3.4 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 fuel from fuel tank and let engine run until 
all fuel is out of the carburetor. 
2.
  Disconnect and remove the spark plug wire 
away from spark plug before any other 
preparations are made!
 
3. Tape all openings closed to prevent spraying 
water into exhaust or air intakes during washing. 
4.  Tilt mower up on its rear wheels and thoroughly 
clean the underside of the deck. Do not tilt mower 
with 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 transfer 
rod clip and remove ground speed control rod 
before folding handles. 
7.  Loosen 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.
