End of Season and Storage
BEFORE PERFORMING ANY MAINTENANCE PROCEDURE OR INSPECTION, STOP THE ENGINE AND WAIT
FIVE (5) MINUTES TO ALLOW ALL PARTS TO COOL. DISCONNECT THE SPARK PLUG WIRE, KEEPING IT
AWAY FROM THE SPARK PLUG.
NOTE: Please refer to the Engine Owner's Manual for Engine-specific procedures.
•
Change the oil.
•
Remove the Spark Plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the
Plug and crank the Engine for a couple of seconds using the Electric Starter. This will coat the
piston and seat the valves to prevent moisture buildup.
•
Clean/replace the Air Filter.
•
Clean dirt and debris from the Cylinder Head Cooling Fins, Blower Housing, Debris Screen, and
Muffler area of the Engine.
•
Replace the Fuel Filter.
• If your DR WIDE-CUT LAWN MOWER will be idle for more than 30 days, we recommend using a
gas stabilizer. This will prevent sediment from gumming up the Carburetor. If there is dirt or
moisture in the gas or Tank, remove it by draining the Tank. Completely fill the Tank with fresh,
unleaded gas and add the appropriate amount of stabilizer or gasoline additive. Run the Engine for
a short time to allow the additive to circulate. Close the Fuel Shut-Off Valve, if your machine is
equipped with one, to prevent Carburetor overflow and leakage.
•
Store the Battery in a dry area that will not freeze. If you will not use the machine over a long
period, charge the Battery every four to six weeks. See page 26.
• Remove any wrapped weeds from the Blade Bearing Housings. Clean grass and debris from the
top and underneath the Mower Deck with a stiff brush.
•
Check the Blades for nicks and wear. Remove the Blades and sharpen, or have them professionally
sharpened if needed. Never try to straighten a bent Blade. Dull or bent Blades can cause excessive
vibration and wear.
•
Perform the lubrication as outlined on pages 28 and 29.
