OFF-SEASON STORAGE
If the machine is to be inoperative for a period longer
than 30 days, prepare for storage as follows.
1. Clean the engine and the entire unit thoroughly.
2. Lubricate all lubrication points. Wipe the entire
machine with an oiled rag to protect the surfaces.
3. Refer to the engine manual for correct engine
storage instructions. The engine must be com-
pletely drained of fuel to prevent gum deposits
from forming on essential carburetor parts, fuel
lines and fuel tanks.
4. Charge battery fully. The battery loses some of
its charge each day when the unit is not used.
NEVER store battery without a full charge.
Recharge battery before returning to service or
every two months, whichever occurs first.
5. When storing unit for extended periods, discon-
nect battery cables. Removing battery from unit is
recommended.
