If this is not possible, refuel such equipment with a portable container rather than from a fuel-dispenser nozzle. Before Operation • Keep the nozzle in contact with the rim of the fuel tank or container operating at all times until fueling is complete.
Filling the Fuel Tank 1. Adjusting the Clip Rate Clean around the fuel-tank cap and remove the cap from the tank (Figure 14). Fill the fuel tank to the bottom of the tank-neck opening; refer to your engine Operator’s Manual. The clip rate is determined by the following machine settings: • Reel speed: You can adjust the reel speed to a high or low setting; refer to Adjusting the Reel Speed (page 14). Important: Do not overfill the tank with fuel.
4. Set the throttle control to SLOW, tip the front of the machine up, gradually engage the traction drive, and slowly increase the engine speed. 5. Adjust the throttle to operate the mower at the desired ground speed and transport the machine to the desired destination. Transporting the Machine Using a Trailer Use a trailer to transport the machine a considerable distance. Use caution while loading and unloading the machine onto the trailer. 1. Carefully drive the machine onto the trailer. 2.

During Operation – Shut off the machine and remove the key (if equipped). – Wait for all movement to stop. During Operation Safety • Shut off the machine before emptying the basket. • Do not touch the engine, muffler, or exhaust pipe General Safety while the engine is running or soon after it has shut off because these areas could be hot enough to cause burns.
Operating Tips • Do not operate a machine under any conditions where traction, steering, or stability is in question. Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive may result in sliding and a loss of braking and steering. The machine can slide even if you stop the drive. Important: Grass clippings act as a lubricant when mowing.
Shutting Off the Engine 1. Release the clutch bail. 2. Move the throttle control to the SLOW position. 3. Move the On/Off switch to the OFF position. 4. Close the fuel-shutoff valve before you store or transport the machine After Operation After Operation Safety General Safety • Shut off the machine, remove the key (if equipped), and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.
Installing the Transport Wheels Engaging or Disengaging the Transmission 1. Move the kickstand to the TRANSPORT-WHEEL-SERVICE position; refer to Kickstand (page 11) 2. Slide a wheel onto an axle (Figure 21). You can disengage the drum from the transmission to allow the machine to be maneuvered. Disengage the transmission when you need to move the machine without starting the engine (e.g., performing maintenance in an enclosed area).
Maintenance WARNING Failure to properly maintain the machine could result in premature failure of machine systems, causing possible harm to you or bystanders. Keep the machine well maintained and in good working order as indicated in these instructions. Note: Determine the left and right sides of the machine from the normal operating position. Important: Do not tip the machine at an angle greater than 25°.
Daily Maintenance Checklist Important: Duplicate this page for routine use. Maintenance Check Item For the week of: Mon. Tues. Wed. Thurs. Fri. Check the brake-lock-lever operation. Check the fuel level. Check the engine-oil level. Check the air filter. Clean the engine cooling fins. Check for unusual engine noises. Check for unusual operating noises.

Adjusting the Service/Parking Brake • To increase the cable tension, loosen the front-cable jam nut and tighten the rear jam nut (Figure 33). Repeat step 2 and adjust the tension if necessary. Adjust the service/parking brake if it slips during operation. 1. Disengage the parking brake. 2.
Adjusting the Reel-Control Cable To remove slack from the reel-control cable, perform the following steps: 1. Move the reel-speed-control knob to the high-reel-speed position; refer to Adjusting the Reel Speed (page 14). 2. Loosen the rear jam nut and tighten the front jam nut (Figure 34). g344197 Figure 33 1. Front-cable jam nut 3. Brake cable 2. Rear jam nut g311125 Figure 34 1. Rear jam nut 3. Reel-control cable 2.
Note: Ensure that the engine is at a normal operating temperature before you adjust the throttle cable. 2. Start the engine and use the throttle control to decrease the engine speed to low idle. 3. Observe the low-idle engine speed on your tachometer. The ideal range for high idle (for use in non-CE-compliant countries) is 3,350 to 3,550 rpm. If the tachometer shows a speed below 3,350 or above 3,550 rpm, perform steps 4 through 6 until a speed between 3,350 to 3,550 rpm is attained.
Cutting Unit Maintenance Blade Safety Use care when checking the reel cutting-unit. Wear gloves and use caution when servicing the reel. A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death. • Inspect the blades and bedknives periodically for excessive wear or damage. • Use care when checking the blades. Wear gloves and use caution when servicing them.
Backlapping the Cutting Unit Removing the Cutting Unit Note: The hex tube disengages if you engage the reel drive when the cutting unit is removed. 1. Move the kickstand to the CUTTING-UNIT-SERVICE position; refer to Kickstand (page 11). 2. Remove the grass basket (if equipped). 3. Move the collar (Figure 38) into the transmission-shaft groove. To backlap the cutting unit, use the Access Backlap Kit (Model 139-4342); refer to the operating instructions in the kit Installation Instructions.
Storage Storage Safety • Shut off the engine, remove the key (if equipped), and wait for all movement to stop before you leave the operator’s position.
