WARNING

!

DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Disconnect spark plug wire and secure away from spark plug. Engine and components are HOT. Avoid serious burns, allow sufficient time for all components to cool. Wear heavy leather gloves when handling or working around cutting blades. Blades are extremely sharp and can cause severe injury.

Check Mower Blade

1.Disconnect the spark plug wire and secure the end away from the plug.

2.Tilt the mower up on its rear wheels for access to the blade cap screw (A, Figure 19). Do not tilt the mower with the spark plug or carburetor down.

Important: Drain the fuel tank before tipping the mower. DO NOT tip the machine with the carburetor or spark plug down. Oil from the crankcase will saturate the air filter and cause the engine to be hard to start or not start at all. If contamination does occur, the air filter will have to be replaced.

3.Check the torque of the blade cap screw. Recommended torque should be 40 ft. lbs.

4.Check the blade for sharpness, wear and damage. Refer to the Section entitled “Blade Wear Limits”.

Check Transmission Poly-V Belt

1.Visually check the poly-v belt for cracking, fraying, sev- ered or exposed belt strands. If worn or damaged, replace the belt before operating the mower.

Service - Periodic

Perform all maintenance as described in the “Service Schedule” section of this manual.

Engine

Service the engine according to the engine owner’s manual.

Air Filter

Refer to the engine owner’s manual for service instructions.

Engine Oil

Refer to the engine owner’s manual for service instructions.

Storage Procedure

Refer to the Engine Owner’s Manual for directions regarding engine storage preparations. Prepare the mower for “end of season” storage as follows:

1.Drain the fuel from the fuel tank and let the engine run until all fuel is out of the carburetor.

2.Disconnect and remove the spark plug wire away from the spark plug before any other preparations are made!

3.Tape all openings closed to prevent spraying water into the exhaust or air intakes during washing.

4.Tilt the mower up on its rear wheels and thoroughly clean the underside of the deck. Do not tilt the mower with the spark plug or carburetor down. Scrape away any accumulation of grass with a putty knife and/or wire brush.

5.Lubricate all exposed metal with a light coating of oil to prevent corrosion.

6.On self-propelled models, disconnect the transfer rod clip and remove the ground speed control rod before folding the handles.

7.Loosen the handle knobs. Carefully fold the handles forward, “flexing” the control cables to prevent cable damage.

8.Store the mower in a shed or other dry area, protected from weather.

Maintenance

Check Engine Drive Belt

1.Visually check the engine drive belt for cracking, fraying, severed or exposed belt strands. If worn or damaged, replace the belt before operating the mower.
