Performing Daily Maintenance Operation Before Operation Before starting the machine each day, perform the Each Use/Daily procedures listed in Daily Maintenance Checklist (page 41). Before Operation Safety Checking the Air Pressure in the Tires General Safety • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.
Checking the Safety-Interlock System Engine Cranking Interlock Table (cont'd.) Result Conditions The purpose of the safety-interlock system is to prevent the engine from cranking or starting unless the traction pedal is in neutral, the PTO switch is in the OFF position, the parking brake is engaged, or the operator is in the seat.
Adding Fuel Checking the PTO Safety-Interlock System Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness. Service Interval: Before each use or daily Before doing the following checks, perform the following: 1. Sit in the operator’s seat. Fuel tank capacity: 41 L (10.8 US gallons) 2. Engage the parking brake. 3.
Adjusting the Rollover Protection System (ROPS) Filling the Fuel Tank Note: If possible, fill the fuel tank after each use; this minimizes possible buildup of condensation inside the fuel tank. WARNING To avoid injury or death from rollover, keep the roll bar in the raised locked position and use the seat belt. Ensure that the seat is secured with the seat latch. WARNING There is no rollover protection when the roll bar is in the down position.
7. Adjusting the Tilt-Steering Column Tilt the seat rear to the locked position (Figure 15). Adjust the tilt-steering column to your desired position as shown in Figure 17. g218001 Figure 15 g214731 Figure 17 Raising the Roll Bar 1. 2. 3. 4. 5. 6. 7. Park the machine on a level surface.

Leveling the Mower Deck Preparing to Level the Deck 1. Park the machine on a flat level surface. 2. Lower the mower deck and set the deck-lift lever to the float position. 3. Check bent or damaged mower blades or wing-blade disks, refer to Inspecting the Blades (page 72). Note: Replace bent or damaged blades and disks before leveling the deck. g232023 Leveling the Mower Deck Left to Right 1. Adjust the height of cut to the 75 mm (3 inches) position (Figure 121). g231917 Figure 122 1.

Adjusting the Height-of-Cut Pointer 1. 2. Checking the Mower Deck Belt Tension With the mower blades aligned front to back and the front of the blades adjusted to 75 mm (3 inches) from the ground, check the position of the height-of-cut indicator. Sit in the operator’s seat and look at the pointer of the height-of-cut indicator (Figure 130). Service Interval: After the first 50 hours Every 50 hours 1. Park the machine on a level surface. 2.
Switching the Skids When the skids wear out, you can switch them to the other side of the mower deck to gain additional use. g231993 Figure 133 1. Belt-tensioning pulley 3. Washer 2.

Troubleshooting Problem The key switch is in the ON position, but the dash panel indicator lights do not turn on. The dash panel indicator lights turn on with the key switch in the ON position, but the starter motor does not turn. The engine starts only intermittently or the engine runs irregularly. The starter motor turns, but the engine does not start. The engine shuts off while the PTO is still engaged. The cut is uneven and collection system is insufficient. Possible Cause 1.
Problem The engine-oil warning light illuminates. The mower deck does not run when the PTO switch is engaged. Possible Cause Corrective Action 1. The engine-oil pressure is insufficient. 1. Check the engine-oil level and fill it, if necessary. 2. The engine-oil pressure is insufficient. 2. Change the engine oil and engine-oil filter. 1. The operator is not in the seat. 1. Sit in the operator’s seat. 2. The hopper is not in the fully lowered position. 2. Lower the hopper completely.
