Filling the Fuel Tank • Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, refuel such equipment with a portable container rather than from a fuel-dispenser nozzle. 1. • Keep the nozzle in contact with the rim of the fuel tank or container operating at all times until fueling is complete. Clean around the fuel-tank cap and remove the cap from the tank (Figure 13).
Adjusting the Clip Rate 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). • Reel-drive-pulley position: You can set the reel-drive pulleys in 2 positions; refer to your cutting unit Operator’s Manual.
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 During Operation Safety General Safety • The owner/operator can prevent and is responsible • • g273508 Figure 16 1. Choke lever—CHOKE position • 2. Choke lever—RUN position • Opening and Closing the Fuel-Shutoff Valve • Control fuel flow to the engine with the fuel-shutoff valve as follows: • To open the fuel valve, turn the fuel-shutoff lever • toward the recoil starter handle (Figure 17).
• Do not operate a machine under any conditions – Shut off the machine and remove the key (if equipped). 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. – Wait for all movement to stop. • Shut off the machine before emptying the basket.
Operating Tips Important: Grass clippings act as a lubricant when mowing. Operating the cutting unit excessively without grass clippings can damage the cutting unit. • Mow the greens in a straight back-and-forth direction across the green. • Avoid circular mowing or turning the machine on the greens areas to prevent scuffing. • Turn the machine off the green by raising the cutting reel (pushing the handle down) and performing a tear-shaped turn on the traction drum (Figure 18). g309985 Figure 19 1.
Installing the Transport Wheels 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 1. Move the kickstand to the TRANSPORT-WHEEL-SERVICE position; refer to Kickstand (page 11) 2. Slide a wheel onto an axle (Figure 20).
Engaging or Disengaging the Transmission 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). Before you operate the machine, ensure that you engage the transmission. 1. Locate the traction-engagement lever on the transmission gearbox (Figure 18). 2 1 3 g309986 Figure 21 1.

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.

Pre-Maintenance Procedures Engine Maintenance Preparing the Machine for Maintenance • Do not change the governor speed or overspeed Engine Safety the engine. • Run the engine dry or remove the fuel with a hand pump; never siphon the fuel. If you must drain the fuel tank, do it outdoors. WARNING While you are maintaining or adjusting the machine, someone could start the engine. Accidentally starting the engine could seriously injure you or other bystanders.
Changing the Engine Oil Service Interval: After the first 20 hours/After the first month (whichever comes first) Every 100 hours/Every 6 months (whichever comes first) WARNING Oil may be hot after the engine has been run, and contact with hot oil can cause severe personal injury. Avoid contacting the hot engine oil when you drain it. g266053 Figure 24 1. Dipstick 1. Shut off the engine and wait for all moving parts to stop; refer to Shutting Off the Engine (page 19). 2.
Note: Ensure that dirt and debris do not enter the air duct leading to the carburetor. Note: Ensure that no dirt or debris from the air-cleaner cover fall into the base. 4. Remove the foam and paper elements from the base. 5. Remove the foam element from the paper element. 6. 11. Install the air-cleaner elements and ensure that they are properly positioned. Install the lower wing nut. 12. Install the cover and install the upper wing nut to secure it.
Controls System Maintenance Adjusting the Traction Cable Adjust the traction cable to achieve a gap of 1.1 mm (0.045 inch) between the friction disc and the pressure plate. 1. Access the friction disc and pressure plate by removing the clutch cover (Figure 28). g309987 Figure 29 1. Traction cable g274480 Figure 28 1. Clutch cover 2. 2. Bolt Loosen the jam nuts and adjust the traction cable so that a 1.1 mm (0.045 inch) gap is between the friction disc and the pressure plate (Figure 29 and Figure 30).
g304663 Figure 31 1. Apply force to release the parking brake. 3. Perform the following steps to adjust the brake-cable tension: • To increase the cable tension, loosen the front-cable jam nut and tighten the rear jam nut (Figure 32). Repeat step 2 and adjust the tension if necessary. g274479 Figure 30 1. Friction disc • To decrease the cable tension, loosen the rear jam nut and tighten the front-cable jam nut (Figure 32). Repeat step 2 and adjust the tension if necessary. 3. Gap—1.1 mm (0.
Adjusting the Reel-Control Cable Note: Ensure that the engine is at a normal operating temperature before you adjust the throttle cable. To remove slack from the reel-control cable, perform the following steps: 1. 2. Move the reel-speed-control knob to the high-reel-speed position; refer to Adjusting the Reel Speed (page 14). 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.
Tightening the Handle-Isolation Hardware 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. Service Interval: After the first 20 hours If you use the machine in a country that complies to CE standards, adjust the high idle speed to the following specifications: 1. Position the machine on a level surface. 2.
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.
