Reproduction
Power equipment is only as safe as the operator. If it is misused, or not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you.
Use common sense, and think through what you are doing. If you are not sure that the task you are about to perform can be safely done with the equipment you have chosen, ask a professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information you need to be aware of BEFORE you operate your unit as well as DURING operation.
Safe operating techniques, an explanation of the product’s features and controls, and maintenance information is included to help you get the most out of your equipment investment.
Operating Safety
Be sure to completely read the Safety Rules and Information found on the following pages. Also completely read the Operation section.
Tragic accidents can occur with children. Do not allow them any­where near the area of operation. Children are often attracted to the unit and mowing activity. Never assume that children will remain where you last saw them. If there is a risk that children may enter the area where you watch them.
Slope Operation
You could be seriously injured or even killed if you use this unit on too steep an incline. Using the unit on a slope that is too steep or where you don’t have adequate footing or traction can cause you to lose control or slip and fall.
You should not operate on inclines with a slope greater than 10 degrees, which is a 3.5 ft (1,5 m) rise over 20.0 ft (6,0 m). Always mow across slopes, never up and down.
Also note that the surface you are mowing can greatly impact con­trol. Wet grass or leaves can seriously affect your footing and trac­tion on a slope.
If you feel unsure about operating the unit on an incline, don’t do it. It’s not worth the risk.

Figure 14: Draining the engine oil
IMPORTANT: Drain the fuel tank before tipping the machine. 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.

WARNING
!
6. Carefully fold the handles, flexing the control cables to prevent cable damage.
7. Store the mower in a shed or other dry area, pro­tected from weather.
Fuel System
There is no need to drain gasoline from the engine if a fuel stabilizer is added according to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel system before storage.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved con­tainer. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.
Prepare the mower for “end of season” storage as fol­lows:
1. Disconnect the spark plug wire and secure away from the spark plug.
2. Drain the fuel tank and let the engine run until all fuel is out of the carburetor.
NOTE: If using a fuel stabilizer, there is no need to drain the fuel tank. Refer to the section entitled ‘Fuel System’.
3. Use a brush or compressed air to remove loose debris, then use a damp cloth to wipe down the unit.
4. Tilt the mower up on its rear wheels and inspect the underside of the deck. (Do not tilt the mower with the spark plug or carburetor down.) Scrape away stubborn 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.

WARNING
!
3. Reinstall the transmission plug.
4. Check the grease level after each 25 hours of operation.
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 17). 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 lb-ft (54 N.m).
4. Check the blade for sharpness, wear and damage. Refer to the Section entitled “Blade Wear Limits”.
