End of Season and Storage
BEFORE PERFORMING ANY MAINTENANCE, SHUT OFF THE ENGINE, ALLOW FIVE (5) MINUTES FOR
PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE. READ THE "SAFETY CONSIDERATIONS"
SECTION OF THIS MANUAL BEFORE PERFORMING ANY REPAIRS OR MAINTENANCE.
NOTE: Please refer to the Engine Owner’s Manual for engine-specific procedures.
•
Change the oil.
•
If your DR LEAF and LAWN VACUUM 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.
•
Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the
plug and pull the recoil starter rope until you feel strong resistance. This will coat the piston and
seat the valves to prevent moisture buildup.
•
Clean or replace the air filter.
•
Clean dirt and debris from the cylinder head cooling fins, blower housing, debris screen, and
muffler area of the engine.
•
Clean out residual debris from the Blower Hoses and Collector Box.
•
If you are going to use the DR LEAF and LAWN VACUUM as a Trailer during the end of season, we
recommend that you remove and store the engine in a dry location. See page 45.
•
For minimal storage space, you can disassemble the Collector Box by removing the Rear & Front
Panels, Centrifugal Separator (Top), and the Side Panels. The Collector Box pieces then can be
stacked against a wall in a convenient location. See page 16 for disassembly and re-assembly of
the Collector Box.
•
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 39.
