CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. Safe Operating Practices 1 The following instructions are from ANSI standard B71.4—1999. m–4189 Figure 1 Training 1. Location of the model and serial numbers • Read the Operator’s Manual and other training material. If the operator(s) or mechanic(s) can not read English it is the owner’s responsibility to explain this material to them.
Operation Maintenance and storage • Never run an engine in an enclosed area. • Only operate in good light, keeping away from holes and hidden hazards. • Disengage drives, set parking brake, stop engine and remove key or disconnect spark plug wire. Wait for all movement to stop before adjusting, cleaning or repairing. • Be sure all drives are in neutral and parking brake is engaged before starting engine. Only start engine from the operator’s position.
• Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them. General Operation • Allow only responsible adults who are familiar with the instructions to operate the machine. • Mow slopes side–to–side. • Be sure the area is clear of other people before mowing. Stop the machine if anyone enters the area. DO NOT • Do not mow slopes greater than 15 degrees. • Do not mow in reverse unless absolutely necessary.

Gasoline and Oil Recommended Gasoline Warning Use Unleaded Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness. Important Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.

If brake adjustment is required, remove hairpin cotter and washer securing brake rod fitting to idler bracket (Fig. 14). 3. Check the gap between upper control bar and fixed bar with wheel drive fully engaged. Gap should be approximately 1 to 1-1/4 inch (25–32 mm) (Fig. 12). 7.
Operation Upper Control Bar – Shift to desired gear and push forward on control bar to engage forward traction operation and pull back to brake. Pull right side of control bar to turn right and left side to turn left. Note: Determine the left and right sides of the machine from the normal operating position. Lower Control Bar – Shift transmission to reverse and squeeze the lower control bar and handle together to engage rearward traction operation.
Stopping the Engine 2. Lift the parking brake lock (Fig. 17) up and gradually release the upper control bar. The brake lock should stay in the set (locked) position. 1. Move the throttle lever to slow (Fig. 18). 1. Pull rearward on the upper control bar (Fig. 17). Lower the parking brake lock to the released position. Note: If the engine has been working hard or is hot, let it idle for a minute before turning the ignition key off. This helps cool the engine before it is stopped.
Testing the Safety Interlock System 4. Repeat procedure to engage mower blades if blade control bail is released. 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. 2 1 3 1. Set the parking brake and start the engine; refer to Starting and Stopping the Engine, page 18 2. Squeeze the blade control bail against upper control bar.

Servicing the Air Cleaner Important worn. Replace the foam element if it is torn or Service Interval/Specification ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ ÓÓÓÓÓÓÓ 2 Foam Element: Clean and re-oil after every 25 operating hours. 1 Paper Element: Clean after every 100 operating hours. Replace after every 300 operating hours or yearly, which ever occurs first. Note: Service the air cleaner more frequently (every few hours) if operating conditions are extremely dusty or sandy.
3. Install the air cleaner cover and secure latches (Fig. 23). 1 2 Servicing the Engine Oil 3 Service Interval/Specification Change oil: • After the first 8 operating hours. • After every 100 operating hours. Note: Change oil more frequently when operating conditions are extremely dusty or sandy. Figure 26 1. Oil dipstick 2. Metal end Oil Type: Detergent oil (API service SE, SF, SG, SH or higher) 3.

Change the Engine Oil Filter Servicing the Spark Plug Service Interval/Specification Service Interval/Specification Replace the oil filter every 200 hours or every other oil change. Check the spark plug(s) after every 100 operating hours. Make sure the air gap between the center and side electrodes is correct before installing the spark plug. Use a spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap.
Checking the Spark Plug 2. Clean the grease fittings with a rag. Make sure to scrape any paint off the front of the fitting(s). 1. Look at the center of the spark plug(s) (Fig. 30). 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. 3. Connect a grease gun to the fitting. Pump grease into the fittings until grease begins to ooze out of the bearings. Important Never clean the spark plug(s).
Checking the Tire Pressure 1. Check the brake before you adjust it; refer to Checking the Brake, page 26. Service Interval/Specification 2. Release the parking brake; refer to Releasing the Parking Brake, page 18. Maintain the air pressure in the front and rear tires as specified. Check the pressure at the valve stem after every 50 operating hours or monthly, whichever occurs first (Fig. 33). Check the tires when they are cold to get the most accurate pressure reading. 3.
1. Park the machine on a level surface, to assure fuel tank drains completely. Then disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key. 4. Remove the filter from the fuel lines. 2. Close fuel shut–off valve at fuel tank (Fig. 35). 6. Open fuel shut-off valve at fuel tank (Fig. 35). 5. Install a new filter and move the hose clamps close to the filter. 3.

9. Remove the spark plug(s) and check its condition; refer to Servicing the Spark Plug, page 24. With the spark plug(s) removed from the engine, pour two tablespoons of engine oil into the spark plug hole. Now use the starter to crank the engine and distribute the oil inside the cylinder. Install the spark plug(s). Do not install the wire on the spark plug(s). 11. Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer. 12.
PROBLEM Abnormal vibration. Machine does not drive. POSSIBLE CAUSES CORRECTIVE ACTION 1. Engine mounting bolts are loose. 1. Tighten engine mounting bolts. 2. Loose engine pulley, idler pulley, or blade pulley. 2. Tighten the appropriate pulley. 3. Engine pulley is damaged. 3. Contact Authorized Service Dealer. 1. Shift lever is in neutral. 1. Move shift lever to a drive gear position. 2. Traction belt is worn, loose or broken. 2. Change Belt. 3. Traction belt is off pulley. 3. Change Belt.
