SECTION 11:  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
completely 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,
disconnect battery cables. Removing battery
from unit is recommended.

6.

Store unit in a clean, dry area. Do not store next
to corrosive materials, such as fertilizer.

NOTE: 

When storing any type of power equipment

in an unventilated or metal storage shed, care
should be taken to rustproof the equipment. Using a
light oil or silicone, coat the equipment, especially
any chains, springs, bearings and cables.
