Operation DANGER In certain conditions during fueling, static electricity can cause a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed, because interior carpets or plastic truck-bed liners may insulate the container and slow the loss of any static charge.
Add the correct amount of fuel stabilizer/conditioner to the fuel, and follow the directions of the manufacturer. Filling the Fuel Tank Note: Fuel stabilizer/conditioner is most effective fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand. Note: Do not fill the fuel tank completely full. Fill the when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 1.
Checking the Engine-Oil Level Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level (page 41). Breaking in a New Machine New engines take time to develop full power. Mower decks and drive systems have higher friction when new, placing additional load on the engine. Allow 40 to 50 hours of break-in time for new machines to develop full power and best performance.
Entering the User Position Use the mower deck as a step to get into the user position (Figure 9). g000963 Figure 10 1. Safe Zone—use the machine here on slopes less than 15° or flat areas. 2. Danger Zone—use a walk-behind mower and/or a hand trimmer on slopes greater than 15° and near drop-offs and water. g029797 Figure 9 1. Mower deck 3. Water Think Safety First CAUTION Please read all safety instructions and symbols in the safety section.
Operating the Parking Brake Operating the Mower Blade-Control Switch (PTO) Always set the parking brake when you stop the machine or leave it unattended. The blade-control switch (PTO) starts and stops the mower blades and any powered attachments. Setting the Parking Brake Engaging the Blade-Control Switch (PTO) WARNING Note: Engaging the blade-control switch (PTO) with the throttle position at half or less causes excessive wear to the drive belts.

Note: You may need multiple attempts to start the engine when you start it the first time after the fuel system has been without fuel completely. g008946 Figure 16 Operating the Choke Use the choke to start a cold engine. 1. If the engine is cold, use the choke to start the engine. 2.
Starting and Shutting Off the Engine Note: You may need to attempt to start the engine multiple times when you start it for the first time after the fuel system has been without fuel completely. Starting the Engine 1. Raise the ROPS up and lock into place, sit on the seat, and fasten the seat belt. 2. Move the motion controls to the NEUTRAL-LOCK position. 3. Set the parking brake; refer to Setting the Parking Brake (page 21). 4. Move the blade-control switch (PTO) to the OFF position (Figure 20).
Understanding the Safety-Interlock System The safety-interlock system is designed to prevent the engine from starting unless: • The parking brake is engaged. • The blade-control switch (PTO) is disengaged. • The motion-control levers are in the NEUTRAL-LOCK position. The safety-interlock system also is designed to shut off the engine when you move the traction controls from the locked position with the parking brake engaged or if you rise from the seat when the PTO is engaged.
Testing the Safety-Interlock System CAUTION Machine can spin very rapidly. You may lose control of machine and injure yourself or damage the machine. • Use caution when making turns. • Slow the machine down before making sharp turns. Service Interval: Before each use or daily Test the safety-interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. 1.
Shutting Off the Machine To shut off the machine, move the traction-control levers to NEUTRAL, and then move them to the LOCKED position, disengage the power takeoff (blade-control switch (PTO), and turn the key in the ignition switch to the OFF position. Set the parking brake when you leave the machine; refer to Setting the Parking Brake (page 21). Remove the key from the ignition switch. CAUTION Children or bystanders may be injured if they move or attempt to operate the machine while it is unattended.
Adjusting the Height-of-Cut Pin The height of cut is adjusted from 25 to 140 mm (1 to 5–1/2 inches) in 6 mm (1/4 inch) increments by moving the clevis pin into different hole locations. g008955 Figure 27 Transport Lock Positions 1.
