.
Please perform each of the checks listed below. Be sure to warm up unit for several minutes prior to performing each check listed below.
1. Check for air in Hydraulic System
2. Neutral and Tracking

Check for Air in Hydraulic System

Follow the steps below to verify air is not in the hydraulic system.

1. With the machine off disengage park brake.

2. Pull speed control lever back in neutral position.

3. Engage neutral locks.

4. Grasp console control handles and pull the unit manually toward reverse.

Condition 1: If the unit moves freely in reverse then air is in the system and needs to be purged. See “Bleed Hydrostatic System” procedure that follows.

Condition 2: If the unit does not move in reverse then air has been properly purged from the hydraulic system.

Neutral and Tracking Check

Next, verify unit is tracking correctly and does not creep. If adjustments are needed, please follow the “Check Speed Control Lever Position” in the Service Transmission section.

Bleed Hydrostatic System

c CAUTION: Avoid injury! Do not attempt this adjustment unless you are a qualified and properly trained technician. Improper adjustment can result in an unsafe machine.

1. Park machine safely.

2. Check level of hydraulic oil. Add oil as needed. (See “Hydrostatic Transmission and Hydraulic Oil” on page 314.)

IMPORTANT: Avoid damage! To prevent damage to hydrostatic pumps, never bleed or purge a pump under load. Always bleed with drive wheels off the ground.


3. Use a safe lifting device to raise the drive wheels off the ground. Support with jack stands.

c CAUTION: Avoid injury! Engine exhaust fumes contain carbon monoxide and can cause serious illness or death.

Move the machine to an outside area before running the engine.

Do not run an engine in an enclosed area without adequate ventilation.

• Connect a pipe extension to the engine exhaust pipe to direct the exhaust fumes out of the area.

• Allow fresh outside air into the work area to clear the exhaust fumes out.

4. Start engine and run at 3/4 speed.

5. Release neutral thumb latches and push speed control lever to full forward and let machine run for 5 seconds.

6. Squeeze triggers to run tires in reverse motion and hold for 5 seconds then release. Repeat 3 additional times.

7. Pull speed control lever back to neutral setting.

8. Engage neutral thumb latches and turn engine off.

9. Lower machine to the ground.

10. With the park brake disengaged, grasp console control handles and pull the unit manually toward reverse.

11. Does the unit roll backwards freely? If not, air is purged out of the system. If the unit continues to roll freely in reverse then air is still in the system and steps 6 & 7 need to be repeated.

NOTE: It may be necessary to repeat steps 6-7 until all air has been purged from system.

12. Once air is purged check oil level at hydraulic oil reservoir. Add oil as needed.

13. Verify unit is tracking properly. If the unit does not track properly then make adjustments by following the procedure below in “Neutral and Tracking Check”.

Check the Speed Control Lever Neutral Position

• Check the speed control lever neutral position. (See procedure in Service Transmission section.)

Check Mower Deck Level

• After machine is completely assembled check the front to rear and side to side mower deck level. (See procedures in Service Mower section.)

Check Machine Safety System

NOTE: Refer to the Operating section of the operator’s manual for information regarding safety systems.

Perform safety system checks to make sure the electronic safety interlock circuit is functioning properly.
