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 16).
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 15). • Reel-drive-pulley position: You can set the reel-drive pulleys in 2 positions; refer to your cutting unit Operator’s Manual.
2. Ensure that the traction and reel-drive controls are in the NEUTRAL position. 3. Start the engine; refer to Starting the Engine (page 18). 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.
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 21). • To shut the fuel valve, turn the fuel-shutoff lever away from the recoil starter handle (Figure 21). g274946 Figure 19 1.

Slope Safety • Keep bystanders and children out of the operating • • • • • • • • • • • • • • • area. If co-workers must be present, use caution and ensure that the grass basket is installed on the machine. Operate the machine only in good visibility to avoid holes or hidden hazards. Do not operate the machine when there is the risk of lightning. Use care when mowing on wet grass. Poor footing could cause a slip-and-fall accident. Keep your hands and feet away from the cutting unit.
2. Operating Tips Ensure that the fuel-shutoff valve is open; refer to Opening and Closing the Fuel-Shutoff Valve (page 17) 3. Move the On/Off switch to the ON position. 4. Use the throttle control to increase the engine speed. 5. Move the choke lever halfway between the CHOKE and RUN positions when starting a cold engine; refer to Using the Choke Lever (page 17) 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.
Engaging or Disengaging the Transmission Installing the Transport Wheels 1. Move the kickstand to the TRANSPORT-WHEEL-SERVICE position; refer to Kickstand (page 12) 2. Slide a wheel onto an axle (Figure 24). 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. Check the reel-to-bedknife adjustment. Check the height-of-cut adjustment. Touch up damaged paint. Clean the machine.
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 28 1. Dipstick 1. Shut off the engine and wait for all moving parts to stop; refer to Shutting Off the Engine (page 20). 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 32). g274532 Figure 33 1. Traction cable 2. Jam nut g274480 Figure 32 1. Clutch cover 2. 2. Bolt Loosen the jam nuts and adjust the traction cable so that a 1.1 mm (0.
Adjusting the Service/Parking Brake Adjust the service/parking brake if it slips during operation. 1. Engage the parking brake. 2. Using a spring scale, apply a force on the service-brake lever (Figure 35). The parking brake should release when you attain a force of 16 to 18 kg (35 to 40 lb). If the parking brake does not release within this amount of force, adjust the brake cable. g345043 Figure 36 1. Front-cable jam nut 2. Rear jam nut g304663 Figure 35 1. Apply force to release the parking brake.
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 15). 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 7 until a speed between 3,350 to 3,550 rpm is attained. If you use the machine in a country that complies to CE standards, adjust the high idle speed to the following specifications: • 1018 machines: 3,000 rpm • 1021 and 1026 machines: 3,150 rpm 4. Shut off the engine. 5.
Tightening the Handle-Isolation Hardware Service Interval: After the first 20 hours 1. Position the machine on a level surface. 2. Loosen the bolt and nut as shown in Figure 42. g289358 Figure 42 g315331 1. Bolt Figure 41 1. Thottle-control stop 7. 2. Nut (machines with a flange nut only) 3. Push the handle as far forward as possible. 4. While supporting the handle, torque the bolt and nut that you loosened in step 2 to 68 to 75 N∙m (50 to 55 ft-lb).
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.
Adjusting the Reel-Driveshaft Position You can adjust the reel driveshaft position by adjusting the reel-drive-assembly position: 1. Loosen the bolt shown in Figure 47. g304660 Figure 47 1. Reel-drive assembly g333188 2. Bolt Figure 46 1. Socket-head screw 4. 2. Cutting-unit-drive coupler Slide the cutting-unit-drive coupler onto the transmission driveshaft (Figure 46). Rotate the reel-drive assembly so that the reel driveshaft is properly aligned with the transmission driveshaft. 3.
