Safety Safe Operation Practices for Ride-on (riding) Rotary Lawnmower Machines Preparation 1. While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals. Training 2. Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine. 3. WARNING – Petrol is highly flammable. 1. Read the instructions carefully.
Safety Operation 7. Watch out for traffic when crossing or near roadways. Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. 8. Stop the blades rotating before crossing surfaces other than grass. 2. Mow only in daylight or in good artificial light. 9. 3. Before attempting to start the engine, disengage all blade attachment clutches and shift into neutral.
Safety 15. Stop the engine and disengage drive to attachment • before refuelling; • before removing the grass catcher; • before making height adjustment unless adjustment can be made from the operator’s position. 16. Reduce the throttle setting during engine run-out and, if the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing. Maintenance and Storage 1. Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. 2.

Operation Think Safety First Please carefully read all the safety instructions and symbols in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. Controls Become familiar with all the controls (Fig. 17) before you start the engine and operate the machine. Recoil Starter – Pull recoil Starter handle to start engine. Fuel Shut–off Valve – (Under fuel tank) Close fuel shut–off valve when transporting or storing mower.
Operation Parking Brake Always set the parking brake when you stop the machine or leave it unattended. Setting the Parking Brake 1. Pull the upper control bar (Fig. 18) rearward and hold it in this position. 2. Lift the parking brake lock (Fig. 18) up and gradually release the upper control bar. The brake lock should stay in the set (locked) position. Releasing the Parking Brake 1. Pull rearward on the upper control bar (Fig. 18). Lower the parking brake lock to the released position. 2.
Operation Starting and Stopping the Engine 2 Starting 1. Make sure spark plug wire(s) are installed on spark plug(s) and fuel valve is open. 2. Move the shift lever to neutral, set the parking brake and turn ignition key to RUN. 3. Move the throttle control to CHOKE position before starting a cold engine. Note: 4. A warm or hot engine usually does not require any choking. To start a warm engine, move throttle control to FAST position.
Operation Operating Mower Blade Control (PTO) The Safety Interlock System The blade control switch (PTO) in conjunction with the blade control bail engages and disengages power to the electric clutch and mower blades. Engaging the Mower Blades (PTO) 1. Pull on the upper control bar to stop the machine (Fig. 20). 2. To engage blade, squeeze blade control bail against upper control bar 3. Press rocker switch forward “ON”. Hold blade control bail against control bar while operating. 4.
Operation Driving Forward or Backward The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the “FAST” position for best performance. Forward 1. To go forward, move the shift lever to a forward gear. 2. Release the parking brake: refer to Releasing the Parking Brake, page 21. 3. Slowly press on the upper control bar to move forward (Fig. 21). To go straight, apply equal pressure to both ends of the upper control bar (Fig. 21).

Maintenance Cleaning the Foam and Paper Elements Air Cleaner 1. Service Interval/Specification Foam Element Foam Element: Clean and re-oil after every 25 operating hours. A. Wash the foam element in liquid soap and warm water. When the element is clean, rinse it thoroughly. Paper Element: Replace after every 100 operating hours. B. Dry the element by squeezing it in a clean cloth. C. Put one or two ounces of oil on the element (Fig. 23). Squeeze the element to distribute the oil.
Maintenance 2. Paper Element Engine Oil A. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 24). Service Interval/Specification B. Change oil: Inspect the element for tears, an oily film, and damage to the rubber seal. IMPORTANT: Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene. Replace the paper element if it is damaged, defective, or cannot be cleaned thoroughly. • After the first 8 operating hours.
Maintenance Checking Oil Level Changing/Draining Oil 1. 1. Start the engine and let it run five minutes. This warms the oil so it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. 3. Place a pan below the oil drain. Remove the oil drain plug (Fig. 26). 4.
Maintenance Checking the Spark Plug Spark Plug 1. Service Interval/Specification Look at the center of the spark plug(s) (Fig. 28). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. Check the spark plug(s) after every 200 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug.
Maintenance Greasing and Lubrication Service Interval/Specification Grease the wheel bearings every 8 operating hours and the transmission couplers every 250 operating hours. Grease more frequently when operating conditions are extremely dusty or sandy. Grease Type: General-purpose grease. 2155 Figure 30 How to Grease 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. Tire Pressure 2.
Maintenance Brake Always set the parking brake when you stop the machine or leave it unattended. If the parking brake does not hold securely, an adjustment is required. Adjusting the Brake The brake lever is on the upper control bar (Fig. 17). If the parking brake does not hold securely, an adjustment is required. 1. Check the brake before you adjust it; refer to Checking the Brake, page 31. 2. Release the parking brake; refer to Releasing the Parking Brake, page 21. 3. Remove the belt cover (Fig.
Maintenance Fuel Tank Draining The Fuel Tank 1 POTENTIAL HAZARD • In certain conditions gasoline is extremely flammable and highly explosive. WHAT CAN HAPPEN • A fire or explosion from gasoline can burn you, others, and cause property damage. HOW TO AVOID THE HAZARD • Drain gasoline from the fuel tank when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. • Never drain gasoline near an open flame or where gasoline fumes may be ignited by a spark.
Maintenance Fuel Filter Replacing the Drive Belt Service Interval/Specification 1. Remove belt guard, not shown for clarity. Replace the fuel filter after every 100 operating hours or yearly, whichever occurs first. 2. Remove top capscrew securing idler support and idler bracket to rear frame (Fig. 35). 3. Loosen bottom two mounting screws enough to allow belt to pass between drive pulley and idler support (Fig. 35). 4. Raise wheel off ground enough to allow belt removal. 5.
Maintenance Replacing the Traction Belt Adjusting the Electric Clutch 1. Raise the front of the machine and hold with jack stands. Remove lower shield (4) bolts. The clutch is adjustable to ensure proper engagement and proper braking 2. Disconnect in–line wire connector from wire harness to electric clutch. 1. To adjust clutch, tighten or loosen adjusting nuts (Fig. 36). 3. Remove left front engine mounting bolt securing clutch retainer to frame (Fig. 36).
Maintenance Battery 3. Service Interval/Specification Check the electrolyte level in the battery every 50 hours. Always keep the battery clean and fully charged. Use a paper towel to clean the battery case. If the battery terminals are corroded, clean them with a solution of four parts water and one part baking soda. Apply a light coating of grease to the battery terminals to prevent corrosion.
